Detailed Description

This structure defines the codec 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 http://tiexpressdsp.com/index.php?title=Extending_data_structures_in_xDM for more details.

Field Documentation

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

Input frame size in bytes for sample based codecs.

Rate selection for multi_rate codecs

Mode selection for multi_mode codecs

VAD_On =1, VAD_OFF = 0

0 - OFF, 1 = NS-A, 2 = NS-B etc

0 = TTY OFF, 1 = 45.45bauds 2 = 50 bauds

0 = DTMF_OFF, 1 = DTMF_ON

1 = ON, 0 = OFF

0 - DISABLED; 1 - ENABLED
