Igor Vasiliev’s AltiSpace 2 extends beyond standard convolution by allowing real-time manipulation of the loaded impulse response. Users can stretch the IR in time without affecting pitch, shift its pitch without affecting duration, or apply envelope shaping that changes the IR’s amplitude over its playback. This transforms a single IR capture into a family of related spaces, from subtle variations to extreme transformations. The built-in library includes over 200 IRs from diverse sources.
The plugin runs universally on iPhone, iPad, and MacOS with AUv3 and standalone support, maintaining consistent IR manipulation across platforms. Within hosts like AUM or Cubasis, users can automate IR parameters for evolving spatial effects. The gate and modulation sections add further dynamic control over the convolved signal.
User feedback on the Igor Vasiliev user group notes that the IR manipulation features, while powerful, require understanding of convolution principles to use effectively. Some users also report that extreme time stretching can introduce audible artifacts, limiting the usable range for transparent applications.
Key features include:
- Convolution reverb with real-time IR manipulation
- Time stretching and pitch shifting of impulse responses
- Envelope shaping for dynamic IR control
- 200+ factory IRs covering diverse spaces
- Gate, modulation, and EQ for additional processing
- Low-latency
