Lossless / Other Codecs / Re: Lossless codec comparison - part 3: CDDA (May '22)

Correction to my eyeballing:

TAK -p4m outcompresses Monkey's Insane - by 108 parts per million, that is such a small margin that had it been the other way around, it could maybe/maybe not be tilted by the already-published TAK 2.3.2.

Since I was too curious (and at the risk of posting wrong numbers - @ktf, are they correct?), here are the compression percentages around where we enter the LAnd of FROG:
50.39 OFR --preset 1
49.72 Monkey's Extra High
49.68 TAK -p4
49.66 OFR --preset 2 <-- default!
49.64 TAK -p4e
49.59 Monkey's Insane
49.58 TAK -p4m <-- 108 parts per million below Monkey's Insane
49.39 MPEG-4 ALS -7 <-- making ALS the highest-compressing ffmpeg-decodable codec
48.58 OFR --preset 3 <-- this isn't in line with eyeballing the plot vs ALS -7. Triangles vs circles seem to make for an optical illusion here, or did I get the numbers wrong?

The corpus this time is quite different, obviously. I'd be surprised if a "popularity-weighted" compression ratio is 0.5.

3rd Party Plugins - (fb2k) / Re: JScript Panel
Last post by marc2k3 -
I've been setting a bad example in my own scripts by not checking the src width/height before drawing but the only way that could happen was if they were calculated from the panel width/height which would have to be zero and therefore not visible. Default UI won't even let you resize that low but I guess it's possible with Columns/Panel Stack Splitter.

Setting these args as zero when the panel has proper dimensions and is visible is just really stupid. If calling the function succeeded, what exactly do you expect to see??

I really hate doing it but I've updated the function to silently bail if the src w/h are bad,

https://github.com/marc2k3/jscript-panel/releases

edit: the difference in behaviour between v3 and previous versions is because I'm using Direct2D instead of Gdiplus. Gdiplus was generally very tolerant of bad args everywhere but it seems more care is needed now. I already have special conditions in place where drawing text isn't even attempted if the width/height are less than 12px. I discovered this quite early on in my testing!

After an install on the new computer, you can try to copy the c:\program files (x86)\foobar2000 folder and the %appdata%\foobar2000 folder over to the new computer. For the latter, you can either access it from within foobar2000 by Alt+Shift+F b - or from the OS by presseing the windows logo key, typing %appdata% and hitting enter.

At worst you will have to delete stuff from your new computer and try over.

General - (fb2k) / I moved computers. How do I get my original foobar2000 customized interface?
Last post by kvhpkh -
 I recently moved into a different computer and even though I backed up all of my foobar2000 files, the external hard drive will not copy programs to the new computer.  I'm told this is a Windows thing.  So, my foobar2000 is not customized to the way that I had it.  Is there a way to retrieve that?  Is it stored in the cloud somewhere?  Or, what is the name of the folder/file that keeps that information?

Lossless / Other Codecs / Re: Lossless codec comparison - part 3: CDDA (May '22)

You are right, I could have made that more clear. The software used for timing returns two values: CPU time and real time (wall clock time). These always differ by a little, I'm not sure how it is possible the wall clock time is sometimes shorter than the CPU-time, I guess that it is caused by some inaccuracy of the timing method.
Thanks, that makes sense.

Seems to be copy-pasted from hi-res comparison and doesn't apply to CDDA.

Shouldn't the resulting filesize be recorded after encoding, rather than decoding?
Thanks, fixed.

I also have a question about the CSV file.  Fields 1-3 and 8 are obvious.  Fields 4-5 seem to represent encoding speed (i.e. reciprocal of cpu-usage) and fields 6-7 seem to represent decoding speed.  But what is the significance of each pair?  Are they just two separate runs?  Does one give average speed and the other the reciprocal of average cpu-usage?  Or something else?

For the graphs I've only used the first of each pair, which is CPU-time, which I deemed more accurate. I left the PC idle except for running the tests, no network connections were active, anti-virus was shut down and only 1 of the 4 cores was used, so the values shouldn't differ much.

edit: I say CPU-time and wall time, but it's actually audio length  divided by either CPU-time or wall-time. In previous comparisons I used to express speed as 'times realtime', and this is still how the script works. Only during graphing this is inverted to 'percentage of CPU used'
