Which one sounds best
How to find out which one gives the best sound – without advanced technical analysis. It is possible, and it is not very difficult.
Acoustic absorber building description
Several acoustic absorbers with different shape and size were made for the new Room 2 listening room.
Testing Amplifier Sound Quality
This is something I have though about a long time now – finding a method to reliably verify sound quality differences in power amplifiers.
Finally I have set up the necessary instrumentation to try out the method in practical experiments.

Pink Noise Calibration
Measuring more than one speaker and getting predictable and usable results can be challenging.
Using pink noise and a real-time analyzer makes it easy to check level and frequency response, and you can move the mic around to measure at different locations and still get meaningful observations.
Audibility of peak limiting
Peak limiting and clipping is used to make music seem louder, but does it really work that way?
No – removing the peaks actually reduces impact and brutality and makes it sound flat and boring.
Audibility of phase distortion
Phase distortion at low frequencies causes audible degradation of music.
When is it audible, what causes it and how does it affect sound quality.
