Title: Oddball FLAC error
Post by: TNJazz on December 28, 2006, 07:48:16 AM
Recorded several 24 bit files for a project this past weekend.  When I go to FLAC them, I get the following error:

ERROR:  block size is 3; must be 0

It doesn't compress any files at all and burns through all 8 of them with the same error.  This happens both in xAct on the Mac and in Frontend under XP.

Anyone seen this before?

just curious... did you do any processing to the files or are you just FLACing the raw files?


from looking at some quick stuff I found by googling FLAC blocksize it sounds like it might be a bug in the software you are using. without getting too technical it looks like instead of allowing the encoder to estimate the blocksize it is trying to force a blocksize. According to what I read it is best to let the encoder estimate a blocksize.

what software are you using? did you try any other software to flac the files?

xACT just calls flac directly, and i believe frontend does, too, so i doubt anything else would have success. 

where are these files from?

I guess my questions were a little stupid since they were clearly answered in dirk's first post. you'd never know I fix software for a living  ;D

These are 8 tracks of 24/48 aif files that I recorded last weekend using the Metric Halo record panel (which writes aif files automatically).

I tried to drop them into mkwAct just for fun, and they didn't even register.  The files seem to work just fine as aif though - when I build a project in Nuendo or Cubase I don't notice any anomalies in the wave files themselves.  Everything plays and works just fine.

I thought the Metric Halo record panel wrote in sd2 format?  not aiff?

The new record panel has the option to select SDII or aif (even wav, I think).

i wonder if it has some strange header info

did you try the -lax setting in xACT?

No, but I'll try it when I get home tonight.  I believe this might be the first time I've written aif files with the Halo...could very well be a MHLabs issue.

-lax has no effect.  Still the same error at the same speed (immediate).  Very curious.

have you tried converting the files to aiff or wav in another program?  i think the MH record console is writing some strange header

I agree, this sounds like a problem with the MH software.  What can I use to do a conversion?  Is there anything out there that converts aif straight to wav?  I'd rather not open up each file and re-render them if I can help it...

You can open them in cd wave and then save them under save it gives you the option to as many different file types, I have used this to bring a few files back from the dead in similar situations. good luck!

open them in any editor and just resave
