[Csnd] ftaudio: docs, skip and multichannel

Subject[Csnd] ftaudio: docs, skip and multichannel
about ftaudio — which by the way works great. using 6.13 from git.

1) documentation: i-rate version of ftaudio, manual states:

	ians ftaudio ifn, "filename", iformat

but trying that yields an error. digging in entry.c and tabaudio.c seems to
indicate that the additional required sync argument is required. perhaps it
should be optional? in any case the documentation should be fixed.

2) could it be possible to specify a subsection of the table? right now i
manage by ftgen’ing a tmp table of the desired length and tableicopy'ing the
audio into it, which is OK to crop the “end” of a table but seems a bit like
a needless copy. skip + length would be great.

3) could it be possible to supply 2 (or N) table numbers to create stereo
(or mutlichannel) files? less of a priority than point (2) above, but would
be great and save time on post-processing.

thanks!
alex.

There is no sync parameter in the i-rate case and so te documentation is 
correct.  If the code des notwork that is differenr=t ad I would need an 
example.  Could you either open an issue and att an exampe or e-mail me 
the example?

I twill tink about points 2 and 3.  I think 2 is fairly straight forward 
with two optional arguments,.  3 is certainly harder.

I will look into 2, but I am not doing 3 at present s the mixer utility 
does that as I rememer
