'warm sound' = euphonic distortion not present on the
source tape.
Pretty easy to simulate, if you are handy with an equalizer.
How to increase "warmth":
Q = 1.2-2.5 rise of a few dB around 150-200 Hz.
Roll off those nasty thuddy dark lows below about 90 Hz.
Overall downward slope of -0.5 to -1 dB/octave from 20-20 kHz.
Q=8-12 notch of 3-9 dB around 9 kHz.
Gently roll off above highs about 6-8 KHz at -6 to -12 dB/octave.
Advanced processing that is easy enough with good DAW software, but can't be
done with just an eq:
Add just a little 60, 120, 180 Hz hum.
Overall dynamics compression to eliminate hard-to-hear quiet passages,
and ear-shattering loud passages.
Add even-order distortion to loud passages
Add red-shaped noise to low-level passages
Add just a little modulation noise
Random or cyclic changes to channel balance and phase to widen perceived
soundstage.
