Product Launch!
I'm very pleased to announce that, after a lot of hard work, the WAV Trigger goes live on the SparkFun site tomorrow. I'm excited because I think this is a unique product that'll hopefully inspire a lot of cool ideas.
Please bear with us as we iron out the documentation and details. The most up-to-date and accurate info will be found here for the time being, simply because I can update things myself, without having to go through proper "channels".
The firmware shipping with the units from SparkFun is pretty much complete, although I do plan to add features and enhancements in the near future. Unlike the MP3 Trigger, the WAV Trigger's firmware update process uses the serial control port, which happens to be pin-compatible with the FTDI Basic 5V. If you plan to take advantage of upcoming firmware releases, I suggest you get one of these handy devices.
Some things I plan to do:
WAV file compatibility: At the moment, the WAV Trigger supports only 16-bit, stereo, 44.1kHz WAV files with no meta-data. These are easy to create using a sound editor such as Audacity, so it's not a big deal. But I do plan to support at least 22.05kHz sample rate in the future - although it will be a global setting - no mixing of sample rates. I also plan to make it more forgiving with respect to there being non-audio (meta) data in the file.
Signal Processing & Effects: The CPU is, after all, a DSP. I plan to add a 3-band EQ to the output stage, with settings from the init file. I'd also like to see if I could manage a nice reverb algorithm with the available RAM.
MIDI functionality: It's pretty cool already, being able to map an entire keyboard range of notes to stereo WAV files, but it would be even cooler to use MIDI Control Change messages, or even a trigger input, to map to an entirely different set of sounds. Right now, you can do this by changing the MIDI Channel number on your controller, but not having to change channels would be even easier.
Serial control: The WAV Trigger's serial control protocol is already more sophisticated than the MP3 Trigger's simple protocol, with the ability to control individual track transport functions and volumes. I plan to add things like the ability to export track filenames. Significantly, I also plan to develop and publish an Arduino WAV Trigger Control Library to simplify using the serial control features for those of you in the Arduino world.
