Thanks for an explanations and all the infos.
Hopefully the problem is not complex and can be solved by implementing some new or correcting an existing command or logic. Unfortunately, this does not automatically mean time savings to solve it..
I'm just surprised that this problem hasn't been fixed in the RealNetworks days and has arrived in the year 2024.. unbelievable. Thought i do not know the genesis of this issue, or if there is an encoder version from the past, that downsamples correctly.

I have been looking at this issue after you mentioned the downsampling problem. The sr_convert function only converts 1152 frames of audio data to float as that was what I assumed the encoder eats. But the resampler can consume a lot more data. Perhaps the best solution would be to convert all data to float during read.

your going to hate me i installed new restarted foobar and gas the same playlist manager nothing like the one in your screenshot

i use a trackball mouse

It is not in the playlist manager popup window, but it is in the playlist top bar like shown with the red rectangle in the screenshots...
Go to the playlist ( no top menu button active, if you have a panel button active, i.e Details, Library, Biography, click on it again )
then Shift + right click on a track row for advanced playlist context menu > Panel properties... ( at the bottom ).
Click on the "Export button" and save props.json file and then click on the "Clear button" and OK.

Now the player is using factory settings; you should see text in the playlist top bar if you move your mouse to the red rectangle
area like shown in the screenshots. With default factory settings, the auto-hide feature is enabled, you can disable auto-hide in
top Menu > Options >  Playlist > Playlist manager > Auto-hide.

Please attach your saved props.json file here.

FLAC / Re: FLAC v1.4.x Performance Tests
Last post by jaro1 -
First of all thanks for the binary file, Wombat!
I know this is a discussion primarily about encoder code optimization and not about the features and impact of different compilers on the result, so I don't want to clutter it up with a proxy issue here, sorry for that.
So just in short.. somehow it is going crazy on my side, as i'm unable to reproduce the previous results with same setup anymore.. everything is simply slower today.. anyway, the speed-up from "Release 1.4.3" to last git with GCC14.1 does not seem to happen in case of Clang. Rather your binary has the same encoding performance as NetRanger's Clang binary of "Release 1.4.3", at best.
I've to look, whats wrong here and repeat it later.. There doesn't seem to be any background stuff issue, nor fb2k converter settings impact this.

If i wanted to hear something in shitty, degraded quality for some weird reason i'd use a realtime processing software rather than purposefully storing low-quality files on my disk. What if i wanted to use the high quality original material later?

MP3 - General / Re: Resurrecting/Preserving the Helix MP3 encoder
Last post by maikmerten -
My best guess right now is that there's some kind of memory corruption going on. Float is twice as big as short, so the encoder falling apart in various places (mostly when accessing lookup tables) might indicate that resampling is trampling over memory somewhere.

C be like that.

Lame is a completely different (and more readable, IMO) code base and I don't expect to find something there that applies to the Helix MP3 encoder.

It's theoretically possible to replace the resampler, but one needs to be careful about licensing. The Helix MP3 Encoder has a very exotic open-source license, which *is* recognized as Free Software license, but it makes it quite a bit more complicated to figure out what other code can be legally mixed in.

edit:

Some more digging in, when resampling 44100 to 32000, the resampler can produce vastly "out of bounds" values... just ploppin in a 'printf("u: %f   v: %f\n", u, v);' into Csrc::src_filter_dual_case4 shows that output values can be completely out of whack...

The changelog on your page looks to be Chinese, which I cannot read. Do I oversee something?
The developer is Chinese.  Just copy/paste the log into DeepL; for example the log for 0.5.4.1028 looks like this:

Changes
    Fix the problem that layout modifications do not take effect in real time
    Repair the problem that the search window displays the wrong right-click menu
    Optimize some high DPI related experiences
    Optimize(?) Lyrics search result filtering
    Optimize the display of lyrics processing rules in the context menu.
    Optimize the experience of some settings in Advanced Settings UI
    Add the rule of removing the blank character at the beginning of a line in lyrics content.
