Audio Recording and Automatic Gain Control
By Alan Turner

The comments about the Automatic Gain Controls on cheap (and even
expensive) modern audio recording equipment reminded me about the same
issues I had a few years back, when I first tried recording the
performances of my newly restored Duo-Art grand piano.

I got around the problem by buying an older stereo cassette deck (the
one I bought was a Techniques mid-grade from the early '80's).  What I
looked for were the direct microphone inputs on the deck and a
headphone monitoring channel on the deck.  I was able to pick this
machine up at a local auction for under $10.00.  They are out there
cheaply available.

When I recorded, I didn't use any of the noise reduction built into the
deck and I adjusted the gain to just miss any distortion on the loudest
passages in the music.  Once I got the raw recording on cassette, I
hooked the deck up to my computer and transferred the recordings onto
the computer, initially as WAV files, later converted to a format I
could burn onto CD.

My dilemma has been to add this quality recording to a video image,
properly synced to the image.  I didn't spend a lot of time on this,
because I was primarily interested in making the audio recordings so
that I could listen to them on CD.
