Measuring Volume within Audacity

It is helpful to know whether your volume is correct before exporting to MP3. There is a plug-in for Audacity called ReplayGain which allows you to do this.

The latest version of ReplayGain.ny both analyses and has the facility for Equal Loudness Normalization (i.e. amplifying to the required level), and appears in the Effect menu in versions of Audacity 2.1.0 and later.

There is an earlier version of ReplayGain.ny which analyses the volume only and indicates by how much you need to amplify + (or de-amplify -)to achieve the desired volume of 89 dB. This version appears in the Analyze menu in 2.0.3 and in the Effect menu in 2.1.0.

The author of this plug-in (these plug-ins) explains in the Audacity forum here.


Amplifying


Levelling


Dynamic Range Compression


Manipulating Tracks


De-Essing Files

Removing Click Sounds

Fixing Individual Plosives

It is (obviously) better to avoid getting them in the first place by correct mic placement. See this article.

However, the occasional popping 'p' (which is actually breath on the mic and a very low frequency sound) can be isolated and treated with a High Pass Filter. Make sure your selection begins and ends on the horizontal line (by clicking the Z key). Then click Effect > High Pass Filter, and using settings of roll-off 12dB and cut-off frequency 100 Hz, click OK. The popping sound should be decreased.
