Analog audio signals are alternating current (AC) electrical voltages, meaning they constantly reverse polarity from positive to negative. The rate of this oscillation determines the frequency of the signal, which can vary from less than 20 times a second (20Hz) to more than 22,000 (22kHz), the range of human hearing. The amplitude of a signal's peaks determine its volume when amplified, and together these two variables can create complex signals capable of accurately replicating sounds.
In AC audio signals, however, this frequency is modulated to match the pitch of the sound being reproduced, just like sound waves alternate between high and low pressure. Though it's easiest to imagine a simple sine wave oscillating smoothly, most audio signals are far more complex, containing multiple frequencies and overtones.
But frequency is only half of the equation. The amplitude of the positive and negative peaks is variable as well, and this property determines the level or volume (when amplified) of the signal, measured in decibels. It's these two constantly changing values—frequency and amplitude—that allow analog systems to recreate complex sounds as electrical signals with astonishing accuracy, and to convert them back again so we can hear them through speakers and headphones.
Audio signals can originate in a number of ways: They can be electrically generated from the start such as in a synthesizer, they can be generated based on digital information by a digital audio converter, or (in many cases) they are converted from another type of input by a transducer. A transducer is any device that converts one form of energy to another. Different types of transducers are found in many musical devices.

◎Buy back program.⤵︎
If later you decide that you don’t need the cables or the items purchased we offer to buy them back from you. Since we put a lot of effort into every build and design we trust our quality and might buy them back and sell them on our official website for 2nd hand market, modify them or offer them as alternatives for lower-budget clients or repurpose them. If the items are kept in good shape and in working order we offer up to 80% of the purchased value excluding the shipping cost. Is almost like renting an item for a period of time. This might save you the hassle to resell the item for a lower value and save you time.
