Local audio recording to boost the audio quality for asterisk recording

November 23, 2008

I’ve written a Howto for recording a podcast with asterisk. This setup is working for our podcast (in German) for some time now, but we wanted to boost our audio quality over the codecs quality asterisk supports. For this we use arecord, a command-line sound recorder for the ALSA soundcard driver, to record locally under Linux. So we use asterisk to talk with each other but normally we use the locally “with CD quality” recorded files for the podcast. The Asterisk recorded stuff is used as backup, as it happened already once that one lost his local recording. 😉
