Play audio files with your Arduino in decent quality from SD card, only very few additional hardware required.
Features
- 8-Bit PWM output - no external DAC required
- 16-Bit emulation using 2x 8-Bit PWM output - requires only two resistors
- 62.500 kHz (fullrate) / 31.250 kHz (halfrate) sampling rate @ 16 MHz
- 31.250 kHz (fullrate) / 15.625 kHz (halfrate) sampling rate @ 8 Mhz
- PWM output is operating always at fullrate for easier filtering
- Mono, bridge and stereo mode
- RAM usage ~1.3 kByte
- ROM usage ~6.1 kByte
- Integrated SD library (minimal FAT only, optimized for low RAM usage and high performance)
- Works with most SD card shields that are hooked to SPI port
- Easy to use API: 1. init library, 2. select audio file, 3. call play
- Supports SD and SDHC cards formated with FAT16 or FAT32
