Macro Definition Documentation

BIGVOICE_AUDIO_INPUT_COUNT

#define BIGVOICE_AUDIO_INPUT_COUNT   1

This version number of inputs for this process.

Deprecated:

For binary compatibility, this should be runtime checked to be the same as bigvoice_GetAudioInputCount()

Definition at line 58 of file sound4.bigvoice.cl.h.

BIGVOICE_AUDIO_OUTPUT_COUNT

#define BIGVOICE_AUDIO_OUTPUT_COUNT   1

This version number of outputs for this process.

Deprecated:

For binary compatibility, this should be runtime checked to be the same as bigvoice_GetAudioOutputCount()

Definition at line 64 of file sound4.bigvoice.cl.h.

BIGVOICE_AUDIOFRAME_COUNT

#define BIGVOICE_AUDIOFRAME_COUNT   12

This version number of frames in a process chunk.

Deprecated:

For binary compatibility, this should be runtime checked to be the same as bigvoice_GetChunkSizeInFrames()

Definition at line 46 of file sound4.bigvoice.cl.h.

BIGVOICE_CHANNEL_COUNT

#define BIGVOICE_CHANNEL_COUNT   1

This version number of channels.

Deprecated:

For binary compatibility, this should be runtime checked to be the same as bigvoice_GetChannelCount()

Definition at line 52 of file sound4.bigvoice.cl.h.

BIGVOICE_SAMPLE_RATE

#define BIGVOICE_SAMPLE_RATE   48000

This input/output sample-rate.

Deprecated:

For binary compatibility, this should be runtime checked to be the same as bigvoice_GetSampleRate()

Definition at line 70 of file sound4.bigvoice.cl.h.

Typedef Documentation

bigvoice_loggerfn

typedef void(* bigvoice_loggerfn) (enum bigvoice_LogSeverity, const char *)

Do not block/wait in the callback, it can be called from any place in code

Note

In all library, all char* are UTF-8 encoded

Definition at line 185 of file sound4.bigvoice.cl.h.

Function Documentation

bigvoice_GetAudioInputCount()

unsigned int bigvoice_GetAudioInputCount

(

)

Get the number of inputs for this process

Remarks

All inputs have bigvoice_GetChannelCount() channels

Fixed to 1, but should be checked for backward compatibility

Returns

The process input count

bigvoice_GetAudioOutputCount()

unsigned int bigvoice_GetAudioOutputCount

(

)

Get the number of outputs for this process

Remarks

All outputs have bigvoice_GetChannelCount() channels

Fixed to 1, but should be checked for backward compatibility

Returns

The process outputs count

bigvoice_GetChannelCount()

unsigned int bigvoice_GetChannelCount

(

)

Get the number of channels needed by this process

Remarks

Fixed to 1, but should be checked for backward compatibility

Returns

The process channels count

bigvoice_GetChunkSizeInFrames()

unsigned int bigvoice_GetChunkSizeInFrames

(

)

Get the default number of frames in a process chunk.

The output will be available only by chunks of this size.

Note

A Frame is a set of bigvoice_GetChannelCount samples

Remarks

Fixed to 12, but should be checked for backward compatibility

Returns

The process chunk size in frame

Deprecated:

Use bigvoice_GetPossibleChunkSizeInFrames

bigvoice_GetPossibleChunkSizeInFrames()

unsigned int * bigvoice_GetPossibleChunkSizeInFrames

(

)

Get the possibles number of frames in a process chunk.

The output will be available only by chunks of this size.

Note

A Frame is a set of bigvoice_GetChannelCount samples

Returns

An array of possible process chunk size in frame, ending with 0

bigvoice_GetSampleRate()

unsigned int bigvoice_GetSampleRate

(

)

Get the processing sample-rate

Remarks

For now, always return 48000, but should be checked for backward compatibility

Returns

The process sample-rate in Hz

bigvoice_GetVersion()

const char * bigvoice_GetVersion

(

)

Get the process version string

Returns

version string

bigvoice_SetLoggerCallback()

void bigvoice_SetLoggerCallback

(

bigvoice_loggerfn

logger

)

Set a callback for logging

If not set, a default logger prints to stderr.

Warning

Do not block/wait in the callback, it can be called from any place in code

Parameters

logger

A C callback called for logging.

bigvoice_SetLogSeverity()

void bigvoice_SetLogSeverity

(

enum bigvoice_LogSeverity

severity

)

Change the global log severity

Logs above this level will not be printed.

Parameters

severity

Log severity

SOUND4_GetProcessInfo()

const struct SOUND4_ProcessInfo * SOUND4_GetProcessInfo

(

)

Get this processor description

Common to all SOUND4 processors.

Returns

the process description
