Introduction

Sound Forge Pro is a one-of-a-kind, powerful algorithmic reverb effect. It creates the sound of a wide range of acoustic spaces, from small rooms to large concert halls, and works equally well in stereo and 3D multi-channel files with up to 10 audio channels.

NOTE 3D Reverb is only available in Sound Forge Pro Suite!

Input signals are routed into the virtual room according to their 3D panning, which supports the spatial impression of Surround sound mixes.

The calculation of early reflections is based on a geometric spatial model that is automatically adjusted to the audio channel configuration to obtain a reflection pattern that exactly matches the positioning of the incoming audio signals. This allows the existing 3D panning in a project to be used directly to create reverberation that matches the placement of the source signal to produce an impressive 3D sound. Late reflections are based on a feedback delay network with 16 delay lines (FDN16).

Decay times range from <100 ms to infinity and are independently adjustable for high and low frequencies. There is an attenuation filter for further processing of the room signal frequency spectrum. The early reflections can be diffused, the late reflections can be made more lively using modulation. On the output side, there is an equalizer and a Spatial Balance control for adjusting the spatial placement of the reverb signal.
