Home / Development / Sound / Modules / Sparkfun WAV Trigger Sparkfun WAV Trigger SKU: 50751 Sparkfun WAV Trigger$62.69 USD This is easily the best and most complete audio playback module for hardware hacking we’ve seen. 16 trigger lines, 14 simultaneous playbacks – it’s impressive.Out of stock SKU: 50751 Categories: Development, Modules, Sound Tag: allAccounts Description Resources More Info Reviews (0) Description When starting to review this audio replay unit, I didn’t expect much. Often, they’re simple, with low performance, and pretty barebones. But a closer look at this unit by ex-Disney Imagineer Jamie Robertson shows that it’s really well thought out. Mr. Robertson needed a player with flexibility and lots flexibility, so he worked Sparkfun modules into something… close. With the WAV trigger, he’s pulled together a very impressive module that should easily satisfy most hacker sound projects. The WAV Trigger uses 16-bit, 44.1kHz uncompressed WAV files – the same specification as audio CD files. It’s combined with 16 trigger input lines and 14-channel simultaneous playback, so you can easily create a 2-octave playback instrument with impressively clean sound. Pipe the output through either a 1/8″ headphone line-level jack or the amplified mono speaker output. Had other thoughts on how to control it? It includes both a serial interface line and MIDI port. This unit can create some impressive effects, as you can start multiple tracks at the same time, fade-in, fade-out, and cross-fade between tracks. Some playback units are pretty stringent on naming conventions and how to structure the files on the SD card. The WAV Trigger also uses an SD card but manages the configurations through an ASCII INI file stored with the media files. Usually, an INI file means hand-editing, but Mr. Robertson has also created a management tool that makes configuring the WAV Trigger very straightforward.
