Annoying Problem with Audition

[experimental.crow]

I use the highest possible settings:

Output: Wave
Depth: 32 Bit Float (0.24)
Bit Rate: 320 KBit
Sampler's Interpolation: Sinc Depth 256
Dithering, Alias-Free TS-404, HQ for all Plugins, Disable Max Poly.

I don't think it's necessarily the wave file itself since the problem happens on any format I use (wave and MP3s).

S-graph

so you render ALL your .wavs at 32-bit , and only SOME of these .wavs have problems ?...

just as an experiment , try rendering your .wav as 16 bit , 44.1k ...
i seem to recall some problems with the 32 bit FLS render ... i don't use 32 bit FLS render , but i'll look around for the
thread where i seem to remember this being discussed ...
