Writing to SDIF in realtime help please.

March 21, 2007 | 6:34 pm

Hi,

Perhaps I’ve missed something in the cnmat spectral tutorials or the FTM help files but I can’t find a way to do this, can it be done?

I’ve tried the ftm record object but it doesn’t appear to accept audio input. What I want to do is to record incoming audio as sdif in discrete chunks, any suggestions…?

thanks,
Scott

the ftm.sdif.write object writes incoming data directly to an SDIF file,
frame by frame.

You have to produce the data to be written yourself by analysing a sound
stream, e.g. using the gbr.peaks and gbr.trace modules, when you want to
do real-time additive analysis.

Hi Scott,

With FTM you’d need to use gbr.slice~ to make vectors from the signal.
