6. Sound-related peripherals
mikromedia 3 features powerful VS1053B IC. It is an Ogg
Vorbis/MP3/AAC/WMA/FLAC/WAV/MIDI audio decoder, and
a PCM/IMA ADPCM/Ogg Vorbis encoder, both on a single
chip. It features a powerful DSP core, high-quality A/D and
D/A converters, stereo headphones driver capable of driving
a 30Ω load, zero-cross detection with the smooth volume
change, bass and treble controls, and much more.
6.1 Audio CODEC
Resource-demanding and complex audio processing tasks can be
offloaded from the host MCU by utilizing a dedicated audio CODEC IC,
labeled as VS1053B (1). This IC supports many different audio formats,
commonly found on various digital audio devices. It can encode and
decode audio streams independently while performing DSP-related tasks
in parallel. The VS1053B has several key features that make this IC very
popular choice when it comes to audio processing.
By offering high-quality hardware compression (encoding), the VS1053B
allows the audio to be recorded taking up much less space compared to
