d16 are very pleased to annouce that Toraverb has been officially released. Toraverb is not a classic type reverb unit like spring, room, hall or plate. Toraverb is a “concept” algorithm reverb. Using a set of easily accessible parameters, it promises to allow the creation of any type of reverb.

Reverb can be a critical effect in a mix. Final results depend on the reverb algorithm used and the quality of the implementation. Usually reverb is used as a send effect in which many channels in a mix are routed to it. If a low quality plug-in or hardware unit is used, the end results can sound very disappointing with the reverb tail sounding like it had been “ripped-off” in the mix.

In Toraverb, d16 applied high quality diffusing algorithms based on modified all-pass filters. By doing this and using properly tuned parameters, they claim to have almost entirely eliminated unwanted flutter echo effects for every sound source. Toraverb is equipped with two independent, single band, fully parametric equalisers. One is used to EQ early reflections and the other to EQ late reflections. This allows a lot of control over the character of the reverb to achieve a more natural sound.


Toraverb also has an additional modulation parameter which affects the diffusing filters. These are responsible for the distribution of the sound waves reflections in time. By changing the modulation, the sound of the reverb tail can be altered to give a more realistic effect of sound propagation. To give a better impression of physical space, d16 added an innovative algorithm to Toraverb which improves spatial reflections by allowing cross-talking of reflected stereo waves between stereo channels. This models what happens in the real world when a sound audible only in the left ear is reflected and is heard in both ears.

On the Mac, Toraverb requires OS X 10.4.3 or later, a 2.0 Ghz processor (Intel Based 2.4 Ghz or faster recommeded), 512 MB of RAM (1 GB recommended), and an AU or VST host.
