Thanks, Hans, but iemlib/soundfile_info is also giving me the error.
soundfile_info_read-error:  /filepath/growl.oeoeoe.01.aif is no RIFF-WAVE-file

I was using soundfiler to load a sound into an array where I could play it back with variable speed. When I ran two of these applications simultaneously, I noticed audio dropouts every time soundfiler would load a new sound. Soundfiler is not threaded, so I went looking for other people's solutions. Someone mentioned that Miller had suggested using readsf~ in an upsampled subpatch to read a sound into an array quickly. When you do this, how do you know how long to make your array to load in the sound? I suppose I could just make a preset length. I did see posts about wavinfo (buggy) and soundfile_info (only for wav files).
