Q: Could you explain the otion "Use high speed mode when resampling needed"?
A: When would the converter do resampling operation? If the conversion is from one sample rate to another different sample rate, the converter would resample the audio sample, in other words, the conversion would include the resampling process.

If the conversion dosn't include the sampling process, this option doesn't affect the resulting files whether the box is checked or not.

If you uncheck this option, the resampling would work in high quality mode. This mode is slow, but it would give better audio quality results.
