What is DUY MagicEQ?

MagicEQ is a mastering tool, based on a new equalization concept that can be resumed in 4 words: Statistically-Adaptative Automatic Equalization. Available for RTAS systems running OSX.

To use DUY MagicEQ, you should insert the plug-in, play your music and click on the LEARN button. This will begin a process of analising your music, which will result in an auto-equalization of your song. You can still modify many parameters after the EQ'ing has magically taken place.

With a previously unknown precision and processing complexity, DUY MagicEQ is a new high quality software plug-in for TDM OSX systems. It is not a standard EQ. To understand how it works, read the lines below, as well as the explanation on the "Technology" used. However, the best is for you to try the demo to find out the amazing power of DUY MagicEQ.

MagicEQ will not equalize in the same way any musical piece of audio. Or, in other words, depending on the music we're processing, the type of equalization calculated by MagicEQ will vary completely. This is one of the main features that makes DUY MagicEQ so different from classic EQs.

Once MagicEQ has run through the song and analysed it, the engineer will simply have to decide how he would like MagicEQ to finish the equalization of his mix, by tweaking a few buttons. MagicEQ will do the rest. Of course, MagicEQ will not make decisions in the name of the engineer, but it will certainly do the "dirty job" of having to move thousands of faders up and down.

MagicEQ lets the engineer's mind free from the usual troubles in traditional mixing and mastering, such as lack of precision and errors in the mixes, due to inconsistencies or monitoring and room non-linearities, acoustic resonances, certain equipment's undesired effects, differences in the sound levels, or simply due to human hearing fatigue.

If a mix is already very good, MagicEQ will make it sound even better. But if the mix has any deficiencies, MagicEQ will thin them out and will correct them automatically.

How does DUY MagicEQ work?

The main intention of DUY's MagicEQ is to make equalizing easier for the engineer throughout the mastering process. The simplicity of use is an outstanding feature.

In just a couple of minutes, your song can be wonderfully equalized!!! It's... MAGIC. If you still don't believe it, try out the Demo and check for yourself!!

Normally, an EQ is blindfolded when it gets to processing. It doesn't "listen" to what it's equalizing. A traditional EQ lowers or enhances the level of a certain frequency without knowing what signal it's processing, and obviously without knowing the final result.

We can use a normal equalizer to increase the level at 1.2 KHz with a certain bandwidth of a Q=6, for example. It will be the engineer's responsibility to know if that particular band will allow us to obtain, for example, more "punch". The engineer will also have to experimentally check if he obtained the desired result.

With DUY's technology, you can tell MagicEQ how you would like your music to sound, and the software will take care of all the rest. When you press the LEARN button, a detailed analysis of the sound to process will begin. The result is immediately passed onto the OFIR technology with zero latency (see the "Technologies" section for further information). These details are equal to thousands of equalization bands, which will start adapting themselves without the engineer having to do anything at all. In the meantime, you can visualize on the lower display if your bands are pushed up or down with precision as the musical analysis is in process. If you wanted to do this with standard methods, it would take hours or maybe days, and the result would never be comparable to the precision achieved with DUY MagicEQ.

Once the LEARN analysis is over we can polish the result, either by selecting any of the many provided responses, or by modifying them at our choice with the spectral band controls, the Spectral Atmospheres and the amount of effect.

MagicEQ can forecast the engineer's desires without him having to take part in the process, and with a unique precision. This can be done thanks to intermediate processes within the analysis.

The design of MagicEQ removes all complexity in the equalizing process, by reducing the procedure to moving a few knobs, making it very easy to use.

MagicEQ functions creating the FINAL response curve. The user is to determine what this curve should be like.

MagicEQ also allows to accentuate the result by bands or also by "colours" / "spectral atmospheres", by using one dial for each "colour". These "colours" can also be combined, to have an optimal result with an unprecedented control in known audio hardware and software devices.

Therefore, the way to use DUY MagicEQ can be summarized in the following way:

• 1 - While your music is playing, press the LEARN button to let MagicEQ listen to your music. This will usually take a minute or so.
• 2 - Once the music has been analysed, gradually increase the Amount knob in the output section of the plug-in, to start adding in effect to your original sound, until you're satisfied with the result.
• 3 - With steps 1 and 2, your music should already sound properly EQ'd. However, you can still perform further adjustments by tweaking any of the 4 very special "Spectral Atmospheres" knobs. These controls are called "Ouhm", "Boog", "Haxx" & "Sizz". Each one of them span a wide spectral region where there are many complex frequencies. These "colours" are the result of the complex and detailed statistical analysis of the "colours" or spectral atmospheres that can be found in the most successful music pieces, throughout the history of recorded music.
• 4 - You can now still adjust the sound with the help of 5 knobs that control 5 bands: Sub Low, Low, Mid, High & Ultra High. These controls correspond to contiguous frequential bands. If they are all set to zero, the response is theoretically flat.
• 5 - With the "Amount" control in the output section of the plug-in, you can still adjust the amount of EQ effect you want to add to your mix.

The technology behind DUY MagicEQ

Until today, it hasn't been commercialy profitable to create automatic mastering tools, because the cost of the technology was too high.

DUY has made this possible, thanks to the simultaneous use of 3 technologies, as a result of 4 years of intense investigation:

1) OFIR (Optimal Frequency Impulse Renderer) Technology

DUY's new OFIR (Optimal Frequency Impulse Renderer) technology, to render audio with zero-latency, allows the processing of amazingly complex equalizations. The great advantage of the OFIR technology is its great resolution and definition, preserving a virtually zero delay.

2) Adaptative Spectral Matching (ASM) technology

This technology statistically analyses the input signal in realtime. By combining this analysis with the OFIR technology, we can achieve an adaptative spectral match. Therefore, we can make the overall mix of a certain piece of musical audio sound like that of another one.

But these two technologies would be close to useless if we didn't know what mix we want to use as references for our mixes. This is the target of our third amazing technology:

3) Historical Audio Statistics (HAS) Technology

MagicEQ includes the HAS system (Historical Audio Statistics). This technology, developed by DUY, has allowed us to make a complete statistical analysis of the spectral contents of the best and most successful productions in the history of recorded Music. The result of this study has allowed us to define objectively which are the "colours" or Spectral Atmospheres that can be found in all the successful music pieces of a certain style, throughout history. It has also allowed us to analyse the way how mixes have evolved, and even better: we can analyse where this evolution is leading to!

These statistical analysis are implemented within MagicEQ in the way of "colours" or "spectral atmospheres" which we have specifically implemented in the control knobs tagged as "Ouhm", "Boog", "Haxx" and "Sizz". We have named these "Spectral Atmospheres" with totally new onomatopoeia, because these controls don't correspond to any similar existing "colour". They are totally new colours, and therefore they have totally new names.

Regarding the SubL, Low, Mid, High & UltraHi controls, these don't correspond to any Spectral Atmosphere, but to standard frequential bands. The main difference between the frequential bands and the spectral atmospheres is that the bands have a minimum colouring, because they have no resonant peaks. The other difference is that the bands are complementary between them: if you set all their controls to zero, you'll have as a result a theoretic flat response, so each one of these bands overlaps with the 2 contiguous bands, with the exception of the SubL and UltraHi bands, which have the limits of the audible spectrum on one of their sides.

The ASM and HAS technologies turn DUY MagicEQ into a totally different audio processor in comparison to any other in the market. At the same time, the spectral bands and colours produced by MagicEQ can't be found in any other existing audio processing device.

The result of the 3 described technologies allows us to implement a totally exclusive system.
