Ringtone Equalizer в Android Market

Ringtone Equalizer (v. 1.0) Разработано Speed Software

*** ROOT only ***

Allows the HTC built-in graphic equalizer to be adjusted for ringtones and any other sound played through the phone speaker.

Unfortunately headphone output isn't affected but it's great for adjusting the sound of musical ringtones.

Requires an HTC phone (G1, Magic, Hero etc) and root access.
