Frequency and time are conjugate variables. Pick one.

And neuro-acoustics. But as you said, nobody in audio seems interested to know how we really hear....

Jan, I'd disagree a bit. No one in fashion audio, perhaps, but among real audio engineers, there's a keen interest in perception.

I perceive what I perceive. At least that. While I cannot hear as extendedly or as acutely as I could 30-40 years ago, I am self trained to still hear differences in audio products that may, in fact, be subtle, and little use to many others. I started off in life better at this than most, and instead of becoming a superior musician, I became a superior listener of musical instruments and musical playback systems. That is one useful attribute to someone who designs audio equipment. As the 'specs' do not reveal everything, and even advanced measurements often run into dead ends, it is necessary to know when you have really made a successful design, and when you have only made a mediocre one, that will last only a short time, and be forgotten.

Almost every time that I left out the IMPORTANT ingredient of ATTENTION TO DETAILS, coupled with not seriously listening to the audio product under development, I have failed (big time to me) in the marketplace.

I have actually gotten too confident, a number of times, and fell flat with both customer and audio reviewer acceptance, with NOTHING ELSE changed in the equation. Not the appearance of the product, not the advertising of the product, and not the promotion of me associated with the product. I learn from my mistakes, and I am here to advise others to avoid my mistakes that I have made in the past.

I agree Stuart

BTW: Happy "distortion-free" New Year to everyone.

Cheers
