followup question: recording audio and volume
I've been using ubuntu to record some screencasts (kinda. Khan-style lectures, really)
I want to know what is the volume setting for the microphone for optimal results.
I am guessing that "base" (in pavucontrol) or "unamplified" (in the ubuntu volume control) , and increasing the volume later in ffmpeg would be optimal for quality (as compared to just using a higher setting)
Is that true ?
Bonus points: are "base" and "unamplified" the same ? What does the "100%" setting in ubuntu volume control means, given that it is different than "unamplified" ?
