Further (mis)adventures in measuring audio equipment

Posted on 4 October 20214 October 2021

The most visited page on this site has always been the guide to distortion measurements, written when I had just discovered the thread on DIYAudio. That post, like many of my other posts here, was written more as a reference for me and this one fulfils much the same function. If it’s of use to…

A quick note on distortion

Posted on 27 December 201929 January 2020

Recently I built the Nelson Pass H2 Harmonic Generator, a circuit that injects some 2nd harmonic distortion into the signal chain. Whilst I still need to get this boxed up to play with it properly, I’ve been mooching around and doing some reading on distortion. As part of my meandering, I came across this website…

A DIY approach to distortion measurements for audio amplifiers

Posted on 1 September 201911 November 2021

I imagine I am typical of many DIY audio enthusiasts in that I build something and hope that subjectively it sounds good. However, I am also curious about the objective measurements of the equipment.

For measured, thoughtful thinking of topics relating to computer based audio (including measurements), have a read of Archimago’s Musings. For questions, discussion and often…

Two tracks from this recent CD on ECM by the Tunisian oud master together with Django Bates, Dave Holland and Jack DeJohnette.

Musicscope Analysis: Gogo Penguin – A Humdrum Star

Posted on 16 February 201825 June 2019

I thought I would start posting Musicsope analysis data from recent music purchases.  The results are presented without comment: dynamic range (DR), loudness levels, pushing levels to clipping – all are artistic choices. For the most part, it’s not my cup of tea to have such restricted DR but then again, I don’t suppose I’m…

Is it real or is it……

Posted on 15 February 201825 June 2019

In the 1970s Memorex ran  TV adverts that attempted to show how people would not be able to tell the difference between a live recording and one that was recorded to their cassette tape. The tagline was: Is it live or is it Memorex? Now we are told that 16/44.1 music is not really good…
