The short version- Check whether the peaks reach the top, or whether the average level is high.
- Lower the level to a loudness target, not by eye.
- Check the true peak after the change.
- Listen on a phone speaker, where too-loud recordings are most obvious.
Peaks or average?
A file can be too loud because its peaks clip, or because its average level is high and the voice is pushed. Look at the waveform for flat tops, and measure the loudness of the whole file.
Lower it to a target
Set the file to a loudness target for where it will be played, rather than lowering it until it feels right. The loudness guide lists the targets people use.
Check the peaks
After you lower the level, check the true peak. A file that is quiet on average can still have high peaks, which a phone will play harshly.
Listen on a phone
Play the file on the phone you will use. Adjust only once you have heard the result on that device.

Frequently asked questions
Should I lower the file until it sounds right on my phone?
No. Set a target and check the peaks, so it sounds right on other devices too.
Why does it sound loud on my phone but not my computer?
Phone speakers can exaggerate peaks. Check the true peak as well as the level.
Does a limiter fix a loud file?
A limiter controls peaks. For an overall level, set the loudness target first.
