This implements a DSRC (Drift-compensating adaptive Sample Rate Converter) for use with the UAOL feedback feature to perform audio resampling and compensate for small dynamic drift. The implementation employs linear interpolation. Signed-off-by: Serhiy Katsyuba <serhiy.katsyuba@intel.com>
This adds unit tests for DSRC using Zephyr's ztest framework. Signed-off-by: Serhiy Katsyuba <serhiy.katsyuba@intel.com>
This extends UAOL functionality to support audio rate adjustment based on the "desired" clock reported by the USB playback device via the USB feedback endpoint. The firmware calculates drift from this feedback and instructs UAOL hardware to increase or decrease the transfer rate accordingly. A DSRC (Drift-compensating adaptive Sample Rate Converter) is used when necessary to perform audio resampling and compensate for small dynamic drift.
