Is there a DIY ADC project?

pixpop · 21st April 2012, 05:23 PM

I need to add some analog input to use when recording LPs and other analog sources to my computer.

Are there any DIY ADC projects, or am I better off just buying a commercial unit?

I bought one of these to do some audio measurements but I note that it also has phono inputs to record from your turntable.

I have a Pearl phono preamp, so I only need line level inputs. Thanks for the info.

If you want real quality you need to look to something at least like E-MU 1212m. It has A/D converter AK5394A.
The SB soundcards have good DAC, but mediocre ADC. I know because I had it and upgraded to E-MU1820m.

I use a zoom H2 - its portable, very good sound quality and fairly cheap. Its very handy to be able to sit it right beside the turntable and not have to either move a PC to be beside it, or vice versa.

It has line level as well. It's a very good unit for the price.

And being battery powered, no worries about common-mode noise from mains

Actually, buying a portable recorder might be the best option. I was thinking about buying one anyway, for another project. Maybe I can kill 2 birds with one stone.

I have a Sony PCM-M10 - a few niggles but generally very happy with it.
