Default Turn MP3 inot CDDA disc

I have a 2hrs mp3 I want to edit to a 70 minute regular audio CD. I have VLC
and Windows media player. Sound Rec from MS might edit it if it is a WAV. Is
CDDA really WAV?

No... but they're cousins.

CD Digital Audio is recorded as two channels, 16-bit linear samples,
44100 samples per second per channel. A "cdda" file is typically just
exactly this data - the audio samples in this format, with nothing else
at all in the file.

WAV format is a "container", not a specific digital-audio format
specification. A WAV file can hold audio having many different
combinations of channels (mono, stereo, or more), sample format (8- or
16- or 24-bit), and sample rate (8000, 44100, and 48000 are common).
A header block in the WAV file identifies the specifics for the data
in the file.

MP3 is a lossy-encoding format - like WAV, an MP3 file can contain
audio streams having various combinations of channel count and sample
rate.

Since you want to burn to CD, you're going to need to end up with
either a CDDA file, or a WAV (or FLAC) file that's compatible with the
CD-DA requirements (44100/2/16).

Probably the best approach is:

(1) Decode the MP3, storing the result as a WAV. This won't result in
any quality loss, since the MP3 format is "lossy" in the encoding
step, not during decoding.

(2) Check the WAV and see what its channel count and sample rate are.
If they aren't 2 channels 44100 samples/second, you'll need to
convert to this format (probably just a "sample rate conversion").
There may be some slight quality loss during sample-rate conversion,
but it can be done extremely well by software packages (I'd use
"sox" on Linux, probably).

(3) Edit. If I were doing it I'd probably use Audacity, exporting the
edited file back to a new WAV. This can be done without significant
loss (the worst is likely to be a slight click at edit points, if you
cut the waveforms at the wrong points).

(4) Burn the WAV to CD - most burning programs will accept a WAV
file as long as it's got the right channel count, sample format,
and sample rate.
