Sometimes, when a .wav sound is played it will repeat itself after it's done playing. (plays twice) If it's a longers sound, it will just play the end-part. I believe many of you have encountered this before, so I'm asking you is there any way to fix this?
None.
I have encountered this, where the very end of the wav repeats itself for some reason. I think maybe becuase the file is bugged or something. Or maybe has something to do with the wav file type.
I honestly cannot help you with this but to suggest either ignore it, or look for a new sound to use!
Good luck.
None.
I changed the .wav and it works now. But still, if anybody knows the reason for the repetition, please tell me.
None.

Actually I never heard of this bug but my guess would be non-standard wavs that have false length/sampling rate information.
For example the track header says it has 1,15 seconds but the sound has finished playing after 1,00 seconds and repeats the last bit until the recognized playing time is over.
Try to convert the sound into another sampling rate/channel/bitrate to recreate the header.
Or maybe it's a bug in ScmDraft. Try the same sound in another editor.
