Use faster CRC16 algorithm to speed up encoding/decoding for CUETools possibel?

2019-01-15 10:08:07

Hello,

first, thanks to the developers of the great CUETools and Enzo for the faster CRC patch.

Since the last CUETools version is out for quite a while, I have a question what you think about implementing a faster CRC16 algorithm?

I like to ask you developers, to have a look into those CRC patches:

https://hydrogenaud.io/index.php/topic,115900.0.html

https://github.com/mattsta/crcspeed

https://github.com/xiph/flac/pull/57

https://github.com/xiph/ogg/pull/37

I think, that would be a nice improvement.

Thank you in advance.

Greetings

Just had a quick look at the CUETools source and it should definitely be possible to speed up the CRC16 and CRC32 calculations using the same method I used for FLAC and Ogg.

Another question is how much this would affect overall speed of CUETools workflows (i.e. how much time is currently spent for CRC calculations vs. other things), but I guess it might be worthwhile.

Would be great if the CUETools developers could look into it.

@hydrogenaudio0815: Maybe you should open a feature request at https://github.com/gchudov/cuetools.net/issues. Your post might be overlooked easily here.
