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

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

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

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

Audio content inside (as we always provide them).

Cleanup audio online

As you might have expected, more and more online services offer automatic audio restoration as 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 didn’t put our 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?

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

Please use headphones to get the best results.

Original recording



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

After automatic noise removal



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

After a professional audio expert fixed it


No noise at all, and the 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, the noise's gone, and the voice is loud and full, natural with great low-end.

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


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

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


What do you think? Please share your thoughts below.

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 also cause it if they don't know what they are 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,

    We have several tapes that we need to get amplified and cleaned up. If we send over one can you look at one 30 second portion and see if it can be done?

    Hi Mark,

    Sorry for the belated reply. If you're still interested, please send us one of your files through the main page of this website.

    Tapes can be improved significantly for sure.

    Thank you,
