to transcode 2 mp4 files downloaded from youtube, to wav.
All went well - the wave files sounded just as good as the YT mp4 versions.

Then I installed
mac-libs-4.11-3.u4b5
mac-4.11-3.u4b5
mac-devel-4.11-3.u4b5

and converted the 2  .wav files to ape using the command line


mac file_1.wav  file_1.ape -c5000

and it exited with Success.

However, playing the two files, I only hear white noise.

PS: I do understand that this is not the list to report issues with the 
program "mac",
but I am hoping to receive some feedback who have successfully 
transcoded to ape.

Thanx.
