A friend of mine is looking for a good front end for his speech sampling
A/D converter.  What is needed is an amplifier for microphone input
with a good LP-filter built in with fixed/variable cutoff frequency in
the 5 kHz area.  The output can be in the 100mV to 10V range. Isn't
anyone out there that can recommend such a box?
