Audio Comparison PCM with Linear Interpolation
Added 2019-04-11 11:08:25 +0000 UTCFollowing on the previous topic about linear interpolation. I have improved it on the Megadrive sound chip core JT12. This core already made a x2 interpolation by default. Now I have extended it to arbitrary numbers.
This increases the sound quality of the Megadrive but for games with very poor samples the difference in sound is very large so I guess that somepeople may prefer the aliasing sound just because it was what they grew up with.
I have made the comparison with Megadrive rather than with NeoGeo as Megadrive games often have poorer quality on PCM so the difference is more obvious.
There are three samples played twice, first without interpolation and second with interpolation. What do you think?

I would try comparison by using my "Mega Blaster" as it has a real YM2612 chip and a PCM Playback capability via the real chip.
