3rd Party Plugins - (fb2k) / Re: UPnP: How does the Media Library Tree work?
Last post by SimBun -
Is there another UPnP component that allows this much control over the Media Library Tree?
I guess it depends what your requirements are, as foo_upnp benefits hugely from having foobar as the backend e.g. the ability to handle CUE sheets, the playlist functionality e.t.c.

I use the licensed version of MinimServer on a Pi and I think it's just as flexible as foo_upnp (in terms of presentation). There's also AssetUPnP which does a few things differently to MinimServer, but I prefer MinimServer overall.

If you have anything specific you're looking for let me know.

Opus / Re: xHE-AAC : The Death of OPUS?
Last post by ktf -
I agree. That reply was in the context of using lossy codecs at high bitrates to encode music to achieve transparency for all possible inputs. It seems there is little room for improvement there. At the bottom end, there are still lots of opportunities.

Opus / Opus .ogg vs .mp4 container?
Last post by Marsu42 -
Opus inside mp4 seems improving - here's qaac support https://github.com/nu774/qaac/commit/8c8dcfc7b3977f9419d059c32463213966c98dcb

I've been using both the ogg (for opus) and mp4 container (for aac) and the corresponding tools opusenc/opustags, mp4box. For my simple offiine encoding and tagging purposes, playing on mobile devices both seem to be sufficient - actually, gpac is a bit feature overkill.

Except for app support, is there a significant difference between these containers for an opus stream?

I'm just wondering and want to start a standards flame war - so please be kind :-)

Support - (fb2k) / FB2K 2.2 preview - Opus 1.5 LACE/NoLACE, DRED decoding?
Last post by Marsu42 -
The preview changelog 2024-03-08 states "Opus decoder updated to 1.5.1" https://www.foobar2000.org/changelog-win-2.2-preview

Opus 1.5 includes a new decoding feature (LACE/NoLACE) which is a postprocessing filter: https://opus-codec.org/demo/opus-1.5

However, the complexity on DECODING neets to be set to enable these - see https://hydrogenaud.io/index.php?topic=125597.msg1041651#msg1041651

There  now is a opusdec exe with the complexity set - see https://hydrogenaud.io/index.php/topic,125597.msg1041927.html#msg1041927

=> Does the libopus library in Foobar 2000 have this set to enable LACE/NoLACE decoding, and would you add an advanced option to set the decoder complexity (6 for LACE, 7+ for NoLACE)? Edit 1: This affects decoding the new DRED feature, too.

Edit 2: This is how qaac does it: https://github.com/nu774/qaac/commit/4770366db1ad632a2d21fdb5992331d8c8733e84

General Audio / Re: How do you test SACD audio dynamic range?
Last post by clintb -
I extract SACD ISO to .dsf then compress with WavPack in DSD mode. That goes into 32 bit foobar and is RG scanned and DR scanned. I don't use the DR component for a truthful indication of dynamic range; it's to get a sense of whether or not a particular release is similar or exact match to another.

Opus / Re: Opus gapless and glitchness encoding
Last post by Marsu42 -
Err, more than three years have passed.
Proof of concept by @Octocontrabass makes it gapless, official Opusenc does not.
How to get the case off the ground?

Is there a directly correspeonding bug ticket or feature request on gitgub for libopus or opustools?

I don't see anything except this one, last reply in 2020 - maybe the title "Pre-skip doesn't include extra_samples" isn't very inspiring to work on it :-) https://github.com/xiph/opus-tools/issues/55#issuecomment-641603262

The gist is that with opusenc you're out of luck except for a rather major change to encode multiple tracks at once - personally, I'm sometimes confused by features of libopus (in active development) and opus-tools (nearly no development anymore).
