Breakout sound effects

[trillykins]

Hi

 

Had to make a Breakout clone for an assignment at school, so I thought it'd be fun to remake the Atari 2600 version of the game. The entire thing is done, but it's oh-so silent at the moment. No sound effects.

 

Anyone know if there's a site somewhere that has all the original sounds? Also, anyone know how sounds were handled in the game; random sound effects, looped list of available sounds, maybe some specific algorithm based on which colour brick you hit etc..?

 

Thanks in advance.

Nothing that complicated. Breakout only uses a single channel. Distortion register AUDC0 is given value $0C for all sounds (div 6: pure tone). Volume register AUDV0 is set to highest for all sounds ($0F). Data table LF792 holds the tone frequency (AUDF0) for the brick hit...$1C,$16,$12,$10,$0C,$0A (lowest to highest) - unless the upper/side wall or paddle is hit ($02,$04,$08). A single delay timer holds the number of frames to hold the note...looks to be 6 for hitting bricks. Or are you referring to Super Breakout...which uses multi-frequency notes on both channels?

I find Super Breakout to have more interesting sounds.

 

Possibly you could just write a short program that simulates the LFSR that gives each AUDC type it's waveform, use it to generate wave files of the sounds you want to use.

Thanks for the help. Figured something out.

I am also making a breakout clone for school and was hoping you remembered how you figured out the sound and could help me out?
