2024 Approved 10 Best Free Online Audio Normalizers

10 Best Free Online Audio Normalizers

What is Audio Normalization, what are its different types, why do we need it and how to do it online? – these are the questions we might ask when first learning about it. Well, then, let’s answer all of them!

Audio Normalization means that the loudest parts of an audio signal are set to a specific value. For example, -18 dBFS (decibels relative to full scale). This is done so that all the parts of the sound mix remain at equal volume levels.

You can use this tool when mixing or editing your music, or during playback on your speakers. In the case of mixing, listen for any clipping (A form of waveform distortion - It sounds like the audio is starting to ‘break up,’ which is light distortion. The more severe it is, the more distorted the music begins to sound) that could occur in your mix. So, in this case, you need to normalize before it becomes too loud and needs more and more fixing. So, normalizing the audio kind of means balancing the volume of the track.

Mostly, audio normalizers are used for balancing out the volume of music, podcast, or other audio recordings. Whenever you have a variety of audio clips that would sound too loud or soft if listened to together, an audio normalizer helps you create a more cohesive listening experience. So, why, and when, do we need to normalize our tracks?

To make different music styles sound more cohesive;
To adjust the volume of podcast to be at a consistent level with one another
To remove sharp spikes in volume for consistent listening experience for our audiences

So, what are the types of audio normalization? Here you have it:

peak normalization - helps adjust the recording based on the highest signal level present in the recording;
loudness normalization - adjusts the recording based on perceived loudness;
RMS (Root-Mean-Square) - changes the value of all the samples, where their average electrical volume overall is a specified level.

So, say that if you are a creator and have listeners, with this tool, you can count on the expectation that people will more likely want to convert to being loyal subscribers, viewers and listeners. This is what happens when audiences feel their user experience is favored and they enjoy a good content – it makes them come back for more.

But sometimes you don’t have so much time that would allow you to find a software, download its installer, install it, learn how to navigate inside its interface, which might be totally new and in some cases, complicated for you, and learn how to normalize your audio files there. In this case, you might want to find the right tools which would enable you to reach your goal without even having to install anything – simple and fast!

Hence, for this case, we would like to offer you the list of 10 best free online audio normalizers. The list goes:

MP3 Gain Volume Changer
Sodaphonic
Audio Mass
Audio Online Convert
Audio Editor
fConvert Online Converter
Boost MP3 Volume
MP3Cut Change Volume
Audio Alter Volume Changer
Audio Trimmer Volume Booster

Therefore, let’s delve into each one of them, and learn how to use those online editors in our favor!

MP3 Gain Volume Changer

This online editor allows you to adjust the volume level of MP3 audio files fast – it can raise, lower, and normalize the volume level of your MP3 files.

The interface is simple and easy to use – exactly what you must be looking for. You can adjust the volume level to make the MP3 the way you want to listen to it.

One of the important things this app is letting you do is to upload from Google Drive or Desktop – it works locally without going through a server, and this means that MP3s do not need to be uploaded to any server.

So, go to this link . Click on Choose Files and find the audio clip you would like to normalize.

Now, once your audio track is added, head a little below and find the options you have.

Here, you can decide what do really do with your file: do you want to increase or decrease the volume? If you choose automatic normalization, the app will figure something out itself! And, look at the right side – in case you know well your decibels, you can choose how many decibels to apply. But the web-site itself says that 3.0 decibels is recommended, so it would be nice to just stick with it.

If you have multiple files and you want to normalize them all at once, click on Create MP3 (All); in case you have a lot of files and you would like to normalize one or more of them but not all, then your best choice would be Create MP3 (Selected). Another option is that you save your file on Google Drive.

When you Create your file(s), the normalized one(s) will appear under those buttons in Progress Log, and you can Play right away, or Download and listen to it later on.

Sodaphonic

Sodaphonic also lets you edit your audio files online. With the help of this editor, you can cut, copy, and paste sound segments of an audio. It offers you: normalizing audio, using audio effects, time-stretching, reversing audio, fade-in and fade-out – those tools are really helpful.

Sodaphonic is pretty interesting as the first thing that meets the eye is that it lets you not only pick or drop an audio file there, but record something new, too!

Any option you choose, then when proceeding into the editor, you will see your file waveform there. In order to normalize the audio, on the top left, find Edit, put a cursor on it, and you will see the menu appear. Find Normalize and click on it.

A little window will appear, where you need to fill in how many decibels should be set as the max peak.

Once you do this and click on Normalize, your file will now be affected, and you can also compare the waveform – it is now a little different, isn’t it?

So, when you are happy with the result, just go to File, and Choose Export.

