Opus / Re: Opus gapless and glitchness encoding
Last post by jmvalin -
There's actually a library (libopusenc) that can do sample-accurate perfect glitchless (you could split a song in 1 millisecond chunks and still not hear anything wrong), but right now I'm not aware of a tool using it.

Thank you kindly for the explanatory and rapid reply E. Sokol!

In first versions i made a support of second sub with independent delay and volume, but remove it later. Two reasons: it make using of plugin harder and no one use it. I plan to make independent plugin for this at future, if anybody need it. You can use Matrix Mixer (or some another) yet.

Yes, please do. Bring it back!! I need it!! I use my dual "subs" up to ca 300 Hz and they will need individual alignment with the main speakers. There are other benefits of dual subs, for example when used with room correction software, they can be used to lift the dips in the response, that occur (not the way I have set them up, just to highlight other benefits of multiple subs).

I take the opportunity to return to the stereo question. Since this is built on LFE concept, doest that mean that stereo cannot be created in the dual sub independent plugin?

Thank you also for the Matrix Mixer link. I'll check it out.

I will be eagerly waiting for the dual sub independent plugin!!

Thank you again!

Opus / Re: Opus gapless and glitchness encoding

Am I really the only one having this issue ? Or maybe caring about it ?
I also found that opus can add audible glitch between gapless tracks. Even if files are resampled to 48 kHz before encoding. Also there is highpass filter. I never tried to split opus files.
Here  are samples (In this case files were not resampled to 48 kHz before encoding to opus).
File "Image.wav": source files encoded to opus (1.3-rc-1, --bitrate 256), then opus files are decoded by foobar2000 and merged
File "Image sox.wav": source files were merged, then resampled to 48 kHz by foobar2000 with SoX resampler plugin.
Source files and opus files are also included.

Opus / Re: Opus 1.3-rc2
Last post by jmvalin -
When  final release will be ready?    O:)  ( joking)

Actually, the only reason this release was called -rc2 instead of 1.3 is that we've enabled a few things by default (delayed decision, extra checks, ...) and wanted to make sure they're not broken. The final 1.3 will be out as soon as we're confident enough that there's nothing bad in -rc2.

@musicmusic : Thanks for all the work on CUI! I've tried using the latest v1.0.0 version and wanted to share a bit of feedback - in the preferences menu there a lot of space taken by the sub-headers on the page and a lot of unused space in general.

Most obvious example is the Layout page:
Spoiler (click to show/hide)
- A lot of space is taken by the "Layout" text, which could be otherwise used for displaying the layout tree.
- A lot of empty space is on the right side of the layout tree (i.e. where all checkboxes are): the checkboxes could be safely moved further on the right.
Is that your actual layout? I would expect that pushing those controls further to the right would move them further away from the items in the tree view for the majority of people, which wouldn't help usability. The layout tree view is actually slightly larger than it was in previous versions, if you still need a bigger one I'd argue that the best way to achieve that would be a resizeable preferences window (although, I accept the chances of that happening for the preferences window managed by the foobar2000 core are slim...)

And a small suggestion: is it possible to add ability to mark panels with labels in the layout tree (e.g. "Panel Stack Splitter (Library Switcher)", or "JScript Panel (Menu)")? It's getting a bit hard to organize the panels when there are a lot of them, and all their displayed names are the same...
I could make it display a custom title instead if one is set. (Not all splitters support custom titles for contained items, though.)

Opus / Re: Opus gapless and glitchness encoding
Last post by ofboir -
Hi

Thank you lvqcl for your answer !

I tried what you suggested, but it doesn't seem to work :
If I split a temporary 48kHz file, I get a bad splitting (doesn't correspond to actual tracks). I got this by splitting to flac files, or directly to opus files with on-the-fly encoding. I used shnsplit for this.

I also tried to directly cut a single 44.1kHz flac file to opus files (again with on-the-fly encoding) : the splitting is correct, but I still get the glitch !

I should try to cut opus file after encoding with ffmpeg (like suggested by the post you mentioned), but how could I do this using a cue sheet ?
One other thing : how could I transfer tags from my initial flac files to the final opus files ? I loose them as soon as I create a single file ...

I am really starting to think I will give up with Opus. Am I really the only one having this issue ? Or maybe caring about it ?

Thanks
