Acoustic filters (audio-filter?)

[dy]

There are various standards for acoustic filters for different applications. Among them:

• ITU-R 468 Noise weighting
• Rumble filters
• ISO-226 equal-loudness filter
• IEC-386 flutter filter

There are s-plane formulas for some of them, for others there are not.

There are also standard digital filters: Bessel, Butterworth, matched, elliptical, Linkwitz–Riley, Chebyshev, biquad, Savitzky–Golay and others.

As a concept it may be nice to join all known filter types into a single pack, akin to color-space, and name it audio-filter.

Sounds good to me!