Audio Mass

The Audio Mass editor will help you edit audio and waveforms over the web. There, you can load any audio format your browser supports, and apply many different audio effects (fading in, cutting, trimming…)

So, Audio Mass lets you: normalize audio, analyze frequency, signal distortion and peaking, trim, past, cut audio segments, reversing and inverting audio, convert to MP3, change of volume levels, fade in and fade out, audio compressor, adding reverb, delay, distortion.

When you go to the web-site , you can choose your desired file right away and the site will open it in a waveform. Now, the Normalize option is in the Effects (in the menu on the top). Click on it.

The window opened will show the option to Normalize Left and Right Equally, and it also doesn’t give you decibels – instead, you can choose the percentage on how you would like it to be normalized.

Then, surely, click on the Normalize Audio button and enjoy the result – the waveform itself will show you how different the file becomes…

So you’re all set: you’ve sat down, grabbed your microphone, fired up your recording software, and started pouring out the content of your mind. Once finished, you listen back to the recording, thinking you’re about to hear the silky-smooth undertones of your voice resonating through your ears, but something odd occurs — it sounds terrible. Distorted audio is very unwelcoming since you want the sound to be natural. This guide will explain how to fix distorted audio using various methods.

What Causes Distorted Audio?

Distorted audio is the main culprit in ruined audio clips. Here are some of the causes of distorted sound.

1. Recording Environment

Not recording dialogue and voice-over in a studio can cause distorted audio. However, audio quality can be out of control if you conduct an onsite interview. Getting a meaningful and cinematic shot should come first. If you do not use a studio-quality microphone that comes with directional controls, you’ll likely have distorted audio. You might want to go for a unidirectional stereo channel if you want boom movements to be undetectable.

When a cheap, low-quality microphone is moving, you’ll hear the unsteadiness in your recording, leading to distorted audio. Recording audio in an echo chamber or an overly large room can also result in distorted audio.

2. Touching the Mic While Recording

If you hand the microphone to someone who does not know how to use it, they might hold it too loosely or close. Microphones feature sensitive parts that should not be dropped, shaken, or breathed on. When you are interviewing people unfamiliar with industry standards, you should hold the microphone, not the person you are interviewing. The mic is not within the range of 6” to 12 “ away from the speaker, this could lead to distorted audio.

3. Using the Wrong Mic

A reliable mic comes with audio controls and captures room tone and timbre. It should be portable, compact, and have a wind sleeve. In outdoor situations where ADR is not an option, you might want to use a wind sleeve.

Podcast showrunners and content creators often use Blue Yeti mics connected to a soundboard. While these are cheaper options, they can cause distorted audio. Content creators who are not stationary should purchase a lavalier, and wireless is a more high-end and expensive option.

4. Positioning Your Microphones Incorrectly

You have to be careful if you’ll be mounting a mic on your DSLR. Filming events with a one-mic setup is a promise to record everything you hear again. You’ll inevitably film some moments at a distance and leave the audio compromised to distortion.

5. Faulty Equipment

Your equipment can fail in different ways. For instance, your effects processor can fail, meaning that you won’t hear any sound passing through it. It can also fail, and you end up hearing a distorted sound passing out of the processor. Essentially, this might or might not be linked to the component’s capability of handling the signal as much as the busted internals result.

How To Fix Distorted Audio Using Different Methods

You can fix distorted audio using various methods. They include:

Method 1: How To Fix Distorted Audio in Audacity

Audacity is the bread and butter for individuals who adore a crisp audio quality. Audacity helps users finetune various attributes of their recordings. It is a free and intuitive software suite suitable for newbies and individuals who don’t interact with computers. With that in mind, here is how to fix distorted audio using Audacity.

Open the audio file by dragging and dropping it into Audacity.
Select the distorted part and click on the Effect option. Then, select Noise Reduction.

The Noise Reduction window will open.

Now, click on Noise Profile, and Audacity will know what to filter out.
Next, select the entire audio and open the Noise Reduction Window again (Effect > Noise Reduction). Then, set the values to suit your preferences.
Hit preview to check the audio, then the Click OK button.

If the audio is still distorted, apply the filter again. Don’t overdo the process numerous times to ensure your audio is not degraded, making the voice sound robotic and tinny.

Now, use compression to your advantage. If compression confuses you, think of it as a tool that adjusts your audio for the listener’s benefit. Compression not only quiets the background minutiae that creeps into your recording, but it also boosts your voice and gives it a full, captivating resonance.

To start the compression process, select your audio track, press CTRL + A, click “Effect” and then click “Compressor.”

Adjust the values in the compressor to meet your needs and make your voice “pop” from the background.
Once you have set the values, hit the Preview button to check the audio. Then, click on OK.

That is how to fix distorted audio using Audacity.
