Channel Routing Matrix

Ircam Verb provides 16 input and output channels presenting the option for reverberation processing in multi-channel and surround formats, including Ambisonics and Dolby Atmos^®.

With a built in Input/Output (I/O) routing matrix instant flexibility is provided for configuring the I/O in relation to the physical audio monitoring in the control room.

Room, Early, Cluster and Reverb Filters

A set of 3-band filters applied to each part of the time structure for fine tuning the reverberation characteristics

Binaural technology

Binaural technology encompasses methods for recording, processing, synthesizing and reproducing sound that are specifically designed to preserve tridimensional localization properties.

In order to mimic the impression of a sound originating from a given incidence, it is sufficient to filter a mono signal, which on its own lacks any kind of spatial information, with both left and right HRTF filters. This constitutes the foundation of binaural synthesis.

Please note that the resulting signal is only meant to be listened to with headphones, and isn’t designed for a conventional stereo loudspeaker setup.

Decay Time

The Decay Time, is the duration of the reverberation tail in seconds, the time it takes for the reverberated sound to die out. In technical terms this is often referred to as the RT60 factor, the time at which the response of the reverberation to an input signal goes below -60dB of attenuation.

Pre Delay

The Pre Delay controls the time at which the reverberation portion of the effect starts to be noticed, with respect to the DIRECT signal. Increasing this helps to distinguish between direct and effected sound and preserve intelligibility, especially with large decay times and room sizes which would otherwise drench the audio material in reverberation.

Filter Section

The Filter Section controls the characteristics of the filter applied to the signal fed to the reverberation engine, affecting the overall frequency response, if required.

• Low Freq – Low pass filter frequency cutoff of the corresponding filter section.
• High Freq – High pass filter frequency cutoff of the corresponding filter section

Multiband Crossovers

Alchemists five bands are divided using carefully tuned state-of-the-art IIR (Infinite Impulse Response) crossovers with selectable slopes (from 18 dB per octave to 54 dB per octave) and variable corner frequencies.

Full control over the processing

In addition to the common controls on a dynamics processor; ratio, attack, release, Alchemist offers control over the fundamental characteristics of the dynamics processing on each band, all in order to provide full control over the processing even in the most demanding situations.

Envelope, Time and Detection Settings

• Extended envelope settings with full control of Attack, Hold and Release with Manual, Auto and Advanced release modes.
• Zero attack time for the dynamics processing by introducing a delay reflecting the attack time into the signal path.
• Eight different detection modes interacting with the time and envelope settings as well as with the integration times for the RMS detection. Includes specific “Feed Backward” modes inspired by vintage hardware architectures for producing a naturally “beefy” sound.
• Dynamic Factor – Amplifies or diminishes the extracted real-time dynamics information.
• Dynamic Velocity – Controls the speed of variation on the extracted dynamics information.

Dual Preset Slots and Parameter Morphing

The built in preset manager and the preset morphing slider, provides instant and intuitive control of all parameters and controls. In a second, with a simple one-click operation, everything is copied from one of the two preset slots to the other, even during playback.

The two Preset/Parameter slots, A and B, can be loaded with two full set of parameters at the same time, and except for only A/B comparing two sets of parameters, the morphing slider will allow to mix them, and to record the morph with the host automation.
