Are imported MP3s converted if FLAC compression is enabled?

Hi There,

I’m almost done ripping all my CDs onto my B2, so I’m now thinking about all those old mp3s I have on my laptop for which I have no disk. If I have my B2’s compression enabled for FLAC compression, will those newly imported mp3s be converted to FLAC or does the Brennan know not to do that?

Thanks.

Hi Nick,

I've been down this path myself!  The short answer is that if you copy your mp3 files across (say from a PC or other device), the B2 just accepts the mp3 files as they are and does not convert them to FLAC.

So, in my collection, I have approximately 5500 FLAC files (from newly ripped CDs) and 13500 MP3 files (from files copied from my old music system).

Regards,
Peter.

Thanks for the info, Peter. Would you happen to know if the same holds true for AAC files?

Hi Nick,

The B2 (and BB1) will only compress WAV files (the original format of a CD). It will not attempt to compress FLAC, MP3 or AAC/ALAC files so will they remain in whatever format they were loaded in.

One added point of information:
There is no reason to convert MP3 files to FLAC.  Doing so cannot improve the resolution (or quality), but it would make the file bigger.

When a WAV or FLAC file is converted to MP3, data is thrown out.  Once discarded, that data cannot be recovered, it's gone.

I'm sure the B2 does not do this because there would be no good reason for it. MP3 is a lossy compression; it leaves stuff out that you can never get back, and hopefully you won't notice. FLAC is a lossless compression; it compresses without loss of fidelity, so you can always convert it back to the original WAV if you want. To convert an MP3 to FLAC would simply result in a bigger file and wouldn't provide any improvement. It would simply be a lossless rendering of an already lossy file. Whatever is missing in the MP3 conversion won't magically come back if you turn it into a FLAC. It is lost forever. And if your MP3 has birdie artefacts (those R2D2 noises breaking through silences and dancing over harpsichord solos) converting it to FLAC won't, alas, make them go away.
