R1: Woofer Bass Booster

Bring a woofer to your Android screen. R1 is a bass booster that combines low-frequency sound control with a detailed speaker that responds to the bass in your music. Shape your sound with two knobs. INPUT LEVEL adjusts the bass enhancement strength. CROSSOVER FREQUENCY changes the upper range of the bass effect, so you can find the balance that suits your listening. Watch the speaker cone move as music plays. Move the light around the woofer, let it rotate, or lock it at your favorite angle. Light position and knob settings are remembered. Portrait and landscape layouts fit phones and tablets. Play music in your usual player and adjust R1 while listening. Try it with headphones or Bluetooth speakers. Sound enhancement and music visualization depend on your device, player and audio output. Use the woofer effect free for 30 minutes each day. Time counts only while music plays with the effect applied. A one-time in-app purchase removes the daily limit. No subscription. Android requires microphone permission for the speaker animation to follow the music. R1 analyzes internal audio output, not microphone input, and does not record, save or transmit audio. Bass enhancement works without this permission.
