I'm currently transcoding my entire collection from -p4 to -p5m. I'll post data soon.


Yes, please do.  I'm definitely interested in what results you get

+1 for piping

TAK 1.0.2 - Beta release 1

O yes, it is... At least if you are working with the command line version. Please try this: "-p3m,pf0". It will disable the PreFilter which is responsible for the slight decoding speed penality. I will also make this option accessible in the GUI version.


Thanks, it seems to be very close to the 'legacy' normal max, I'll experiment a bit with it when I'll have some time

IMHO, piping support is one of the most important features at this moment.

New preset p0 with 8 predictors  results very interesting for transcoding scenario.
It's faster for en/decoding and has higher compression than FLAC -5 ... -8
Is it possible to see even lower complexity turbo preset? This way it will have compression ratio like FLAC -8 and complexity of FLAC 0. The main goal will be very high decode speed for transcoding lossless to lossy.

Thank you very much! Nice results...

Some remarks:

Code: [Select]
1.0.1b    TAK Turbo           64.929%    104x    118x
1.0.2b    TAK Turbo           65.281%    110x    129x

I like this new very low complexity preset. The speed advantage over old TURBO isn't big but significant and the compression efficiency is still good.

Code: [Select]
1.0.1b    TAK Normal          63.875%     45x    109x
1.0.2b    TAK Normal          64.093%     62x    113x

You always told me, that you would like to see a faster NORMAL preset.... Normal is now using only 32 predictors which does make perfect sense, because 32 is the most bang-for-the-buck-condition (efficiency / complexity). I should have done this earlier, but there was some kind of a psychological barrier in my mind: Before the first publication of YALAC/TAK i have always focussed on strong compression and not on speed.

Code: [Select]
1.0.1b    TAK Extra Max       63.527%      7x     87x
1.0.2b    TAK Insane Max      63.532%     10x     93x

A nice encoding speed up for the guys who are always using TAK's strongest mode. It's surely worth the compression disadvantage of 0.005 percent. As you can see, i have also improved the decoding speed a bit.

To summarize: I really like the new preset configuration.

I could reduce the predictor count from 8 to 4. But this doesn't make much sense. First you will loose about 0.7 percent of compression. Second: The effect on the decoding speed will be hardly noticable. Going for 4 predictors would have only one real advantage: I could significantly increase the encoding speed.

BTW: I am working on a new codec which -among other things- will decode a bit faster (currently about 6 percent for Turbo).

I don't know what others need but oftenly I need to compress wav files to FLAC -0. It permits instantly save a space just  for really very short time.
0.7%  isn't that much for this purpose. The difference per cd will be 2-4 mb.  And compression ratio may be as good as FLAC -5.

I try to see TAK as alternative  to my FLAC rips

Have you found any bugs?

I would like to release TAK 1.0.2 Final. If you have found any bugs in the beta, please tell me now!

For the feature requests

Hm, seems as if the winner is piping... Hopefully i will implement piping support for encoding in V1.0.3.

Fine! 

According to Synthetic Soul's comparison TAK Turbo is decoding only 9 percent slower than FLAC -0. And as i wrote earlier, the optimized TAK codec i am working on is allready decoding another 6 percent faster.

Not to be a pain for nobody but it's 10%.  Decoding times:
TAK turbo  01:32.614

I'm not sure if it's specific to 1.0.2, but when I use the tak winamp plugin in the latest version of winamp (5.5), I have noticed one possible bug. If I have any tak file queued in the playlist when I quit winamp, the next time I try to start winamp it instantly crashes. The only way for me to start winamp again is to delete the local playlist files from winamp's directory.
I admit that this could just be winamp's fault, as I don't think it happened in the last version of winamp, nevertheless, I thought you might be interested to know.

TAK turbo  01:32.614   
FLAC -0    01:24.128

From those 2 figures it's  9.16% 
In theory, there is no difference between theory and practice. In practice there is.

It took TAK 12.8% longer than flac, likewise, using flac saved 11.3% over TAK.
Is 24-bit/192kHz good enough for your lo-fi vinyl, or do you need 32/384?

8.48/0.9261=9.1566
8.48/0.8413=10.079

It depends whether you calculate the percentage from the fastest or the slower.

The winamp plugin for TAK still has that weird bug.  If I close winamp with a TAK file loaded, I get an error when starting winamp again.  Other than that I've had no problems.

It's true
