MP3 Speed

MP3 Speed is a simple-to-use application that allows you to increase or decrease the speed of your audio tracks. It supports only the MP3 format.

The app is wrapped in a clean and intuitive interface; importing items into the file list can be done with the help of either the file browser, tree view (including or excluding subfolders) or 'drag and drop' method. Working with multiple entries at the same time is possible.

The file queue shows the name, location, type, tag version, metadata and other information related to the audio tracks. By accessing the 'Options' area, you can make the app change the tempo and pitch (or just the tempo), set the speed value, establish the output directory (same as the source files or custom), and proceed with the operation.

You can configure encoder settings in regard to the sample rate, channel mode and bits per second. Options can be restored to their default values. Other features of MP3 Speed allow you to rename files, remove duplicates, view file properties, as well as disable the tree folder in the main frame.

The audio processing tool requires a moderate amount of system resources, has a good response time, quickly finishes a task, and delivers sound files with a good audio quality. We haven't come across any issues during our tests; MP3 Speed did not freeze, crash or pop up error dialogs. First-time users can look into a help file.

On the other hand, it's not possible to play audio tracks after adjusting the speed and before proceeding with the conversion operation. This means that you could spend some time to perform several tasks, in order to get the results you want.
