Frequency Processor

The equalizer included in Turbo Play is a featured Graphic+Parametric EQ tool.

Features:

• 10,20 or 31 bands for Graphic
• Low/high cut and low/high shelft based on Chebyshev I/II, Butterworth or elliptic filter with configurable order, ripple and roll off
• Peaking filters with Q

Based on the nice DSPFilters and SNDFilter and IIR1 and my own work, Turbo Play provides you a full set of scientific filters:

• Butterworth
• Chebyshev I
• Chebyshev II
• Elliptic
• Bessel
• Legendre
• Biquad
• Windowed-SINC

All filters are configurable in lowpass/highpass/bandpass/bandstop and there are configurations for Q, ripple, rolloff, and order for the filters that support these parameters.
