Recording from more than once microphone in Linux

Would you like to record from two sources, for example a Skype call, to two different files?

Make sure sox is installed, open a terminal:
$ rec -r 44100 -c 1 file1.flac

Open a new terminal tab:
$ rec -r 44100 -c 1 file2.flac

Using "PulseAudio Volume Control" (pavucontrol package), choose Recording tab, select the source for each stream. To record local audio, choose Monitor… 

You can open as many tabs as you like and record from as many sources as you like, if your computer can handle it.

Classical Latin text-to-speech (tts)

To master a language, it is not sufficient to learn to read it well. You must also listen to it spoken. With a dead language like Latin, that means listening to recordings. There are very few audiobooks in Latin, and still less recorded in a decent accent. So I had the idea of making my own using TTS. (Google Translate has a Latin voice, but it's actually just the Italian voice. It's useless for the restored pronunciation. It's not even useful for the ecclesiastical pronunciation of Latin.) The only option for Latin TTS is Espeak . There are two Latin voices available: the standard "la" voice and the "mbrola-la1" voice (you must install the Mbrola voice separately). The standard voice is a drunken robot, very difficult to listen to. The Mbrola voice is much better, but it has a serious incompatibility with Espeak, for which I opened a ticket on Espeak's Github page. I tried using regular expressions to rework the source text (and I discovered th

High-quality audio conferencing

I've tried a lot of videoconferencing programs, including Skype and Hangouts. They all have problems, the most important of which is the crappy sound quality. I was looking for a program that would allow me to make professional-sounding interviews through the Internet. Of course there's always the option of doing a double-ender , but that requires more logistics work and some technical ability on the part of your interviewee. I figured that in the age of broadband Internet, there must be an easy way to do live high-quality audio conferences. After considerable trial and error, I finally found what I was looking for: a videoconferencing program called  Linphone . Here's what makes it so great: It uses the Opus audio codec for amazing crystal-clear audio, far better than any other codec. Skype and Hangouts sound like crap compared to this. (Of course you also need a proper microphone and recording environment.) It allows easy recording in the native format (no tra
