Re: [LAD] Hi, I'm new

[Guy Sherman] The principle is indeed the same, and you could use a converter library for this purpose. However, those converters are designed to work over a continuous range of samplerate ratios whereas the ratio chosen for oversampling is usually a fixed integer because this presents ample opportunity for optimisation. The interpolation filters in both cases are usually windowed sinc FIR (much like the Lanczos kernel in image resampling). As you intuit: you sample up, process, then sample back down, ending up with one output sample for every input sample. IIrc, http://quitte.de/dsp/caps.html contains at least two oversampled plugins and comes with source code. Cheers, Tim
