GetAudioFrameCount

Gets count of frames executed.

Synopsis

uint16 GetAudioFrameCount (void)

Description

Gets 16-bit value that is incremented on every sample frame, typically at 44100Hz. This is only useful for determining relative elapsed frame counts.

It can be used as a measure of audio time more precise than GetAudioTime().

Arguments

None

Return Value

16-bit sample frame count.

Implementation

SWI implemented in Audio folio V24.

Example

Example 1: GetAudioFrameCount example

NewFrameCount = GetAudioFrameCount();
ElapsedFrames = (NewFrameCount - OldFrameCount) & OxFFFF;
OldFrameCount = NewFrameCount;

Caveats

GetAudioFrameCount() must be called at least once every 65536 (i.e. 2**16) sample frames to avoid wrap around of the 16-bit value. Call at least every second to be safe.
