Levelator



I listen to a fairly large number of interesting podcasts. One problem is that the interestingness and the listening quality of the podcast are completely independent variables. That is, some of of my favorite podcasts are kind of painful to listen to because the volume levels vary all over the place - sometimes too loud, sometimes to quiet.

A company called Gigavox (producers of the excellent IT Conversations podcasts) has produced a new tool, Levelator, that fixes this. It's free and very simple to use.

It looks at an entire sound file and applies a number of corrections to the audio to make it sounds way way better. The image below shows the before and the after wave forms of an Olentangy Board of Education Meeting that suffers from uneven levels (the main problem is that different people sit closer or further from the microphones). You can see how much more regular the second waveform is from this.



This will go a long way to improve the sound quality of lots of podcasts. A welcome improvement.
