This is a freeware that lets you change the speed of a particular MP3 track.
MP3 Speed is a tool that changes the speed of MP3 files and it is a freeware. Changing speed of a music track helps change the tempo as well as the pitch of the music track. If you did not want to change the pitch, you could do that too. This is a tool that really helps you become your own DJ. You are able to change the music playing and get renewed interest into old tracks that you have listened to many times. If you are into listening to audiobooks, speeding up the track will help reduce storage space as well as your listening time. What speed is the best for your listening pleasure or intelligibility can be set after you experiment with the speed for a while.
You can actually slow down the tracks too and make understanding of the words easier. Having decided the amount of slow down or speed up that suits your mood, you can process a batch of files that can use the parameters. The software tool will convert the tracks on the fly, there is no need for generating an intermediate form. The software should work quite fast, particularly if you have one of those multi-core and/or multi-threading processors on your machine. For creating the batch list, the software works with windows explorer like interface, you can drag & drop files to be converted into the work area quite easily. After the batch is finalized, you set the parameters such as if you want both tempo and pitch changed or just the tempo changed as also the speed up or slow down. You can choose an output folder other than the source, set sampling frequency, bit rate etc. Nice tool to have handy if experiments with the speed is needed.
