Spectroid is a real-time audio spectrum analyzer with reasonable frequency resolution across the the entire frequency spectrum.

💬 FAQ 💬

Q: Why are the dB values negative?
A: Spectroid uses dBFS (Full Scale) where 0 dB is the maximum power that the microphone can measure, so the decibel values are negative because the measured power is less than the maximum power.

Q: Can I zoom in on the spectrum plot?
A: Yes, do a two-finger pinch-to-zoom gesture.

Q: Why are there discontinuities/gaps in the spectrum plot and waterfall?
A: Spectroid uses multiple FFTs overlapped in frequency in order to provide better frequency resolution at lower frequencies than a single FFT. The caveat of this method is varied impulse response and minor discontinuities in frequency. The upside is that it can efficiently produce a spectrum that better matches the frequency resolution of human audio perception. It's still probably not as good as your ears though!

  1. Jon Bogart-avatar

    Very cool! This app is a significant step towards making the tricorder from Star Trek a reality. No ads, no BS, just pure function. If only there were more developers like this person, then we'd be able to beam down with Kirk and Spock! Awesome app! Hopefully others will follow your no nonsense approach, and maximize the potential of this amazing technology.

  2. James Valente-avatar

    Free. Simple and easy to use. Safe to install. App permission is appropriate to what it does ... accesses the microphone to plot the spectrum analysis of sound in the room. No other permissions are requested nor required.

  3. Jacob Pierce-avatar

    I've tried just about every spectrograph app that I could find for Android and this is by far the best. I use it all the time, and it really helps me understand the sounds I'm hearing. I love that you can set the floor and the cutoff frequencies. The only thing it needs to be perfect is a way to save the data it captures without needing to take a screenshot.

  4. Ricardo Malla-avatar

    Great App, a couple of questions: 1. Is it possible to attach a professional microphone to make it more precise (getting a right DB setting)? 2. Can we some time of gauss meter probe to measure the electromwgnetic spectrum? And make this an EMF or RF spectrum analyzer?

  5. Kilos Noventa-avatar

    awesome. from a beginner's point of view, who is trying to tweak my car audio system to sound to my exact liking, this is exactly what I needed to understand really how low (or not) I need my basses to be, this tool allows me to put a number to the frequencies I want to target.

    Favorite app I have on my phone so far! See I hear voices sometimes that tell me to do bad things and they are constantly puting me down trying to lower my self worth. Well now with this amazing app if I question any iffy voices, I can see if a voice is physically real, visually! Could be a life saver. Thanks Spectroid!

  7. Scott H-avatar

    Great app for measuring ultrasound (up to 22 khz) and infrasound (under 18 hz), by looking at an active graph of all the audio frequencies present in your environment. You can explore all audio frequencies present. Simple and easy to use.

  8. Louie Gee-avatar

    Really slick display. Really responsive. Love it. The onnly thing is that I wish changing options like linear/logarithmic were one or two clicks instead of buried 4 or 5 clicks deep. But NOT a deal breaker for sure.

  9. Rema Chonga-avatar

    Very nice to have the decimations. Really helps to show lower frequencies instead of lots of upper frequencies. Being able to select window functions is also very helpful. I am using this app regularly.

  10. Rei SHIN-avatar

    This is really a great app! Is it possible to keep the waterfall log run for longer than a scren or save it out on disk? I want to run 24/7 and backup alld the records..

  11. Oscar Halse-avatar

    Works just as it should, no less, no more. When fighting feedback in a live setting, this is an invaluable tool every sound tech needs. There is no strong reason to use this specific spectrum analyzer, but this one will leve you plenty satisfied as there's nothing it does poorly. There's only so much you can do with a spectrum analyzer, and spectroid does it well enough.

  12. Tank R.-avatar

    Great app, I use it on many devices. Unfortunately it doesn't seem to read the mic on my old Galaxy Tab 3 10.1. For how old this device is im not surprised with apps that fail in random ways. Eventuality ill root and rom it, and when I do ill try again and report back!

    Not only is this a mathematical and computer science feat on its own (doing thousands of fourier series on your phone without it crashing), but it's also very fun and interesting to plau around with!

