AAC / Re: QAAC on Windows 11
Last post by nu774 -
I couldn't reproduce any significant differences here by SmartScreen.
However, I could observe through Process Monitor the following:
When reading MP3 files, a lot of calls to QueryStandardInformationFile() is issued, at least once prior to ReadFile() each time.
QueryStandardInformationFile() should be expensive on Windows, and this might be the cause.
Simply caching the results on qaac side could make a substantial difference.

Current multi-channel mixing is as follows:
Code: [Select]
uint32_t left_channels = channel_front_left | channel_back_left | channel_front_center_left | channel_side_left | channel_top_front_left | channel_top_back_left;
uint32_t right_channels = channel_front_right | channel_back_right | channel_front_center_right | channel_side_right | channel_top_front_right | channel_top_back_right;
uint32_t center_channels = channel_front_center | channel_lfe | channel_back_center | channel_top_center | channel_top_front_center | channel_top_back_center;
std::array<int8_t, defined_channel_count> mix_factors{0, 0, -3, -10, -3, -3, -6, -6, -6, -3, -3, -6, -3, -6, -3, -3, -6, -3}; // front_left, front_right, front_center, lfe, back_left, back_right, front_center_left, front_center_right, back_center, side_left, side_right, top_center, front_left, front_center, front_right, back_left, back_center, back_right
Left panel gets left and center channels. Right panel right gets right and center channels. The mix factors attenuate center channels by half, generally, since they are mixed into both channels. There are too many channels (18) to intuitively allow for a specific mix factor for each. In case it wasn't obvious, the mix factors are in decibels.

Ah ... i see.
Any chance to expose mix_factors for user adjustments?
Either in config_panel or foobar_advanced_preferences?
Thank you in advance for your consideration.

Hello @oops

If exposing mix_factors for user adjustment is too much work, may I request a special preset?

If (some_flag_in_advanced_preferences)  load
   mix_factors{0, 0, 0, -10, -3, -3, 0, 0, -6, -3, -3, -6, -3, -6, -3, -3, -6, -3};
else load
   default mix_factors;

I hope this is possible. Thank you very much in advance.

On a related topic, may I know why the FC isn't downmixed into the left_channel or right_channel for VU display, instead FCL and FCR is used instead? 
(I would guess that FCL and FCR would be silence in the case of 5.1 or 7.1)

I saw this image in another thread in this forum ... FCL and FCR are not used for downmixing to stereo ... instead FC is used for downmixing to stereo.

Why is it that for videos in the mp4 format, some can be played normally, while for some others, only the sound can be played but the picture cannot be displayed after opening? Are there any solutions to this problem? Or are there any other plugins that can solve this problem?

It certainly sounds like you are using a wrong opus encoder. Load one of the files you converted into foobar2000, open its Properties, then open Details tab, and check the technical field 'Tool' at the bottom. It will tell encoder version information. With the encoder from the Free Encoder Pack the Tool field should show "libopus 1.5.2, libopusenc 0.2.1".

Since you don't seem to have wrong opusenc in the system search path, perhaps you have configured custom encoder paths in foobar's Preferences. Check Preferences -> Advanced -> Tools -> Converter -> Additional command line encoder paths.

Yeah, seems I was a bit hasty with my "problem solved". I momentarily forgot that when I was playing around with the custom decoder settings, I had set the path to some old opusenc.exe file (libopus 1.3, libopusenc 0.2.1) that was in the installation directory of an old version of dbPoweramp which I never got around to paying for an update. So that old one seems to be working but not the one in the f2K folder.

When  I set the custom decoder path back to the encoder from the Free Encoder Pack in the f2K installation folder, it fails again. Back to square one. I am completely stumped.

I have not configured custom encoder paths in foobar's Preferences -> Advanced -> Tools -> Converter -> Additional command line encoder paths. It's empty.

What did you mean by "...in the system search path"? How can I configure this if it might be the culprit?

what kind of lowpass filter is this? is it sharp enough / if you subtract the files one from another, do they cancel out to silence below 20kHz?
I've used the Sox Lowpass filter created by Case for foo2k https://foobar.hyv.fi/?view=foo_dsp_lowpass.
Used settings are: Lowpass: 20000hz, lowpass width: 5%, Phase response: linear
Feel free to create your own lowpassed version using the sample provided by @Teddy_the_barber and compare/nulling it to my lowpass20k.flac sample.

Btw. Yes, they subtract one from another blow 20kHz.

Quote from: magicgoose on
if it is and if there is no clipping involved at any stage, it is very surprising that one can hear a difference above 20kHz.
It's also stange to me, as my hearing stops approximately at 16.5kHz (at insane listening levels).

What's up with automatic updates not working with this component?

the original MIDI  component by Kode54 is named
foo_midi
https://www.foobar2000.org/components/view/foo_midi

on the official Foobar2000 component webpage..
but Pqyt's build based on it is named..
foo_midi+(x64) on the website but named foo_midi on the folder name as to be installed over ins the same place..
https://www.foobar2000.org/components/view/foo_midi+%28x64%29

since its not of the foo_midi main page that is under Kode54's name it won't auto update..
I hope that explanation helps.. lol ;-)
An unfortunate choice at the time but it was my first component.

I want to thank the author for this plugin and  to mention for anyone interested that there is a somewhat hidden function which I always wanted and never knew it existed: If you want search box focus by default when search window pops up, right click title, select "Initial focus to search box".
