Tutorial 14Sampling:Playback with loopsThe info~ object can report the loop points of an AIFF file contained in a buffer~, and youcan send those loop start and end times directly into groove~.SummaryUsing info~ to get loop point information from an AIFF fileThe groove~ object is the most versatile way to play sound from a buffer~. You can specifythe buffer~ to read, the starting point, the playback speed (either forward or backward),and starting and ending points for a repeating loop within the sample. If the buffer~contains an AIFF file that has its own pre-established loop points, you can use the info~object to get those loop times and send them to groove~. The playback speed of groove~ isdetermined by the value of the signal coming in its left inlet. You can set the currentbuffer position of groove~ by sending a float time value in the left inlet.See Alsobuffer~groove~sig~Store audio samplesVariable-rate looping sample playbackConstant signal of a number132
