Curve Comparison : Bell Middle settings
The standard digital filter does not match at all the analog reference, the orfanidis one is not matched very well and the AMLT one is matched until 20kHz
AMLT® Bell Curve Comparison

Here are some curve comparisons between standard digital filters, orfanidis filters, AMLT filters and the analog reference.

On the first screenshot, different algorithm curves for a bell boost are showed, for mid range settings.

Purple : 0dB
 Red : Standard digital filter
 Blue : Orfanidis filter
 Green : AMLT
 White : Analog reference










Bell Extreme Settings
For high frequencies and high Q-factors, the shape of the equalization curve is very important
On this second screenshot, settings are more extreme, and it is for this kind of settings that an excellent digital filter curve, i.e. very close to the analog reference curve, is very important for a good sounding equalization.

Purple : 0dB
 Red : Standard digital filter
 Blue : Orfanidis filter
 Green : AMLT
 White : Analog reference
A warped and unsymmetrical curve makes your equalization sounds metallic and unnatural.

You can see here that it is impossible to match standard or Orfanidis filters even for the lowest part of the curve : in this example, the analog reference can be matched up to 6-7 kHz, but not further.

AMLT® is matched with the analog reference up to 20kHz.
