modifiedSBC (mSBC)
Capable of voice processing with WBS (WideBandSpeech): Fx=16kHz by supporting the mSBC
encode/decode function
[ Audio processing functions ]
<Audio data digital processing block>
Equalizer function
Supports max of 20-band (stereo 1ch) and unused band can be used for not only the voice output but also
used for other processing
Supports signal processing for subwoofer
Sampling conversion (Fs=32/44.1/48kHz) when playing compressed audio, High band extended
processing supported
Mute (/12dB), attenuator
De-emphasis filter
Embedded level/peak hold circuit and can hold up to 8 data
Noise cancel/Echo cancel function
Supports noise cancel/echo cancel at Fs=8kHz
Supports input/output of Fs=16kHz voice data
<Audio input processing block>
Analog Audio data input (3-channels by stereo)
Single Ended input
: 2 channels
Differential input
: 1 channel
Input Gain
: 12.5dB to +18.5dB (1dB step)
24bit accuracy AD converter
Digital audio input (Stereo input: Max of 3 channels)
Supports digital 3-line (LR clock, bit clock, audio data) connection and clock can be master or slave
Data format supports IIS/MSB first right justified and etc.
Input data can support 8kHz to 96kHz, and by sampling conversion, converts to the suitable Fs
(Playback Fs=32/44.1/48kHz etc.)
