Audio Speed Changer Pro 1.3

Audio Speed Changer Pro allows to change the speed of audio files playing.
This process is commonly used with audio books and podcasts, but it can be used with any sound file in which you want to change the speed or length.

For example, recorded speech that is included into a radio ad.

Audio Speed Changer Pro can modify any list of files saved under the most popular formats (MP3, OGG, AAC, MP4, M4A, M4B or WAV). It can modify four independent parameters: tempo, pitch, playback rate and volume. The interface shows a sliding control that shows the percentage that will be applied to the files you are working with. The program allows to preview how the settings you are using will affect the sound of the selected files. Once you are satisfied with your settings, you can order the program to save the sound files under any of the most common formats. At this moment you can choose where to save the generated files, normalize the volume and downmix the channels to mono. The trial version of this program will work with up to seven files at once, for thirty days.
