Robertsonics designs high performance embedded audio players and processors, used worldwide by professionals and hobbyists alike.

  • WAV Trigger

    WAV Trigger

    For professional and demanding applications. The worlds least expensive truly polyphonic embedded audio player – allowing you to play and layer up to 14 CD quality (16-bit, 44.1kHz, stereo) tracks independently. Additional trigger modes and settings provide pause and resume capability, specify track ranges for stop, random and sequential play. Trigger inputs support passive (contact closure) or active (3.3V / 5.0V logic) as well as inverted modes on an individual basis. MIDI serial option provides velocity-sensitive triggering of up to 2048 tracks. Stereo line-level output, on-board 2W mono amplifier and speaker connector for true single-board operation. Low-power sleep mode for battery operation. Firmware upgradable.

    MP3 Trigger

    Keep things simple. 18 trigger inputs connect to your contact closures to fire specific MP3 Tracks (up to 192kbps stereo) on a microSD card, or to implement transport functions like next, previous, stop, random play, volume etc. Simple, ASCII-based serial protocol makes it easy to control from an Arduino. Text init file allows setting the serial baud rate and alternate trigger functions. Special trigger modes allow simple logic without the need for an external microcontroller. Firmware upgradable.

  • Tsunami

    NEW! Tsunami

    All the same features as the WAV Trigger but with four stereo outputs (8 audio output channels), plus more voices, seamless looping and a dedicated MIDI input with integrated opto-isolator. Possibly the first embedded audio player capable of playing 5.1 or 7.1 surround sound with a single trigger input. Available now from SparkFun.

    Carina is the only Blackfin development board designed from the ground up for audio. Everything you need for a professional stereo effects processor. Sporting a 400MHz Blackfin, 256MB of external SDRAM, balanced stereo inputs and outputs, 24-bit ADC/DAC >98dB SNR, and sample rates up to 96KHz. A 26-pin IDC connector provides plenty of general purpose I/O for user interface controls. A “plug-in” style software framework for VisualDSP lets you immediately focus on algorithm development.

In an ongoing attempt to be more efficient, I took a break from working on Tsunami and WAV Trigger firmware to develop a new Unified Init File Maker utility that works with both products.

In addition to looking a bit more up-to-date, it improves upon the previous individual apps in a number of ways:

  • One app will work with WAV Trigger and both mono and stereo versions of the Tsunami.
  • Offers online help with tooltips.
  • Provides live updates and remote control when used with a suitable USB-to-serial adaptor.

A beta version is now available and I encourage you to use it. The Windows and OS X versions are posted on the download pages of both products. Please use this post to provide any issues or feedback.

Note: If you use the new app to open previously saved init files, it will always open them as WAV Trigger files. You’ll need to start new Tsunami files (mono or stereo) from scratch.

A note about the linux version:

After doing some research into distributing Linux executables, I’ve come to the conclusion that it’s not practical to provide a ready-to-run Linux app that will run on all distros and machines. For those of you who want to run this utility on Linux, it’s not that hard, but you do have to download JUCE, install some dev packages, and then run make on the source project. I’ve included a link to the project’s source github repo on the download pages. When I get time, I’ll write up a step-by-step guide on how to do this (at least for Ubuntu) and include it in the repo’s readme.
