Summary
- Plugin name : Signal Resampling
- Version : 2.0
- Author : Quentin Barthelemy
- Company : Mensia Technologies SA
- Short description : Resamples and re-epochs input signal to chosen sampling frequency
- Documentation template generation date : Oct 29 2020
Description
The input signal is resampled, down-sampled or up-sampled, at a chosen sampling frequency and then re-epoched.
This plugin can apply a downsampling or an upsampling, to/from any sampling frequency, including non-integer sampling rate conversion. The signal is low-pass filtered with a FIR filter to avoid spectral aliasing, using a sinc function-based fractional delay filter bank.
If the sampling rate is badly conditioned, this plugin can induce latency.
Inputs
1. Input signal
An input multichannel signal , composed of channels and temporal samples, at the sampling frequency .

Outputs
1. Output signal
An output multichannel signal , composed of channels and temporal samples, at the sampling frequency .
- Type identifier : Signal (0x5ba36127, 0x195feae1)
Settings
1. New Sampling Frequency
New sampling frequency . No processing is applied if .
