If one sound file has many frequencies between 1000 – 6000 Hz as shown in the diagram, it will sound louder. This is shown on the Fletcher-Munson curve below. Humans perceive different frequencies at different volumes. This may not be desirable, an example would be in mastering.Īnother problem is that RMS volume detection is not really like human hearing. This means that to make a group of audio files the same volume we may need to turn them all down so that none of their peaks clip (goes over 0 dBFS). We are still limited to the fact that digital audio can’t go above 0 dBFS. This method is closer to how the human ear works and will create more natural results across varying audio files.
It takes an average and calls that the volume. There may be large peaks, but also softer sections. This considers the “overall” loudness of a file. In digital audio you can’t get any louder than the highest peak at 0 dBFS, so normalizing to this value will create the loudest file you can. This is the best method if you want to make the audio as loud as possible. This only considers how loud the peaks of the waveform are for deciding the overall volume of the file.

We must first decide how we are going to measure the volume in the first place before we can calculate how to alter it, the results will be very different depending on what method we use. There are different ways of measuring the volume of audio.
What is the best method to normalize audio? Often normalizing audio just won’t work for matching volume levels, mastering engineers need not loose any sleep. While this is a huge advantage, it can’t replace compression as it can’t affect the peaks in relation to the bulk of the sound. Normalization can be done automatically without changing the sound as compression does.

It may be individual snare hits or even full mixes. Hope our suggestion helps to provide you with a better audio experience.If you have a group of audio files at different volumes you may want to make them all as close as possible to the same volume. If you wish to increase the volume of the files while playing, you can go with VLC, MP3Gain, etc.

Some of these apps, like Wondershare Filmora, Final Cut Pro X offers extensive audio editing features and audio normalization, which can be very helpful in video editing. Some people use it to play songs without having to adjust the volume for each song manually, others use it for enhancing the volume of songs that has a very low volume, and some others use it for video editing purposes.Ī list of applications with sound normalizers has been listed above, and you can choose any one of them depending on your purpose. What is the best audio normalizer for you?Īn audio normalizer can be used for a variety of purposes. From the General tab, tick mark the Normalize box, and the whole audio track will be normalized. Normalizing the audio using Movavi is very simple, and to do so, open the application and import the file first to the timeline.ĭouble click on the file on the timeline and click on Clip Properties. Movavi is a video editor with a very intuitive interface and a big collection of effects. Let us look at some of the best audio normalizers available in Windows. Normalization is still a useful feature that helps to equalize volume in different files. The performance of many audio components was limited in signal-to-noise ratio and dynamic range, and sound normalization helped. Top 10 Audio Normalizers for WindowsĪudio normalization was commonly done in the early days when digital audio was enjoyed. So make sure that normalization is done properly within the right limit. While the sound of the audio gets increased during audio normalization, the noise will also get increased. The other reason is to achieve matching volumes for different audio files. One is to increase the volume of a quiet audio file without making changes in its dynamic range for easy and better hearing. Sound normalization is done for mainly two reasons. In simple words, it can be defined as turning up the volume of an audio file without losing the audio quality. An audio normalizer is a tool that helps to change the overall volume of audio by a set amount to reach a predetermined level.
