Analog to Digital Converter Test

This is a repost. Article was in another location on the site

In August, 2007 at The Banff Centre I recorded a classical concert through two Schoeps MK-2 omnis through a Millennia preamp, then split the signal into 5 different analog to digital converters and recorded. While I would not call this an error-proof science experiment, it does provide a solid demonstration between various levels/prices of converters.

The Meitner and Lavry converters are the more expensive, followed by the multitrack Radar built-in A/Ds, and concluding with the Digi 002. I also included my Apple Powerbook G4 line-in as the extreme opposite.

The musical content was only piano and a brass quartet. Ideally an instrument with a greater dynamic and frequency range, such as a drumset or percussion ensemble would have been wonderful.

Noise

This first example demonstrates the most obvious differences between converters; the high end. These short clips are of the pause in between a movement of music when the musicians break for a moment, and the hall is the most quiet. The clips are turned up about 30dB, but I assure you there's no loud noises.

Music Content

Musical passage example.

The first set of clips do not have the 002 yet.
