About this app

You can test the audio devices connected to your smartphone.

- Stereo Test : You can test the left and right sound of a stereo audio device.

- Delay Test : You can test the audio delay. Check the time difference between when the white ball passes 0 milliseconds and when the tick sound actually sounds on the audio device. Usually, wireless connections such as Bluetooth have longer delay than wired connections.

- Frequency Test : You can test the frequency range of your audio device.
※CAUTION : Testing at high volumes can hurt your ears. Turn the volume down and do a frequency test.

I hope this app is useful to you.
Thank you.

Ratings and reviews

Works well, can check all my speakers are in phase and make sure my time alignment settings in the car are correct. Really simple to use as well. Definitely one of the better apps about. Only draw back is not being able to get rid of the adds, but since they are only at the bottom of the screen don't really distract from performing the tests that the app is designed for.

Does what it says exactly. Just what I wanted. Now I want to find songs that have good stereo effects & soundstage, to really test them, musically. 1 star dropped because the frequency test controls are a little fiddly on a phone. Could do with steps of 100/1000, or if you press & hold +-10, it could repeat, rather than having to repress 100 times, to advance 1000. Slider is just as fiddly. Minor quibble really.

This is a great app. It does everything it is designed and advertised to do. Although it would be nice if there was a forum where people could share their results with tws earbuds or just make some sort of chart for pre-purchase comparison. It would be great for the community. Moreover it would be nice if the app could show what audio codec was being used whilst testing.
