A simple example;

#include <stdio.h>
#include "bass/bass.h"
#include "bass_sox/bass_sox.h"

int main()

	int output_rate = 192000;
	DWORD source_channel;

	if (source_channel == 0) {
		return 1;
	}

	playback_channel = BASS_SOX_StreamCreate(output_rate, BASS_SAMPLE_FLOAT, source_channel, NULL);
	if (playback_channel == 0) {

	}

	//These settings are optional.
	//Defaults to medium quality, 1 second buffer and 1 thread.

	if (!BASS_SOX_StreamBuffer(playback_channel)) {
