I couldn't find a way to do this in ecasound, maybe there's a way to do 
it. Here's what I want to do:

Find the exact length of a audio file in ms. I think ecalength can do 
this, I know it's not sample accurate, but I just need down to the 
around 1ms. Maybe there's another option other than ecalength.

Then, I want to extract a section of another file: at a specific 
location in ms at a length of the file above.

Then, mix that extracted segment with another file and save the result 
to a new file.  How can this be done? I don't know of a utility that can 
extract a specific length at a specific location in ms.
