Attempt to use newer version failed due to the following reasons:
|
|
|
|
|
|
|
|
|
|
- Audio artifacts with high frequency sine waves is still present.
|
|
|
|
|
- PLC seems not to work better than the old version (maybe the integration in llcon
|
|
|
|
|
was not correct and caused the behaviour).
|
|
|
|
|
- No bit stream compatibility to the old version of CELT previously used in llcon.

INTEGRATION in the llcon software:
|
|
|
|
|
- celt_mode_create: The number of channels parameter must be removed
|
|
|
|
|
- celt_encoder_create -> celt_encoder_create_custom with additional parameter number of channels
|
|
|
|
|
- celt_decode: Additional parameter: frame size (always SYSTEM_FRAME_SIZE_SAMPLES for llcon)
|
|
|
|
|
- celt_encode: The NULL parmeter must be replaced by the frame size (always SYSTEM_FRAME_SIZE_SAMPLES for llcon)
|
|
|
|
|
- CUSTOM_MODES preprocessor macro must be defined
