Hi

I've just installe FMod and played around with it a little - but it doesn't fit the purpose for which I've installed it yet. The thing is: I've got several songparts and each of them perfectly fits together with each other songpart. I want to mix them up and play them in a random order to achieve having one big dynamic song. The reason why I'm using FMod and not BlitzMax's internal sound is that BlitzMax always leaves a small "gap" between two parts.
With FMod, that gap is gone but I've still got a hearable "crack" when finishing one part and starting the next.

Here is my code:

SuperStrict
SeedRnd MilliSecs()
Graphics 800, 600, 0, 60

FSOUND_Init(44100, 256, 0)

Global ifmsOne			:Int	= FSOUND_Stream_Open("Engine-Class4.wav", FSOUND_NORMAL, 0, 0)
Global ifmcOne			:Int	= -1
Global iPlayTime		:Int

Repeat
	Cls
	
	If ifmcOne = -1 Or (MilliSecs() - iPlayTime) >= FSOUND_Stream_GetLengthMs(ifmsOne) Or FSOUND_IsPlaying(ifmcOne) = False Then
		RestartSound()
	End If
	
	Flip
Until KeyHit(KEY_ESCAPE)

FSOUND_Stream_Close(ifmsOne)
FSOUND_Close()
End


Function RestartSound:Byte()
	FSOUND_Stream_Stop(ifmsOne)
	ifmcOne = FSOUND_Stream_Play(FSOUND_FREE, ifmsOne)
	iPlayTime = MilliSecs()
	Print ifmcOne
End Function

And here's the soundsample for testing. A simple engineloop:

Also, keep in mind: This is not a looping problem, because I don't want to loop anything. I *have* already discovered the loopingfunctions.
