Combined AV Headset Application
Step 2: Building the MP3 decoder
Build the MP3 decoder application by opening the mp3_decode workspace and selecting build in xIDE. The mp3_decode workspace can be built in exactly the same way as the sbc_decode workspace in section 5.1 Step 4.
Once the mp3_decode application has been built go back to section 5.1 step 3 and continue with building the av_headset_hfp application.
5.3CVC echo cancellation and noise reduction software
To include CVC (Clear Voice Capture) echo cancellation and noise reduction simply add the define symbol INCLUDE_CVC to the Project Properties / Define symbols field before building the av_headset_hfp.xiw project.
Note: The CVC software is supplied for demonstration purposes only, is time limited and will become inactive after processing data for five minutes.
The ParamMgr Utility can be used to fine tune the CVC code to optimise the performance based on the acoustic characteristics of your product. Please see the ParamMgr User guide (CSR reference
