WaveFormGetCuePoints Method (Double, Double, Double, Double, Boolean)

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

Public Function GetCuePoints ( 
	ByRef startpos As Double,
	ByRef endpos As Double,
	thresholdIn As Double,
	thresholdOut As Double,
	findZeroCrossing As Boolean
) As Boolean

Parameters

startpos

Type: SystemDouble
Returns the position in seconds where the sound begins (cue-in position).

endpos

Type: SystemDouble
Returns the position in seconds 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.

findZeroCrossing

Type: SystemBoolean
If set to the cue points will be adjusted to the next resp. previous zero crossing in order to avoid clicks (if set to the cue points will be adjusted to a quiter sample only).

Return Value

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.
