About this site

The mission of this website is to promote scientific values and explore some of the most controversial questions in audio. Audio is not 'rocket science' and many concepts can be understood without a degree in engineering or science. It seems complex because it covers a wide range of skills and knowledge: human hearing, audio electronics (analog and digital), audio fidelity and its measurement, loudspeakers and room acoustics.

One of the greatest misconceptions among audiophiles is that an audio system has to be extremely expensive. Hi-fi used to be an expensive hobby a few decades ago, but nowadays we can build a system that reaches the quality of professional studio equipments from the 80s for almost 'pennies' (or even better, as digital audio solved many problems of recording and playback). Computers and DAWs (digital audio workstations) gradually replaced expensive and large mixers and reel-to-reel tape recorders in the 1990s. Since the mid-1990s any computer can be used for editing and producing audio files, provided it is quiet enough. The same applies to acoustical measurements. Expensive lab equipment that only huge speaker manufacturers could afford in the 1980s has been available as free PC software for anyone since the mid 2000s (REW, HOLMImpulse). If we don't spend money on totally unnecessary components than 'hi-fi' isn't an expensive hobby.

Another misconception is that the judgment of sound quality is subjective. There is a subjective component in the judgment of sound, indeed (this is called personal preference), however the subjective component can be separated from audio fidelity. Both the objective audio fidelity and the subjective personal preference can be measured with the so-called audio parameters. And with acoustic music (music with real instruments) the sound reproduction is not subjective, it should be realistic.
