Think of a sampled waveform as a stream of these spikes. We call the spike’s reverb tail the impulse response of the church, and we make a recording of it. Playback of this spike in a church would create a reverb tail, a response very similar to that of a hand clap. That’s just one loud sample, surrounded by silence. The shortest impulse in digital audio is a single sample ‘spike’. Take a look at the illustration on the left. What is Altiverb and how does it work ?Īltiverb makes your audio sound as if it was played back somewhere else, adding the acoustics of existing spaces to your own recordings or to your live audio. Together they are the state of the art of reverb based on real spaces.Ģ. Audio Ease is glad to welcome you to Altiverb version 7, and to the Altiverb Impulse Response Library. So let’s sample one click and its response from a room:Īnd apply the response to the first click in the sampled waveform:Ĭopy the same response again (a bit louder) after the waveform’s second click:Īnd proceed to do so for each sample in the sampled stream:Įach sample gets its own scaled reverb tail, and the waveform now sounds as if it was played back in the room.Īltiverb has come a long way since it premiered as the first real-time convolution reverb plug-in in 2001. the Browser page 18 - Selecting and saving presets, Similar page 19 - Pictures, About, Preferences page 20 - Gated verb, Positioner page 21 - Snapshots, Ir Import page 23 - Waveform, IR info page 24 - Waterfall Diagram page 25 - EQ-curve, Reverb time page 26 - Bright, Size, I/O tab page 27 - EQ tab page 28 - Damping tab, Time tabĪ sampled waveform is nothing but a bunch of clicks: Consult the owner of the venue when you intend to do so.Ĭontents 1.
