Any change in major or minor number indicates a new release branch. And the convention since 5.0 has been to go 0 --> 1 --> 0 --> 1 ... for each new branch.

What happened is that as the corpus of useful info increased, the need to pose new Qs decreased. AI much accelerated that decline by making available an 'oracle' trained on that corpus.

What will you do for ice cream then?

It can be done in a single command, no temp files needed.

https://huggingface.co/sarvamai

The orig wants a mono output with one of the original channels as signal source. This involves downmixing i.e. rematrixing the audio.

The dupe want to just mute one of the channels, not repan it. One can't apply map_channel to do what the dupe wants.

One can use a couple of methods to achieve the dupe, including pan. But the syntax of pan needed for the dupe case is not the same as the orig, or deducible from it. They need to consult the docs (fortuitously, the dupe case is an illustrated example) or get a direct answer. The 'technique' shown in the orig is not intuitively adaptable to the dupe - one needs to know about the implicit muting that pan applies, which is not documented or evident in the orig answer. So it's not a duplicate of the source Q.

I answer Qs on this topic, not post them.

----

Here's an example I found:

https://superuser.com/questions/1929615/ (the canonical q is about extracting as mono, the closed q is about muting one channel)

How do I search for Qs closed as duplicates with a certain tag?

That's not the case. As a maintainer of a popular project who has engaged with thousands of Qs on SO related to that project, I've seen many Qs marked as duplicate where the actual answer would be different in a non-trivial manner. When I look at who all moderated on those Qs, they are usually users who haven't contributed to that topic at SO.
