GPU Impulse Reverb is an impulse reverb plug-in that does the full reverb computation on a NVIDIA graphics adapter and has a CPU consumption of nearly 0%. The plug-in requires a CUDA capable NVIDIA GPU (G80 => GeForce 8xxx or higher) and recent drivers.

The plugin loads impulse responses from stereo WAV Files between 8 and 32 bit. It can be inserted as an FX plug-in in all VST2 compatible hosts.

New in v1.09

• Supports 64-bit wav impulse responses.
• Bugfix for some 32-bit wav impulse responses loading incorrectly.
• Bugfix for some wav files causing the plug-in to crash.
• Bugfix for "Error 29" issues.

New in v1.07

• IMP: Added support for the FLAC audio format to load IRs.
• IMP: GPU usage meter now has a tooltip with more details, it reports PCIe bandwidth usage as well as computation performance.
• FIX: Fixed a possible hang if the blocksize was changed.
• FIX: Waveform display could show incorrect values.
• FIX: “High Latency” parameter was not restored correctly in a production environment.

New in v1.06

• IMP: Mono Impulse Responses are now supported.
• FIX: Plugin could crash at startup due to a VSTGUI related bug.
• FIX: Fixed opening GUI caused a reload of the current impulse response.
• FIX: Compatibility Check Tool didn't work on some systems.
• FIX: Slider wasn't always redrawn correctly.
• FIX: 64-bit version didn't work on ATI systems with more than 2 GB of RAM.

New in v1.05

• IMP: Equalizer is now applied to the Wet Signal only
• FIX: Fixed CPU spikes when using an ASIO blocksize that is not a power-of-two
• IMP: The plugin refuses to work if an NVidia card is used and the driver is too old to prevent unexcepted crashes
• IMP: The Compatibility Check displays more information and checks the driver version

New in v0.28

• Support for multiple graphics boards added. The device can now be selected by using a drop down box. The setting is stored within the projects data of the host application, so the selected device is restored if the project is reopened later.
