3. INTELLIGENT AUDIO AUTOMATION

Create rules that automatically apply your preferred Bluetooth audio configuration when supported by your device.

Connection Automation
Apply preferred codec and audio parameters when compatible headphones, DACs, speakers, or car audio systems connect.

Per-App Audio Profiles
Use different Bluetooth audio preferences for different apps. For example, use a higher-bitrate configuration for music apps and a low-latency configuration for games, then restore your default profile when the app is closed.

Network-Aware Switching
Detect the active Wi-Fi frequency band and adjust configured Bluetooth audio settings to help reduce potential interference-related stuttering on 2.4 GHz Wi-Fi. Restore higher-quality settings when using 5/6 GHz Wi-Fi or mobile data.

4. ACTIVE CODEC CAPABILITY PROBING

Investigate which Bluetooth codecs and configurations are actually available through your device and connected audio hardware.

AutoCodec can test supported codec configurations where Android and the device's Bluetooth stack allow it, helping identify supported parameters and save confirmed capability information locally.

5. OFFLINE-FIRST & PRIVACY-FOCUSED

AutoCodec is designed to keep your information on your device.

• Preferences and diagnostic logs are stored locally.
• No account required.
• No ads.
• No personal data collection.
