When DJ’s Redline.Īll songs are not mastered at the same level. This way the mixer has multiple levels of control to adjust audio input and output and avoid clipping. Additionally, there is also a master gain which controls the total output of the mixer. In a mixer, apart from channel fader controlling the levels of input into each channel, each channel has Hi’s Mid’s and Lo end level controls apart from a channel gain, which controls the overall loudness of the audio output of the channel. It is never good to overdrive the inbuilt pickups or amps in a mixer, especially newer digital ones as this would result in hard clipping. Redlining adds noise & distortion caused due to clipping. Increase the output of the mixer to a point causing the indicators to move out of the green and amber zone, into the red. This intentional overdrive in the guitar amplifier in order to get the desired sound is a perfect example of audio clipping used in a good way. Distortion on a guitarĭistortion on an Electric guitar is caused by overdriving the inbuilt amplifier to add harmonics and give a distorted effect. The Loudness war peaked in 2005 and since then normalisation of music and comfortable loudness has been pushed especially through online music distribution platforms. This results in overdriving audio equipment to result in forced clipping in extreme cases. Referred to as the loudness war where through the ages, music has been getting louder and louder. Since the advent of CD’s the recording industry has been increasing the master levels of audio using clipping & compression to make the average loudness of audio even louder. While recording, clipping is used as an effective way to increase the loudness of Audio. Over-driving one’s equipment is never a good idea, and will definitely eat into the life of your equipment, but do it correctly and it will give you the desired outcome that can be considered good for your audio listening experience. If it sounds bad then of course it is, but if used in the right way it can also sound good. Common occurrences of Audio ClippingĪll Clipping is not bad. It is less damaging to high-frequency drivers. It gives a smoother, better sound for easier listening. Here you see the Edges of the clipped waveform rounded off. Now if one is to start to overdrive the signal or in layman’s terms increase the amplification to a point the equipment can no longer handle the output, then the indicators on a mixer would start to touch red and that is when clipping occurs.Īlso referred to as analogue clipping as it occurs mainly in older analogue gear, where enough headroom allows for smoother sound with less distortion. Here the signal is undisturbed and indicators on the metering units of the audio equipment such as a mixer would be in the green or amber zone. See the sine wave this is what we want for our sound output, a smooth and clean flow. The height of each wave from 0db defining the Amplitude.Īn angular measurement of the time difference between two similar waveforms (expressed in degrees). It is the pressure of sound, measured in Decibels (dB). ![]() Lower the frequency larger the wavelength. Note: Frequency and wavelength are inversely proportional. The rate of repetition of a wave, measured in cycles per second. The Sine wave has 3 main characteristics: Frequency: ![]() The Graphical representation below will help you visually understand the Sine wave form. Therefore, represented as a Sine wave in 2 dimensions via the graph taking into consideration distance, time and intensity. Sound does not actually move in the form of a wave, it spreads in all directions evenly if not obstructed, as an oscillation of air pressure and normally looses intensity the further it moves away from the source. ![]() In essence, it describes the smooth periodic oscillation of constant amplitude. It is the way we represent audio as a mathematical graph. Considered as the building blocks of sound, Sine wave is the purest form that represents sound.
