Signal Generator

Does what it says on the tin App functions just fine. It's a bit limited, though. I would appreciate more info like reference benchmarks (eg: middle C), or some sort of visualisation of the signal being generated (eg: spectral analysis or waveform).

Superb! Does everything I want. Great app. Very useful for debugging circuits and such. It'd be cool to have more waveforms to choose from but I'm not gunna take a star off for that.

Awesome! Great signal generator!!!

Sound guy This app is great for tone sweaping speakers, simple yet effective. It moves in steps when you sweap it but whatever, it'sfree.

LAB CHECK AND RESULTS DONE WITH MY TEK 200MHz OSCILLOSCOPE, WITH A 100 OHM LOAD ON PHONE OUTS... I AM USING A NEXUS7 32G TABLET. 1. LOVE THE SIMPLICITY. 2. SINE WAVE VERY JITTERY, ESPECIALLY AT HIGH FREQS. 3. NOISES SEEM FINE... Good minimalistic approach, guys, but check out FuncGen (also free). Beats em all. And then, you can get AudioTool, but you pay... Probably good on phones to just generate pink noise into systems...or bother your friends. Keep up the work guys, can be better for us pros.

Great for studying I use this when studying in places with loud or annoying music. Put some headphones in, hit "pink noise". Works great. Only annoyance is that it turns your volume all the way up. Would be nice if on leaving the app, it reset your volume to what it was previously.

I love it... This is just what i was looking for

So So The sine wave is semi accurate, plenty good for audio testing. But, the levels are not accurate. When hooked up to an oscope on my s3, -10db 1 khz signal only produced 150 mV pk when it should be 447 mV pk. This will undoubtedly differ with different phones, but an actual db reading shouldnt be used if it isnt accurate.

Doesn't work as described! Sound still stops when screen turned off. White noise has VERY noticeable "beat" indicating looping. Poor

eh. I really liked this, at first & I still do, but I end up going back to "audio test tone generator" because of it's ability to make really fine adjustments...

Runs well on Xperia X10 with Android 2.1. It's just not that useful to me.
