Lossless Query

[anirban]

Suppose I have 2 same tracks (lossless) ripped from 2 different AudioCDs...
So how to understand that they are both same in sound quality...

Any tool for analysing some wave patter or something like that as I have seen in few places where they prove using some wave pattern that ripped one(FLAC) are same as original AudioCDs...

same as original AudioCDs...

That's the definition of "lossless".
So a FLAC file can be decoded back to EXACTLY the same wave file as was used to generate it.
(Actually, first you have the problem of ripping an audio CD to wave on your PC. Probably the best way to do that is EAC.)

Yeah i know that but my question is not answered...

You didn't ask a question.

CLI: fc /b file1 file2

Or any other binary file comparison program.

Take an uncompressed rip. Compress with flac. Decompress with flac. Compare the original uncompressed file with the decompressed file. The data will be identical.

Tau Analyzer
This is what I was looking for...
Thanks anyway...

If you'd said you wanted to compare the quality of the audio ON THE CDs, instead of "2 same tracks (lossless)", maybe someone could have guessed what you wanted.

The only problem with that program is it will not check files on your pc.... you have to actually burn them to a cdr to analyze them.

I tested it with some high bitrate mp3's i made, some FLAC's i DLed and some FLAC's i made myself from original cd's and burned back to a cdr, and it was correct on identifying them all.

It would be nice though if it could scan files on your HDD before using up a cdr to tell you if they originated from a lossy format or not.

"AuCDtect uses WAV files data, from a command line".
Download from http://true-audio.com/Free_Downloads

Otherwise, maybe you could use a virtual disk, like Daemon Tools. Or a CDRW.

Yeah, thats what i downloaded.

If it has an option to read wav files off an HDD they hid it pretty damn good

And if there is another way, they hid it very well also.

Just saying it would be nice if they had the option to be able to just open a single wav file and scan it.

Hey guys for HDD files + AudioCDs..
Use AudioChecker

No it isn't.

Get AuCDtect not Tau Analyzer.
