沒想到Cardas也與iphone接軌，推出這個「Clarify」app，下載只要0.99美元，用途是消除單體、分音器、或耳機的殘餘磁性，有就是消磁啦。網路上有人已經試用過，據說效果就像是把玻璃窗擦乾淨一樣，音質的確更為清晰。怎麼使用呢？只要把iphone接上耳機或音響系統，啟動Clarify後，會產生一的極低到極高的連續音，聲音跑完就OK了。其實Ayre之前曾推出過的「Irrational but Efficacious」CD就有同樣效果（別忘了Cardas與Ayre交情匪淺），只不過現在Cardas將這個功能做成app，價錢更便宜，讓更多人可以受惠。
當然許多音響迷會質疑，光是run一遍這個軟體就可以消磁嗎？George Cardas為此還特地親自解釋，原文如下。總之，價錢不貴，下載來試試看也無妨。

Below is George Cardas's explanation of the Cardas Clarifier App:
"Seriously guys this is super simple.
Degaussing is used on everything from tape heads to ships to reduce or eliminate residual magnetism. Some ships have coils built into them for the purpose.
The gaussing of ferric materials is ubiquitous and has been know for thousands of years. (think compass's)
Here is some history:
In the old days, analogue tape recorders LOST RESOLUTION as their recording heads accumulated residual magnetism, recording engineers used small portable coils or wands to degauss the tape heads. The wands used a constant sine signal in the coil, the coil was placed on the tape head and slowly drawn away manually to attenuate the signal progressively.
Fluxbuster's used a sine signal in the coil of a phono cartridge that was slowly tapered off to degauss the cartridge pole piece.
Circa 1987 Cardas Sweeper LP , it was released . The record generates a signal in the coil that was slowly attenuated in amplitude and period(frequency) , with this LP you could now run the sweep thru your entire system thus degaussing your speakers. This record is still in production. (Circulation 30k+)
The Ayre "Irrational but Efficacious" CD is a very popular CD that incorporates our original sweep.. These sweepers soon made all other methods obsolete for stereo system degaussing.
This is an ancient technology but the real underlying pearl of wisdom is not what we are doing or how we are doing it BUT WHY!!!
There is an intrinsic problem with dynamic loudspeakers and this problem becomes larger and more profound as the speakers becomes smaller for reasons that I will not go into her, it suffices to say that there are tens if not hundreds of thousands of people that are regularly degauss much large speakers in their home systems with very good and repeatable results.
The original method of degaussing was to install electromagnetic coils into or around the ships, it was known simply as coiling.
In our system the coil is the one in the speaker itself -- a real advantage of the sweeper method is that the signal (and thus associated magnetic field) can be attenuated in both amplitude and time interval (frequency) !!
Degauser's work by alternating reversing the magnetic field in the semi-saturated metal pieces in the speakers magnetic circuit in smaller and smaller increments, moving them towards the magnetic zero point. -- In the Clarifier App I use a logarithmic attenuation of amplitude and time period (Frequency) this is noticeably superior to simply attenuating a sine because of material hysteresis.
anyway ...
This this a great app it will make a little of difference that some of you will appreciate and a few of you will find ALL OF THIS very enlightening HEY it cost a *ing dollar!! give it a try. You will learn something and have some fun, try it on your car stereo if you have a input port do you wife's IEM's she will love you.

OK here is an interesting disclaimer -- the real problem here is in the design of the drivers themselves. Like in conductors/cables fixing the geometry itself is the real step forward not band-aids like this -this app is a partial and temporary solution that has to be repeated from time to time. -one of my current projects is the design and production of a driver design that has no saturable material in the magnetic circuit.. preliminary results are very interesting. It's why you are all waiting for my IEM's ;) LOL
Peace and Harmony
