Audio format details


#include <aoi.h>

typedef struct AOAudioFormat_t;


The AOAudioFormat_t structure is a private data type that describes an audio format. The structure contains at least the following members:
uint32_t channels
The number of audio channels. For example, a stereo signal has 2 channels.
uint32_t depth
The audio depth (sample rate), in bytes per second.
int32_t frame_rate
The frame rate (frequency), in frames per second. This value may be divided by scale to represent a floating-point frame rate.
int32_t scale
A scaling variable to convert frame_rate into an actual rate. For example: 2997/100=29.97.
int32_t duration
The duration of the audio, in frames.
