What is the best Wav or flac when you rip the audios sound from a DVD to a CD.

It is a good question

It's the same, in fact of sound quality.
FLAC is a lossless encode, so it leave the full range frequency in the audio files.
WAV is the same as FLAC, but NON compressed, so they take more space.

As long as your burner accepts Flac (and most do), it doesn't matter (as explained by Andrea82) Only if you want to keep the files on a HDD too, Flac would be better, just to save some space.

Thanks Chris

The question is:
lossless LPCM or lossy AC3 audio track on DVD!

LPCM >> wav/flac
AC3 (128 to 448 kbps) >> mp3

There is no need to convert AC3 (lossy) to wav/flac (lossless).

Yes. Lossless audio (from a video disc) is usually reserved for Blu-ray Discs.

There is no need to convert AC3 (lossy) to wav/flac (lossless).

When you convert an already lossy source (AC3) to mp3 you loose even more quality because mp3 encoding is lossy again.

Converting lossy AC3 to wav/flac at least does not degrade the quality any further.

Given FLAC ubiquity today there is little reason of using WAV for common tasks. The sound quality is the same.

Spectrum analysis of "Let It Bleed", ripped from the Paradiso DVD with Aimersoft DVD Ripper to wav (55.19 Mb):









From this wav to Flac with Flac frontend (38.40 Mb) (I don't see any difference, LOL!):
