We deal with audio restoration professionally

It's interesting to note that more and more online services are offering automatic audio restoration as an add-on to their paid video editing services. It's advertised as free, but in the end, it always turns out that there are additional costs involved.

We tested one of them, and in this brief content, we'll present the test results. It wouldn’t be fair if we didn’t compare our work to theirs, so let’s listen to the three samples.

Which one do you think sounds best and most pleasant to the human ear?

Is the automatic one or the one produced by our online audio cleanup service?

Please, grab your headphones for the optimal experience:

Conclusion

After listening, it's clear that the automatic solution couldn’t handle the task. There is still a lot of leftover noise, and the voice is still weak, albeit slightly louder.

After professional audio cleanup, the result is clean, with the noise gone and the voice sounding natural and full, with great low-end.

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

Ultimately, if you don’t need professional-sounding audio material, it might be worth using automatic services. However, for professional work, it's best to hire a professional audio restoration specialist. There are many specialists available online, so it’s not difficult to find one.

What do you think? Please share your thoughts below.

Update 1.)

Just a quick note:  We receive a lot of audio files every day that AI isn't able to handle. If you have this type of work, please send us the original, unedited and unprocessed file(s) because using audio services based on Artificial Intelligence can potentially cause irreversible damage to the sound. This can also happen if people don’t fully understand what they are doing with the files. It's not their fault; it's due to the complex nature of sound restoration. Thank you!

Anyway, the two 1/8 inch (3.5 mm) audio output jacks offer you four modes of operation:

1) personal 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)

1. If it's possible, record everything by using professional microphones (avoid cheap and built-in mics)
2. Use popfilters on mics (it costs $10, the cheapest is still better than nothing)
3. Stay away from walls and corners (if your room has acoustic treatments on walls, you can sit closer to them).
4. Turn down the volume of your speakers to zero(!) while recording, and use headphones instead (including your guests)
5. Forget MP3(!), if you have space on your hard drive, record in WAV (on Windows) or AIFF (if you are on Mac)
6. Set the sample rate to 44kHz/16bit or if your soundcard is good enough, choose the 44kHz/24bit depth option, minimum
7. If you don't have space on your hard drive, choose the FLAC format to compress your audio files or use the mono recording option (the human voice is a mono source anyway)

8. If you already have a lot of MP3 files, don't save them back in MP3 again after the cutting/ trimming/ mixing processes (so avoid double compress), use lossless file formats instead (as it's marked above: WAV, AIFF, FLAC)

9. Use quality microphone cables, such as Mogami's Quad cable or Mogami Neglex 2549. If you have a USB mic, nothing to do, use the USB cable bravely
10. Take away the power supplies from the audio cables (otherwise, it generates a hum to the audio)
11. Keep your microphones away from your monitor display (otherwise, it can generate different types of noises in the audio)
12. Don't use external hard drives to record to it directly (only if it has a USB3 connection) it may causes glitches in your recordings

13. Record the mics to separate channels in your recording software (DAW), it will help in mixing it separately

14. Turn off the built-in sounds of softwares, such as Skype (etc.), during the recording
15. Turn off the system sounds of Windows (or macOS)
16. Turn off screensavers
17. Take out or switch off your mobile phones

Happy podcasting!

If you spend money on quality audio equipments, like amps, speakers, and 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.

Noise

As you can see in 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.

Sound quality

Okay, now, let's hear 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 it to sound-sharing sites,

than resampled to 44,1kHz/16bit (normal CD quality).

So here is the evidence, the Mogami sounds more detailed, precise, clean (try to concentrate on reverbs and snares), bright and its frequency response is as flattened 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 coming later in your life,

or you are in need of really good headphones or speakers.

Update no.1.

Thanks to the SoundCloud audio compression... maybe I will change the player widget...

Update no.2.

I've changed the audio player to Hearthis.at's, which is more flexible and cheaper than SoundCloud. It can play .wav, .aiff, etc. You should try.

Update no.3. 

The test setup  was the following:
Ortofon MC15 Super II -> Throrens TD126 mkIII -> cable A or B -> Creek OBH 15 mk2 -> cable A or B -> RME Fireface UC

Where "cable A" was Mogami 2549, "cable B" unknown because the inscription was worn down.

Used connections:

Neutrik gold plated RCA and Jack 6.3mm
