Your ears will often tell you if an audio file is not loud enough. If you crank up the volume and it's still too quiet, you may need to amplify the signals in your audio file. On the other hand, if a track is too loud you risk clipping, which sounds unpleasant. Also, if you have several tracks in an album or playlist, it can become annoying if the volume levels fluctuate up an down. Using our Audio Volume Editor, you can adjust each track so they play at similar levels.
It uses a decibel or percentage change to edit the volume of your audio files. If you want to double the volume, select "% Increase" and enter 100 for a 100% increase. Conversely, you can halve the volume by selecting "% Decrease" and enter 50 for a 50% decrease. You can also increase or decrease the volume by a set number of decibels you choose.
Decibels (dB) measure amplitude, which is the intensity of sound. The louder the sound, the more amplitude it has and therefore the more decibels it will register on the scale. Decibels are exponential, which means they rise at an ever increasing rate. For example, a 10dB increase results in a sound 10 times louder, whereas a 20dB increase results in a sound 100 times louder.
As a guide, normal speech is usually about 50dB, rock concerts about 110dB and a jet aircraft taking off is about 140dB. It's also important to note that regular, extended exposure to sounds above 85dB can result in hearing damage.
