Resampling methods are not all created equal. Some are better than others. By "better" I mean correct mathematically, precise numerically, and transparent perceptually. Without getting into the details, can we establish some pragmatic rules of thumb?
Here's a first draft strawman to throw darts at:
1. Avoid resampling if possible.
2. If you must resample, use integer multiples, as they are computationally simpler and perceptually more transparent.
3. All else equal, upsampling is more transparent than downsampling.
For example: if the source is 88.2 kHz:
1. Listen at 88.2 if possible (no resampling).
2. If you must resample, better to downsample to 44.1 (integer multiple) than upsample to 96 (or worse, downsample to 48).
