WebFeb 13, 2024 · Yes. The "right" way to do it when downsampling is to first apply an anti-aliasing filter and then decimate the signal but when upsampling, you first upsample and then apply interpolation (which can also be expressed as a filter). Various platforms provide functions to do just that (e.g. Python, MATLAB ).

WebIf you think about it, this is exactly the same process as when you send audio out through your interface’s D-A converter and back through its A-D converter. The D-A converter reconstructs the analogue waveform, and the A-D re-digitises it, via the appropriate anti-aliasing filter, at the new sample rate.
