Blu-ray Audio to MP3

Hi.

The music companies are selling 48khz/24 bit, stereo lossless Blu-Ray discs.

Now as far as I am concerned, 48 khz/24 bit lossless is not better than 44 khz lossy highbitrate MP3. However what you do get with these discs is a much better chance of a high-quality master that hasn't been subjected to dynamic range compression.

In other words, these discs are better, but not because they are blu-ray.

Anyway. that being so, if I am going to store these discs on my HD, I don't want a 12GB/hour M2TS file consisting of duplicated LPCM, Dolby True HD, DTS, etc. streams, I'd actually just like a 320kbit MP3, at like 1% of the size.

And I'd also like ID3 tags to be filled in automatically.

Anyone know software that can help with this process?

Assuming the BR has no encryption I believe you can use DVD Audio Extractor. It doesn't seem to mention it in features but it says:

7.0.0 (2012-08-15)

    DVD Audio Extractor now supports Blu-ray discs.
    The CD Image and Cuesheet format can now be used to create DTS-CD image.
    Supports decoding audio files that is demuxed from Blu-ray and DVD files, like dts, ac3, mlp, thd, etc.
    Other minor enhancements.

Assuming that you have an mkv file, the ffmpeg tool will help you extract a single giant wav file. Unfortunately, I don't know the easiest way to chop it up and tag.

Example:

ffmpeg -i stereo_mix.mkv full_album.wav

Make sure that you choose the LPCM source as your codec, if available.
