How to Quickly Reduce Gaps Between Sentences using Truncate Silence in Audacity

Slow talkers, guests who compose their answer before speaking, and what I call “Skype Lag” can leave long pauses between the conversation in a podcast.

What's a long pause?

Well, I consider a long pause a gap between sentences that lasts longer than necessary – usually a second or more.

1-second gap between sentences (Truncate Silence)

 

Truncate Silence in Audacity

Use Audacity's Effect > Truncate Silence​ to compress any gaps longer than a set length.

For example: Compressing any gap longer than 0.4 seconds by 60 percent.

Applying this effect is a quick way to tackle the entire project without reducing gaps too much:

Applying the Truncate Silence effect to the entire project in this manner is pretty safe.

It tackles any gap greater than 0.4 seconds to 60 percent of its original length.

  • A 1.0 second gap turns into 0.6 seconds
  • A 0.5 second gap turns into 0.3 seconds
  • But a 0.3 second gap is less than the 0.4 seconds Duration you set, so it safely remains at 0.3 seconds

You can apply this effect quickly to a small portion of your podcast or to the entire project at one time.

 

When Silence Serves a Purpose:

It would be unreasonable to cut all pauses from an interview or podcast conversation. In comedy, timing is everything.

Silence can serve a purpose:

  • For dramatic effect
  • When someone is contemplating the answer to a very important question
  • During a meditation demonstration (listen to the [33:33] mark of this podcast)

However, when the above situations aren't met then I cut them down to something more realistic – and more comfortable for the listener.
