Improve Audio Quality on Desire HD with Sony xLoud Engine MOD


After the Sony Bravia Engine that was ported over from the Sony Xperia line of Android phones to other Android phones resulting in enhanced image and video quality, it seems it’s now the turn of  the sound enhancement engine found on Xperia phones to be ported over to other devices. The Sony xLoud Engine is a volume enhancement engine that enhances loudspeaker volume while playing music, videos or making a call, and is a feature on many Sony Xperia Android phones.

HTC Desire HD owners can now enjoy the benefit of the xLoud Engine on their devices as well, thanks to this mod by XDA member XxXPachaXxX. While on Xperia phones the xLoud Engine can be turned on and off manually, this mod for the Desire HD doesn’t provide any such option but we’re pretty sure you won’t want to turn it off anyway.
