loading sf with amb header

Hello,

can any write about loading unrecognized file types into sfplay. I am
particularly interested in the Ambisonic .amb extention. I have tried
loading them as a raw header, but to no avail. Any information is
appreciated.

running mac osx

thanks,
Charles

AFAIK .amp is a hack to make WAVE_FORMAT_EXTENSIBLE files be openend
by something else than WMP (on windows).
they’re basically WAVE files with an additional header describing the
order of bformat-channels (i.e. a special GUID).

see the sursound-list archives for more details and refer to http://
http://www.ambisonicbootlegs.net,
i think this is the guy who defined the format. see also:

format/

changing the extension to .wav makes it a normal soundfile on Mac OS
X, but sfplay~ still balks at the file.
(poss. c74 feature-request).

I know why I suggested to use a wellknown aiff format instead of the
widely unknown wav extension, but nobody wanted to listen…
PC people think micro$huft is the only standardisation comitee…

Should be a feature request, to make sfplay~ multichannel.wav aware…

I agree precisely on both counts.
