Audio Speed Changer Pro is a free program that allows its users to change the speed of individual audio files without altering the pitch. In essence, this means that you can slow down or speed up files that contain singing or talking without affecting the vocalist’s natural voice. It’s capable of handling a variety of different files, such as MP#, WMA, WAV and more, and edits to audio can be done in batches for ease of use.

Edit audio speeds to your liking

Audio files contain more than just music, and for those that contain podcasts, audiobook or lectures, Audio Speed Changer Pro can help users listen to the quicker without affecting the speaker’s voice. In traditional audio speedup, voices and instruments are raised in pitch also, creating a chipmunk-like quality. With Audio Speed Changer Pro, however, pitch is retained and only speed is affected, giving listeners the ability to listen to audio faster or to slow it down for better comprehension.

More than just speed

Though Audio Speed Changer’s main focus is speed adjustment, it can also adjust tempo, pitch and playback rate. This can even be done in batch mode, and allows you to convert a number of audio files at once for faster processing. These adjustments, combined with a range of other features, makes Audio Speed Changer Pro the perfect free tool for easy audio adjustments
