[Csnd] HRTF issue between -odac and file output

Subject[Csnd] HRTF issue between -odac and file output
Hey hey,
I am experiencing an issue with the hrtf opcodes. When Csound is running in 
realtime the sound is fine. But when the output is an audiofile (with all 
other settings unchanged) there is a quite static tone in one channel and the 
hrtfreverb late reflections sound like they are compressed or have rendering 
artefacts.

Here is an example audiofile:
https://www.dropbox.com/s/nb9r1mmmwtprtor/toms.mp3

The  section has these flags:
-o toms_1.wav -d --messagelevel=2
No further options added on the commandline.

Csound version is 6.16 (Arch package from 2021.07.29 .

Does anyone have an idea or can reproduce this behaviour?

Best wishes,

Jeanette

The described artefacts in rendering were due to the fact that the audio file 
was rendered at 16bit. Though the artefacts were surprisingly distinct!
