Bass Booster Equalizer Pro

Cortex App Network

About this app

Cortex Equalizer Pro is a professional Equalizer, Bass Booster, and Volume Booster application designed to maximize the audio potential of your smartphone and headphones. It gathers all the sound engineering tools you need under one roof to surpass the standard volume limits of your device, reveal the finest details in the music you listen to, or enhance the atmosphere of the movies you watch. Developed for those seeking a flawless listening experience, this application puts complete audio control in your hands with its advanced Equalizer frequency bands, a distortion-free Volume Booster infrastructure, and Bass Booster technology that delivers deep, punchy low frequencies.

Thanks to its advanced architecture, it analyzes and optimizes the audio output in real-time while you are listening to music, watching movies, following podcasts, or playing games. Beyond being just a volume enhancer, it offers a professional studio interface where you can completely personalize the character of the sound.

Key Features

10 Band Pro Equalizer
Unlike standard 5-band equalizers, Cortex Equalizer Pro gives you full control over 10 different frequency bands ranging from 31 Hz to 16 kHz. This allows you to adjust the bass, mid, and high frequencies of the audio with pinpoint precision. Shape the frequency curves exactly as you wish to bring vocals to the forefront, clarify drum beats, or make background instruments more distinct.

Advanced Bass Booster and Gain Controls
The application utilizes a special algorithm that amplifies the sound without digital distortion. You can manage three main gain settings using the hardware-inspired rotary knob controls located on the main panel:

Bass Gain: Adds depth and rhythm to the music by boosting the lower frequencies (sub-bass and punchy bass). It is especially ideal for electronic music, hip-hop, and rock listeners.

Mid Gain: Prevents the sound from becoming muddy and provides clarity by balancing the mid frequencies where vocals and lead instruments are located.

High Gain: Adds brightness and acoustic clarity to the sound by enhancing the treble frequencies.

Pro Volume Booster
If the default maximum volume of your device is not enough for you, the Pro Volume feature steps in. Thanks to its safe volume amplification technology, it increases the overall volume level in decibels (dB) without pushing the hardware limits of your speaker or headphones and keeping distortion to an absolute minimum. It is a lifesaver for low-volume recorded videos or podcasts.

Real-Time Audio Engine Spectrum
The Audio Engine Spectrum, which allows you to see the frequency distribution of the audio you are listening to in real-time, offers a dynamic visual experience. This sound-reactive analyzer can be personalized with a full-screen mode and switchable color palettes. You can instantly and visually track the effects of your Equalizer and Bass Booster adjustments on the sound waves.

Quick Modes: With the Movie, Podcast, and Music buttons on the main screen, you can instantly optimize the sound according to the content type with a single touch.

Smart Bedtime Mode
This is a unique feature specially developed for those who like to fall asleep listening to music or podcasts. During the duration you set (15, 30, 45, or 60 minutes), instead of abruptly cutting off the playing sound, the application gradually and slowly fades it down to a -0.2 dB level. Thanks to this gentle fade-down technology, your sleep will not be interrupted by the sound suddenly turning off; as you fall asleep, the music peacefully silences along with you.
