Is equalizer app free?

An equalizer app is a type of software that allows users to adjust the frequency levels of audio output. Equalizers enable customization of the sound profile, letting users enhance certain frequency ranges while reducing others. This allows for audio to be tailored to personal preferences or the characteristics of headphones/speakers.

There are both free and paid equalizer apps available. Free options provide basic equalization capabilities and presets, while paid versions offer more advanced features like additional bands and greater precision. A key question around equalizers is whether the free apps provide sufficient audio adjustment or if the paid versions are necessary for quality customization.

What is an Equalizer App?

An equalizer app is a software program that allows users to adjust the frequency levels of audio playback. The app provides control over different frequency bands – bass, midrange, and treble – so users can customize the sound output to their preferences. Equalizers are commonly used to enhance the bass in songs, boost the clarity of vocals, or adjust the overall tonal balance.

The main purpose of an equalizer is to change the amplitude or volume of different frequency ranges. For example, increasing the lower frequencies will amplify the bass, while reducing the high frequencies will diminish the treble. This allows users to tune the sound signature and achieve the perfect listening experience for their headphones, speakers, or other playback devices. Equalizer apps provide easy access to these powerful audio controls.

Common uses for equalizers include enhancing the sound quality on headphones, boosting bass in music listening, optimizing audio for different genres, and compensating for limitations in speakers or room acoustics. With the right equalizer settings, users can make their audio sound more lively, balanced, or customized to their taste.

Free vs Paid Options

When it comes to equalizer apps, you have options. There are quality free equalizers available, but there are also more advanced paid options with additional features.

Many free equalizer apps offer basic functionality like multiple presets, several frequency bands to adjust, volume boosting, and compatibility with multiple music apps. For example, Equalizer & Bass Booster by Smart Android Apps and Equalizer & Bass Booster by PerfectAlly provide up to 5-6 presets and 5-6 frequency bands to customize your sound profile (Android Authority).

Paid options like Poweramp, Wavelet, and Boom: Bass Booster & Equalizer offer more advanced customization. These have features like 10-32 frequency bands, stereo expansion, fine tuning, custom presets, and integration with system audio (SoundGuys). The additional features allow more precise audio adjustment.

Ultimately both free and paid equalizers can enhance your listening experience. Free options provide basic functionality while paid unlocks more advanced audio customization. Consider your needs and budget to decide which type of equalizer app is best for you.

Top Free Equalizers

Some of the most popular and highly rated free equalizer apps include:

Wavelet – Wavelet is an open-source equalizer app for Android that includes a graphic equalizer, bass boost, normalizer, and spatial audio. It supports system-wide audio adjustments and custom presets.

Boom – Boom is another Android app with a customizable equalizer, volume booster, virtualizer effects, and presets for various music genres. The free version includes basic EQ features.

Viper4Android – Viper4Android is an advanced equalizer for rooted Androids. It provides enhanced audio quality and various effects like a tube amplifier emulator. The basic version is free.

These are just a few of the top options for free equalizer apps. Most offer customizable frequency sliders to shape sound to your liking. However, free versions tend to lack certain advanced features.

Capabilities of Free Apps

Free equalizer apps provide users with basic equalization capabilities to customize the sound from their device’s speakers or headphones. According to the Equalizer & Bass Booster app on Google Play [1], free apps allow you to adjust frequency levels to boost bass, treble, and mid tones. They also come with common preset equalization settings like Rock, Pop, Jazz, and Classical to quickly optimize the sound profile. Additional basic effects include surround sound, 3D stereo expanding, and reverb to add spatial audio effects.

The key capabilities of most free equalizer apps include:

  • Customizable frequency level sliders for bass, midrange, and treble
  • Preset equalization modes like Rock, Pop, Jazz, etc.
  • Basic audio effects like surround sound and reverb
  • User-defined presets to save customized equalization settings
  • 10-20 band equalizer with frequency range up to 16-20 KHz

Free equalizer apps offer enough features for basic personalization of audio output to satisfy casual listeners. The limited capabilities may be sufficient for users who want quick access to a few common equalization presets and don’t require fine-grained audio customization.

Limitations of Free Apps

While free equalizer apps provide some basic functionality, they also come with several limitations compared to paid options. Some key limitations of free equalizer apps include:

No systemwide audio changes – Most free equalizers only affect the audio within their own app, and don’t allow you to change the systemwide audio output. This means you have to keep the equalizer app open at all times to get the benefits.

Limited preset options – Many free equalizers provide only a handful of preset options to choose from, while paid versions offer more extensive libraries of presets for different music genres, headphones, etc.

