Audio overlap loop: Difference between revisions

{{draft task}}

'''Audio Overlap Loop''' is a program that produces an "echo chamber" effect by playing an audio file several times in an overlapping loop. A repetition level determines the number of times that the file is looped. For the purpose of this task, write a program that takes a parameter for the number of repetitions and plays the file ''loop.wav'' in an overlapping loop according to the number of repetitions.

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.

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.

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

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

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 {

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

#include <stdio_ext.h>

#include <stdlib.h>

return 0;
