Adafruit "Music Maker" Arduino MP3 Shield for with 3W Stereo Amp All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why we spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega. This version of the shield includes an onboard 3W/channel stereo audio amplifier that can drive 4 or 8 ohm speakers. It's the same amplifier as in our TS2012 breakout, a great class D amplifier that sounds good and is power-conscious for portable/battery usage. Volume control is handled by the VS1053 chip. Each order comes with one fully-assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and 2x3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. Speakers, $1 headphones, SD card and Arduino not included! Specifications: Features the VS1053B codec chip - decodes Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, MIDI. Encodes Ogg or WAV/PCM Stereo audio out with proper audio filter caps and ground reference so it can be safely

Light-weight SPI interface so that any Arduino can play audio from an SD card. Play with the audio by adjusting bass, treble, and volume digitally. Use to record audio in both PCM (WAV) and compressed Ogg Vorbis. Features the VS1053, an encoding/decoding chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV.
