	def _calc_gain(self):
		song = Song(url = self.url, _useDb = False)
		try:
			song.openFile()
		except IOError as exc:
			return {"error": exc}
		import musicplayer
		try:
			duration, gain = musicplayer.calcReplayGain(song)
		except Exception as exc:
			return {"error": exc}
		return {"duration": duration, "gain": gain}

Example #2
