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