Measurements of DACs, CD players and computers

[Patrick Harper]

This is a bit different to most measurements on this forum as they were done for a dissertation in pursuit of a BSc in audio engineering. Skip to page 11 to avoid the fluff. I used other contributed measurements to aid in my...'analysis'.

Reviewing this and the poster hurts me a little because I know what I was like while I was making this. Being trained to have a mechanistic view of the world has a social cost. But in an objective sense I don't think the content is harmful.

Thanks for sharing. Would you do it differently today?

I believe digital audio has been a solved problem since dithering and noise shaping was devised to preserve dynamic range during reduction from 24-bit to 16-bit quantisation, and DSD64 managed to achieve marginally favourable performance from particular hardware designs. The applications for this type of research are limited in my opinion. I knew this at the time but I was short of ideas.
