![]() Bandpass: Bandpass filters pass a specified range of frequencies and attenuate any others outside this range.Įach serves a different purpose when applied.High-pass: High-pass filters do the opposite of low-pass filters by letting through high frequencies above a specified point and attenuating any frequencies below said point.Low-pass: Low-pass filters pass through all frequencies below a specified point and attenuate any frequencies above it.There are various types of filters, including: This trims down the higher and lower frequencies in the whole frequency spectrum to only those you want to hear. FiltersĪside from boosting or cutting the frequencies one by one, you can also make use of ‘filters’.įilters are used to boost, pass or attenuate certain range of frequencies. Spotify, for example, has a five-band equalizer that controls 60 Hz to 16 kHz. Raising it will make all sounds in that frequency louder, while lowering it will do the opposite. When you look at an equalizer, you’ll see a slider that allows you to adjust the decibels for each frequency. When it comes to volume level, or loudness, this is measured in decibels (dB). The same applies in reverse lower frequencies equals lower pitch. Faster cycles per second result in a higher frequency, which then results in a higher pitch. These dictate the pitch (or how high or low the notes are). High and low frequenciesįrequencies are measured in Hertz (Hz), referring to the number of soundwaves per second. ![]() A frequency is determined by the number of complete cycles (vibrations) that occur in one second, creating a waveform more commonly called ‘soundwave’. When those vibrations reach our ear, it turns into what we hear as sound. FrequencyĪll sounds are the result of vibrations moving through the air. Let’s break down the audio terminology that’s commonly associated with equalizers, so you have a better grasp of what you’re changing. Oftentimes, you’ll see technical terms that you’re unfamiliar with. The Basics: Understanding Common EQ TermsĮqualizers, by default, can be quite intimidating. For instance, the quality of your headphones and the type of file compression used can also affect the end result. But, you must consider other factors that can impact your audio quality. That’s why a lot of people use equalizers to tone them down a bit.Īn EQ can make considerable improvements to your audio. For example, listening to high frequencies for long periods can easily trigger ear fatigue. By attenuating the frequency, you will hear that sound less. This will isolate that frequency more, making vocals louder. You can boost the frequency at which vocals are heard. It truly gives you the option to personalize your music according to your taste.įor instance, let’s say you want to hear the vocals over anything else in the song. You can adjust the frequencies you hear to focus on different elements of the song using an equalizer. The music you listen to may sound good, but it can always sound better when tuned with an equalizer. This is because it gives you wide control over how your audio sounds like. However, an EQ can make arguably better changes. ![]() There are other ways to improve your audio, like boosting bass from within your Windows 10 computer. This is no surprise, as it gives each person the ability to personalize their listening experience to suit them. You can even find them in your favorite music streaming services, like Spotify and Amazon Music, which include built-in equalizers. Today, you can find digital equalizers in a myriad of devices, like smartphones, speakers, and soundbars.

To account for this, an EQ gives you the power to tailor the music to your liking by choosing which frequencies you want to boost, and which you want to attenuate.Įarly equalizers used to be primarily hardware-based, making use of physical dials to manipulate the audio you hear. The problem here is that people don’t have the same tastes in music, and some may be disappointed by what others find superb. ![]() An equalizer, or EQ, is used to find your preferred balance between these frequencies in your music based on the environment, the listening method, and your personal preference.Īs mentioned, music that’s produced for a general audience is designed to sound decent in any environment, from any device. This frequency is then converted into sound when it reaches our ear. Your music has a wide range of different sounds, each belonging to a certain frequency.
