Comment (by Kamedo2):

 In 4 hours of hearing more than 100 musical, vocal, ambient and artificial
 sounds, on 64-480kbps, 44.1kHz, 48kHz, stereo, surround, I have found no
 problematic samples. This solution is great. Thank you for fixing,
 klaussfreire.

 I think I'm going to test mono, collecting more surround samples to test,
 32kHz or less, and VBR modes tomorrow.
