MP3 artifact removal

No matter what compression you use there will be artifacts left behind.
This being said : I was once told that the Mp3 was the digital version of the cassette tape .
Based on this I set out to create a filter to help reduce these artifacts .
Meaning this swirling metallic flanging awful sound .

Using a parametric EQ I set some filters to create a comb
These freq. as follows;
10830 HZ
7830 HZ
4830 HZ
With a reduction of about 14 to 19 db and narrow widths this greatly reduced the artifacts.
It seems using a 3Hz harmonic rule works the best.
By adjusting the depth and width of this comb filter I can clean up almost every file I have.
I purchased a few years back the Accon studio rebirth harmonic plugin . This VST is neat in that I am able to draw back in the cuts I made
And slope off the top freq. to now about 18000 HZ on average depending on the file . Most of the time I reduce it to about 12000HZ remember the cassette thingy ……………………………….
Using a host I am able to reprint using a DAC at 192/32 thru a Analog EQ back to my ADAC .
And presto I have a good Analog file recorded in 192/32 digital format .
I can reduce this to 44/16 or MP3 320/ 41k
Both sound much better than the original .
And yes very much analog ……………………………………………………………………
So adding these plugins to your DAW would be a well investment .
A de- hisser can be added as well as a limiter for you in the box type of person .
It is possible to add a Vst rapper and create a preset for this filter it is kind of universal in its affect but for you in the box persons or just someone who does not have a DAC or ADAC this is a good alternative .
Now you can store this in you DAW and also use it for play back when you just want to listen . Even streaming if you set your rig up to do so.
Now this is just to darn good to pass up .

Thanks for the posting.

The video people came up with a similar “desperation method” for rescuing a track that was really too far gone even for jazz.

Digital does have its fuzzy edges. 44100 Music CD sampling rate isn’t accurate past about 17KHz, but through noise, interpolation, inaccuracies and limits on human hearing, it appears to work reasonably well out to 20KHz.

So I wonder if accuracy is the point if you can produce a pleasant sounding product, particularly if you’re doing it with left-for-dead work.


Please stop saying that, it is not true. It may have been true 30 years ago, but sync filters have left that limitation way back in history. With Audacity it is easy to prove that in the digital domain, 44.1 kHz sample rate is good to better than 20 kHz.
