I’m working on a small fun project (as mentioned in another post).
I imported two musics one about 15 minutes, the other about 30 minutes,
and while editing I turned them into about 5-10 minutes by cutting.
I only used cut, amplify, add silence so far.
Didn’t even try envelope, equalizer, bass boost , etc yet.
Why does Audacity freeze, while playing. This is nonsense.
Does it try to connect to internet? If it connects to internet , or tries to access microphone
in some way, I want to block such possibilities.
You will find that in “Help menu > About Audacity”
I assume that you are aware that version is virtually obsolete?
You’ve not said what you were doing when Audacity froze.
If you were starting or stopping playback or recording, then the problem is probably because of an issue between Audacity and PulseAudio. A workaround to avoid the problem is to bypass PulseAudio by selecting the appropriate “hw” options for recording and playback in the Device Toolbar.
Audacity freezes while editing (and I might be just playing tracks at that time).
I close Audacity by force.
I reopen it, and “recover project”.
And I try to continue editing. But before I even have a chance to edit,
and while playing , it freezes again.
I’m not doing anything with microphone. I don;t want Audacity check out microphone. It must be totally disabled.
How do I do it?
Anyway, I think if I save the project as it is by erasing its past, then I can save on memoery and
continue working safely on it.
So, if I save the project, to be opened later, will the past changes be forgotten, and will
I save on memory usage, and less likely to see frozen Audacity?
I start editing, and at some point, I think all I made is progress, and I don;t want to go back.
But starting from that point, I may go back and forth. SO I want to save the project as it is, forgetting its past.
Do I need to do save project, or mix-render, or will none work?
Audacity is a recording application. It will not work properly unless there is at least one recording device enabled. You may set the “capture” level for all audio devices by using Alsa Mixer (see: Audio/Alsamixer - Ubuntu Wiki and https://linux.die.net/man/1/alsamixer). That will effectively disable the recording devices without interfering with Audacity (though if you wish to use the microphone in the future, you will need to turn the “capture” level back up.)
This is important. Audacity doesn’t record and edit at the same time. Editing can only be done while Audacity is stopped. If the freeze occurs on starting or stopping playback, then it’s probably the PulseAudio issue that I mentioned previously. If Audacity freezes at some other time, then it is not that issue and must be something else.
When I start audacity to recover this project I see a long list of errors on the terminal
:

Also I don’t understand what I need to do to bypass PulseAudio.
I see output device options, and input device options, and they are at default state.
Am I supposed to choose something else for them?
I don’t see anything resembling things on the wikipedia page linked above.

Is there a way I can upgrade to a better version of Audacity, without upgrading to a newer version of Kubuntu?
Those are not actually “errors”. On launch, Audacity has to look to see what audio devices are available. Those messages are just a list of devices that are not available on your system.
There’s no easy way that I would recommend.
The exact steps depend on what audio devices you have.
Open “Audio device info” (it may be in the Audacity “Help” menu)
Wait for the info to appear, then click the “Print” or “OK” button to save the info to a file.
Then attach the file to your reply (see: https://forum.audacityteam.org/t/how-to-attach-files-to-forum-posts/24026/1)
