Constants

This section describes all constants used in MIDAS sample playback. They are grouped according to the enum used to define them.

 

4.1.1 MIDASsampleTypes

 

enum MIDASsampleTypes

Description

These constants identify different sample types. They are used with the functions MIDASloadRawSample, MIDASplayStreamFile and MIDASplayStreamPolling to indicate the format of the sample data. The byte order of the sample data is always the system native order (little endian for Intel x86 systems).

Values

MIDAS_SAMPLE_8BIT_MONO

8-bit mono sample, unsigned

MIDAS_SAMPLE_8BIT_STEREO

8-bit stereo sample, unsigned

MIDAS_SAMPLE_16BIT_MONO

16-bit mono sample, signed

MIDAS_SAMPLE_16BIT_STEREO

16-bit stereo sample, signed

 

4.1.2 MIDASloop

 

enum MIDASloop

Description

These constants are used to indicate the loop type of a sample or stream.

Values

MIDAS_LOOP_NO

Sample or stream does not loop

MIDAS_LOOP_YES

Sample or stream loops

 

4.1.3 MIDASpanning

 

enum MIDASpanning

Description

These constants are used to describe the panning position of a sound. Legal panning positions range from -64 (extreme left) to 64 (extreme right), inclusive, plus MIDAS_PAN_SURROUND for surround sound.

Values

MIDAS_PAN_LEFT

Panning position full left

MIDAS_PAN_MIDDLE

Panning position middle

MIDAS_PAN_RIGHT

Panning position full right

MIDAS_PAN_SURROUND

Surround sound

 

4.1.4 MIDASchannels

 

enum MIDASchannels

Description

These constants are used to indicate the channel number a sound should be played on. Legal channel numbers range from 0 upwards, depending on the number of open channels. In addition, MIDAS_CHANNEL_AUTO can be used with MIDASplaySample.

Values

MIDAS_CHANNEL_AUTO

Select channel automatically, used with MIDASplaySample
