In addition, memory effects when recording tapes are responsible for a part of the
characteristic sound, since time-dependent factors play a role in the feeding of the tape
reel along the heads, e.g. mutual inductance and self-erasure.
Regarding the simulation of these processes, we have concentrated on some aspects of
the "real world" and have created a virtual "machine" in AM-Track, which permits the
following interventions by using the controllers on the interface:
Level: Sets the input level. This determines when the "tape" is saturated and how strong
the effect of the coloring/soiling is. You simultaneously gain more loudness.
EQ low/hi: Adjusts the frequency response (spectral balance controller). You can
choose whether you would like to have an output signal of high bass level or whether it
should have more highs. This alters the pre-emphasis at the "recording end" as well as
playback equalization. In "Expert" mode, you can vary the employed frequencies for lows
and highs for distortion and equalization. However, note that the frequency response for
the simulation will not be neutral, even if the "EQ Low/Hi" controller is neutral. There will
always be some slight frequency-selective amplification.
Bias: Moving the operation point (bias adjust). Increasing the bias will result in a higher
"recording level", but tape saturation will occur sooner. You will also increase the above
mentioned loss effects, and the result will be a (dynamic) reduction of the highs. Turning
the bias controller to the left results in the opposite effect: the highs are not reduced, but
the signal level stays lower.
Tape mix (in the "expert" section): Anything that applies to a parallel compression can
also be applied to the tape section. Non-edited transients in particular are responsible
for perceiving "speed", "liveliness" and "freedom", but may be lost in case of too much
saturation/overdrive. Mixing in the original slightly enables you regulate the band quite far
while still retaining the so-called attributes.
