I know I've asked that before but I'm gonna ask again since I think it's one of the least hard things to implement and it's going to give pretty nice results.

Alot of games (if not most) have alot of low quality audio samples (most of them ADPCM, or AT3/PCM audio samples that have a really low sample rate) that suffer from alot of aliasing due to the fact PSP doesn't do any kind of interpolation when it resamples audio (maybe nearest-neighbor), making some of the sounds way too sharp to the point giving you a headache (sword fx and hits in general) or voice samples/dialogs sound so aliased that could easily be passed as a PS1/GBA generation sound sample.

I think (toggleable) simple linear interpolation would give a super fast and nice solution for this issue.

PS: I personally prefer Linear interpolation on audio than Cubic/Hermite/Catmull since these tend to generate some artifacts/alIasing in an attempt to fool/cover the areas that some frequencies would be missing, which is something that's I'm not really fond of acousticaly. You can try to hear what I mean using Desmume's interpolation methods.
