Let’s say you’re starting a podcast, or you’ve recorded an interview, or yourself speaking in front of the camera… And when you review the content, you realize that the audio is not as good as you thought. To obtain slightly more professional results (once you have made your recording) you can use programs that do is remove background noise from your audios and so the voice sounds much clearer.
Obviously, everything will depend on the original quality of the recording, but in cases where you hear noise in the background (such as in a cafe or on the street), echo or other interference such as the typical electronic beeping, these solutions may help. that we present below will be most useful to you.
Tricks to eliminate background noise from your audios
With artificial intelligence
Recently, Adobe has launched its new system (inherited from Project Shasta) that, in short, uses its neural system to clean the audio that we upload to it. All this for free.
We simply have to drag our audio clip in MP3 or WAV format (if you have it in another format or in a video, you can use the free program to convert or extract it), as long as it does not exceed 1 hour in length and/or 1GB of storage, and your AI will start doing the magic. At the time of writing these lines, the service is in the testing phase and has no usage limit.
Below this line you can hear an example.
Original audio:
Processed by Adobe Audition:
The only drawback is that this artificial intelligence It is trained with audios in English, so in moments where some unfinished or grumbling voices are heard, the AI can “correct” the message by adding a voice generated in English. But as long as the lead vocal is heard loud, the cleanup of background noise is more than adequate.
Of course, another detail to keep in mind is that this portal will return the results in mono, even if the original file is in stereo.
Separate voice and music tracks in songs with AI
Another resource that is becoming popular lately is artificial intelligence capable of separating the vocal track of a song simply by providing it with an .mp3, .wav or similar file.
So, if what you want is separate the tracks of a song to get the instrumental and vocals Regardless, you can use it for free while it’s in beta. In this case it will only return the instrumental track and the vocal track isolated, instead of the different instruments separated in their respective take, as services such as (one of the best in this field) do, although this platform does not allow you to download the results. In its free model, only reproduce them on its website.
This last mention also has an option to eliminate background noise from your audios, and even allows you to directly upload a video file and it itself is responsible for analyzing only the audio.
