Audacity Loudness Normalization: Make a Voiceover Series More Consistent

Audacity offers two useful but different controls. Normalize targets peak amplitude. Loudness Normalization works toward a perceived-loudness target. Matching the tallest peaks alone does not necessarily make recordings sound equally loud.

Start with the delivery requirement

Before changing levels, check whether your client or publishing destination specifies a loudness target. Write down that requirement alongside the requested file format.

Avoid choosing a number simply because another creator uses it. Audacity’s documentation notes that loudness requirements vary by application. Its displayed default should not be treated as a universal target for every video or podcast.

For your own series, choose a consistent review process: keep the original recordings, prepare working copies, and compare finished episodes at the same playback volume. Include an ordinary spoken section and a more energetic passage in your comparison.

Apply the appropriate control

Once the main editing is finished, select the audio you intend to process and open Effect → Volume and Compression → Loudness Normalization. Choose perceived loudness and enter the target required for the job.

For an already balanced stereo recording, leave independent channel normalization unchecked so both channels receive the same level change. If you are processing mono, check the “Treat mono as dual-mono” option against the measurement workflow you need; it can affect comparisons with other loudness meters.

Check peaks separately

Loudness and peak control answer different questions. Audacity’s Limiter constrains stronger peaks above a chosen threshold. If your delivery specification includes a peak ceiling, review that requirement as well rather than assuming a loudness target covers it.

Make the export part of the review

Export a test file and open it in the player or editor you will actually use. Listen to the beginning, transitions and loudest passages. Then compare it with another finished item from the series without moving the playback-volume control. If the handoff specifies measured loudness and peak limits, check both on the exported file with a suitable meter; listening alone does not establish that it meets those limits.

Keep a short handoff note recording the target, mono or stereo format, settings used and any unresolved issue. That gives the next episode a repeatable starting point.
