I've been playing about with recording sound, with mixed success at first. I was trying to record from cassette tapes, but when I hooked the amplifier output up to the Line In plug on the sound card, I got only silence. If I used the Microphone input, I could record stuff, but it had quite audible distortion.
I noticed that Mike Holland had the same problem: > On Tue, 24 Jul 2001, Matthew Dalton wrote: > > > Anyone recording it? > > I'll give it a go (2hr delay here). 2:15pm?

Setting Line to Record still resulted in a recording of silence. Somehow it seemed to make more sense when running the gtk interface to aumix. (Note: even if you compile this up with gtk enabled, the only way I discovered to make it start up with gtk is by linking aumix to gtkaumix. That wasn't mentioned in any of the doco I could find. The man page implied it would do this if started up with DISPLAY set, but that was certainly not the case for me.) Anyway, by setting the Record option onto Line in the Gtk interface, I'm recording happily now. And the quality is much better. Very little distortion. Slug comes through with the goods again! And I'm sure that this will sound really obvious, but you can check what you've recorded very conveniently if you stop the recording, turn the volume right down on Line, and then play the sound back. This is much better than getting up and walking across the room to the cassette deck and hitting Pause or Stop. :-) luke -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
