General Audio / Re: Standard freqnecy content in high resolution containers?
Last post by rutra80 -
There's no need for anything higher than CDDA spec for listening. Higher bit depths or sample rates may be beneficial in audio processing.

As for video, 10-12 fps doesn't seem right - it might be minimum for perception of motion - below that you'd rather see movement as quick jumpy slideshow...
Framerates over 60Hz mostly help reduce motion blur, which on LCD display is significant even on my 144Hz monitor. Other way to reduce motion blur is strobing (something natural for CRT displays, hence they had nearly no motion blur).

Here's a great webpage with many tests showing these things:

Default: Primay Sound Driver - not bit perfect at all !
Default: RME DAC - not bit perfect at all !
Default: RME DAC (exclusive) - Exclusive output overrides=off Use event=on in Advanced menu (Default foobar options) - very distorted audio!!!
Default: RME DAC (exclusive) - Exclusive output overrides=off Use event=off in Advanced menu - very distorted audio!!!
Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=on in Advanced menu - very distorted audio!!!
Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=off in Advanced menu  16bit output 16bit file - bit perfect 16bit
Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=off in Advanced menu  16bit output 24bit file - bit perfect (but 16bit)
Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=off in Advanced menu  24bit output 24bit file - bit perfect 24bit
Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=off in Advanced menu  24bit output 32bit file - bit perfect (16bit, not 24bit)

Default: RME DAC (exclusive) - Exclusive output overrides=on Use event=off in Advanced menu  32bit output 32bit file - bit perfect 32bit
ASIO: RME DAC - bit perfect (with all samling rates and bitrates)

So there is only 2 good options:
1. ASIO output
2. WASAPI (exclusive) with special settings: 32bit output, Exclusive output overrides=on, Use event=off in Advanced menu


Peter, if it is impossible to fix all exclusive modes, maybe just set my settings in Advanced menu by default in foobar?

I've tested foobar v2.0 for bitperfect playback. RME ADI-2 Pro FS DAC has a special internal test for it, and it shows on display if the output of player is correct or not. All settings are default. Volume is 0dB. I checked all possible combinations with 3 different DACS i have
Maybe it will be useful for somebody.

I am wondering if there is any point in having "standard" frequency audio content in a high resolution containers.

By standard frequency: I am thinking of any thing that could be stored in standard CD resolution, or yet that can be heard ... so frequencies up to 22.05 kHz.

There's no point in ultrasonic frequencies in any audio file, no matter the format.  For audio you only need audio frequencies. ;)  

And there's the possibility of negative side effects with ultrasonic (or subsonic) frequencies but it's usually not a problem.

FLAC / Re: FLAC v1.4.x Performance Tests
Last post by Porcus -
Tested:
30-ish GB of decoded HDCD rips. Yeah I know I shouldn't have made that irreversible mistake fifteen years ago, but here we are.
So these are effectively 17-ish bits in 24 bit container - 95 percent of the tracks have a peak less than .8 scanned with oversampling.

* Why test these? Just to see whether there are any surprises with slightly unusual signals.
* Were there any? Not really. -4 isn't particularly good; I have earlier on questioned whether -5 is really much of an improvement over -4, but here it is. Anyway, that question has probably not made any great impact, I mean who uses -4?

What I did was to re-encode FLAC files (with overwrite) on an SSD. That is why I quote the times per encoded gigabyte. "142" means reference FLAC 1.4.2 Win64, 134 means 1.3.4 Win64, both Xiph builds.
Numbers then. Size relative to 1.4.2 -5, then setting, then comment with time taken. Sizes are file sizes, with tags and default padding.

