The ultimate listening experience comes from detailed sound.

Gaudio ELEQ allows listeners to hear detailed sound including
deep bass and hi-hat even in the lower volume.


Rich bass even in lower volume.

Gaudio ELEQ(Equal-Loudness-based dynamic Equalizer) is inspired by the psycho-acoustic relationship between frequency and loudness level. It applies an ELEQ filter to an audio signal depending on user setting volume and loudness information derived from input audio signal analysis.

Why do people enjoy louder volume? 

The human ear perceives loudness of a sound depending on its frequency. According to the “Equal-Loudness Contour” model, the louder we listen to music, we can hear the sound better at low and high frequency, which makes people turn the volume up.

Make listening safe, yet fulfilling the demand of Hi-Fi.

Gaudio ELEQ allows listeners to hear a detailed sound, including deep bass and hi-hat even in the lower volume. Therefore end consumers do not need to make the volume loud to enjoy the detailed sound, which follows the World Health Organization’s initiative of “Make Listening Safe” to defeat the high risk of developing hearing loss from unsafe listening practice.

The ELEQ filter is optimally designed to compensate for the difference in the perceptual frequency sensitivity of a human at a present reproduction loudness level. Consequently, even at a lower volume level, Gaudio ELEQ enables to reproduce every detail of the sound as if the audio is played at the maximum volume.
