Automatic vs professional (manual) audio clean up - Samples included

Is it worth it to use automatic background noise removal services?

Or you need to hire a professional audio restoration specialist instead in order to get the best possible quality?

Well, let's see three audio samples and judge yourself.

Audio content inside (as we always provide them).

Cleanup audio online

As you might have expected, more and more online services are offering automatic audio restoration as a baiting in addition to their other (paid) services. Their main profile is paid video editing usually. We have tested whether they are worth using such services.


It wouldn’t be fair if we don’t put our own work next to it, so let’s see and hear the three samples.

What do you think which one will be the best, most pleasant for the human ear?

The automatic one or the one produced by our online audio clean up service?

To achieve proper result please use headphones

Original recording



With a lot of background noise, voice is weak as well

After automatic noise removal



There's a huge left-over noise, voice is louder, but still weak

After a professional audio expert fixed it


No noise at all, voice sounds professional


As you can hear the automatic solution couldn't really handle the task, so you hear a lot of left-over noise, the voice is still weak, but a bit louder though.


After professional audio clean up the result is clean, noise's gone, the voice is loud and full, natural with great low-end.

As you probably wants to get it after background noise removal.


All in all if you don't need professional sounding audio material it might worth to use automatic services.

For professional work hire a professional. Huge amount of audio restoration specialists out there online, it's not more complicated to reach out them.

Update 1.)


We daily receive tons of audios that "AI" failed to handle. If you have this type of work, please send us the original, unedited/unprocessed file(s), because audio services based on Artificial Intelligence can cause irreversible damage to the sound. People can cause it as well, if they don't know what they're doing. Thank you.

    Hi Richard,

    I have some mp3 files, taken from a video, that I need to fix.

    Probably due to the wifi microphone, in some places the audio appears louder (and with a strange background echo, as appear immediately, at the beginning), and in some places it appears lower (normal).

    Is it possible to fix them? About 5 minutes each one.

    If so (which I hope), I'll have to arrange 6 audio files (roughly the same length as the attached audio). How much does it cost?

    Thank you.

    Hi Andrea,

    If you read this, I don't have any contact to you, so let me suggest to send us one of your (original!) files for a free review in order to see if it can be fixed.

    Thank you,
