Does protools include some automatic speech noise detection and/or removal
utilities?

I know these of course, not as an advanced user though.

It looks like you are talking about 100% manual noise removal. The users I'm
dealing with already do that on protools on Mac. They lose a lot of time with
this. I'm looking for a way to automate this, at least partly. I think they
really need this, so, if needed, I suppose I could convince them to use Ardour
for this specific task. In which case I'd try to code something to add this
feature to Ardour.

I suppose there is mainly two ways to do this:

1 - noise detection, manual removal (as mentionned by Dave on this thread). This
is certainly the most flexible thing, safest, and also the most language
independent. Because all selected regions could be removed at once it could also
provide a high level of productivity

2 - complete automatic removal. It would be more language specific (just think
about those tongue sounds in some african languages..), but may still work for a
certain range of European languages (I'm primarily targetting french).

The second solution has the advantage that it could be developed as a simple LV2
plugin or so, so that I wouldn't need to go and deal with the details of Ardour
editing routines, as in the first solution. I can't exactly tell how much work I
will be able to put into this, I might need to restrain my ambitions to stay
within some realistic professional requirements (read: money).

I like Rezound too, but the above remarks still apply.

Thanks. But don't forget this is a LAD question, and that I'm not afraid to code
(that's my job actually).
