PONG is one of the ealiest computer games where sound was added deliberately to the game, . The sounds can be heard
in this video clip from a game of PONG, :
PONG or more accurately Atari PONG, was created by Alan Alcon. He did it as a training exercise assigned to him by Atari founder Nolam Bushnell, . In an interview, , Allan Alcorn describes how sound was added to the game:
"So I just tried to make the game better and better, and at the end of the thing he (Nolam Bushnell) said 'you've got to have sound.' Oh okay, well I'm over budget and three months into this thing and Nolan said 'I want the roar of a crowd of thousands.' Cheers, applause. How do you do that with digital circuits? Ones and zeroes? I had no idea, so I went in there that afternoon and in less than an hour poked around and found different tones that already existed in the sync generator, and gated them out and it took half a chip to do that. And I said 'there's the sound - if you don't like it you do it!' That's the way it was left, so I love it when people talk about how wonderful and well thought out the sounds are."There are three sounds in PONG:
Ball hit wall.The waveform of all three sounds is the square wave, apparently the waveform generated by the sync generator. E.g. the paddle sound looks as follows:
The duration and frequency of the three sounds are as follows:
Maybe Allan Alcorn was just lucky that afternoon when he "found different tones that already existed in the sync generator" or he had a pretty good intuition for sounds.
