Summary	08986: dkong and clones: Run and jump sounds too low-pitched and quiet, audio is too bassy
Description	I am fully aware this issue has been reported before and closed. I am also aware that there are subtle differences in analog audio between individual PCBs, and that cabinet acoustics affect game sound. However, I do not believe the acoustics to be the issue here, and I noticed that on all cabinet and PCB footage I found plus on all-original cabinets that I have played personally, while the pitch of the analog sound does vary slightly between the examples, they all fall within a relatively consistent range, which is always much higher than it sounds in MAME. Additionally they sound louder and crisper. In addition, it's possible that the current low-pass filter being used is a bit heavy on the bass compared to the PCB recordings, maybe one closer to that which is currently used for Donkey Kong Jr. would work better. Video examples: Cabinet: PCB: Update: Here's another great PCB reference:
