Setting the squelch level to 2 or 3 per cent of the maximum sample value worked reasonably well in my tests.

You may want to check for average volume over some period, rather than just all-0.<br>

This is clearly just a starting point and not a practical/useful/finished product!

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 {

// Remove the temporary files.

C.removeFile(tmp1)

<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;
