Hi, I have a cube (030 with 1.0 OS) and I am interested in doing some recordings from CDs to create some snd files. I have tried using the mike input but the background noise is quite high. I wonder if there are alternate ways of making snd files from external CD sources. (I have also try going from the CD output jack directly into the mike input jack but the quality if still bad. I suspect I have some impedence problems here). I would appreciate any suggestion your guys may have. Thank you. Lue

The CD goes at about 44K. (Higher is better. Lots better. Also, the bits per sample is at best half.) The best way of making .snd files would be to take a digital out from a CD player into the NeXT via some port. I don't think anybody's doing this (yet). What some people are doing is releasing products to interface with the DSP to allow recording at CD quality. I know of two: Digital Ears from Metaresearch (though I'm still annoyed with them because their software won't work under 2.0... I know they're working on it.) And the Digital Mic from Ariel. The Digital Mic includes a real microphone as well as line inputs; the Digital Ears has only the line inputs. (Sorry I don't have prices... I live in a blissful undergraduate world in academia where I don't have to worry about equipment costs... which is just as well because I couldn't afford it. Oops ... Bandwidth alert.) I suppose I should mention that I have no connection with either company (well, I'd love to keep using our Digital Ears if I could get working software!) and that if you record CDs in any way, you're probably breaking copyright laws. But lots of people sampled Phil Collin's gated snare reverb...
