Car audio-DSP

Car audio-DSP is the companion app for SOFEI car audio digital signal processors. It connects to your amplifier over Bluetooth Low Energy and puts the sound of your car in your hand — no extra remote, no buried menus.

WHAT YOU CAN DO
• Volume — set the output from 0 to 32, or mute instantly with one tap.
• Sound effect intensity — fine-tune from 0 to 32 to match your music and your mood.
• 9 sound presets — Normal, 3D Normal, 3D Concert, 3D Bass, 3D Techno, POP, Classic, Live and Club.
• Input source — switch between Bluetooth and RCA without reaching for the amplifier.

BUILT FOR THE DRIVER'S SEAT
• Large, high-contrast controls that stay readable in daylight.
• A rotary knob you can drag for quick, precise changes.
• Text size that follows your system font settings.

STAYS IN SYNC
• Bluetooth Low Energy pairing with automatic reconnect.
• Live status sync — change something on the amplifier and the app follows.
• Remembers your last settings between sessions.

GOOD TO KNOW
• This app controls a compatible SOFEI car audio DSP amplifier. It is not a music player and does not play audio itself.
• On Android 11 and below, Android requires the Location permission to scan for nearby Bluetooth Low Energy devices. The app never collects, stores or shares your location.
• No account, no sign-up, no ads, no in-app purchases.
