I know ... Thats why I downsampled the WAV-File to 8kHz (I got to know
sox just last night, so I did this a little late). Then, I used speexenc
-n. submodeID 5 is still used always.
That, fortunately, simplifies my test scenario. So, as long as the input
file is sampled at constantly 8kHz, the submodeID sticks to 5. Looks
good to me.



You will be awarded some great honor.
