AudioEncodeCodecSettings type
The part of AudioEncodeSettings that ties the codec to the channel layouts and bitrates it can do.
-
channelLayout: the channel layout of this encode. If the source’s doesn’t match it will be automatically converted; to gain greater control over this process, see NorskTransform.audioMix() and NorskTransform.audioMixMatrix() -bitrate: the target bitrate of this encode, in bits per second -codec: what codec to (re) encode the audio to
MP3 is mono or stereo only, and its bitrate must be one that its sample rate allows (see Mp3Mpeg1Bitrate, Mp3Mpeg2Bitrate, Mp3Mpeg25Bitrate) - other values are rejected by the server too. MP2 is the same, except that at 32 / 44.1 / 48 kHz its bitrate also depends on the channel layout (see Mp2Settings).
