Detailed Description

This structure defines the algorithm parameters that can be modified after creation via control() calls.

Remarks:
It is not necessary that given implementation support all dynamic parameters to be configurable at run time. If a particular algorithm does not support run-time updates to a parameter that the application is attempting to change at runtime, it may indicate this as an error.
This structure may be extended by individual codec implementations allowing customization with vendor specific parameters. The presence of vendor specific extensions will be detected by the value of the size parameter.
The size field must be correctly set by the caller. See https://processors.wiki.ti.com/index.php/Extending_data_structures_in_XDM for more details.

Field Documentation

XDAS_Int32 IAUDENC_DynamicParams::size

Size of this structure in bytes. Because this structure can be extended, this field must be correctly set by the caller.

XDAS_Int32 IAUDENC_DynamicParams::inputFormat

The input PCM format. See IAUDIO_PcmFormat.

XDAS_Int32 IAUDENC_DynamicParams::bitRate

Average bit rate, in bits per second.

XDAS_Int32 IAUDENC_DynamicParams::sampleRate

Sampling frequency in Hz. For example, if the sampling frequency is 44.1 kHz, this field will be 44100.

XDAS_Int32 IAUDENC_DynamicParams::numChannels

Number of Channels. See IAUDIO_ChannelId.

XDAS_Int32 IAUDENC_DynamicParams::numLFEChannels

Number of LFE (Low Frequency Effects) channels in the stream.

XDAS_Int32 IAUDENC_DynamicParams::inputBitsPerSample

Number of input bits per output sample. For example, if there are 16 bits per PCM input sample, this should be set to 16.
