Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: Thanks; trying to clarify my confusion

I've always had a slightly different definition:

Oversampling came to be used in relation to the digital filter used in a DAC chip. Upsampling was an increase in sample rate to the data sent to the DAC chip (which was then oversampled by the filter in the DAC chip)

In some instances the upsampling was done in hardware (usually with an ASRC chip) and some times it was done in software. The software upsampling could either be done realtime by a program as it played a file, or the file could be upsampled to a new larger file.
