The audio sampler allows you to sample a realtime audio waveform or frequency spectrum. You can specify which audio channel group you wish to sample. It is useful to make the particles react to audio, and supports easy-to-use convolution to sample the spectrum a different levels-of-detail.
Audio samplers can be sampled with cursors in the [0;1] range to extract frequencies or waveforms.
Audio samplers are most commonly used with the following templates:
