FLAC / Re: Retune of FLAC compression levels
Last post by Porcus -
Can those who run tests please let us know their CPUs?

Asking because there are known differences between Intel and AMD processors. For example, in ktf's tests (using an 1.3 version), -3 seems to be the fastest decoding, and that seems to be an AMD specific thing. More differences got known as HA users tested 1.4.x performances.

Short "just a couple of files" testing here, will do more when I am back to my test corpus at my computer (which BTW is now running a re-encode to 1.4.2 on a hard drive which is nearly full - that's when 50 cents of hard drive space is worth a bit more):

* Going full -l32 on high sampling rates:
My first reaction was, this will shock those who use "-8e", I checked one high-resolution file that now takes 4x the time of 1.4.2. That is even if the reduced number of apodization functions speeds up -8el12 to half the time of 1.4.2.

But the thing is, -e still has a mission on some high sampling rates, that is the problem. At least it had on 1.4.2, I'll test this one.
If there is a way to get a more clever semi-exhausting that tries the right thing, then maybe change the meaning of "-e"? (And introduce a "-E" for "YES I have the patience".)

* -0 with stereo decorrelation:
You probably thought over the following scenario, but ... what if somebody runs an on-the-fly encoding with a decoder that can only do dual mono? (I guess they won't use a new flac.exe anyway.) And 16 bit word length (cf. the limitations you put on 32-bit signals) - would anyone want dual mono as a point in itself? If so, they might specifically have chosen a preset that does dual mono.
If - and that's a big "if" - there is a point to have a dual mono preset, then what else than -0? 

* Going full 4096 is probably not a bad idea. Will test. Did test on 1.4.2, with some slight surprises. One was a penalty for 4096 over 3172.

(* Will test: Old -6 as new -5? I've argued that -6 wasn't much useful except for those who wanted the lightweight decoding of -l 8. Will test.)

* A_Man_Eating_Duck certainly has a point. I would ask how many use anything but -0, -5, -8, -8withsomeadditionaltweaks, but actually Bandcamp uses -6 ... which I've said bad things about. But hey, as long as there are -1/-2/-3/-4/-6/-7 around already, it doesn't hurt to give them some sensible meaning. (If that's a solution looking for a problem, then the problem was set up twenty years ago.)

New version :
Playlist Organizer (Jscript Panel 3)
v1.6.0
28-03-2023

Version changes :
- font size starts at 9
- Color of the line separating the header from the list can be customized.
- fix crash when right clicking at load up
- implemented a search functionality : Triggering it using shift, closing it using shift again. Search starts at the third character.
@frogworth : let me know what you think and how to improve it (i need to make sure the scroll goes to the selected item).

The files "inputbox.js" & "pl_organizer.js" need to be copied in the pl_organizer folder (the inputbox.js file is new and was developped by @marc2k3 )

FLAC / Re: Retune of FLAC compression levels
Last post by john33 -
I have to say that I rather think that this is a solution looking for a problem. The majority of users will simply use the default preset and most won't venture beyond that. For those few enthusiasts who wish to delve into the depths of what is possible, no doubt they enjoy playing with all the various current options. I'm not saying it's a bad idea, I'm just suggesting that it's not necessarily relevant.

Sorry a bit of a newb question but does FLAC need to have 8 different preset levels?
It probably doesn't need to, but it seems most people like some choice. TAK has 15 presets, WavPack has 4 presets and 6 different modes of extra processing (which can be combined in any way), Monkey's audio has 5 presets and OptimFROG has 12. So, FLAC isn't alone in this regard.

A quick test on my CDDA material shows a 26.5% decrease in encoding time and a 0.07% increase in filesize for flac -8 with this patch applied.
Did you compare against unpatched current git, the latest release (1.4.2) or something else?

Changing the number of presets would break old FLAC frontends, which ktf probably doesn't want to do. It's cleaner to rebalance the existing nine levels than to change the number of levels.

- I don't really have an opinion on how it behaves if a folder is closed. I generally always have folders open. My instinct is that playlists inside closed folders should not be included, but I'm not set on that.

I've started to work on it, the idea is to push (and stay pushed) shift to input chars, if you release shift the process stops. At each char (maybe with a min of 3), if a playlist matches, it selects it. Something like it.
And yes, i will not open folders.
Thanks for your answer.

FLAC / Re: Retune of FLAC compression levels

Sorry a bit of a newb question but does FLAC need to have 8 different preset levels?

Could it be broken down to a more simple scheme?

Preset Fast = FLAC preset 2
Preset Medium = FLAC preset 5
Preset Best = FLAC  preset 8

or

FLAC preset 0,1 get mapped to Flac preset 2
FLAC preset 3,4 get mapped to Flac preset 5
FLAC preset 6,7 get mapped to Flac preset 8
