=={{header|Go}}==

As Go does not have any audio support in its standard library, this invokes the SoX utility's 'play' command with the appropriate parameters to achieve the 'echo chamber' effect.

 

import (

err := cmd.Run()

check(err)

 

=={{header|JavaScript}}/{{header|HTML}}==

var j = prompt("Enter the sound manipulation level you want", "");

for(i=0; i<j; i++) {

document.write("<bgsound src='loop.wav'>")

}

 

 

=={{header|Julia}}==

Uses Julia's ability to run iterations of a 4 loop in separate threads to play a file 4 times, with each play 0.1 seconds out of sync with the previous play. Requires available threads on the CPU at Julia startup.

 

if length(ARGS) < 1

end

end

{{trans|Go}}

As in Go version, we use Sox "play" command.

 

proc getValue[T: int | float](msg: string; minval, maxval: T): T =

args.add $(i * delay)

args.add $decay2

The distributed version also has a loop/wait for all channels to finish playing

before terminating the program, or you could just use sleep() or as above wait_key().

Either of these may be desirable in different circumstances, so both are left as an example.

{{trans|Go}}

The ability to call external processes such as ''SoX'' is expected to be added to Wren-cli in the next release. In the meantime, we embed the following Wren script in a C host to complete this task.

 

class C {

args.add(decayS)

}

<br>

We now embed this in the following C program, compile and run it.

#include <stdio_ext.h>

#include <stdlib.h>

free(script);

return 0;
