Sound Trigger

Offers in-app purchases

Sound Trigger allows you to play audio clips, such as sound effects and background music. It designed to be used for theater or live music, where there is a collection of audio clips that need to be triggered during the performance.

To create a trigger, choose an audio file that is stored on your phone or tablet. The trigger is shown on the main screen with a large button that starts and stops playback. Each trigger has the following properties:

* Output level
* Fade in time
* Fade out time
* Pause playback or stop and reset to the beginning
* Custom label

Multiple clips can be played at the same time. There's also a button that stops playback of all triggers, in case of emergency.

The free version of Sound Trigger supports up to four triggers. To remove this limit, choose the "Upgrade" item in the options menu and buy the "Unlimited triggers" option for $2.

Note that currently the only supported file format is uncompressed WAV.

Sound Trigger is developed in the spirit of openness and transparency. I encourage users to get involved in the design of new features, testing, and localization. I have set up a Bitbucket site where users can see and update bugs and enhancement requests:

If you encounter bugs or have feature requests, please check Bitbucket and see if it's already a known issue. If the issue hasn't been reported, please file it in Bitbucket or contact me directly instead of leaving a bad review on Google Play. I will do my best to quickly respond to user issues.

Thanks for your interest in Sound Trigger! I hope you have as much fun using it as I did developing it.
