Authorisation is via the Audio Ease web site using a challenge-and-response system or to an iLok key, which has the advantage of allowing you to move the program between computers more easily.Īltiverb 's plug-in window is a hint on the wide side and offers relatively few controls the reason for the amount of real estate is the colourful reverb display, which can show either the IR decay profiles or a 3D waterfall plot. Altiverb v2 was the last version to support Mac OS 9, and the current version is strictly OS X-only. The all-important IR library has also been extended and of course there's support for plug-in formats that didn't even exist back in 2002, such as Audio Units. Where reverb is required in the centre channel, they have a mode where the rear reverbs are summed to mono and then delayed before being fed to the centre speaker, though this is recommended mainly for film work rather than music. The two basic surround formats are mono-in, quad-out and stereo-in, quad-out, which Audio Ease feel produce the best subjective sound for music.

Growing UpĪltiverb has evolved since its inception, with perhaps the most significant addition being the ability to produce surround reverb effects, though the way this is achieved is rather different to the way some competing products handle it. Similarly, amplifier distortion and compression can't be emulated using conventional convolution. You could for example, use it to model the response of a favourite equaliser setting or even a guitar speaker cabinet, and it will also sample delay effects (including hardware reverb devices that don't use internal modulation), though anything that uses modulation, such as chorus, flanging and vibrato, can't be captured this way. Like most convolution devices, Altiverb can also be used to sample other linear processes, by which I mean ones that don't include time envelopes, pitch modulation or distortion.

The included Altiverb IR Pre-processor is a separate software application that allows you to use sine sweeps, balloon bursts or starting-pistol shots to sample your own spaces. Normally you work from a library of impulse responses recorded in concert halls, studios, clubs and other acoustically useful places, but it is also possible to create your own. These days, however, we can take advantage of what they have to offer without trading that off against the use of other plug-ins. All convolution-based reverbs are extremely processor-intensive, and back in 2002 when the Mac G4 was the epitome of power processing, running a convolution algorithm ate up a lot of the available processing power.

Since we first reviewed Audio Ease's Altiverb Mac-based convolution reverb plug-in back in 2002, many more convolution-based plug-ins have sprung up, but Altiverb still has a reputation for sounding a little bit special. Altiverb was one of the first convolution reverbs.
