Title: FLAC help with Ubuntu
Post by: Nick's Picks on August 31, 2009, 08:44:02 AM

I'm having trouble seeding FLAC files via a Ubuntu DAW...and need some help.

using Audacity.  > export files as raw 16bit PCM (as it opens them as 32bit).
I then use "sound converter" to run the wav files through and it outputs as FLAC.

nobody can decode them.  all sorts of fucked up errers, reporting as 32bit ..etc etc.

HELP !!!!!!

have you tried calling flac from the command line? (I'm trying to eliminate audacity as the culprit).

Second, if your not willing or interested in doing that, have you considered just exporting to 16bit flac from audacity?

I'm learning the command line..., but need some intructions.
I've tried making FLAC files via every possible way (including direct output from audacity).

type flac --version
what do you get back?

Given a 16bit wav file (both that you've created under linux and one that's from a different and confirmed working source): try encoding it via this method:

flac --best -V --sector-align file.wav

In Audacity... Edit -> Preferences -> File Formats.... mine is set to "WAV (Microsoft 16bit PCM)" or  "Other"/"Signed 24 bit PCM" if I'm saving to 24bit.
Then I flac from command line using "flac *.wav" with no special parameters.

"shntool len" is your friend... if it comes back with something clean like below you are good.  By "clean" I mean all those hyphens under problems is a good thing.  When you see "c" in the first column is means it's not 16/44100 CD quality.

Try the newest (beta) version of Audacity...you can track and save directly to FLAC -  SBE free...

so what I ended up doing..was taking the hard way around.
Installed VMware, then I installed an XP virtual machine.
now i'm re-encoding the files with TLH, and everything should be rosy.
