How to reduce WAV file size

Updated July 20, 2017

You can reduce a WAV file size by converting it to a smaller, compressed audio format such as MP3. A typical compressed MP3 is approximately one tenth the size of a full quality WAV file and can sound comparable to the original WAV file’s audio quality.

Open iTunes and click on "Preferences."

Click “Import Settings” and select the “MP3 Encoder” from this menu.

Click “OK” once you’ve made your choice and then click “OK” again to exit the Preferences menu.

Import the WAV file that needs to be reduced in size. Do this by dragging and dropping the audio file into the iTunes library. Click the WAV file, select “Advanced” and click “Create MP3 Version.” iTunes will then reduce the WAV file size by converting it into the compressed MP3 audio format. When finished, this compressed file will appear below the original WAV file.

Open Switch and click “Add Files.”

Select the WAV file that needs to be reduced.

Select the ".mp3" audio format from the “Output Format” menu to compress the WAV audio file.

Choose a folder in which to save the reduced file by clicking the “Browse” button next to “Output Folder.” Then click “Convert” and Switch will reduce the WAV file size by converting it into a compressed MP3 audio format. The compressed file will be exported from Switch and saved in the “Output Folder” you selected.

Open dBpoweramp and click “Browse.”

Select the WAV file that needs to be reduced.

Select the "MP3" audio format from the “Converting To” menu to compress the WAV audio file.

Choose a folder in which to save the reduced file by clicking the “Folder” button next to “Output Location.” Then click “Convert” and dBpoweramp will reduce the WAV file size by converting it into a compressed MP3 audio format. The compressed file will be exported from dBpoweramp and saved in the “Output Location” you selected.
