ISPHENC_DynamicParams Struct Reference
[XDM ISPHENC Speech/Voice Encoder Interface]

#include <isphenc.h>

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.

Field Documentation

XDAS_Int32 ISPHENC_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 ISPHENC_DynamicParams::frameSize

Input frame size in bytes for sample based codecs.

XDAS_Int32 ISPHENC_DynamicParams::bitRate

Rate selection for multi_rate codecs

XDAS_Int32 ISPHENC_DynamicParams::mode

Mode selection for multi_mode codecs

XDAS_Int32 ISPHENC_DynamicParams::vadFlag

VAD_On =1, VAD_OFF = 0

XDAS_Int32 ISPHENC_DynamicParams::noiseSuppressionMode

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

XDAS_Int32 ISPHENC_DynamicParams::ttyTddMode

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

XDAS_Int32 ISPHENC_DynamicParams::dtmfMode

0 = DTMF_OFF, 1 = DTMF_ON

XDAS_Int32 ISPHENC_DynamicParams::dataTransmit

1 = ON, 0 = OFF

XDAS_Int32 ISPHENC_DynamicParams::homingMode

0 - DISABLED; 1 - ENABLED
