Re: Soundtrack AIFF extensions & compatibility

Thought I'd just post my own reply for posterity... I went through dts and got confirmation that the AIFF extensions for Soundtrack are not public information. Like other "mystery" chunks they should just be ignored. To generate transients it looks like one has to go through the Loop Utility app. I guess for a semi-lame implementation a loop-creation/recording app could just save an AIFF file and then have it open in the Loop Utility (with AppleScript) and save it again. If anyone with the ear of the Soundtrack designers is listening, please consider it a feature request that you provide some way for audio editing applications to add the Loop Utility data to AIFF's. An AppleScript dictionary would be tolerable, a LoopUtility.framework would be awesome. I don't see exposing this functionality as doing anything but encouraging more (and more extensible) use of Soundtrack. Not sure whether doing something like setting AIFF markers might help hint the Loop Utility - I'll experiment a little and post again if I find anything useful. - Chris On Dec 1, 2003, at 2:11 PM, Christopher Corbell wrote: I'm new to the list and don't see an archive listed at search.lists.apple.com, apologies if this has been covered before...

In scanning a Soundtrack loop AIFF I see several undocumented chunks, such as 'trns', 'cate', 'basc'.

Is any information available at this level? Also are other AIFF mechanisms honored by Soundtrack, e.g. if my app is rendering a MIDI sequence to AIFF and knows where the beats are, can I use marker chunks to give Soundtrack a hint on beat locations, or does Soundtrack only look at the publicly undocumented 'trns' chunk? FWIW the apps involved are iPiano, to which I'm adding improved AIFF export including loop-segement export with sequences using any SoundFont/DLS bank sounds, and a new Cocoa AudioUnit-host/audio-editor that's in early stages of development.

I wouldn't draw that conclusion yet. There simply hasn't been much traffic on the list yet. I joined this list too late to see your previous post, but upon searching the archives I found this one: > LiveFont Development: Since there is NO LiveFont around that is not > built > with the exact values that the demo font gives away... In fact there are lots of LiveFonts built with different values. Are there really any that just use the demo values? That would be odd. Some third-party LiveFonts can be found at the following links: <http://www.livetypecentral.com/> <http://www.screencaffeine.com/> > ...(without documentation of the values used). I'd like to have a > proper documentation to build a REAL LiveFont not just ripped copies > of existing fonts with bad metrics. I'm not sure what you mean by "proper documentation." Are there some particular FontScript commands that are unclearly documented in the LiveType manual, or is it a more general thing? Granted, some of the metrics like the pivot point and anchor point may require some trial and error, but once you've got the first couple of glyphs figured out, the rest should go smoothly. If you have any more specific questions, I may be able to be more helpful.

Hey there! Just wondering if anyone ever got a reply from Apple on or off this list?

Soundtrack AIFF extensions & compatibility
