FamiTracker
The fact that there is a hiss IS the fix. This is what the chip actually does.
If you want to avoid the hiss you must avoid 7 and 8 channels. If you wanna use more than 6 channels, you gotta understand that the chip will produce a hiss
There are a number of workarounds, but ultimately it's best to accept that Famitracker is just one emulator. You can always write an 8 channel piece and play it in a NSF player or on the hardware itself (which sounds better than Famitracker imo).
That said, I've had some success making N163 more pleasant (without affecting other channels) by setting the low-pass filter to 20 hz / 0 dB.
Look at [url=http://famitracker.com/forum/posts.php?id=3633]that thread and listen to a few recordings of N163 NSFs that use six or more channels. Those NSFs were recorded by me on a real N163 cartridge, and you will notice that the ~15 kHz signal is quite clearly present. Famitracker emulation is correct; most other emulators are wrong.

What's the motivation for not making the N163 hiss and aliasing sound like it would through a TV? That is how the game music of 8 channel Namco games sounded like to people playing the game, after all. Unless I'm mistaken, the lowpass filter that is part of the RF demodulator of a TV makes this awful high-pitched screech much less offensive.
The only way to get this hiss audible on the hardware is by modifying a cartridge/Famicom or using strange exotic 21st century devices such as the TNS-HFC3. Either of these options just seem very inauthentic to me compared to what you'd get from a TV.
What happens is that when the sound goes through the demodulator, it goes through a lowpass filter that removes sub-15 kHz frequencies. But since no filter is perfect, some of that signal still goes through. You can adjust the treble filtering in the sound options of the tracker to get a similar sound to what you would get listening to N163 music through 1980's TV speakers. Yes, that does filter other useful frequencies out as well, but so does the demodulator in your CRT TV. ;)
You don't need to modify a cartridge or a Famicom to hear the multiplexer hiss, nor do you have to use a "strange exotic 21st century device" (I resent you calling it strange, by the way!); if you use a 60-72 pin converter to play King of Kings on an NES, for instance, you will hear it just fine!
I understand why you would want to turn the multiplexer hiss off while composing - I do it myself - but it's important to realise that the awfulness of the N163 is a reality that you have to cope with if you choose to use it.

[quote=Ryukenden]Why at playing of NSF by a player hiss isn't audible?[/quote]
Because it's not accurate. NSFPlay and FamiTracker are more accurate, and you can hear the hiss in these correctly, even if it's more annoying because of the lack of filtering.
