[TriLUG] .wav to .mp3

[Brian A. Henning]

Hi,
  No, see, CD-Audio *is* *PCM* format.  Exactly the same format as a .wav
file, aside from header info.  MP3 is compresssed; no plain-audio CD player
known to man will play a CD burned with MP3s---technically, you *can't* burn
an audio CD from MP3s; MP3 format straight to CD == data CD with MP3 files
on it.

  I think what you're worried about is the fact that some (older?) CD
players simply can't handle CD-Rs.  Anything from skipping a lot, to hanging
between tracks (make sure you burn in Disc At Once [DAO] mode to help avoid
this), to simply not recognizing the media at all.  There's no way around
this, I'm afraid. (FYI, even fewer audio CD players can handle CD-RW;
general rule here is if it doesn't specifically advertise itself as able to
read CD-RWs, it can't).

  So here are some general tips to help:
1) Make sure you're set to burn an Audio CD, not a Data CD of WAV files;
[I'm pretty sure] there is a difference between the two in the area of
filesystem structure.
2) Don't convert to MP3.  Honest.
3) Make sure to select Disc At Once [DAO] mode.  This prevents the write
laser from turning off between tracks.  (Most howtos just say
non-disc-at-once results in 2-second gaps between tracks; however I know
that my Sony Discman hangs between tracks if DAO isn't used).

Good luck!

~Brian

The reason I want to convert to an MP3 is to assure that I will be
playable on a cd player.  Some dont seem to handle the wave file.
By the way, quality here is NOT an issue.  It is a recording of my son
on an on air radio broadcast.

Thanks
