Lossless / Other Codecs / Re: libttaR (TTA rewrite part 2)
Last post by rdtsh -Using (old version) ffmpeg of cli tool for performance comparison is flawed and extremely biased.The tta codec version should be the same between the version I used and the current version, or at least the differences are negligible. You are always welcome to post your own benchmarks.
Also current ffmpeg cli tool have bad performance with smaller packets due to clumsy MT work of ex-developer.ok
Also just to run generic build of ffmpeg for the first time takes extra timeThat cannot be more than a millisecond.
Also this repo does not have any SIMD x86 assembly and the only way performance can go up if compiler is modern clang.If anything, that is a virtue.
FYI, most of the performance increases came from optimizing the rice coder, which is completely unSIMDable

Scientific Discussion / Re: Are complex-input FFTs really useful for audio analysis?
Last post by TF3RDL -For the last sentence can you cite relevant non-pseudo scientific papers?I'll answer this for later (probably if there are either reliable source about this as in my last sentence being cited over or a satisfactory answer that isn't about performance improvements on this miscellaneous reference desk on Wikipedia) as there aren't many non-pseudescientific papers that details the usefulness of complex-valued FFT as in I/Q signals but on audio analysis or even processing stereo audio
BTW, what I call this method a "joint stereo FFT"

Have you watched the attached video from the replay?
It shows you exactly how to move the mouse to the playlist top bar which will display the playlist manager text,
further more it will also show you how to deactivate the auto-hide feature.

Other Lossy Codecs / Re: lossyWAV 1.4.2 Development (was 1.5.0)
Last post by Hakan Abbas -Below is the case where I just halved the block size for mine(HALAC) (from 4096 to 2048). There is an improvement in the results. As I said, in this form, no action is even being taken yet. And unnecessarily fast. The blocks size can be reduced even further, but the amount of data required for entropy encoding is decreasing. This also has a negative effect on compression. It will be more efficient if we group the blocks and put them into coding. And it will also be much more accurate to process as 8 + 8 bits. The only problem for me right now is the processing speed of LossyWav.

Lossless / Other Codecs / Re: Lossless music stores (files!) not offering FLAC, but other lossless compressed?
Last post by Porcus -I see ktf did some research on the actual question.
Honestly, I didn't intend this topic to be read as "this is a bad thing". Actually I am pleased to see that a free and open format has become dominant. I wonder what could have been if a couple of big players had been more successful - one thing is inferior formats, but then it is the scenario that control over the delivery format could make DRM-infestation much easier. Reminder that we still got a bit of intentional crippling in the market (looking at you, scamQA), we could easily have gotten worse.
Sure there are codecs with a multichannel support that FLAC doesn't offer in its own file format, and when 7.1.4 channel 352/24 in WAVE is a full CD-ROM per minute (isn't that closing in on Netflix' HD video?) there could be some savings up for grabs. Technically not too hard to implement, when there are both codecs and containers around.
But with lossless compression having become close-to-synonymous with FLAC except to the apple crowd who might think that "audio" is synonymous to "mp3 or m4a or wav or aif", I have a hunch that a vendor who tried to deliver high-channel files as WavPack would probably regret it after a few days of overworked customer support - even when a self-extracting format was available, just click it then! (Yes SFX was discontinued with WavPack 5, I don't know if anyone has really come to miss it.)

FLAC / Re: FLAC v1.4.x Performance Tests
Last post by Wombat -All i was able to produce with lto and clang produced slower binaries.
I guess some experienced users can do better with lto or pgo or even a combination of both.
