Whether you‘re an audiophile or casual listener, a good equalizer app can take your mobile music experience to new heights. Equalizers enable precise audio tuning by providing granular control over different frequency ranges. This allows you to customize the sound signature to both compensate for headphone flaws and match your preferences.
In this comprehensive guide, we will cover everything you need to know about equalizers along with the top apps available for Android and iOS devices in 2023.
What is an Audio Equalizer?
An equalizer adjusts the volume levels across different frequencies to shape the overall sound. The app provides multiple filters or bands spanning the audible range of sound frequencies from bass to treble.
- Bass frequencies are below 250 Hz responsible for low, thumping sounds
- Mid frequencies from 250 Hz to 2 kHz create vocals and percussion
- Treble above 2 kHz delivers the sparkle and liveliness
By turning these bands up or down, you effectively contour the music to alter its tonal balance. Boosting certain ranges can uncover details, while attenuating others reduces muddiness or harshness.
Equalizers are particularly useful for compensating for the frequency response irregularities inherent in all headphones and earphones. This helps mitigate resonances that color the sound and improve overall fidelity.
Graphic vs. Parametric Equalizers
There are two main types of equalizers used in apps:
Graphic Equalizers: These provide a fixed number of bands, usually 5 to 10, distributed evenly across the frequency spectrum from 20 Hz to 20 kHz. Each slider controls a particular frequency region. Graphic EQs give a general tonal shaping capability.
Parametric Equalizers: Parametric equalizers are more advanced, offering independent control of center frequency, bandwidth, and gain for multiple user-configurable bands. This facilitates precision tuning and restoration of pinpointed sound issues.
While parametric equalizers allow bespoke sound customization, graphic equalizers tend to be easier to use for basic musical enhancement.
Key Features of a Great Equalizer App
When selecting an equalizer for your device, here are some top capabilities to look for:
- Number of bands – 5-band at minimum, 10+ better
- Quality frequency range – expands beyond human hearing
- Multiple presets – covers genres and music types
- Stereo independence – separate L/R adjustment
- Channel balancing – center bias control
- Zero latency – processes audio in real-time
- External DAC support – works with USB gear
- Parametric EQ option – ultimate precision
Other handy features include per-app profiles, widgets, live analyze, importing settings. We weighed all these elements when picking the top equalizer apps.
