Hi Danijel,
I'm not sure I understand this whole system. I assume
you want to build a software app that listens to speakers and analyzes
characteristics of their voice to determine if their spoken sound quality
is like natives. If this is what you're building, you will need a
classifier for

You will likely compare in feature domain and that depends on the kind
of features you use. You need some heuristics for determining how close a

I think you would analyze in feature space, where the features are
intermediates in the speech recognizer that you got off the shelf, what
are the patterns that you associate with the speech of a small class
of native speakers. This would be one way to define
native-ness. Then you would

Thanks for all the input, everyone. Just to follow up on the original
question. In the end the compressor built into SoX satisfied my needs for
scripted processing of audio signals. In particular, it was able to handle
really fast attack times and remain surprisingly transparent.

Sinc interpolation would be theoretically correct, but, remember,
that this thread is not about strictily theoretically correct frequency
recognition, but rather about some more intuitive version with the
concept of instant frequency.
What is instant frequency? I have to say that I find this
This post explains the concept instantaneous frequency well: (It is basically
used to distinguish amplitude from phase)

I guess my point is that I'm struggling to think of an application where
such strong prior knowledge exists, and where we'd still need to estimate
frequencies from data.
One such application would be a CV to controls(Midi,OSC,whatever) converter. As
virtually all the soundcard inputs are AC