+1.574%   142-4   ~25 sec per GB (encoded GB).
+0.119%   134-5 
ref.point   142-5   ~30 sec/GB. 31 808 619 711 bytes
-0.255%   134-7 
-0.306%   134-8 
-0.347%   142-7  ~37 sec/GB.
-0.397%   142-8  ~1 minute/GB.
-0.399%   134-8p
-0.412%   142-8e   ~3 minutes/GB.
-0.428%   142-"all the sevens but no p" (see below) - also ~3 minutes/GB.
-0.461%   134-8pe ~20 min/GB.
-0.480%   142-8p 2min40s/GB.
-0.507%   142-8pe Also in the ~20min/GB ballpark
-0.514%   142-"-p all the sevens", about the same time as -8pe

That "all the sevens" - and why not "8"? It is not because it is good! It is because I wanted to come up with a command that was easy to remember, takes about as much time as "-e" and outcompresses -e. Supporting the claim that "-e" should not be used on typical music with normal resolutions: if you are even willing to wait for -e, then there are better things around. (It is known that -e still has something for it on higher sampling rates, potentially.)
The actual option line is -7r7 -A "flattop;gauss(7e-2);tukey(7e-1);subdivide_tukey(7)" with an additional "-p" for the last line. And a -f to overwrite, but that goes for everything.
For those who ask "why -7 and not -8"? It wouldn't make any difference, -8 is -7 with a different (and heavier) "-A", and the moment I write "-A" here I override that by specifying yet a different (and heavier!!) -A.

Did you really type "flatopp"?
Damn, only one way to find out, and that is not done in two minutes ...
Here I made sure to get it right!  O:)

But anyway, bottom line is what we knew, 1.4.x improves, and -e does not deliver at these resolutions. -p is nearly as expensive, but much better

General - (fb2k) / Re: ReFacets
Last post by Erich_2 -
My folders on the SSD are sorted by C:\Music - MusicType - RoughGenre - Artist - Album - Title.
in MediaLibrary: C:\Users\MyNAME\Music\MusicType\

RoughGenre is AustoPop, BluesRock, Rock, Country, Guitar, Jazz, Klassik, R&B and so on.

In Facets I used Folder = $directory(%path%)
I use two ore sometimes three times „Folder“ and then Album and so on...
The first 2 (or even 3) columns work perfectly with my folder structure: (Just like on SSD)

Till beta 26 ReFacets Folder = $directory(%path%) didn’t work anymore
I used Folders with „SpecialFolder“ as a workaround:
SpecialFolder = $directory(%path%,$sub($len(%path%),$len($replace(%path%,\,,|,,/,)),N))
N= 2,3,4,5,6 or 7

But in ReFacets (beta 27 and 28)
is „Folder“ a total disaster:  (Folder = $directory(%path%)
My special Workaround  SpecialFolder = $directory(%path%,$sub($len(%path%),$len($replace(%path%,\,,|,,/,)),N))
doesn’t work anymore, shows pointless or a mix of folders and albums.

What’s going on with ReFacets when using Folders?
And yes, simple Genre - Artist - Album - etc. works.
But I don‘t want to see 1000 Genres with special-SubGenres  in the first Column!!!

I went back to Facets.

Hi guys :) I had lost track of this topic. Since nobody seemed interested at the time, I had stopped reading it.

@marc2k3 , I'm really glad you came up with a solution. It seems like requesting it at Christmas was a good idea after all  :P

That is exactly what many of us were looking for. It's of course up to you to share it or not. Just let us know! :D

3rd Party Plugins - (fb2k) / Re: Playlist Organizer (aka foo_plorg) replacement on Jscript Panel 3
Last post by etip -
ok, i should have specified it but the size and style is not affected, only the font name will change.
You can however change size in the panel as well as the style (only for folder).
Frankly, i dont know what's happening as it works ok for me. i cant help but notice a playlist which is an icon (the magnifyer icon). Can you try to rename it to a text ?
thanks

do you use the default User Interface (DUI) or the Custom User Interface (CUI) ?
On CUI (my foobar), it is :
X
then choose custom to change font:
X
Click the "change" button and choose a font. When you click ok on that same window, the panel should update as it is a callback i'm using (on_font_changed)

This example is about the font change of the label item ie on the panel the folder, using CUI.
