Comments on Signal Generator for Android

★★★★★ A Google User · Nov 11, 2013

Great for quick tests. I ran some very quick oscilloscope tests, and it can provide a sine wave 20-20kHz, accurate to 2SF, the third SF is ±1 of the true value. Do not use this app when charging. If you do, there will be a rather lovely 50Hz signal overlaid on the output. At higher frequencies it's not an issue, but at lower frequencies the interference is very noticeable, and at an output ~50Hz produces a lovely beat frequency. Remember that your android device is not designed as a signal generator, therefore the output is not going to be as clean and perfect as a real signal generator. Different devices may produce different results. I recommend you test yours with an oscilloscope where possible.

Hmm mm... I was looking for a lightweight Pink Noise generator... downloaded several to try, and WISH this one won. It has a clean, simple interface, great adjustability, and seems stable. If it played in the background, and appeared in the notification bar, it would be IDEAL. It's a great app for testing speakers, but that's about the only application I can think of...

Great, free signal generator. Very limited functionality but as a simple single tone generator combined with white and pink noise for audio system testing - it's great value for what you pay for it - ie nothing.

Poor low freq access range These graphs leave little wiggle room for low freq ones. Maybe only 1/10th of the slider scroll is dedicated here. Above 2khz, is okay. Below it, u have to type the desired freq, if u likt to play below 2khz,a lot, u will have a devil pf time tweaking as there is little scroll range dedicated here, go elsewhere

Doesn't keep playing when minimized Unlike a normal audio player (and some of your competitors), the sound stops when another app is opened. So you cannot use the phone to do anything else, such as to control the equipment you are testing.

Fair to poor. Very frustrating this app will turn your volume all the way up can blow speakers be careful. Also needs ability to run in the background.
