Detailed Description

struct snd_codec : Identifies the supported audio encoder/decoder. See SND_AUDIOCODEC macros. : Number of input audio channels : Number of output channels. In case of contradiction between this field and the channelMode field, the channelMode field overrides. : Audio sample rate of input data : Bitrate of encoded data. May be ignored by decoders : Encoding rate control. See SND_RATECONTROLMODE defines. Encoders may rely on profiles for quality levels. May be ignored by decoders. : Mandatory for encoders, can be mandatory for specific decoders as well. See SND_AUDIOPROFILE defines. : Supported level (Only used by WMA at the moment) : Channel mode for encoder. See SND_AUDIOCHANMODE defines : Format of encoded bistream. Mandatory when defined. See SND_AUDIOSTREAMFORMAT defines. : Block alignment in bytes of an audio sample. Only required for PCM or IEC formats. : encoder-specific settings : reserved for future use
