Microduino AudioPro is a multi-function audio module with VS1053 as the decoder, and it integrates 2.2W stereo amplifier, and supports 2.5mm stereo headphone interface and MIDI function. This module is usually used with the mCookie SD module to play music files.
Support multiple formats of decoding：MP3/WMA/AAC/WAV/Ogg Vorbis/MIDI;
Can real-time simulate as many as 128 kinds of MIDI instruments;
The open-source hardware circuit design and compatible-with-Arduino programming development environment;
The unified Microduino interface specification and abundant peripheral modules, which make it can be extended and connected with other modules and sensors which meet Microduino interface specification, quickly, conveniently and flexibly;
2.54-spacing mother line interface is convenient for integrating to the hole plate.
Support multiple formats of decoding: MP3/WMA/AAC/WAV/Ogg Vorbis/MIDI;
Can real-time simulate as many as 128 kinds of MIDI instruments:
The universal MIDI and SP‐MIDI format 0 file can be played, and the format 1 and 2 file must be changed into format 0 by the players;
The number of polyphony is 64 at most, and the number of continuous polyphony is 40 at most.
Integrate 2.2w stereo amplifier（LM4863）:
Can control enabled through the GPIO4 of VS1053.
2.5mm stereo headphone interface onboard;
Head/extrovert automatically switching function;
18-bit-oversampling, multi-bit, and sigma‐delta high-precision DAC:
Oversampling generally refers to the higher sampling rate more than nominal sampling rate for integral number of times, which is commonly used to improve the sampling accuracy. It means when restore the digital voice, use the sampling rate several times more than the nominal sampling rate to output, which can make the steps of the audio steep gently, and low the digital background noise and reduce the distortion, thereby get the high-quality audio superior to the output effect of the original sampling rate.
