How to change audio duration without changing pitch
By Sodaphonic · Updated
Use Time-stretch in Sodaphonic to fit a recording to a new duration while preserving pitch. Compare it with Faster and Slower effects.
Steps
Load your audio in the editor and choose Effects → Time-stretch.
Enter New duration (seconds). The dialog shows the current duration and permits a target between half and twice that length.
Wait for the processing tool to load, then press Stretch.
Listen to the result. Try changing a 10-second clip to 9 seconds before making a more extreme adjustment.
Use Undo to compare another duration, or File → Export to download the result.
Tips and examples
Time-stretch changes duration while aiming to preserve pitch. Faster and Slower change playback speed and pitch together. Large changes can introduce audible artifacts.
Time-stretch needs a secure browser context and downloads its processing engine when needed. If loading fails, check the connection and try again.
