Playback Speed ChangeDescriptionThis command changes the playback speed. If a value less than 100 is given, the file will playfaster (and thus the pitch will be higher), and a value greater than 100 will play the fileslower (with a lower pitch). If the speed parameter is not received, then the playback willreturn to normal (100%).The playback speed will only return to 100% playback speed if the rMP3 is reset/poweredup,or if this command is sent without the speed value.NOTE: This command tricks the VS10xx decoder into changing the playback speed, and assuch, this is not necessarily a good/efficient way to change playback speed. The audio willmore than likely create pops and glitches. Use at your own discretion.FormatPC X [speed]Parameters• speed is an optional parameter between 90 and 250. Values outside these limits will produceunpredictable results.o This value represents the fractional speed increment for playback (percentage).o e.g. a value 90 will play the file in 90% of the time it takes to play normally (i.e.faster), whereas a value of 120 will play the file in 120% of the time it takes to playnormally (i.e. slower).o A value of 0 (zero) or omitting this value will return playback speed to normal(100%).Response FormatNULLExamplePC X 95«cr»Bart Huyskens Manual Elektor Proton V1.0 3 April 2011 112