No spatial audio or surround sound – Paid equalizers often include more advanced features like spatial audio, surround sound, or 3D effects. Free apps typically don’t include these capabilities.

Can’t tweak all frequencies – Some free equalizers limit your ability to adjust specific frequency ranges, while paid options enable full control over the frequency spectrum.

Limited device or format support – Free equalizers may only work on certain devices or audio formats, whereas paid versions are more universally compatible.

Overall, free equalizer apps provide basic EQ adjustment capabilities but lack the more advanced and customizable options available in paid versions. If you require systemwide audio changes or spatial audio effects, a paid equalizer is likely the better choice.

Top Paid Options

Some of the top paid equalizer apps for Android include Poweramp, Neutron, and USB Audio Player Pro (UAPP). These apps offer advanced audio processing capabilities that go beyond what you can get in free equalizers.

Poweramp is widely considered one of the best equalizer apps available with its highly customizable 32-band equalizer and support for playback formats like FLAC, MP3, and more. It allows you to tweak every aspect of your audio experience with individually adjustable bands, presets, playback speed control, stereo expansion, and more as noted in this Reddit thread.

Neutron Music Player also provides a powerful 32-band equalizer along with customizable presets, filtering, and stereo widening effects. It focuses on high-resolution audio playback for those looking for the best possible sound quality.

UAPP aims to provide bit-perfect audio playback with features like gapless playback, on-the-fly DSD conversion, and PCM up to 32 bit/384 kHz. Its 10-band equalizer may be simpler than others but is finely tuned for audiophile-grade listening.

These paid options offer advanced audio processing capabilities that go well beyond basic equalization. If audio quality is your top priority, the enhancements and customizations provided by these apps make them well worth the small purchase price.

Key Features of Paid Apps

Paid equalizer apps offer several advantages over free options, including more extensive features and systemwide audio enhancement capabilities. Some key features of paid equalizer apps include:

  • More bands and presets – Paid apps like Poweramp (1) offer 32 bands compared to the standard 5-10 bands in free equalizers. This allows for more precise audio tuning. Paid apps also have more preset options to optimize audio for different genres.
  • Systemwide audio changes – Paid equalizers can enhance audio from any app on your device, whereas free ones typically only affect music players. Poweramp and other paid apps can boost sound quality across streaming, YouTube, games etc.
  • Spatial and 3D audio effects – Advanced paid equalizers like Boom 3D (2) offer surround sound effects and 3D spatial audio to make music more immersive. These realistic effects are only found in premium apps.
  • Metadata support – Paid apps can read track metadata like album art and allow you to customize settings per-song or per-album. Free equalizers lack metadata capabilities.

With their additional features and device-wide audio tuning, paid equalizer apps offer more flexibility and customization for audiophiles seeking the best possible sound.

Which Option is Best?

There are a few key factors to consider when choosing between free and paid equalizer apps:

Budget – Free apps like Music Volume EQ and Equalizer FX have no monetary cost, making them accessible to everyone. Paid apps like Poweramp can cost up to $5 which may not work for those on tight budgets.

Features – Free apps provide basic EQ with around 5 bands while paid apps offer advanced capabilities like 20-32 parametric bands, preamp, and stereo expand. Paid apps also allow deeper customization.

Devices Used – Free apps often work on Android only while paid apps are available across platforms like Android, iOS, Windows, Mac. If using multiple devices, paid apps provide consistency.

For casual users looking for basic EQ, free apps offer enough. But audio enthusiasts and power users need enhanced tools that paid apps provide. The best free option is Music Volume EQ while Poweramp is the top paid choice. Investing in Poweramp unlocks more precision EQ to truly customize your listening.


In summary, there are several high-quality free equalizer apps that provide robust audio adjustment capabilities for most users’ needs. Apps like Equalizer FX, Music Volume EQ, and Equalizer & Bass Booster offer an array of customization features like bass boost, virtualizer surround sound effects, and preset audio configurations for different genres.

However, paid equalizer apps unlock more advanced functionality like additional bands of parametric EQ, higher quality audio processing, and system-wide audio enhancement. Paid options like Neutron Music Player, Poweramp, and Wavelet offer these premium features for users who need more precision and control.

Ultimately, it comes down to each user’s specific needs and budget. For many, a free equalizer will be sufficient to enjoy customized audio. Audiophiles and power users may benefit more from paid equalizers with more robust capabilities. The wide range of quality free apps makes equalizers accessible for most. But paid equalizers deliver premium quality for those seeking the highest level of audio fine-tuning.
