How to use the amodem.main.send function in amodem

def sendAudio():
         with AUDIO_INTERFACE:
            src = StringIO.StringIO(self.debugWindow.toPlainText())
            dst = AUDIO_INTERFACE.player()
            mainAudio.send(CONFIG, src=src, dst=dst)

        main=lambda config, args: main.send(
            config, src=wrap(Compressor, args.src, args.zlib), dst=args.dst,
            gain=args.gain, extra_silence=args.silence
        ),

                dst = interface.player()
                amodem.main.send(config=self.modem_config, src=src, dst=dst)
