My name: Marittya Keu
For FP3, I choose to use the RSound library. Being a hip-hop head, it's only natural I choose to use a library that deals with the creation and manipulation of sounds. This is an appropriate library to use because my partner and I chose to do a project to create a game similar to Guitar Hero. For this portion of the project, I downloaded a few free .WAV files from the following websites.....
http://www.brainybetty.com/soundsforpowerpoint2.htm
http://hiphopmakers.com/free-808-drum-kit-227-samples
I took these .wav files and created them into an RSound and was then able to drive them around.....
(define sound1 (rs-read "/home/mike/Desktop/FP/ShakeYourBootay.wav"))
(define sound2 (rs-read "/home/mike/Desktop/FP/UpbeatFunk.wav"))
;creates and RSound which plays three different sound at the same time
(define sound3 (rs-overlay* (list sound1 sound2 (rs-read "/home/mike/Desktop/FP/808/clap (10).wav"))))
The code below created a function where you are allowed to play several different sounds depending on what you type as a parameter.
(define (play-sound sound)
(if(null? sound)
"Error: Must play a valid RSound"
(cond
((eq? sound 'sound1) (play sound1))
((eq? sound 'sound2) (play sound2))
((eq? sound 'sound3) (play sound3)))))
RSound allows you to do many different neat things. One of the feature is to allow you to record a sound using the record-sound function. It takes as a parameter the length of a frame of an RSound and plays it back that length
;plays sound1, records it, then plays the sound again
(define (sound4)
(play sound1)
(play (record-sound (rs-frames sound1))))
The RSound library has many useful functionalies. With it, my partner and I plan to use and manipulate the functions to create a game similar to Guitar Hero.
