Make speech or music smaller by choosing a level that fits the type of content.
When this guide is useful
Speech recordings usually tolerate more reduction than music with complex detail and a wide frequency range.
Think about where the file will be used. Messaging, social media, websites, presentations and archiving can require different sizes and formats.
How to decide without overcomplicating it
For messaging or email, start with moderate compression and listen before reducing the size further.
Always start with a copy of the original file. That gives you a reference and lets you try another setting without losing the best-quality source.
How to check whether the result is good
Make a first attempt with moderate settings. Then review the full result, especially areas with small text, faces, music, transitions or fine detail.
