TRAXMOD

Lossless Digital Audio Player

TRAXMOD is a lossless, portable digital audio player using the Microchip PIC32 high speed microcontroller chip. Currently, TRAXMOD-PIC32 can play FLAC wave audio (and other formats) streaming off of a FAT formatted MMC/SD Card at 44100Hz, 16 bits, stereo using a Burr-Brown PCM1770 DAC with integrated headphone amp. TRAXMOD v2.0 features dynamic voltage level scaling, DMA, and other power saving techniques to provide extremely long battery life. A single AA high capacity NiMH/NiZn battery can make it through an entire 5 day work week between charges (depending on memory card efficiency).
