Hello everyone, without much ado a few days ago PodCleaner version 1.2 came out, which has two major innovations:

  • A revamped user interface for parameter settings
  • A new file synchronization engine
New User Interface

To simplify PodCleaner main screen we decided to group all the settings of noise gate, equalizer and compressor in a single interface accessed by pressing the setup button:


This button opens this series of screens which, very similar to what happened before, allow you to set all the parameters in question.

These are the parameters of the noise gate:PodCleaner noise gate

These are the parameters of the compressor:PodCleaner compressor

These are the parameters of the pauses reducer:PodCleaner pauses reducer

And lastly this is the equalizer:

As you can see you can move from one section to another by clicking on the tab along the top.

The new synchronization engine

Much more important, in our opinion, it is the new audio tracks synchronization engine.

One of the biggest limitations of the earlier version of the synchronization engine was the fact that it was based on the fact that, more or less, all participants in the podcast would start at the same time to record, with a difference of up to 10 minutes:


Also if one of the participants, for some reason, was forced to stop recording and start again later, the synchronization engine would not be able to do anything:


These are two situations that, like it or not, sometimes occur when recording a podcast.

We have to thank Mario D’Amore because, for these reasons, I was turning on a light a few months ago when, within a single afternoon, we rewrote this engine.

It was not so difficult to modify the software, but I had to work a bit on the interface in order to manage these issues.


Setting the parameters of the synchronization engine

We make a new hypothesis: we recorded a podcast with three people, Alex, Cristiano and Leonardo, but there were two drawbacks: Cristiano has come to talk to us after 40 minutes, while Leonardo had a problem and had to stop his registration and start it again:


So we named our file as shown.

Let’s open PodCleaner and load the four files as indicated:

PodCleaner main screen

Subsequently click on this button:


It will open this new screen, which allows you to make additional settings to synchronization engine:


As you can see, just to the right of the name of each file, there are two columns with numeric fields, indicating a range of research and one that indicates the offset:


Search range

The search range is used to specify how much PodCleaner must move before and after, to test the compatibility of the files:


When you record a podcast and with a signal, all participants are starting the recording, almost in sync, we can leave the search range to a minimum: just a minute. For Podcast longer than five minutes this is absolutely perfect and allows you to achieve maximum synchronization.

We raise this value to five minutes when we’re not exactly sure that we all have pressed the record button at the same time, although it should be a more than rare.

Obviously we can set this value separately for each files, ie for every track.




But when a participant joins the podcast after a while ‘, for example, after about 40 minutes, we can set this thing in the offset field: in this field we specify that the track is related to a person who joined after that amount of minutes.

In our case Christian, who joined the podcast after 40 minutes, we indicate that the track has this offset:



Interrupted tracks

In the case of Leonardo, we have two files, which should be in some way “consecutive”.

I mean “consecutive” because the second files comes in some way after the first, after a pause of a few moments, of which we can not yet be certain.

What we need to do is specify on the right side of the interface that the second files “follows” the first: by setting this radio button:


This approach essentially says that the file 3 (the second part of the files of Cristiano) follows the  file 2 (the files of the first part).

In this way we are telling PodCleaner that the second files follows the first.

Also in this case we have to specify a search range, more or less wide depending on how long it took to Leonardo to restart the recording:


Usually this value is very low (one minute) when there has been an interruption but without restarting the computer, while we can raise it to three to five minutes if he had to make a reebot.


Final thoughts and next steps

As you can see PodCleaner is a project alive and evolving: we are working very efficiently to the next version, 1.3, which will introduce a number of bug fix and a new interface with a “wizard” to streamline operations to beginners.

PodCleaner 1.2 is a free update for all owners of previous versions.

I remind you that PodCleaner can be downloaded and used freely in all of its features for 15 days from the site PodCleaner.com.
