A tool with a very good reputation is Audacity, it's an open source project.
You can choose the input source for recording.
The stream will be stored uncompressed in several small files. This will use much disk space, but is an advantage if you want to edit the sound, e.g. to filter noise.
After the work is done, you can export the whole project as MP3 or ...

I'm not aware of any app meeting all your criteria. There are a variety of "secret video" apps that purport to offer discreet recording, such as Secret Video Recorder HD, but you would probably have to try them to see if they are discreet enough for your needs.
The most difficult criteria you mention is live upload. Video takes up a lot of bandwidth and ...

Assuming that you are using Windows, I personally used CamStudio in the past. It has features such as annotations, watermarks, cursor and other effects, auto pan, etc., and is free to use. It will also allow you to record your microphone.
Just after posting the question, I found them thanks to Archive.org's Wayback Machine:
i can't guarantee that it works with your phone but i guess your best chances would be with Call Recorder from axet.
it has several cool features:

It can record both outgoing and incoming calls. Since Apple got some restrictions for that kind of apps, the recording is archived via merging the calls. It is not free, but worth to try.
I have successfully used it to record the scammers. The ...
If you search using the terms "soundwave art," you'll find a number of programs, both online and offline that will generate images from audio sources.
The result is what could be considered a line graph, in any number of standard image formats.
I opened Audacity, a free audio editing program and loaded Hal9000 saying "I'm sorry, Dave" then chopped it down ...
I use Cubase which is good but not cheap. There are GNU projects trying the FOSS equivalent of Cubase that you can look at. Then you can get a plugin and many effects. I think that your question might be better suited for https://sound.stackexchange.com/
Total Recorder Pro may meet your requirements, although it appears for Windows machines only. Here's one segment of the description to meet your requirement for markers:
Use Cue-sheet files. Total Recorder lets you create cue-points, which can be used for splitting a file afterwards. These cue-points can be created manually, for example to make a bookmark ...
Possible solutions to the above:
i) When the stream contains metadata ( SHOUTcast or Icecast formats ) there is software that can actually leverage this information and chunk up the stream into individual tracks ( example 'streamripper', 'StreamRipStar' ...) complete with artist and title info incorporated into the filenames for each track.
ii) When the ...

sox all_tracks.wav all_tracks-03.wav remix 03
Here's the script from the man page. Pass it the name of the input ...

You can do this with OpenCV in one of several languages but OpenCV 3 has a demo in python called peopledetect.py which would probably be a very good starting point, there are also lots of demos of capturing from the web cam. You could have a modified version of that demo run once every 5 minutes and create a web page with a percentage chance that the room ...
If you are looking to record output audio instead of microphone (basically speaking you asking How to Record the Sound Coming From Your PC)

Then whevever you click the "save replay" button, OBS will save the contents of this memory buffer (the clip ...
