AuDataFormats(3) Library Functions Manual AuDataFormats(3)Name
AuDataFormats - audio data formats.
Synopsis
#include <audio/audiolib.h>
Currently, the following data formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8, AuFormatLinearSigned8, AuFormatLinear-
Signed16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUnsigned16LSB.
AuFormatULAW8
Designates a data format in which samples are stored as 8-bit ulaw values.
AuFormatLinearUnsigned8
Designates a data format in which samples are stored as unsigned 8-bit values.
AuFormatLinearSigned8
Designates a data format in which samples are stored as signed 8-bit values.
AuFormatLinearSigned16MSB
Designates a data format in which samples are stored as signed 16-bit values, with the most significant byte first.
AuFormatLinearUnsigned16MSB
Designates a data format in which samples are stored as unsigned 16-bit values, with the most significant byte first.
AuFormatSignedLinear16LSB
Designates a data format which samples are stored as signed 16-bit values, with the least significant byte first.
AuFormatLinearUnsigned16LSB
Designates a data format which samples are stored as unsigned 16-bit values, with the least significant byte first.

AuMakeElementImportClient(3) Library Functions Manual AuMakeElementImportClient(3)Name
AuMakeElementImportClient - initialize an ImportClient element
Synopsis
#include <audio/audiolib.h>
AuMakeElementImportClient(element, sample_rate, format, num_tracks, discard, max_samples, low_water_mark, num_actions, actions)
AuElement *element; /* RETURN */
unsigned short sample_rate;
unsigned char format;
unsigned char num_tracks;
unsigned char discard;
AuUint32 max_samples;
AuUint32 low_water_mark;
int num_actions;
AuElementAction *actions;
Arguments
element Returns the initialized element.
sample_rate
Specifies the sample rate of the audio data.
format Specifies the format of the audio data. Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8,
AuFormatLinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUn-
signed16LSB.
num_tracks
Specifies the number of tracks in the audio data.
discard Specifies if the import should be paused initally. Normally AuTrue. AuFalse may crash the server.
max_samples
Specifies the maximum number of samples to accept in a single read. Ignored for "trivial" flows.
low_water_mark
Specifies when to request additional audio data from the client application. When this number of samples are left in the buffer,
and an EOF hasn't been received, a NotifyEvent with kind set to AuElementNotifyKindLowWater will be sent to the client applica-
tion.
num_actions
Specifies the number of actions in actions.
actions Specifies the list of actions to associate with this element. Entries in this list can be initialized with AuMakeChangeStateAc-
tion, AuMakeSendNotifyAction, and AuMakeNoopAction. May be NULL.
Description
AuMakeElementImportClient sets the type of element to AuElementTypeImportClient and initializes the importclient member of element with the
remaining arguments.
AuMakeElementImportClient is implemented as a macro.
