Cubic Upsampling for Streamed Music? by MoldyPond at 4:52 PM EDT on October 17, 2018
Purely for experimental purposes, but does anyone happen to know if there are any ways to "upsample" streamed songs (WAV/FLAC) like the cubic upsampling options for NES, GB, Genesis, etc.?
For DS music, cubic seems to be the one where not only does it make it sound better than it normally would, but with 0% innaccuracies that I can notice at all, having used it for about 25 games or so.
If you want something similar under XMPlay, use these output settings:
SRC slider on the lowest setting uses 4 samples, with each step in the right doubling the number. And it really does sound best for low (11-22 kHz) frequency input at 4 samples.
