How to Change Audio Speed / langth Without Changing Pitch
By default, the tool preserves pitch while changing speed.
That means you can make a voice recording, podcast clip, music track, sound effect, or practice file faster or slower without making it sound artificially higher or lower.
You can also turn pitch preservation off when you want the pitch to change naturally with the speed, similar to speeding up or slowing down a record or tape.
