Hi! I've been working on a video that chronicles the development of video game console sound capabilities, I had a few questions regarding the Atari 2600 as the documentation on its audio hardware is much harder to come by than, say, the SNES. I thought who better to ask than people who actually make Atari games. All I know at this point it that the TIA generates "two channels of one-bit sound. Each channel provides for 32 pitch values and 16 possible bit sequences. There is a 4 bit volume control." (Wikipedia)
From this available info I have a few questions:
Because it has "32 pitch values" this means it can play 32 different "notes" correct?
If it has "two channels of one-bit sound" why do games like Pitfall 2 have music? I heard about extra chips?
Later on in the Wikipedia Article for the TIA it states that the Atari can generate "pulse and noise output" is that any similar to the pulse and noise channels the NES has? (I'm guessing so).
And lastly, why are is so much of the music found in Atari games completely out of tune?
Thanks in advance, even if you only know a moderate amount of information about the subject I would appreciate an attempted answer, the video I am making is for a general viewer who isn't particularly tech savvy so I will be simplifying it anyway. I've also been reading Racing The Beam looking for possible answers. Not a programmer in the slightest.
