One of the challenges is the multiplicity of sounddrivers\/sound servers.
\nAlsa – OSS- ESD -> and to make stuff more complex, I use an external soundcard..
\nHere is where you find the sound preferences of your Linux computer through the graphical interface (by using your mouse (^_^).<\/p>\n
This is what I can choose from: Now, as I try to work with a script, I need the command line version of this: This command displays all soundcards and digital devices that can be used to capture sound – at that moment:<\/p>\n $ arecord -l<\/p><\/blockquote>\n On my computer I get a result indicating that my soundcard of my laptop is hardware device number 0 for capturing and the external soundcard (USB) is hardware device number 2:<\/p>\n $ arecord -l Now, I want to record a test sound through my external soundcard, via arecord (in the Terminal).<\/p>\n $ arecord -f dat -d 20 -D hw:1,1 test.wav<\/p><\/blockquote>\n The sound is recorded in the file where you are on that moment in your Terminal.<\/p>\n *Extra* – To see which soundcard(s) are installed on your computer:<\/p>\n $ cat \/proc\/asound\/cards<\/p><\/blockquote>\n – To check what sound modules are loaded:<\/p>\n $ cat \/proc\/modules|grep snd<\/p><\/blockquote>\n Thanks to linuxquestions.org<\/a> and Cyberciti.biz<\/a> for the online inspiration. <\/p>\n","protected":false},"excerpt":{"rendered":" I have recently been working on a manual for a certain script with which you can easily record interviews, without having to edit them.
