Simple Sounds for Linux, Page 2
Using the beep program, it's easy to play simple melodies. Here are the frequencies for some basic notes:
To find the frequencies of subsequent notes, simply multiply the highest note you know by 1.0595, and then round up or down as appropriate. For example, 494 * 1.0595 = 523.393, or 523 Hz, which should be the "C" note that's one octave above middle C. 262 C - "middle C"
277 C#
294 D
311 D#
330 E
349 F
370 F#
392 G
415 G#
440 A
466 A#
494 B
Here, then, is a script that plays a portion of Beethoven's F|r Elise:
The only problem with "beep" is that it's not very efficient. That is, you're consistently calling a program, and as such, the timing might not be absolutely perfect. As I said, Linux is often used for servers, and it's highly likely that other processes will be running at the same time. Therefore, you may experience some delays between notes. #!/bin/bash

YahooBuzzOne solution is to include beep's code within your own C program(s). This will definitely speed things up, as the program won't have to be called 400 times to play a tune.
