The > question, why there is not the same behaviour on Win32 remains. It turned to be a downsampling problem under Linux: Below a list of input fileformats and standard quality settings == 5: 48000 Hz 16bit mono -> signal distorted 44100 Hz 16bit mono -> signal distorted 32000 Hz 16bit mono -> signal OK 16000 Hz 16bit mono -> signal OK regards, Thomas
