[SoX-users] Real-time input buffering

[<aa...@bo...>]

   I have an application which analyses an audio stream
on the fly.  (You could say real-time).
The analysis can have varying processor load, depending
on the content of the audio stream.

    I CANNOT loose ANY audio data.  However, when processing
gets behind, I need to be able to BUFFER incoming data.
Its OK for my processing to get several SECONDS behind the
real-time stream, but I cannot just dump audio samples when this
happens.  I need to buffer them up, and have the analysis catch up
to the real-time stream later.

     Can anybody provide advise about how to go about this.
Can I use SOX?  Can I modify SoX (make large input buffer?)
to handle this?   Can I learn how to do this from the SoX source?
Should I be looking into Real-Time linux extensions to maintain
a LARGE circular buffer of incoming audio data in Real-Time/Kernel space
shared memory?   If so...  any suggestions about where to learn
about this?

    SoX must have SOME buffering in order to be able to operate
under -t ossdsp.  How does this work?  Could my problem be solved
simply by increasing the size of this buffer?
