| In April 2000, Elektor presented a Voice Shifter project to demonstrate how a handful of analog building blocks can dramatically alter speec...
| Hum can ruin great audio just as effectively as noise. In this article, we take a closer look at the theory behind hum and how to eliminate...
| Can a handful of transistors outperform a microcontroller? This acoustic sensor delivers reliable, fail-safe sound detection and shows how e...
| Although the audio spectrum ranges from 20 Hz to 20 kHz, it is sometimes advisable to narrow it at the low end to avoid issues at the beginn...
| The T-Reg high-voltage regulator circuit delivers clean, stable power for tube amps. Supporting output voltages up to 500 V, you can use the...
| Online music collaboration is difficult due to latency, and common platforms fall short. This audio latency measurement project features an...
| Mains hum from loudspeakers isn’t always caused by bad wiring, poor cables, interference, or grounding issues. Sometimes the amplifier power...
| Audio notch filters are useful when an engineer needs to see low-level harmonic distortion that would otherwise be buried under a much large...
| Professional audio systems often use fully differential signal chains — from inputs and outputs to ADCs, DACs, and filtering stages — to ach...