  14. Matthew Guidry-avatar

    It is simple and beautiful with the spectrogram as well as the real-time spectrum analyzer with automatic labeling of the peak amplitude frequency and a max hold function. It's very nice for interactive exploration of sound waves.

    Seems to work well. Haven't used it for why I got it yet. Looking to use it to find an annoying noise in my mustang.

  16. LCM Leaked-avatar

    Most accurate one I could find one play store. Another useful feature is that you can tweak sample rates. Still not enough features for me is why I have 3 different frequency analyzers

  17. Tyler Stout-avatar

    Awesome app. Only suggestion would be either a way to output the graphs to a file that you can load or picture or the ability to make the line a little bit thicker so it stands out more in screenshots. All of my screenshots the line looks like it's 5 pixels thick and it's hard to see. Also if you did picture or file outputs being able to caption them would be useful for when I do measurements I can know what each one is of.

  18. Thomas George-avatar

    Feature missing. The waterfall does not detect sounds over 10khz. It used to a few weeks ago. Can we fix this?

  19. Gord Law-avatar

    Appears to work as it should. Frequencies are spot on with what was expected when I compared it to known sources.

    Why do 2 devices, running on the same platform, same version, show different results, even when placed right next to each other? This is not a problem of this app though, it's the same with 3 other top audio measurement apps. Those show much worse differences in measurement.

  21. Richard Schamp-avatar

    I'm been looking for an app to be able to measure high frequency sounds that I can't hear and this is the 1st one I've seen that works

    Fun app to play with, even though I don't really do much that actually needs a spectrograph! Works brilliantly, thank you 😃

  23. jj parsons-avatar

    Its an okay app... Itd be better if I could save certain sounds and store them in an album so I can play them backwards and what not.

    This app does exactly what I need - displaying both the frequency and the decibel. The only thing lacking for my purpose were, being able to save a snapshot data file. Just to make it easier to compare 2 different recordings.

  25. Si Brax-avatar

    Really handy tool for a quick visual on the freq spectrum. I use it for for live sound engineering. Settled on this after trying about 5 others.

  26. Harkon Takala-avatar

    Works great, simple and easy to use, does exactly what it says it does. Small sized app so you can make space easily.

  27. Daniel Boone-avatar

    I have an odd use for this app. I hint for vacuum leaks utilizing my phone (sometimes a bluetooth microphone) and the app. Many minuscule leaks are audible, but not within human hearing. Has saved me a ton of time at work.

  28. Jacek Rogoz-avatar

    It was okay in Android 9 but it shows big dropout in signal at about 7kHz in Android 10. Why? I'm using it on Nokia 7 plus

  29. Gizzle Gar-avatar

    Does what it does, just wanted an app that tells me how loud sources are. This app does that VERY well and does it with some style and zero ads. Lots of options for how the info is taken in and displayed. I'm impressed.

  30. manuel sotelo-avatar

    Best one so far can you please add a piano overlay with notes similar to "wave candy" in fl studio

  31. Stuart Bruce-avatar

    Perfect. No ads. No distractions. It does exactly what it says - and very well. (It's also EXTREMELY useful for anyone experiencing auditory hallucinations. As long as I'm not in a very noisy place, I can determine what's in the consensus reality and what's in my private realities.) I'll be recommending this to others. Thank you!

  32. Carson Murray-avatar

    As a part time audio engineer, this is great for me. I tried it with a couple of other similar apps, and this one seemed to be the cleanest, most precise, and reliable. Awesome when I need a little help nailing down a feedback frequency or hiss in a new microphone 4 stars because I can only seem to get it to register up to 24kHz, when I need it up to 28kHz. Also would be nice to be able to export the data. Small complaints for a great app though.

  33. Aaron Davis-avatar

    Wonderful tool! Very simple, yet effective. Wouldn't change a thing.

  34. Steven Willis-avatar

    Very, very nice! I'll give 5 stars if you can add a time interval marker to the waterfall display, allow the waterfall display rate to be adjusted, and allow the waterfall display to be dragged to any size.

