[Audacity-devel] Patch for TruncateSilence effect

[Philip V. B. <pdv...@vi...>]

Attached is a patch for the Truncate Silence effect.

Changes are:

1) Can set a minimum and maximum silence duration, and compression factor 
for silence between these two values.

The resulting silence duration is determined as (output) = ((min) + (input - 
min)/compression) with the constraint that output < max

2) If the section starts out with silence, that silence will be truncated to 
the minimum value

3) Handles silent sections which span block boundaries

As an example, you can set the minimum to 100 ms, the maximum to 5000 ms, 
and the compression factor to 4:1, and it will have the result of about a 2x 
speedup in speech with no pitch change, and keeping about the same cadence 
as the original.
