Description

Remarks: This is an Audio Unit, but you have to open the distribution app ones at least to install the included IR file library.

Convolution is a highly complex signal processing approach, that needs some certain computation power. The recorded impulse response of a real world environment is used to render a reverberation effect onto any audio material, so that it sounds like the source was played in that original room or at that location. Some further adjustments and manipulations can be applied to refine these results.

Now this all may sound somewhat naive at first listen but the entire calculation is extremely complex math, so that the very first processors and computers were able to perform this in realtime rather around the end of the last millennium.

Basically, the impulse responses and the audio stream are completely analyzed with FFT algorithms and then the entire analysis data will be cross-modulated into the realtime audio stream by performing a repeated highly performance intensive re-synthesis and accumulation processing for each analysis block of the impulse response.

Therefore it is a crucial performance factor that you use JAX Convolutor with larger processing buffer sizes (1024) samples. Shorter buffers may raise the CPU hit exorbitantly for several reasons.

What's New in Version 1.96

The product (AudioUnit AUv3) was updated for support of latest Apple technologies and frameworks (architecture: arm64).
Minimal iOS target is still 12.0. It also should work on the Vision Pro (compatibility mode).
