Hi,
yes, I discovered this, the problem was my file was called in.r, not
in.raw. When it said unknown file type, it really meant it didn't know
what audio was in the file, but I thought it meant what type of file it
was (pipe, file, character device, etc)
Now I am seeing the reverb (etr) effect is rather sharp, it is like a
mountaintop, and I want a hall or cave. What options could be used to get
this?
