A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...

Sound-level measurements offer a conventional way to measure sound but do not contain frequency information, making it difficult to compare different sounds or vibration. Octave analysis filters the ...

Note: This blog originally appeared on Scope Junction in May 2013. Since then, Octave has seen significant additions in the GUI department (see the blogs referenced at the end), so some of the ...

SBSBRIR is a freely-available binaural room impulse response (BRIR) dataset, measured at the University of Salford’s ITU-R BS.1116-compliant listening room. The dataset includes measurements for 12 ...

[Janis Alnis] wanted to build an analog computer circuit and bought some multiplier chips. The first attempt used apparently fake chips that were prone to overheating. He was able to get it to work ...
