Hi,

A friend of mine has given me a recording of an interview he did with
Chet Atkins some years ago on cassette tape.

It's a very bad quality recording - there is an aircon/fan hum & the
voices are unintelligable:

That's the quality of the original recording - I've tried chucking it
into cool edit pro & done a noise reduction thang by sampling the fan
noise & removing that but not had much joy..

- any tools/techniques that could at least get the voices intelligable
enough to be transcribed?

I improved the intelligibility quite a bit with CE's FFT equalizer. Flat
from 300 to 800 Hz, sloping to 30 dB down at 100 Hz, sloping to 40 dB up at
2 KHz, and then sloping down to -30 at 20 KHz. Then, the clipping during
transcription was more of an irritation than the booming and fan noise.
