multiple qprocess arguments

[czilla]

I am invoking a linux system process using QProcess. The process works, but when I supply more arguments than the three prescribed arguments it gives an error.

sox.start("sox", infile.wav -c 1 outfile.wav remix 0 1);

How can I make it accept my last argument "remix 0 1"?

#include <QtGui>
#include <QApplication>
 
int main(int argc, char* argv[])
{
   QApplication app(argc, argv);
 
   QProcess sox;            //instantiate the process****
   QStringList args1;       //declare arguments
   args1 << "infile.wav";   //collect arguments to be envoked with qprocess
   args1 << "-c 1";         //collect arguments to be envoked with qprocess
   args1 << "outfile.wav";  //collect arguments to be envoked with qprocess
   //args1 << "remix 0 1";  //collect arguments to be envoked with qprocess
 
   sox.start("sox", args1); //pass qprocess and arguments to start method
   QByteArray output;       //understood by QString
   while(sox.waitForReadyRead())
      output += sox.readAll();
qDebug() << "sox" << args1;
}

#include <QtGui>
#include <QApplication>

int main(int argc, char* argv[])
{
   QApplication app(argc, argv);

   QProcess sox;            //instantiate the process****
   QStringList args1;       //declare arguments
   args1 << "infile.wav";   //collect arguments to be envoked with qprocess
   args1 << "-c 1";         //collect arguments to be envoked with qprocess
   args1 << "outfile.wav";  //collect arguments to be envoked with qprocess
   //args1 << "remix 0 1";  //collect arguments to be envoked with qprocess

   sox.start("sox", args1); //pass qprocess and arguments to start method
   QByteArray output;       //understood by QString
   while(sox.waitForReadyRead())
      output += sox.readAll();
qDebug() << "sox" << args1;
}
