I was just looking at how TTA compared to other lossless codec and found that they have released version 3.0 today with source code and many binaries.

Here is what the site says :

• fixed compression mode for HW compatibility;
• more faster in operation speed;
• precalculated seek map added into the TTA format;
• can decode files with errors;
• reduced memory requirements for hardware playback.

They are now hosted on CoreCodec.

To my knowledge v3.0 has been available at least since sunday...

Yeah , its been out for while

OK, my bad, it was released one month ago !
So it would be nice to have it in comparison charts

BTW, like Wavpack it seems a good candidate for Matroska : fast and small.

But no lossy mode, let alone hybrid

Also, is it block based?

Alexander, Pavel, CoreCodec and myself have kept this kind of quite. In my case I wanted ppl, to get a feel for for TTA and do some comparisons. Especially the HA Crew. But, now that TTA is moving towards and getting hardware support I am sure you will see these comparisions becoming more apparent. This is only TTA's forth release ever (iirc) and I am simply amazed and the their code, the professionalism in their presentation and documentation as well as the improvements that they have mentioned as coming.

This is why I chose it to be hosted on CoreCodec.

If you want a lossy codec, get a lossy codec

Yes it's block based. The block size is fixed and about 1s long. (which is OK for video interleaving). And it supports even 32 bits floating source / 24 bits audio as well.

Not if I want correction file



Same thing about WavPack 4.

Sorry for no announcement about TTA 3.0.
Thanks for good words about our project.

As I wrote in another (TTA 2.0) thread - We are waiting for Neuston's firmware release.. It should be already appeared, but still in tests I think. It's our first firmware and we has planned to make an advanced announcement about it. Our code completely tested, but unfortunately last week I have no new information. Anyway we starting our collaboration with a 2 new manufacturers. New TTA supported hardware coming soon.

About lossy mode.. I has studied "dual stream"/hybrid technics.. Looks interesting, but in fact it sounds not better than MP3/OGG/MPC for me, and I think that this format is not conveniently. As about 32bit mode - it's just a tradition support for our codec.. Hardware library does not contain this code.

Is 24 bits supported in hardware ?

Hey ald, looks like adreses tta@iszf.irk.ru and sasha@iszf.irk.ru dont work (SMTP error). I tried some times, and always "Mail delivery failed" (

have you another adress to send questions ?

It's a main of our goals.

At now the player's code has a 24bit files support, but with a resampling to 16bit.
I'm already has ordered a good device for our future tests. Going to made a true 24bit support.

-- Alexander

Yes. I have another addresses, but use @iszf.irk.ru only.
You can to use a PM (personal message) service at this site if SMTP errors still present.

-- Alexander

TTA 3.1 with the updated set of plugins is released.

- added -t 'test file' option;
- added support of the WAV files with ID3v2 tags;
- corrected shown bitrate & code cleanup in all of plugins.

I has placed the encoder, hw-player library and a plugins code into the CoreCodec.org CVS server.
C++ encoder/decoder TTA library coming soon.

-- Alexander

And I did my trick again: a new frontend that supports TTA 3.1 (and older versions).
Get it while it's hot!

RW Debian Rep updated, too (with html update! oh joy! hehe)

later

Speek, xmixahlx

Thanks for updates.

Hi,



I think, it's a temporary problems at corecodec.org. We have a local mirror of our project. Please use following links while corecodec.org is not accessible:

Alexander,

just wanted to tell you, that my little tagger supports TTA since the latest release.

Best regards,

Apparently you're missing MKA support

Has MKA tagging been standardized at last?

I was under the impression you guys were still compiling a huge list of possible tags that might or might not be bigger than MPEG7.

Its 'mostly' standardized. The structure is standardized, so it is usuable. And most of the common tags exist. There are just a few troublesome tags that are being worked on right now. I'm in the middle of moving though so its slow. Once everything is worked out, the plan is to make examples of where everything should be stored so that there isn't confusion once it is widely used.

While encoding I noticed that I never reach more than 80% of CPU usage. I suspect it might come from the I/O level (tested under Windows). Maybe you should investigate more on this and you would have even faster encoding on fast machines (I have a rather modest XP 2400+ with an Hitachi 7K250 HD).

Thank you for supporting TTA in your project.


Nope. I like MKA, but unfortunately I have no time to think about it now.. maybe at Autumn.. ;-)

Actually that was not for you
We'll help you support MKA, or even make it completely (at least in our tools). Most important to have a DirectShow filter that we could easily do once you have a standalone library...

Other news for you, someone made an experimental TTA GStreamer plugin based on the current code.

Sorry for mistake & thanks for great news.

P/S WinTTA GUI coming soon with a new encoder/decoder library.

-- Alexander

Great, I'm looking forward to the new encoder/decoder library.
I already made a DirectShow encoder that works with MKA but it's better to wait for the new library to finish that and do the decoder.

TTA news:

1) TTA input plug-in for Quintessential Player (QCD) is released.
