How can a computer identify and select all the frequencies including all the harmonics of one instrument or singer in an ensemble then cancel those sounds from all the other channels??

You do realize that I'm multitracking, right? The computer doesn't have to do that. As some point our AI overlords might be able to figure that out though.

Blumlein pairs with two matched front and rear microphones is used for stereo with only two speakers not used with an array of speakers.

Sound is wonderful

As youngster, when I could still hear, the company I was with was experimenting with these

Working in studios, and hearing just what two speakers could do was amazing, till I went home to my stereo, even with a pair of ELS 63's, the sound was not the same, dammed room....

We used to record all concerts with stereo pair, and spot microphones, as well.

Many discussion over "coffee" etc on benefit of crossed / none crossed pair, spot add ins, sound field,

In end, I cam to conclusion that we had a fundament
My thought is
in the real world, we are presented with pressure waves,
which our two ears process to make direction,

There is nothing in that that says how the pressure waves were produced,
be it two speakers, 3, or 5 or 19

Personally
wearing DT100 headphones for hours on end
I always though the best sounding "natural" was

but thats controversial

Sound is fun,

I don't think that should be controversial. Binaural is beautiful.
The reason is that it's very natural.

 

Some of my friends asked me how to make their stereo sound better. Just like the people on TV at home with the microphone hidden far away, their listening room is an echo-chamber. My listening room has a carpet and walls and the ceiling at different angles.

Bookshelves are a great way to break up sound. Also pull your Magnepans out 3 feet into your room. LOL

 

The HIFI Berry Amp2 produces only 14W per channel into 4 ohms with distortion at 0.1% or less when its power supply is 12VDC.
They do not say the distortion over all frequencies so it might produce intermodulation artifacts at high audio frequencies.

A class-D amplifier IC uses PWM.
There are many higher power class-D amplifiers with better specs available that are already designed and made. An example is the TPA3116 by Texas Instruments.

See, that's what I'm talking about! Thank you!
