Whenever I buy a CD, I put my favorite songs in my PC. I use Wavelab or
Adobe Audition to convert the stereo file to mono. But its more
complicated than just stereo-to-mono conversion. First, I make two
copies the stereo file. With one copy, I invert the phase of the left
channel and then combine it with the right channel -- this causes
whatever was identical the left and right channel to be cancelled.
Before I combine these two channels, I decrease the loudness of each
channel by 50%.

With the other copy of the stereo file, I don't invert either the left
or right channel. I simply decrease the loudness of both channels by
77.5% and then I combine the left and right together to make a mono
file.

I then combine the audio of both copies together in a new WAV file.
Voila! I get some nice monoaural audio with at least 44.1 khz and at
least 16-bit.


Anybody?


Interesting approach. It appears he's making a mono sum by

..5(R-L) + .775(L+R) = 1.25(R) + .25(L)

I guess he hates the leftt channel. More cello, more bass, less violin,
less percussion. Hey, whatever floats your boat.
