Audio Pitch Directshow Filter Description

Generally speaking, the role of the audio pass filters is to help attenuate the entire range of frequencies of the audio sample. As the name suggests, Audio Pitch Filter is a powerful filter that enables you to modify the audio tempo and pitch of your videos effortlessly.

It is important to note that the utility works with any video and audio file that can be played in any Directshow base application, including but not limited to Delphi, .NET Framework, VB or CV++. The tool comes with a sample GUI that permits you to select and playback the sample before you make any change.

The highlight of the utility stems from the fact that you can stop and pause the media file at any time as well as make the modifications while the file is running. Increasing or decreasing the pitch can be done with just one click by moving the cursor on the dedicated bar. Unfortunately, the approach is rather rudimentary as it does not allow more precise or minor changes.

As far as the audio tempo is concerned, you can speed it up or slow it down via the buttons included in the GUI sample. In case you change your mind, the tool enables you to restore the parameters to default.
