There may be times when your audio needs to be shorter to meet specific delivery requirements without losing any content. For instance, if your regular broadcast length is 45 minutes but your current audio is 50 minutes, you can speed up the entire recording. Here’s how to do it in Audacity.
Steps to Speed Up the Entire Recording: #
Step 1: Highlight the Entire Audio
Use the Selection Tool to select the entire audio track.
Step 2: Access the Change Speed Effect
Go to Effect > Change Speed.
Step 3: Adjust the Speed Multiplier
Use the Speed Multiplier slider or input field to change the speed. For example, set the speed multiplier to 1.5 for a 50% increase, which significantly shortens the audio length.
Step 4: Set a Specific Duration
If 1.5 times the speed is too fast or causes distortion, enter your desired final length in the provided field. Audacity will automatically adjust the speed multiplier based on the new length (e.g., from 1.5 to 1.073).
Step 5: Preview and Confirm
Click Preview to listen to how the audio will sound. If satisfied, click OK to apply the changes.

This method ensures your audio fits the required timeframe while maintaining the original content.
