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 30
Ω 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
