Interpolation

[Guan]

Hi since i started to use XMPlay i have offen wondered what interpolation does for exampel sinc interpolation, does it improve audio quality or what does it do?

From the XMPLAY.TXT file...

Interpolation switch - MOD formats only
    "Linear" interpolation "draws" a straight line between the samples,
    "Sinc" interpolation "draws" a smooth curve between the samples and
    requires more CPU power.

So, basically, interpolation joins the dots

Yes, it improves quality, though some old MODs may sound better without it (as that's how they were created).
