EAC, WMP, Audacity, Flac and WMA Lossless

Hi,

I heard a rumour that WMA lossless is not really lossless so I thought I'd do some testing.

I was screwing around a fair bit but then I realised that even when saving the same Audacity .wav file data to two different files, the latest version of Flac said they were different samples.

Anyway, ripping with EAC/Flac about 3/4 of the tracks apparently were 100% quality with the others listed as 99.9%.

So I thought I'd try ripping using EAC with WMA Lossless but it doesn't work on my Vista x64 machine with the 32 bit or the 64 bit version of Windows Media Encoder.

Would anyone like to try this?

Thanks.

WMA always sounded different to me.

Different to what?

EDIT: And are you talking about normal WMA or WMA Lossless?

To .wav.
WMA lossless or not.......there's something going on there.

When I use EAC, I rip everything to wav.
It's as close as I'm going to get to the original CD, and that's a long way from how it should sound as well!

But we won't go there...........yet.....

Really? I'sn't redbook audio just wav - thats what I thought. I'd like an answer on that one before I rip my entire cd collection to flac. :)

Read it and you'll see there's 8 bits of audio and 8 bits of error correction.
(I haven't read it for a long time so I may be out slightly)
Anyway, the way they do the error correction id brilliant.
I just found it amazing when I read it.

I'm not sure on wav, but I thought it was just a sound file with no error correction.
Haven't got time to check ATM.

From what I have heard and read in this forum, flac uses a compression algorithm and has no error correction, dithering, truncation or quantising.

All the others create distortion of some type during the conversion process.

Now-a-days, with hard drive space easier to get, using codecs that decrease the size of a file is not so important, but may still be useful for transferring/sending files across the internet.

Exactly Glenn.
Even portable music needs no compression these days unless they are cheaparsed bastards.

Music lovers should always srive for the best.

Yeah but with .wav files you can't specify stuff like artist, track number, title, album, etc.

My Waves have most of that file info, you just get it from fredb before you do the rip with EAC, and set up the tagging preferences in EAC.

That's what I do.
I thought everyone did that?

Nope I ripped my cd collection to wav about 6 years ago when 80gb hdd's were fairly big. So we can set up wav now to have all the nice taging that I want flac for.

I'll have to look into that, can I retrofit my existing cd collection?

RIFF (the actual format that "WAV" files use) does actually provide the means for that kind of metadata to be included.

Not all applications that manipulate these files, actually pay any attention to this metadata however.

Okay, thanks for the clarification.
