What specific parameter in a sampler is most critical for maintaining the original sonic characteristics of a sample when transposing it across a wide pitch range?

The specific parameter in a sampler that is most critical for maintaining the original sonic characteristics of a sample when transposing it across a wide pitch range is the sample's playback algorithm, specifically the choice of sample rate conversion or time-stretching/pitch-shifting algorithm. When a sample is transposed, its playback speed is altered. If a simple resampling method is used (changing the playback speed without adjusting the sample length), the sa....