  35. Marcin Osada-avatar

    Great app, no annoying ads or permissions . You the best :)

  36. Sj-avatar

    I have been using this app for about 2 months to analyze a varying high frequency noise through the interior and exterior of my home and capture the db levels. I was surprised that it measures the frequency levels also! however, it would be extremely germane to my needs if the recording was also audible. It does not interface with a player to hear the sounds it records. I hope you work on that.

  37. Vishaal Kapoor-avatar

    This is one of those apps you feel good about rating because it does exactly what it says, and well. Feature request: It would be cool to be able to download the time/freq data.

  38. Doug Landers-avatar

    Seems to work pretty well and is very easy to operate. I will use it in an upcoming test to see how accurate and responsive it is. I don't see a way to have it record the audio track, that would be helpful. It would also be nice to be able to get the data from the spectrum and / or time history out to a text file. The only other thing that would be nice is to play the file back for review and to allow the speaker to also play back the audio and spectrum. I wished the test audio played through the speaker, as well. Great tool!

  39. Michael Gerety-avatar

    Absolutely the best app and I have been looking. I use it to check the frequency response for guitars to "see" the quality and make comparisons. I recently bought a guitar before prior to app. it was the only guitar that they had that worked for me but I suspected it was not all that good. After the app. I confirmed my suspicions AND now I know WHAT the problem is too. I will not buy another instrument without this app. Need to record files and display them together. Please?

  40. John Haine-avatar

    Wonderful app. Within 5 minutes of installing it I had diagnosed what was causing my acoustic noise problem. Thanks for making this available.

  41. Evan Reed-avatar

    Incredibly fluid app by far best way to analyze live sound around you. Was able to explore just how annoying the 291 Hz constant buzz was outside my window projecting at 65Db all day long from the city construction machinery... thanks Spectroid!

  42. Steven Zapata-avatar

    Looks awesome with certain types of music. Any music with a piano or harmonic type instrument shows up clearly when you use it. Kicks, snares, claps, and hi hats as well, if you know what to look for. Very useful in eyeballing certain melodies of songs if you can't pick which notes are played in your head. Useful and fun. Also note: the quality of the visualization is directly proportional to the microphone quality, distance from sound, and the volume of sound.

  43. Mike Smith-avatar

    This has to be one of the cleanest, most useful apps I have ever used. Great for just getting a general idea of what is happening with speaker setups. Used this last night at a live cafe setup to help zero in on some problem frequencies, and give confirmation of an EQ cut. Thank you so much for this!

  44. Matt Wilder-avatar

    Agree with all the other reviews, this is the best spectrum analyzer app on the play store! Dear dev, PLEASE add the ability to analyze audio files on local storage! One major use I and a whole community I'm familiar with online uses spectrum analyzers to validate that music in FLAC format is not just a mp3 upconverted to flac format which you can easily see right away based on the high frequency roll off. Even just a 1:1 play through with no rewind/ff would be wonderful!

  45. Zackeroo HQ-avatar

    Literally the best app I have downloaded in a while. I have had a bad history with android apps. They are no where near iOS apps quality. This app is different. It works so well and is perfectly accurate. Everything is perfect. It has everything I would have wanted as well as one more thing. Usually I always have to go and tweak the settings in apps to make them better. This is the first app which I tried so hard to find a setting to change and found nothing

    Very good, useful app. Thank you. Frequency measurement top on, amplitude probably too but of course my phone's mic is not calibrated.

  47. Chaz Mertes-avatar

    I absolutely love this app! I use it for determining motor speeds. Put a post it note on the shaft, let it run and run it like a card on a bicycle spoke!

  48. David Oraha-avatar

    This is great software man. Maybe one feature that would be great unless I have missed something, is a logging feature that maybe records sound as it analyses the audio. Maybe then SQL lite write to the local storage of the phone to be able to play back then read the analysis again. Honestly I would pay $$$ for that. Hahaha. Overall amazing app my friend!

  49. Nikolay Pelov-avatar

    Great app. It would be nice to be able to flatten the graph - take a reference in a quiet place and apply it to equalize/subtract the phone self noise. Ow and maybe peak walking - sort peaks by db and move to next peak by preasing + or - icon.the cursor is nice but it's hard to read harmonics - yoy have to place it exactly on the peak, which is not that easy. Keep up the good work. If you make a paid app for $4- 5 that has these features I would buy it

  50. A Google user-avatar

    Incredible app.... Probably the most useful app in this whole online store. Does exactly what it's supposed to. No ads annoy you. Lots of great features most would never understand unless you are an electrical engineer or audio engineer. Really stellar job with this app. Very accurate and you can use other mics then the one on your device.

