Measurements can explain certain things regarding how an audio component might sound, but to design just around measurements is usually a bad idea. Paul goes into this a bit more deeply.

Beware the measurements

For readers of this blog, it will come as no surprise my thoughts and attitudes on measurements of audio equipment. Yes, measurements are important, but only when in concert with listening—and then too only if you look deep into those measurements to find out how/why what you measure sounds the way it does.

If you’re interested in diving deeper into this subject there’s perhaps no better way than to sit down with an experienced designer and have them take the time to explain how and why measurements simply do not tell you the whole story.

Take for example global feedback in an audio amplifier circuit. If we have an amp circuit with relatively high levels of distortion, we can simply wrap the output back to the circuit’s input and voila! lower distortion. The feedback is a fix-it mechanism correcting for the failings of an amplifier’s design. But at what cost? Nothing in engineering is free. Loads of negative feedback offer low distortion figures but at the same time, harden and constrain the sound. Knowing this is invaluable to a designer who can then ask the question, “what if we don’t have distortion in the first place?”

If you’re interested in diving deep with a designer, here’s your chance. Our own Darren Myers, one of the brightest and best engineers in the industry, spent a good hour and a half with John Darko in a great podcast titled, Beware the Measurements.

Have a listen and enjoy.

Something a little different this morning.

I was contacted by Jean Miller, an editor at Jen Reviews. I am not all that familiar with their website, but it seems to offer opinions on a lot of things, from air filters to sports and fitness to food and many other things.

Jean alerted me to a sister site of theirs that offers a comprehensive guide on jazz standards called Beginner Guitar HQ. It is completely free and you can find it here: https://beginnerguitarhq.com/jazz-standards/.

By virtue of its name, we can deduce that it is geared toward guitar players, so for those of us with no talent to play musical instruments, it may be of limited interest. However, for those that play guitar, perhaps it will be of great interest!
