* 8-Bit PWM output- no external DAC required* 62.500 kHz (Fullratefullrate) / 31.250 kHz (Halfratehalfrate) sampling rate @ 16 MHz * 31.250 kHz (Fullratefullrate) / 15.625 kHz (Halfratehalfrate) sampling rate @ 8 Mhz * Mono, bridge and stereo mode

* integrated 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

== Background Restrictions ==* Audio file must be converted prior use * Audio files must reside in root directory of card* File name of audio file must be in 8.3-format* Audio file must reside completely non-fragmented on card* fullrate and stereo actually leads to buffer underruns == Quickstart guide ==* Install library: Unzip all to your /libraries/ folder.* Copy file /libraries/SimpleSDAudio/examples/example.raw to root folder of a freshly formated SD card (don't use quick format!)* Connect SD card to your Arduino board (using shield or whatever, SD card's chip select should go to pin 4, all other to SPI pins)* Connect a speaker, headphone or line-in via 100 ohm resistor in series to audio output pin (pin 9 on Arduinos with ATmega168/328, pin 44 on Arduinos with ATmega1280/2560). Connect other end of speaker/ground of line-in to GND* Launch Arduino IDE and try example "BareMinimumWithDebug" first* You should hear some audio. Activate serial monitor to find some information if it does not work. Maybe you have to adjust SD cards CS pin in sketch. == Software installation guide ==   == Preparation of SD card and conversion of audio files == == Hardware setup ==
