Specification

Support multiple formats of decoding: MP3/WMA/AAC/WAV/Ogg Vorbis/MIDI
Can real-time imitate as much as 128 kinds of MIDI instruments.
- Universal MIDI and file 0 in SP‐MIDI format can be played, and files in format 1 and 2 must be transformed into format 0 by the users.
- Number of polyphony is 64 at most, and the number of polyphony that can continue at most is 40.

Integrate 2.2w stereo amplifier（LM4863）
- Can control the enable through the GPIO4 of VS1053.
With 2.5mm stereo earphone interface onboard.
Earphone/extroverted automatic switchover function.
18-bit oversampling, multi-bit, sigma‐delta type high-precision DAC
- Oversampling generally refers to higher sampling rate several times than the nominal sampling rate, and it is commonly used to improve the sampling accuracy. It means when restore the digital sound, use sampling rate several times higher than the nominal sampling rate to output, which can make the abrupt of the ladder of the audio flatten out, to lower the digital background noise and reduce the distortion, thereby get high-quality audio surpassing the effect of the original sampling rate outputting.
