Sound Oscilloscope

Great application. I use it for demonstrating and teaching sound physics. The ability to look at 9 to 18 seconds and then adjust the Amplitude in time scale is great. My only suggestion would be the ability to save a file.

perfect, just what I was looking for. easy to use and just enough controls to make it very useful. i love it that you can adjust amplitude and time base after you stop the readout.

Excellent App. I used the Osc mode in 100ms per vert. Interval to align my 5-tick per second Chelsea Boat Clock, picking up the ticks by vibration to the Tablet Mic. It WORKS! Great Freq. Analyser and Db wavemeter too!

Love the ability to change the scale on both axis. Would love the ability to move the grid I would have given it 5 stars otherwise

Excelent app very usefull.....i used this for most of my lab work..

I was looking for years for this app . thanks a lot .

its a cool app

Thank you

It's an important part of my mind and heart rate, while making it to the sound system. thanks

That's great! Really good. One little problem: 2 components of Fourier series isn't enough for describing difficult signals.

Sounds are neat!!

A well thought out app with professional features. I'm using it on a Samsung Galaxy Tab 4 8.0 and agree with all comments by reviewers so far. It's a pity the full potential of this program can't be realised through default acoustic coupling via the inbuilt microphone instead of by direct signal injection. I think strengthening the scope trigger could help to lock displayed waveforms better, as some drifting is noticeable but this doesn't detract from user enjoyment. I really would like to install Android OS on a flash drive and then test this app running properly on my laptop fed with home - made waveforms to the mic socket. Best regards.

Simply excellent! However, I would like to have more controls, specially in the FFT view such as FFT size, windowing function and noise floor adjustment. In the scope view it would be awesome to have specific controls to adjust the time base and H/V scaling.

Better than most o-scopes apps available. But the developer still need to address the huge delay in FFT mode.

1 remember settings. 2 Remember Peak levels. 3 some indication on whats changing when you press a button, especially on the time. Found DIGI+Sound Meter. Does EVERYTHING and more that Im looking for.

Hi, I hold no degrees, choosing to hang out in art classes for my 6 years of high school. I don't know the difference between a capacitor and a resistor, and anytime I've tried soldering anything it ends up in a spreading tin/lead puddle that spreads to all my other connections rendering my whole project useless. I don't know how an oscilloscope works, all I know about one is it starts out The Outer Limits. Or is it The Twilight Zone? I always get them confused with each other. But I just love all the wavy lines and could watch them for hours, and that's even without a high! Well done with your wavy line maker thingy!!!

I used it to check my mechanical metronome, piano and other similar things. Helped me a lot.

FFT is delayed by 9(!) seconds. Otherwise looks pretty good app.

I used it to adjust a pendulum clock to tick evenly. Admittedly this is a very specialized application. Microphone sensitivity is excellent on Galaxy S5.

Well educated holding two degrees, one degree in computer science , another in communications electronics .FCC GENERAL RADIO TELEPHONE LICENSE also- known as FCC 1ST Class License with Radar Endorsement . I have used a lot of test equipment this is extremely handy to have in my telephone I can tell natural sounds from man-made sounds with it and their relative sound levels if you know how to read the information.

Works great! I've tried a bunch of apps like this, and this is the best one I've found. Good sensitivity with my phone's mic. Thanks!

Very effective to demonstrate exccessive noise environment! Thanks

Very useful tool for acoustical observations.

Does dBm f f t and scope with wide range of time scale.

what did you use here? mediarecord or audiorecord?

Shows the sound wave, you can adjust the magnitude and time, fft is arguable..

, with 3 fonction , 0 to 20 second on screen , useful to me .

Does what it says

Several attempts to install the app have given message that 'Sound Oscilloscope can't be installed... Error Code 504'. I an using Samsung Galaxy S7 edge running Nogaut.

Ya man i m stoned and my fart looked pretty cool on the screen man
