The WAV Trigger is an audio development platform that allows you to easily add music and sound effects to your project. Tracks can be controlled via 16 trigger inputs, or by using a native serial control protocol. Tracks are stored on a micro-SD card. Trigger inputs can be connected directly to switches and buttons, or to digital outputs from sensors or another microcontroller.
The WAV Trigger plays uncompressed WAV files up to 16-bit stereo 44.1kHz, the same quality as audio CD’s. One significant feature is that the board has the ability to play multiple tracks at the same time.
