Thanks Frank,
I use cubic interpolation to interpolate between samples and it seems a
bit better than linear for me. I am more worried
about the downsampling, when the playhead is going faster than the
original samplerate and that's
when the high frequencies of the original material start to
Hey, Frank —
I use four-point, third-order hermite resampling everywhere. It's fast,
relatively simple, and as good as will be necessary for most applications.
Linear resampling can introduce some perceptible harmonic distortion into
higher frequencies. This will be especially noticeable when
Hi Kevin.
I'm the least-expert guy here I'm sure, but as a fellow newbie I might have
some newbie-level ideas for you.
Just to mention something simple: linear interpolating between samples is a
huge improvement in reducing aliasing over not interpolating. For instance
if your playback math
