I have a _lot_ of audio files that have been generated by unusual
means. They are 32-bit little endian floating point, one channel, with
no header. I suppose this is some form of "raw." It's just a bunch of
floats, all audio.
I would like to be able to have them play by e.g. invoking QuickLook
on them or other similar means such as within DEVONthink. I don't want
to modify the file unless I absolutely have to, and then only by
automatic means (no manually opening in an editor and saving in
another format.
I'm pretty sure this is a stupid question, but is there some file
extension that I can add that will make the OS recognize them correctly?
My fallback is to save one file as AIFF and see how much bigger the
AIFF is than the raw--that is the header size and it is at the
beginning. I can read out that number of bytes and stuff them in to
the front of my file before I write out the floats, then add .aiff to
the file name. I recall having done this in the past (manually, for a
small number of files) and it worked for all similar AIFF files
regardless of lengths.
I know this isn't really a CoreAudio question but what better place to
ask. 8^)
On a related note, I used to have an OS9 utility that would tell me
the header length of AIFF files. Is there a tool around that does
this? Command line?
Thanks,
Lance
