In cases where you need more audio volume, you can use compression to go beyond what you could do with a normalize effect only. Therefore, if your audio volume peaks at -1dB you can only increase your overall audio volume by 1dB without introducing distortion and that may not be enough if you have a quiet audio recording. However, if you have sudden spikes in volume normalize effect might do very little to increase overall audio volume because it increases the whole audio recording by the same amount of volume. Normalize effect is great if your audio recording is even, such as in this case. In the example above, after applying the effect my average audio volume (RMS) increased by 5dB (from -33.9dB to -28.9dB). Audio track volume after applying Normalize effect (RMS -28.9dB) Normalize effect settings and audio track before applying Normalize effect (RMS -33.9dB). Don’t go over 0dB as that will create audio clipping and will cause distortion unless that’s what you want. In the effect settings menu select a peak volume of up to 0dB. You can increase audio volume by selecting the whole audio recording and applying a normalize effect. Audacity is my favorite free audio editing software but any will suffice. Increase audio volume with Normalize effectĪny audio editing software will have an effect called Normalize. As a quicker alternative with some limitations, you could use online tools to increase audio volume in a few clicks. To increase audio file’s volume you’ll have to use a tool called normalization and if that doesn’t suffice you can further increase audio volume by compressing it which makes your audio more even allowing some room to further increase its overall volume (RMS). Rather it could introduce a new problem – audio distortion. You can always add some volume in audio editing software but quite often you’ll find yourself in a situation where simply increasing audio volume doesn’t work. For every audio recording, there’s a limitation of how loud you can go until the microphone starts creating a distorted sound.
