Generating a linear fade in of length T for a signal happens by multiplying the signal with function f(t) = k*t, t ∈ [0, T] f(t) = 0, t < 0 f(t) = 1, t > T where k is the inverse of the length of the fade in (k = 1/T) and at the starting point of the fade in t = 0. Logarithmic fade in/out...

Whenever I listen to a binaural recordings, I get a similar feeling of coldness as if I was listening to the sounds in a cold environment. Today it came to me. It all makes sense now! My head is rather small. The dummy heads used to create the binaural recordings are probably larger than my own...

When I studied spatial hearing in university back in the 90's I was though Interaural Time Difference ITD to be ITD = r/c * (sin 𝜃 + 𝜃), where 𝜃 is the azimuth angle of sound, r is the radius of a rigid ball approximating head and c is the speed of sound. This formula is by Woodworth (1938)...

The limits of amplitude panoration Traditional amplitude panoration isn't perfect, but works relatively well with speakers. With headphones this approach results quite unnatural spatiality. So, how should panning for headphones (HPAN) be? ILD (Interaural Level Difference) HRTF-measurements...

Headphones and monophonic sound Inspired by the discussion with Bigshot on another thread about historical recordings, I took Furtwängler's Beethoven 9 from 1952 as a casestudy. It is a great performance, but the sound quality is obviously lacking for today's standards. When mono recordings are...

I have been a bit absent from this forum (never really felt a valued member to be honest...) and concentrating on learning music theory and making music, but I decided to make this new thread. I haven't seen this aspect of human hearing talked alongside crossfeed so I bring it here: Cerebral...
