The encoders listed to the right don't achieve that. 55 55 Any ideas where I could get sources? 56 http://www.hydrogenaudio.org/forums/index.php?showtopic=102699 57 http://www.hydrogenaudio.org/forums/index.php?showtopic=102875 58 http://www.hydrogenaudio.org/forums/index.php?showtopic=102876 56 59 }}} 57 60 … … 145 148 146 149 Please note that the bitrates listed here assumes the input audio channels is Stereo and the sample rate is >= 44.1Khz.
