Hi

I'm using EAC to rip and pass to FLAC, but since FLAC appears to be a major bottleneck, I'd like to rip to WAV and batch convert to FLAC overnight.

So, I've tried ripping to WAV with EAC, using a filenaming structure that includes all the tags, and then using Flac frontend to convert the WAVs to FLAC.

Problem is Flac frontend doesn't actually manage to convert anything!

I drag and drop the files into the window and hit compress, but I just get a series of errors:
from flac - ERROR: unsupported compression type 17
and then from Tag - File not found: 'E:\1979\Rock\Stevie Wonder\Songs.....flac'

I guess the Tag error is because the flac encode failed, but what is 'compression type 17', why is EAC generating it, and how can I make it work?!

Thanks in advance.

Unrelated to your problems with FLAC frontend, if you rip with EAC to FLAC, and find FLAC "a major bottleneck" (do you have a very slow system? FLAC encoding is quite fast for the most part...), why don't you use the option in EAC to postpone encoding?
Tools > Compression Queue Control Center > Make all compression tasks sleep
Then you can wait, and reactivate the compression for overnight batch encoding....

Thanks - it's not that fast a system, 2.5G Celeron 256MB Ram, but I'm ripping 4 disks at a time and FLAC tends to get quite backed up. It seems to reach a certain point and than things start to fall over! It's a bit of a pain if the flac processes die, 'cos the tag passing gets lost and I end up with odd WAV files everywhere. Plus I can't get Flac frontend to work ;-(

I'll try the queue sleep thing - I hadn't realised that's what it's for.

compression type 17 is IMA ADPCM (see http://www.sonicspot.com/guide/wavefiles.html#fmt). FLAC doesn't support that (don't know any lossless codec that does).

Right, but these are files ripped to WAV using EAC - the exact same setup (that normally calls flac), with 'External Compression' turned off.

Any idea what's going on?

I guess not :-(
