Especially at risk are the tweeters given the high-frequency harmonics often present in a clipped signal. As your speakers don't get the power they need from the amplifier, they end up demanding more power than can be delivered. If you have high-performing loudspeakers and a lower powered amplifier, your system will be prone to clipping. If the amplifier and speakers are mismatched, too much power could be pulled, resulting in potential damage to your speakers or amp and distortion to the signal. The lower the impedance, the less resistance your speakers will offer, meaning that they will pull more power from the amplifier. The impedance is measured in ohms, indicating the amount of resistance offered by your speakers to electric current. One of the biggest causes of clipping in home hifi setups is due to mismatched impedance between the speakers and amplifier. While we may want that sound when it is made on purpose on a guitar track, if the whole piece is affected, it will sound awful. Fuzz can often sound like a load of bees in a bottle. Distortion happens when the audio begins to break up and quality is lost. Overdrive is often unnoticeable when it is at lower levels on the signal. We have three types of clipping, which guitarists will be all too familiar with: overdrive, distortion and fuzz. This flat plateau at the top or bottom of the wave will be an unnatural and jarring event that will sound horrible. If that sound wave gets too big, instead of having a nice smooth curve at the base and apex, we end up with a straight line connecting the uppermost and lowermost points of the curve. If you think back to your high school science classes, you may remember that a pure tone is represented by a sine wave, which is a smooth curve going up and down based on the frequency (pitch) and amplitude (volume) of the sound source. We call this phenomenon clipping because that is what the waveform looks like. Purple Haze has enough overdrive on the guitars without any more being added on your end. When watching a movie or listening to a piece of music, on the other hand, we want to listen to the sound as it was intended to be heard. Where would Jimi Hendrix have been, for example, without his Marshall Amplifiers and Roger Mayer effects, which created his signature overdriven guitar sound? In some instances, this clipping caused by overdrive is desirable or even deliberate. This overdriven signal makes the amplifier try to produce output voltages that are beyond its capability, which is what causes the clipped signal. When an amplifier is pushed beyond its maximum working limit, it ends up going into overdrive. In simple terms, clipping is caused when the signal is too loud for either your amplifiers or your speakers. Let's take a look at what it is, how it is caused, and how best to fix it. We have all at one point or another experienced audio clipping, even if you aren't really sure what it may be.
