493Hz to 21.18Hz
Sets the frequency where the transition between mid frequency and high frequency takes place. The parameter (in combination with High Multiply (HIG)) simulates the effect of air absorption in real environments and reduces the reverb time at high frequencies – the amount of reduction is controlled by High Multiply (HIG). With a relatively low setting, the reverberation will have a darker tone. A typical setting for simulating real halls is 4.6kHz.
This is a continuous parameter on the plugin, which interpolates between the discrete values found on the original. Set the value to 4.62kHz when using the Ambience algorithm for true emulation.
