Description:
Bass boost is an audio effect to boost low frequencies of the sound.
Treble refers to tones whose frequency or range is at the higher end of human hearing. In music this corresponds to "high notes".
An audio virtualizer is a general name for an effect to spatialize audio channels. A stereo widening effect is used when this effect is turned on.You can get the best sound effect by using a headset.

(*1) Some models do not support the effect on music via the Internet.
Please enable the setting to start a private session in the settings of each music player. This app can use audio sessions broadcast by other apps by turning off the setting item "Global Audio Session Id". Normally, the session is acquired when the song is played. If you turn on "Global Audio Session Id", you can use the effect in Global as an auxiliary. When using with Global, please restart this app after quitting other equalizer apps.
(*2) This app needs to allow microphone permissions to display graphs and activate its own features to get as many Audio Session Ids as possible.
(*3) The maximum gain is set low, but when using it, gradually increase the volume while checking the volume.
In general, sound files have varying volume levels, and some have extremely loud volumes.
