  • 7.0.1 fixes a lot of smaller issues, it is recommended to download and install this update if you first installed Altiverb 7.0.0 from the DVD.

New in Altiverb 7.0.0 (Dec 12, 2011)

  • Look & Feel
  • Altiverb 7 looks and feels better. Often used controls all line up on the front, while the more exotic ones are in drawers beneath.
  • Picture Browser:
  • The IR library is more accessible then ever because of Altiverb's new visual browser: quicker loading, organize-by-size, and single click favorites.
  • Keyword Searching:
  • A powerful keyword search field makes you find items like 'metallic resonances' 'bed room', 'street slapback' or 'brick studio'
  • Brightness:
  • An algorithmic synthetic reverb layer that is tightly tailored to the impulse response provides a type of brightness that an EQ could never boost from a real world room.
  • News:
  • Keep your IR library up to date from within Altiverb. You can go into Altiverb's news tab, see what's new and proceed to download and install without restarting, all from within Altiverb 7.
  • Similar
  • The room does work, but it is not quite the perfect one yet? Hit Similar and Altiverb will suggest similar sounding alternatives to the chosen impulse response.
  • TDM simplified:
  • In Altiverb 7 XL, the TDM chip management can be done from within Altiverb, using one handy pop-up menu. This feature does away with the long list of Altiverbs in the TDM plug-in popup. On top of that Altiverb 7 XL allows the loading of all IR types (down to mono in / mono out) into a stereo to quad instance of Altiverb.
  • Total Recall Automation:
  • Everything, including the impulse response choice is automatable in Altiverb 7. This means that you do not have to jump through hoops to fully automate Altiverb 7. And while there are still single-click snapshots, you do not need them to automate Altiverb. You can even read which IR is chosen in the automation curve.
  • Drag and drop:
  • Just drop any audio onto Altiverb 7 to use it as an impulse response: sweep recordings, several type claps or bangs, or any kind of experimental audio like crashing cars or piano chords. The drag and drop IR feature includes new make-up curves that allows the making of decent IRs using a handheld portable radio, or even slates. Read more
  • Chaos:
  • Dial in a bit of chaotic modulation and not every hit will sound identical in the reverb. As a bonus tonal material will be dispersed which means that slightly out of tune notes will be covered up in the reverb tail.
  • Interactive EQ curve:
  • To operate the equalizers you can still use the familiar turning knobs. But Altiverb 7 adds an interactive equalizer curve that allows you to set al four bands including the widths of the parametric ones.
  • And More:
  • Altiverb supports 64 bits. It has a new reverb gate, and straightforward pre-delay and attack parameters. Times can be set in note values locked to your song's tempo, and you have 10 times as much space in the stage positioner.
