Tics in generated wave files
Sometimes, high frequency and high energy tics are generated in wave files.
This problem can be produced by attached file, using FluidR3_GM.sf2
With provided capture, you can see the problem is numerical overflow. Clipping should be added.
I added the wav file generated by: musescore overflow.mscz -o overflow.wav
This bug has been marked as critical because this problem is dangerous for ears and sound reproduction system.
