Hi folks,

I am on this list to be able to closely watch the progression of the
OBOS MediaKit because I am developing an audio editor for
this OS. ( www.xentronix.com )

Now I have two points / questions:

Does anyone can explane / show the working of the media_format a
bit more ?? I need to be able to decode any selected file to native
supported B_AUDIO_FLOAT.
SampleStudio works with 32bit floats internal as BeOS does, but I now
only am able to decode to the bits of the source-file and do the conversion
to floats by hand.

Same goes for saving. I can not get any descent info on how to select a
save-format and save the internal 32bit float buffer to any selected format.
(like 16bit WAV or MP3 ....)

Next point:

As OBOS needs addons for reading and we would like to extend the set
of supported formats with some proffesional formats of some samplers,
I was wondering if any of you have info on how to write such a decoder / 
encoder addon ???

I am willing to do some of the basic formats for OBOS as the basic version
of SampleStudio will be freely available and probably included in the 
BeUnited package, we could do some of the work in this area for you.

Maybe anyone has an example encoder/decode addon ??
