In the starting post, it was not specified that resampling was also used - the question was:
"Is it possible to use a filter to compensate for high frequency signal loss due to interpolation? For example linear or hermite interpolation." Without specifying that variable rate playback is involved, that could be understood in various ways - for example, at first I thought the interpolation was for the purpose of a (static or modulated) fractional delay line. A third possible situation is using linear/hermite interpolation as an upsampling filter in a 2^N oversampler. It was only specified 18 posts later, that the interpolation is used for variable pitch playback. These three situations all are different, and different formulas apply... And the combination oversampling and linear/hermite interpolation can also be meant in multiple ways. _______________________________________________ music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
