Ableton/Live/UG/29 Audio Effect Reference/30 Redux/01 Downsampling
- The downsampling controls are on the left. Without filters, downsampling adds inharmonic content that depends on the material and the chosen rate.
- Rate — the sample rate the signal is reduced to; lower adds more imaging and inharmonic tones
- Jitter — noise on the downsampler's clock, adding randomness, noise and stereo width
- Pre — filter before downsampling, narrowing what gets downsampled (and the Jitter width)
- Post — low-pass after downsampling to reduce imaging. Post-Filter Octave sets it in octaves above or below half the Rate value.