  51. Chris Brown-avatar

    Perfect for my use, of ringing out an auditorium. Definitely would recommend

  52. Oni Iniuqrat-avatar

    Awesome functions and no ads. Old school the best ;P Good job...

  53. Dan Nguyen-avatar

    Great for sub crawls for your home theater. Sometimes I'm not sure if I can trust my ears, so it's nice to have something visual.

  54. Richard P-avatar

    While I don't use it professionally, as a former audio professional, 8 love it and use it.

  55. Robert M.-avatar

    It did what it was supposed to do. What ever sound comes through the mic is picked up. Maybe even pic up the Taos Hum.

    I just used it to check if my external microphone is working or not and didn't want to install others that seemed bloated. This is an extremely light app and the Spectrum display was useful to isolate internal vs external mic input. Those who wrote complain about spam caused by this app or total Android newbs and just plain paranoid. This app only gets access for recording audio, so can't get access to your phone number and cause spam.

    Hello! First let me tell you that I love your app and it is very useful for me. I wish to ask you a personal favour which could lead to improve even more the application. 1) please accept input not only by microphone but also from the phone sensors like the accelerometer, the gyroscope and even the compass (if present) the "noise" of the accelerometer (combining the 3 axys on different frequency ranges perhaps) could be very useful to diagnose vibrations, eartquakes or any sort of thing. same goes for all the other sensors. It seems complex but is very easy to read the sensors and just put the sensor reading in an array which is then fed to the FFT routine. 2) the waterfall seems slow... or not much readable, would be better to allow a zoom function like you did with the frequency display above. Alternatevely you can make it dependent on FFT size.. because the smaller that is the more "samples" you get. Thanks for reading.

  58. Gergő Lakatos-avatar

    Really great app, it does what it should. Just one question, why is the db scale reversed and starting from around -120? Wouldn't it be better to start from 0 and then go to positive values? Edit: Ok I see it in the FAQ. In that case how do I know my own phone's 0? I guess it is around 120 but would like to know it exactly.

  59. Frieder Guy-avatar

    I don't usually bother rating apps, but this is excellent. The ability to zoom to any portion of the chart and see meaningful level of detail even in the low bass region makes it hands down the most useful RTA I've seen. The only request I would make is for an iOS / iPadOS version too! (And maybe, for ultimate fanciness, the addition of IIR/FIR function could allow microphone calibration data, ambient noise exclusion etc, but maybe not, as bloat kills, and right now it's superb!) Thank you!

  60. Rob G-avatar

    Nice clean app. An option to change the DB scale from Reference (i.e. -30db) to Absolute (i.e. +70db) would be nice for evaluating how long the environment is.

  61. Old Shark-avatar

    excelent app... very intuitive... but I wish there was a clear way to upload a TXT calibration file to setup an external microphone... help on this, please!

  62. Dayasagar VS-avatar

    It has more features than every other spectrogram app out there, is very small and easy to use. And free ! Couldn't ask for more

    It looks pretty awesome, and seems to be very sensitive. I downloaded Spectroid because so many people commented that it was probably the most useful app in the entire app store, but that is lost on me. Would anyone mind giving me a few examples of what you could use this for in real life, please? I'm sure there are tons of things I can do now, but I have no idea what they are. 😳

  68. John Doe-avatar

    At first I thought this was fake, but I finally found a way to test it and by having my phone pick up audio from "My Song In Spectrogram" by Ryan Wyer. However, I'm not sure if it's my phone's mic or the app or something else but it shows a small picture. Sure, most phones aren't bigger than 6 inches but I feel like for this, there should be a way to replay the imaging and make it bigger

  69. Adam Ferestad-avatar

    This is an awesome program. I am doing some audio visualization animation and am looking for a song to feed into it that will drive it right. The only issue I am having is that I can't see the whole frequency range. I need linear scale and for some reason can only see from 1.5kHz to 4kHz. What setting am I missing?

  70. Teddy Budiwan-avatar

    Enjoyed the information, useful for analysis for room noise polution and sound profile. would love the ability to save.

  71. syed-avatar

    Its cool but not really useful. I mean you can see the spectrum; cool but can't record it, can't transfer or process audio recordings on it; useless.

    Holy spam batman! I should have paid attention to the reviews that co.plained about getting spam calls after installing this app. Less than 6 hours after installing it, I got my first one. I have been getting 4-5 spam calls a day since. I haven't installed anything else or signed up for anything elsewhere so it has to be this developer selling phone numbers to marketers. I've uninstalled but the damage is done. I would avoid if I were you. The app is good, the spam calls, not good...

    Spectroid is THE STRAIGHT-DOPE BUSINESS! I have scarce used an app so well designed and executed. I love the configurability of this app, which runs stably and never quits on me no matter how demanding my configuration options might be on my phone's processor. This is my go-to tool whenever investigating problematic acoustics or quickly spotting any unwanted, incidental harmonics in a music mix. Heck, I even use it to explore the sonic phenomenon around me. This is THE BEST SPECTRAL TOOL!

  83. P Novak-avatar

    Excellent! Well made. Does exactly what it says without excessive permissions and ads all over the place. Very impressed!

  84. Enis Ungan-avatar

    Very good adjustments available. Would be great if able to adjust flow rate on spectogram, e.g. 1 sec image at full scale display.

  85. Matt Rutter-avatar

    I'm seriously impressed with this app... I've been hunting for a way to measure engine revs, and this does the job beautifully... much better than any of the apps designed for the job. You do have to know what to look for, and how to calculate revs based on engine configuration, but once you know that, this works perfectly.

  86. John-avatar

    This is an EXCELLENT app. Written VERY well with super quick real-time graphics. This app helped tremendously with adjusting my new a/v receiver in finding the frequency of a standing wave making my bass sound too booming. Being able to pinch zoom in on any frequency range is extremely helpful. Good job!

  87. A Google user-avatar

    Beautifully presented app and a lot of fun. I keep thinking of new ways to use the data. present version has a small bug (on my phone anyway) if I don't turn off autorotation then the frequency amplitude heatmap /time trace is lost on rotation to landscape and not restored on return.

    I was dissapointed that there was no way to change the frequency thresholds. I wanted to take it above the human hearing of 20kHz but it's stuck at a maximum of 10kHz. I guess this is just a free toy to play around with, but I definitely would have liked to see more customizability.

    One of the best apps in it's kind. And free. I'm even willing to patreon! Thanks! Good job.

    Very nice and simple! Some things I had trouble with were: 1) switching to 96kHz sampling doesnt work (maybe it is not supported by my phone - SGS9) 2) change from log to linear X axis scale has no effect until the application is restarted. 3) increasing the number of FFT bins freezes the display completely

    Looks great. Option to record the graph and take screenshots would make it even better !

    Simply awesome for testing microphone, noise around you and how much audio your microphone can detect.

    It's basically a toy, but it does its job very good and well! :)

    I don't even remember what I originally downloaded this app for, but after opening it up a second time just now, I was reminded by how clean and responsive it is. Even just to watch the levels as I sit in a coffee shop or on a bus is fascinating.

    This is the best I have come across. The features are very useful. Was a lot of help with getting my home studio setup. The hold peak indication is great if you are trying to match levels in a specific sitting area.

    Great app. Simple, free and no ads. Just what I needed.

    No ads. Lots of functionality and options depending on application needs

    Technical detail to keep in mind: waterfall display is not time accurate. Under certain settings, low frequency area can be several tens of seconds out of sync with high frequency area on the same axis. Otherwise, settings left at defaults, app is somewhat useful.

    This app can certify whether you are actually crazy or not. Were it not for this app I would have never discovered that parking lots are the most terrifying places in the universe to be especially when you remember days long lost thinking you were actually alone just because you didn't actually see anybody around.

    Excellent app. Does exactly what it says with a simple clear interface. One request would be the ability to stop the acquisition and display that spectrum as a reference instead of the peak signal. Nice, useful program!
