What's the use of uncompressed flac? Wouldn't that be the same as saving the WAV?

I only use the VorbisComment to PCM.

After skimming the website he linked: Probably because he is afraid compressed FLAC somehow sounds inferior to uncompressed FLAC. Which is bullshit, because they're both lossless and when decoded result in the same bits....

Sure he's free to do whatever gives him piece of mind. I was just arguing that it's not expected to make any difference.

People can believe whatever fanciful things they want, but if the motive for ‘uncompressed FLAC’ is related to ideas about sound quality in any way, the site’s rules clearly state that such things, which are as nonsensical as they are unsubstantiated, are not welcome. Believe it if you must: just don’t expect people with standards to listen to you.

To be clear, I’m not psychic and therefore not stating either way that kokuyo’s request is or is not motivated by claims about sound quality – but if it is, (A) you’re wrong, and (B) keep it to yourself.

I think that sound quality is the same as uncompressed PCM.

And I think the FLAC tag is more convenient. The Japanese tag information is not well displayed by a non-compressed file.

Thanks.

True, but the same is probably the case with compressed Flac... When implemented right decoding either compressed or uncompressed should result in exactly the same bits (same as original source).

Decoding? Encoding. Should? They are.

Yet and again, he's free to do whatever he wants even if I agree and don't understand why he's not using compressed lossless.


ozok, thanks for the update. Any news on %discnumber%?

Yes. The sound quality of FLAC (compressed or uncompressed) file format is exactly the same as uncompressed PCM. So why do you want uncompressed FLAC?

Tag data are encoded in UTF-8, and so any Unicode string may be used as a value.

Thank you - but that page (and I am afraid something got lost in translation) seems to talk about why you should use FLAC instead of WAV (in order to deal with Unicode tags). It doesn't seem to provide any explanation as to why you would want uncompressed FLAC instead of compressed FLAC.

i think the common myth is that the more a file is compressed, the more CPU it will take to decode and this has a negative affect on sound output. laugh.gif

admittedly, i've only seen this sort of nonsense posted by WAV users. i've not encountered uncompressed flac before.

I often use compressed FLAC than uncompressed FLAC and the un-compressing is also as a part of option with this software.

Thanks.

And I want ths app to add saving profile.

Just want to thank you ozok!
TAudioConverter works greater than ever. No big problems, and seems like your last tweeking made the whole thing faster and sleeker smile.gif
All that's missing is CUE-support and support for some more tags (%totaltracks%, %disc%, %totaldiscs%). But there are other ways, so no problem really.

Functions you could add in future:
- GUI for mp3repacker. The ability to compress CBR mp3's without loosing quality inside your program would be awesome.
- Also would be great if logs were kept in a folder. The TAudioConverter folder becomes very messy with all them log files smile.gif
- Ability to disable ALL logs, not only encoder logs.
- Warning when converting lossy->lossy (Not everyone understands how that might degrade quality)

Bugs i've noticed:
CTRL-A function is great. BUT it functions also when editing fields like "Output Folder". Try to add some files, go to output folder, ctrl-a (to mark all text), then delete. The tracks in list disappears.

Thanks for your hard work!

Forgot to add: Ability to tag output files using the tags. Like
"%artist% - %year% - %album% - %track% - %title%"
which gives
"In Flames - 2008 - A Sense Of Purpose - 01 - The Mirror's Truth"

That's actually implemented, somewhat limited. Settings>Encoding>Create folder structure in output(checked)>Custom folder tree. You can see supported tags by clicking "Help" button.

Just a Quick Problem: The AAC(FFMpeg) encoder only encodes in 128kbps, even if selecting other bitrates.

Can you please also add ALAC decoding/encoding? (It's already supported by ffmpeg)

Both encoding and decoding ALAC is already supported. He uses REFALAC instead of ffmpeg

@norc426 I can confirm that error. Although TAC passes right bitrate, ffmpeg encodes files to 128kbps somehow. I'll look into it.

TAC can't read mp3 files repacked by "mp3repacker". Why is that? When trying to add one of those to the list, it disappears.

Can you read info (duration, bitrate, tags) from these files with MediaInfo? You can send me a sample too.

I don't think it has anything to do with tags. I resaved them using "TagScanner", TAC still don't want the file.
