Time stretching is a digital audio processing technique that allows you to change the speed or duration of a sound without affecting its pitch. For example, if you have a song and want to make it longer without altering how high or low the notes sound, time stretching can help. This is useful in music production, where artists often need to fit sounds into specific time frames. In addition to music, time stretching is also used in film and video editing. It helps synchronize audio with visuals, ensuring that dialogue matches the actors' lip movements. Software like Ableton Live and Pro Tools often includes time stretching features, making it easier for creators to manipulate sound effectively.
