Title: FLAC compression problem, 2 tracks??
Post by: gmm6797 on June 01, 2008, 08:41:57 PM
I am not new to FLAC or compressing tracks, but I am new to my Marantz 671.

I recorded a band that plays for nice long sets, Max Creek.

My Set 1 48/96 WAV file is 2.8gb and my Set II 48/96 WAV file is 3.3gb.

Neither will compress in TLH or in FLACfrontend.

Is there any way to turn on error reporting in either so I can get some sort of an idea as to why these are not compressing?

The files play find and I have already done my editing and tracking of files, but now I want to compress these and burn them off to DVD.

You will have to change your bit depth to 24, at least.  I am not sure about the sampling rate.  You might want to leave the masters as they are, edit and track them and then convert those tracks to FLAC.

Well, I have the files that I edited (normalized, etc) all FLAC'ed up, but these are the master WAV files and I am trying to keep them preserved and compressed.

The standard WAV file format has a maximum size of 2GB. Maybe you could cut them in half and archive the halves?

Why not just make a MD5 checksum for each WAV and burn em on DVD-R's as data? That will preserve them. (make a spare copy, just in case!)

I thought the WAV file size limitation was an OS issue, not a file format issue?  NTFS and FAT are 2gb per file, but FAT32 and others are unlimited, no?

And no problem burning them straight to DVD with the MD5's, but was hoping to save a little space.

what version of FLAC are you using, and what is the last program that you are using before trying to compress to FLAC?

you can flac wave files over 2 gigs.

Input or output?

I tried the current FLAC 1.2.1 and the one version back 1.2.0, all on Vista 64 bit Business edition.

The files are still untouched/edited, as they were copied off of the 671.  But I did look at them in SoundForge9.x

pretty sure both.  you just can't open them with most audio editing software.

I was about to ask what the error was.  in both programs you should be able to see it. with frontend the dos window will display the error and in traders little helper just look at the bottom in the process log.

On the 3+gb file, there is no error in either, it is like it just never finishes.

Ill re-run the 2gb one now and report back

See attached for errors... TLH just hangs, so there is nothing else to see

ok.  the first warning is fine (legacy etc).  the sub chunk error is common but I've never seen that many.  ussulay the "sub chunk" has to do with the recorder writing some unknown info on the wave file.  generally flacing it will fix (remove the chunk) this no problem.


what I would try is this


open them in soundforge 9 and then save them.  no editing etc, just save it over writing the original.  then try and see if it works.  I'm betting it will.

Good idea, though I'd Save As a new file, not Save and overwrite the original.

doh!  that's what I meant.

I did the save and the save-as over the original... both saves were just mere seconds (strange).

And both results the same, except the TLH actually crashed out this time.  FLAC dos window, exact same results

ARGH!

Saved the D01T01 file to a completely new name, same results.... fun fun

try opening the files in cdwav and save as flac from there.

Never tried that, what options should I pick in CDWav for the FLAC settings?

Your problem I bet lies in how SF9 is saving the file. I bet it is saving in w64 format since the "wav" files are greater than 2GB. I bet your only option is to split the files smaller than 2GB and save as a standard wav file.  ;)

I do not believe that is the issue, as these are the original files that the Marantz 671 saved...
but the test WAV files I did have SF9 save, gave the exact same results

8 takes the longest to process but gives the smallest possible output files, if I understand correctly. Doesn't take THAT long, so I go for 8 unless i forget- then I think the default for xACT on the mac is 5 or 6.

I did the CDwav @ 8 and it took a few minutes, but no biggie... and they are all set, thanks for the suggestions

+T all around
