Noisy sound quality with Blackfin in WB-mode
...comparable to a PC/x86/Linux encoded/decoded file, when Speex was compiled with "--enable-fixed-point" only. The strange sound seems to occur only in 16 kHz WB-mode, not in NB-mode (I didn't test 32 kHz). I encoded using for WB-mode: # speexenc -w --quality 5 --comp 5 input-wav-16khz outputA.speex and for NB-mode # speexenc --quality 5 --comp 5 input-wav-8kHz outputB.speex I decoded with # speexdec outputA.speex # speexdec outputB.speex The decoded files can be downloaded at (156k each): http://www.stud.tu-ilmenau.de/~bege-mt/maennl1-16000-16-mono-speex-c5-q5-noblackfinopt-decoded.w...
