Asymptotic Manhattan Distance

28 Jun 2026 by phile

Diagonal distance is 141 feet…or should be.

I’m a Logic user but over 10 years ago there was a plugin made for CuBase that introduced noise at -384dB (completely inadiable) which reduced CPU overhead from 40% down to 5%. Good video. As a computer engineer, I just wanted to clarify what subnormal numbers are and how they work. To do that, let’s … Read more

Vacuum Tube (Electron Valve) Comparison Tests

11 Jul 202510 Jul 2025 by sQo

Vacuum Tube (Electron Valve) Comparison Tests The BM Amps “Valve (Tube) Comparison Tests” page presents a detailed, objective analysis of various 12AX7 vacuum tubes used in audio amplifiers. Using controlled signal testing, waveform analysis, and spectral measurements, the author compares tube brands across metrics like gain, noise, distortion (THD/IMD), and microphonics. Despite common beliefs about … Read more

Fractality and Fibonacci

6 Jun 2025 by sQo

Fractality and Fibonacci PROMPT can fractality be explained by the overlapping and/or embedding of fibonacci sequences, the same way to square waves result from added odd-order harmonics onto a fundamental? RESPONSE Yes — that’s an insightful and conceptually rich analogy. Fractality can indeed be modeled or interpreted as resulting from overlapping or embedding of recursive … Read more

How Everyone can hear at least 30 kHz via Square Waves

3 May 2025 by sQo

How Everyone can hear at least 30 kHz via Square Waves Amplify a 10 kHz sine wave. Switch sine to square wave. Stark difference is immediate. Sine-wave fundamental remains. Added are odd-order harmonics of fundamental, first and loudest of which is 30 kHz. The change from sine to square is accomplished by adding onto the … Read more

An examination of how power supply design affects audio circuitry and ultimately sound quality

3 May 20253 May 2025 by sQo

An examination of how power supply design affects audio circuitry and ultimately sound quality Great. I’ll conduct an in-depth investigation into how power supply design affects audio circuitry and ultimately sound quality, considering both objective performance and subjective perception. This will include foundational and recent research, and apply to all categories of audio equipment, from … Read more
