Increasing the speed or tempo of an MP3 audio file using all the software I found from the Internet only mess the sound output.
To better understand, just imagine a sound being played from a Cassette tape or a Vinyl. When you increase the tempo/pitch, it outputs a sound like Chipmunks.
On a computer, e.g. Windows Media player, when you increase the tempo/pitch, it just skips frames. You will not hear it until you increase the speed. The sound will be like a choppy, skippy audio CD.
Now for my question, is there any software that I can download that will increase the speed of my MP3 output by doubling the the framerate/sec instead of removing some frames from it?
Thanks you so much!
