The Nt Mini's audio has come under some criticism from such luminaries as the My Life in Gaming channel. Kevtris has fixed NES audio issues in Jailbreak firmwares v1.0 (MMC5 pulse pitch), v1.3 (audio sweep bug), and v1.8 (crackling static issue). The excellent MLiG video was using v1.2, so its statements may not hold true for the latest official or jailbroken firmware. Even so, it is hard to diagnose and fix a problem without being able to define the problem or demonstrate it in a way that would illustrate the problem to the less-technical viewer. The MLiG video said little more than "We feel that sound might be somewhat further removed from the original hardware experience than any other aspect of the system."





That MLiG comment is so vague as to suggest that the Nt Mini could be outputting reversed-duty cycle pulse waves like a Famiclone or too low pitched noise as with the NES Classic Edition, which it clearly does not. Nonetheless, a more articulate critic of kevtris' APU implementation in the Nt Mini and Hi-Def NES Mod is that in certain musical tracks, the triangle and noise channels are too quiet compared to the two pulse channels. In order to talk about this claim, first we must discuss the mixing levels of NES APU channels.
