SYNOPSIS¶
Macros¶
#define OPUS_AUTO
Auto/default setting. #define OPUS_BITRATE_MAX
Maximum bitrate. #define OPUS_APPLICATION_VOIP
Best for most VoIP/videoconference applications where listening quality and
intelligibility matter most. #define OPUS_APPLICATION_AUDIO
Best for broadcast/high-fidelity application where the decoded audio should be
as close as possible to the input. #define
