BASS.NET API for the Un4seen BASS Audio Library

WaveFormGetCuePoints Method (Int64, Int64, Double, Double)

BASS.NET API for the Un4seen BASS Audio Library
Determines silence positions at the beginning and end of a rendered wave form.

Namespace:  Un4seen.Bass.Misc
Assembly:  Bass.Net (in Bass.Net.dll) Version: 2.4.17.5
Syntax

public bool GetCuePoints(
	ref long startpos,
	ref long endpos,
	double thresholdIn,
	double thresholdOut
)

Parameters

startpos
Type: SystemInt64
Returns the position in bytes where the sound begins (cue-in position).
endpos
Type: SystemInt64
Returns the position in bytes where the sound ends (cue-out position).
thresholdIn
Type: SystemDouble
The threshold in dB (e.g. -24.0dB) which should be used to detect silence resp. sound at the beginning of the track.
thresholdOut
Type: SystemDouble
The threshold in dB (e.g. -24.0dB) which should be used to detect silence resp. sound at the end of the track.

Return Value

Type: Boolean
on success, else .
Remarks

If your rendering method and your playback stream used different flags during creation (e.g. rendering was done using the BASS_DEFAULT flag whereas your playback stream uses BASS_SAMPLE_FLOAT) getting the cue points might result in different positions, meaning the positions would reflect a different value during playback. But if you called the SyncPlayback(Int32) method this will ensure, that the position will be converted accordingly.

Examples

long startpos = 0;
long endpos   = 0;
WF.GetCuePoints(ref startpos, ref endpos, -30.0, -50.0);
WF.AddMarker( "CUE", startpos );
WF.AddMarker( "END", endpos );
