Audio editing order: trim, normalize, then merge
A two-minute voice note, a sound for a small game or a set of recorded intros rarely need a studio editor. They do need a sensible order of operations, because the same steps in a different order produce a quieter, clipped or uneven result.
Trim before you normalize
Trimming decides which part of the recording is the material. Normalizing then sets the peak level of that material. If you normalize first, a single loud click or cough can set the peak for the whole clip, and every actual spoken word afterwards sits lower to compensate.
Listen to the join point after trimming. A hard cut in the middle of a breath or a word can be more distracting than the length you saved, so leave a little room around the intended selection.
Peak level is not perceived loudness
Normalizing raises or lowers the highest point of the waveform to a chosen level. It prevents the loudest moment from clipping, but it does not make two recordings feel equally loud. A voice and a music bed with the same peak can still sound very different.
For a short clip, use peak normalization as a safety measure and judge the result by listening. Turning up a quiet recording that already has background noise also turns up the noise; there is no setting that removes the hiss.
Merge compatible clips only
Merging samples the clips onto a common rate and channel layout. Clips recorded by the same device usually match; clips from different apps may not, and a mono announcement joined to a stereo bed will either be widened or force the whole result to mono.
Browsers decode supported formats in their own way, so export always becomes a new WAV. That is a working copy, not a smaller file: the same content in WAV takes far more space than a compressed source did. Compression belongs at the end, with a separate encoder, and never on a file you will edit again.
A short audio routine
- Duplicate the source file before editing
- Trim the selection, listening to both ends of the cut
- Normalize after trimming and listen again at normal volume
- Check for clipping at the loudest syllable, not just at the end
- Merge in intended order, then label each segment in the export name
- Keep the exported WAV as the master and compress a copy for publication
