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).
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
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.

Giant things are happening in the world,
one of them is it seems like bad audio quality is undesirable finally.
Let us introduce you the PONO PLAYER high-resolution portable digital music player.
As an audio engineer I highly welcome this new audio pocket player.
The PONO Player able to play high-definition audio up to 192 kHz/24bit resolution, so now you can digitize your favorite vinyls and listen to them on public transport, or in your car.
I hope finally it can beat the iPod and MP3, so I don't have to fight against them anymore.
The Pono Player plays MP3 too, but trust me, you don't want to listen to MP3's anymore :)
I can't describe you how happy I am, and how I hate these compressed file formats.
Only little minus that I dont think this little player is ergonomic due to its triangular design.
It would not be comfortable when you sit down with a PONO Player in your hip-pocket.
Good news for professionals that they can use the 2 3.5mm jack outputs in balanced mode, so only thing they need is two small stereo jack-XLR adapter or cable.
|FLAC, ALAC, WAV, AIFF, AAC, MP3|
|Music resolution||Lossless playback at up to 192kHz / 24bit|
|Storage||128GB total - 64GB flash memory plus SanDisk 64GB microSD card included|
|Expansion slot||Supports microSD cards of up to 64GB|
ESS ES9018M DAC
Large 2900mAH Li-Ion rechargeable for up to 8 hours of playback time
AC universal adapter (100-240 VAC)
2.5 inch color touchscreen
Two 3.5mm (1/8 inch) jacks, supports four listening modes
130 grams (4.6 ounces
13x5x2.5 cm (5x2x1 inches)
Anyway, the two 1/8 inch (3.5 mm) audio output jacks offer you four modes of operation:
listening mode via headphones or earbuds,
2) home stereo or in-car listening mode with fixed volume output,
3) PonoShare mode with two pairs of headphones/earbuds,
4) balanced mode provides ultra-performance for advanced users, separating left and right channel outputs across the two jacks. Great for use with high-impedance headphones, high-end home stereo systems, or professional equipment using balanced XLR input connectors.
Audio files can be loaded onto the Pono Player using the Pono Music Center desktop application (soon to be released on Windows and MacOS). The PonoPlayer can also be sideloaded as a USB storage device (Windows, MacOS, Linux).
Hurry up to pre-order! (ammm, yeah it's pricey)
There you are the latest episode of Beyond Bitcoin podcast. Arthur Falls is a very kind person who really a pleasure to work with.
Please enjoy his show as we did while it was under process.
Let's see 17 tips and tricks before you start to record your podcast. Please take my advice, everything on this list is very important to get a good sound quality podcast at last, that is ready for podcast mastering. Please, feel free to ask in the comment section below.
If you already have a lot of MP3's, don't save them back in MP3 again after the cutting/ trimming/ mixing processes (avoid double compress), use lossless file formats instead (as I marked above: .wav, .aiff, .flac)
Record the mics to separate channels in your recording software, it will help in mixing it separately
If you spend money on quality audio equipments, like amps, speakers, headphones,
why would you cut corners on interconnect cables? Here's a test/ review of two audio cables, a common audio cable and the Mogami neglex 2549. Mogami is much used in audio studios, so it might be good for us as well to listen to music.
No, I am not sponsored by Mogami.
Usually in tests like this, a professional tells you the 'truth', and you believe him, because he is a professional. But now you can see and hear the difference, so you can believe your own eyes and ears.
As you can see on the pictures below, the Mogami cable is more senseless to low frequency hum than the common one. The hum itself and its harmonics, in this case 150Hz and 250Hz, are due to the frequency of electrical networks, which is 50Hz in Europe.
Common cable noise profile on phono usage
Mogami neglex 2549 noise profile on phono usage
OK now, let's see closely how these cables sound. The vinyl was the Daft Punk - Random access memories album, because it's a
masterpiece of sound engineering.
Sorry I can't upload the whole files, only samples because of the copyrights.
The original sample rate was 192kHz/32 bit, but I couldn't upload to sound sharing sites,
than resampled to 44,1kHz/16bit (normal CD quality).
Common cable sounds
Mogami neglex 2549 sounds
So here is the evidence, the Mogami sounds more detailed, precise, clean (try to concentrate to reverbs and snares), bright and its frequency response is as flatten as an ironed shirt, maybe it's worth the (not so much) money.
Don't worry if you didn't hear the difference, maybe your ears are tired now, or it will be come later in your life,
or you are in need of really good headphones or speakers.
Update: thanks to the SoundCloud audio compression... maybe I will change player widget...
Update no.2.: I've changed the audio player to Hearthis.at's, that is more flexible and cheaper than SoundCloud. It can play .wav, .aiff, etc. You should try.

Here is a sample how we remove reverb from audio on video.
Our friend, Alban asked us, if it's possible, apply some de-reverberation on his video, because he recorded it in a very big, empty hall, and it sounds very "roomy".
Please note that the video was taken with a mobile phone, so it's not perfect, but perfectly suitable for presentation.
The sound of the video have not been mixed yet, what you hear is caused by the de-reverberation only. Sounds much-much better, isn't it?
