Adjusting the recording's volume level
Adjusting the recording's volume level
Are there any tools to balance the sound in mp3 files or a media player that dynamically adjusts volume only during soft speech, making the program louder when someone speaks more softly to match the volume of the speaker? Programs like mp3Gain or Sound Normalize alter the entire recording's volume rather than just specific moments. Many YouTube videos exhibit this behavior.
There are numerous audio editors capable of performing normalization. For instance, Audacity is a free tool that has gained significant popularity.

Online tutorials are also widely available. For example:

The simplest approach is to narrow the dynamic range of the whole recording, making everything roughly the same volume. This method is also referred to as loudness normalization or RMS level adjustment. You can apply this using Audacity or any other audio software. The key issue here is that adjusting the volume might make background sounds too loud, which could be a problem if the recording has almost no noise, like silence from an HVAC system. As mentioned earlier, another option is to manually trim and edit parts of the audio to increase the volume of quieter sections.
