Tricks to improve the audio quality of audacity recordings

Audio is one of the elements that we most commonly use when talking about multimedia content, where we also include videos or photographs. But focusing on sound, the truth is that working with MP3 files is something that has spread a lot, for which Audacity will be of help.

Sometimes the sound quality in MP3 or another format that we listen to regularly may not be ideal. In order to improve it, we must use a professional tool that can help us correct it.

Audacity the most popular free sound app

We already refer to the audio files that we create with music, voice recordings, or sounds of all kinds, these contents can already be edited in many ways. For all this, at this time we can use several specific tools, many of them free. However, one of the most popular is Audacity, a free application that we have already talked about on some occasions in the past and that you can download from here .

That is why for all those who want to edit their audio files in MP3 or any other format, this will be a great solution. In fact, many users use the program to cut parts of the audio tracks, edit personal recordings, join files, normalize their volume, etc. At the same time, this application offers us some basic functions that will be of great help to us in these tasks.

For this reason, below we will talk about a series of tricks with which you can improve the sound quality of your recordings from the aforementioned Audacity .

The importance of sound hardware on the PC

Of course, all this that we are going to talk about next refers to the improvements that we can achieve at the software level. But all this would be much more complicated, if not impossible in some cases, if we do not have adequate hardware for our needs or requirements. With this, what we want to tell you is that whether the sound file is your own, as if it belongs to others, it is most recommended that the capture has been made in optimal conditions.

Elements such as the sound card that we have installed in the computer come into play here, such as the microphone used to capture the signal. In addition, this has to be carried out in a suitable environment, without background noise or distortion. Once we have fulfilled this that we are commenting on, we can now use the software that improves the signal that we have just captured or received from another user. But if this is not true, the software alone cannot work miracles, no matter how advanced.

Improve the audio of your MP3s from Audacity

If we want to improve the audio quality of our music files with Audacity, here are some tips that can help you achieve this.

Amplifies certain parts of an audio track

It may be the case that some parts of the recording or sound file are heard too low in relation to the rest. Therefore Audacity can help us in all this in a simple way. The first thing we must do is load the audio file as such in the application. Then we mark the part that is heard too low with the mouse pointer, over the signal of the track that appears on the screen.

Once that part is marked, we just have to go to the “Effect” menu and select the “Amplify” option. Here we will be able to specify the level of increase of the decibels for that part of the audio in particular.

Eliminate background noise from your MP3s

Another of the most common defects in audio files is the popular background noise that is sometimes generated. These are normally created if we are making a home recording, either music or voice, which can become a problem. Therefore again we can use Audacity to make all this work and we can eliminate that annoying background noise.

As in the previous case, the first thing to do will be to mark with the mouse the part of the track where we detect the noise, so we highlight it. Next we go to the menu “Effects / Noise Reduction”. Here we click on the “Get noise profile” button so that the program starts up and eliminates that annoying background noise by itself.

Eliminate distortions from your recordings in Audacity

When we work with these audio files, we can also find certain parts that sound distorted, something for which the application that we are going to talk about will also help us. To do this, once we have the track signal on the screen, we have to locate the exact part where we hear this distortion, so we mark it.

Next, we go to the “Effects / Distortion” menu so that the customization window appears. In it we will have to specify the level of clipping to delimit the decibels of what is considered as distortion. With everything and with it we can leave the default parameters, but we must specify the type of distortion with which we are dealing.

Add echo to your audio recordings

The echo that sometimes appears in our sound projects is an effect that, depending on the type of work, can be an interesting addition to these works. Although at first adding this particular effect may seem a bit complex, it is not actually the case. Thus, Audacity again becomes an ideal solution, since it proposes a function to add this that provides a more professional touch.

To do this, we go back to the “Effect” menu, although in this case, after selecting the part of the track, we click on the “Eco” option. This leads to a new window in which we specify the delay time for the effect itself to be added, such as its depth . Say we have a preview button to check the changes in real time.

Normalize the volume of your audio tracks

When we talk about normalizing the volume of an audio file, we actually mean that everything we select sounds at the same level . This is something that we can carry out both for the complete track, a part of it, or for several. This is a recommended function if we are going to share that audio file with others, for example. And it is that these ups and downs are very annoying and do not look good.

To solve this bug, click again on the “Effects” menu, and then select the “Normalize” option. Here we can already establish the level of normalization, although it is advisable to leave the one that we find by default. Of course, before accepting the changes, we can see how the audio will be from the preview button.
