Lines: 26 I'm not much of an in-depth Toolbox person, but I'd appreciate if someone could help me sort this out... I recently got the freeware SID (Sound Input Device) disk from Educorp, which describes hardware and C routines for recording sound samples and manipulating them. It turns out that Cedar Technology (617-623-3563) sells a kit for $45 to build the microphone + A/D converter hardware (with a few changes from SID's design), which I assume is reasonable compared with commercial offerings(?). What I want to know, however, is whether Apple's recent Sound Input Manager (new Toolbox routines?) makes SID redundant. In any case, are these approaches compatible in terms of the format with which sounds are stored to disk for editing? I read recently that Farallon has had to modify their SoundEdit utility to be compatible with the Sound Input Manager routines... Thanks for any help you can give me! Incidentally, the thing I want to do is to write routines which perform Fast Fourier Transform analysis on the sound samples, for measuring frequency response, etc. Regards, Ralph (rgonzal@elbereth.rutgers.edu)
