similar to: FLAC: decoding to WAV in the future

Hi Harry, First of all, if you keep a copy of flac 1.1.4 then you will always be able to decode the files. Why not make a backup of flac 1.1.4? Second of all, flac is open-source, so somebody will always be able to compile flac 1.1.4 for any new platform. There are never any guarantees about the future. Some day, MP3 won't decode on a new computer, AIFF and WAV might be unheard of.

What Brian Willoughby means is that even though the future is uncertain, you may trust FLAC. The format is mature enough so that you won't see major changes preventing playback of files encoded by older encoders, but even if that comes to happen, the playback libraries on most software will be backwards-compatible, and FLAC is lossless meaning that you may convert FLAC 1.1.4 to a possible

So some research and experimentation I think I found the problem, but I'm not sure how to go about fixing it. If I import one of the wav files into Audacity then export them as "16 bit PCM" then they encode to flac and play fine. The files bitrates are currently at 24. If I export them from audacity as a 24 or 32 (anything higher than 16), flac fails on me. With a bitrate of 24, the

I have exactly the same problem. I encoded a BWF file to flac and then then decoded back to wav, using --keep-foreign-metadata, and I ended up with a bit-perfect copy of the original BWF. So I was fairly confident that the flac encoding is working correctly, the problem definitely appears to be with the flac players. Unfortunately it seems that the majority of flac players cannot play 24bit

hi, according to the FAQ flac supports multichannel formats. i had no luck with 1.1.4 though ( "Untitled.aif: ERROR: unsupported number channels 8 for AIFF" ), i guess that feature was added in 1.2? unfortunately, the binary for 1.2 does not run on OS X 10.4 (says libiconv is too old). i removed libiconv and reinstalled that from source, but then flac 1.2.1 just prints

yes that is what i did. got the "requires version 7.0.0 or later, but libiconv.2.dylib provides version XYZ" (forgot which version i had before). removed libiconv, downloaded compiled and installed the new one (libiconv-1.13.1), then i just get $ flac Bus error i reinstalled flac 1.1.4, still runs fine (but doesn't support multichannel). cheers, -sciss- Am 05.08.2009 um

Thank you for the reply! I know that my system can play flac files, I've played others I've managed to convert using both of those programs. I'm only running into difficulty when it comes to these large WAV files. By "Does not work" I mean that they do not play, and instead I receive the errors I mentioned in my original post. I wasn't actually intending to use

I thought that an uncompressed FLAC file provides better sound quality than a compressed FLAC file.

Hello, I'm attempting to convert fairly large WAV files (90 - 800 MB each) using flac but the files do not work after the encoding. (The play fine in wav format) Command I'm using: flac --verify -8 file.wav Attempting to run the file with either flac123 or the default player for Ubuntu (Movie Player?) results in the extremely terse messages: Default Player: "An Error Occurred:

Thanks for all the responses to my question. I think I can use shntool hash option for my project I did not find in the shntool documentation or flac documentation that the hash or st5 always would match the flac fingerprint. But at least in a couple tests I did they matched. And I found some more comments around the internet indicating they were the same. -----Original Message----- From:

Great info. I found some descriptions of st5 (md5 fp) and ffp, where I assume that "fp" is just a Taper abbreviation for "fingerprint" - or signature as it's called in the flac header. However, I could not find these utilities or source code. What I found looked like instructions for a gui-based program. I think it would be easier to support Mac if st5 were

Hello FLAC list. As far as I know 24 bit FLAC support is broken. It often doesn't compress the audio at all, but instead stores the chunks as verbatim type (although the FLAC format supports 24 bit). Perhaps this is fixed? If so, do let me know. I agree that perhaps 32 bit float/pcm isn't entirely necessary when it comes to storing different qualities. But when wanting to preserve

In windows command line: I have a wav file and would like to see what the flac fingerprint would be. To do this I run flac to encode the wav file and write the flac file to the hard disk. I then run metaflac to read the flac file and display the fingerprint. Is there an existing way or other utility to do this without generating the flac file on the hard disk. I would think it could be quicker

I am trying to decode 192k/24 bit flac on 542 MHZ risk processor, and I am having problems. I seem to be right at the edge of what this processor can do. So I am wondering what functions would be canidates for assembly code optimization? Any suggestions? Or could an older version of code be a batter candidate to use?
