Audio Effects-Noise Gate & Flange
Continuing the audio effects series, again, we all know of audio effects and what they generally are supposed to do. They are used to manipulate audio in ways that are not available with traditional playing and recording techniques. If youre like me, and enjoy dabbling in audio production, youre probably familiar with all the basic effects and maybe some other types.
Noise gate will be one of the topics of discussion today. Noise gate, what the heck is that? If that was your first reaction, youre not alone. Please dont worry; we will be demystifying this subject later on in the article. We will also be discussing flange, which is a more standard and widely used audio effect. So, in todays article we will be discussing both noise gate and flange effects, how they work and why they work the way they do.
Noise Gate
Basically, noise gate is a device or software logic that is used to manage the volume of an audio signal, in recording studios and in sound reinforcement. They are also used by musicians, in a portable form, to control amplification noise. At its most simple form it controls noise by only allowing sound to pass through it at a certain set threshold. Think of it as a literal gate; when the gate is open sound can pass, when the gate is closed no signal is allowed through.
More robust noise gate units have extra controls, I.E. attack, sustain, decay, release. This is so that you can further control the gating of your audio. Say youd like to have the gate applied in a hard fashion, you would set a short attack and a short release, so on and so forth. Noise gates are often used to isolate background noise from live recordings in order to eliminate them from the final copy.
Flange
Flange is related to the phasing effect produced by a, well, phaser effects unit. It is produced when two identical signals are mixed together, with one of the signals time-delayed by a small and gradually changing amount. The amount is usually equal to or less than 20 milliseconds. Peaks and notches are produced in the combined frequency spectrum, related in a linear harmonic series.
Part of the output signal is fed back in and resonates, intensifying the peaks and notches. This effect was originally generated with 3 three headed tape machines. Two of the tape machines would play the signal, obviously somewhat out of synch, and the third tape machine would record the output. The modern version of the effect is created using DSP (digital signal processing) technology.
This is the second part in my continuing series on audio effects. Today we discussed noise gate and flange, well be moving on some more advanced effects later on. I hope that this helped you all understand the basic functionality of these two effects, ultimately making your next foray into audio editing a bit less intimidating.

Endurox R4 Fruit Punch Review
I would highly recommend the Endurox R4 to all those who are into serious work outs. Trust me this is a highly efficient recovery drink and a lot better than the Gatorade. It comes in different flavors including Chocolate, Vanilla and Fruit Punch.
Before taking the Endurox R4 make sure that you seriously require this power packed energy drink because just like any other recovery drink this comes with good amount of calories and if that is not utilized, it gets deposited as fat and it is against the basic principle of exercise.
This not only replenishes the lost salt and electrolyte lost during the work out or strenuous activity, but also gives an instant rush of energy. I can really feel that and I always carry it with me when I go for long drives and trekking.
Endurox R4 enhances the endurance, physical stamina and mental alertness. When take after long distance cycling, driving and marathon, this greatly reduces the pain in the leg and muscular cramps. It facilitates to bring you back on track and the fatigue vanishes soon.
I find this too sweet and my pick is the Fruit Punch. It is palatable and there is nothing good to mention about its taste. It does not have any weird typical energy drink smell. To make it more appealing, I chop some fresh banana and throw the powder in blender along with ice.
This makes a refreshing drink and revitalizes the body. Endurox R4 Cards mixes readily in water and the consistency is also ok. But I add 15 oz of water to scoops of powder rather than 12 oz and this improves the consistency. When I am traveling, I have it mixed with package juice or just plain water.
Success of the Endurox R4 can be traced back to its unique composition that was formulated by an experienced exercise trainer who knew what exactly is required by the body after long exercise schedule.
This derives its name R4 from the fact that this patented composition contains 4 parts of glycemic carbohydrates to one part of whey protein. This ideal ratio or carb and protein along with antioxidants, electrolytes and vitamins facilitate to replenish the glycogen lost during exercise and muscle strength is also improved.
For best results this should be taken R4 Card immediately after work out. Usually I feel lost and go low after trekking, but with this there is no longer such issues and it gets absorbed immediately in the system to show results.
