FLAC / Re: FLAC v1.4.x Performance Tests
Last post by Porcus -
-5p from 105 to 36 seconds ...  ;D
I didn't quite get the change, but is it so that the code checks that the residual fits a signed short, and when it does ... much faster?
Has it made changes as to when it can select the 4-bit method?

How does -5e work? And with sizes for -5, -5e, -5p? Never mind whether there is any change in -5e, I am curious about the bang for the buck, and the comparison between -5e and -5p must have been tilted right now.

FLAC / Re: FLAC encoder for arm cortex m4f with limited memory
Last post by bryant -
Unless your tied to FLAC, WavPack might work for you. I created a tiny encoder a long time ago that should still be usable. It's used in Rockbox to this day (in fact I may have created it for that application) and encodes CD quality on far slower ARM processors than yours.

If that's still too much (the tiny encoder uses about 100 KBytes or so for code and data) I created another lossless compressor called SLAC that is very lightweight. The disadvantage of that is the files are not compatible with anything (there's not even really a file format, per se) but depending on your application that might not be an issue (it's lossless, so conversion could be done later off your device to something universal).

FLAC / Re: FLAC encoder for arm cortex m4f with limited memory

There are a lot of FLAC decoders available, but only a few encoders.

How have you tried to get the reference encoder working? It is possible to strip quite a lot of parts, maybe that way it'll fit? Stripping the floating point parts is going to save a lot of memory for example.

I just wanted to say thank you for this effort and time. Thanks to you, I am now able to upgrade to X64 foobar.
 ;)

My most sincere thanks for this altruistic gift you shared with all of us.
