Hi list
First of all, thank you for the amazing framework. We are using it in
our lab at UNICAMP/Brasil and we are impressed with it.
I have two newby questions:
1) I can read mono audio files with MultiChannelAudioFileReader but I
can't write them with MultiChannelAudioFileWriter. When I've tried to
do this I've got a segfault. The code is attached. Is it correct? I'm
using the deb package for (k)ubuntu feisty.
2) What is the standard interface to read and write files:
MultiChannel/MonoAudioFileReader/Writer or AudioFileIn/Out? Why are
there two different interfaces?
Thanks in advance,
Fabio
