sfplay~ Tips and Workarounds
- Most objects in Max that play audio files usually reference data that has been loaded into RAM via a buffer~ object. sfplay~ is unique in that it streams audio directly off your hard drive.
- You may prefer to use sfplay~ for large audio files that you don't want to load into memory, or for playback functions that don't require extensive playback manipulation.
- sfplay~ does supports variable speed playback, sample accurate cue looping and triggering, signal outputs for playback position, and correct playback of files with sampling rates different than the current sampling rate.
- sfplay~ supports the AIFF, .au, WAVE and Raw Data files. If you need to play MP3 or other file types, you may need to buffer~ and play~
