AutoCodec: Bluetooth Audio

Stop Android from silently resetting your Bluetooth audio quality every time you connect your headphones.

Take full control of your wireless sound with AutoCodec—a precision Bluetooth codec changer, real-time A2DP stream monitor, and intelligent automation utility built for audiophiles, mobile gamers, and everyday listeners.

Whether you want to lock in high-resolution LDAC or LHDC for lossless music, switch to low-latency codecs for competitive gaming, or prevent audio stuttering on crowded Wi-Fi networks, AutoCodec handles it automatically in the background.

KEY FEATURES

1. REAL-TIME BLUETOOTH AUDIO TELEMETRY
See what your Bluetooth connection is actually transmitting in real time while audio is playing:
• Active Codec: Instantly identify the active codec driving your Bluetooth A2DP stream.
• Sample Rate: Monitor live 44.1, 48, 88.2, 96, 176.4, and 192 kHz audio streams.
• Bit Depth: Verify 16-bit, 24-bit, or 32-bit playback depth where exposed by the system.
• Bitrate & Quality Tiers: Track active transmission rates and high-bitrate quality modes.
• Channel Mode: Confirm Stereo or Mono output at a glance.

2. INTELLIGENT ZERO-TOUCH AUTOMATION
Set your rules once and let AutoCodec optimize your Bluetooth stream automatically:
• Connection Automation: Automatically lock your preferred codec, sample rate, and bit depth the instant your headphones, TWS earbuds, DAC, speaker, or car stereo connects.
• Per-App Audio Profiles: Assign custom codec profiles to individual apps. Automatically switch to maximum bitrate for music players and low-latency modes for games or voice calls, then restore your default profile when you exit the app.
• Smart Network-Aware Switching: Eliminate 2.4 GHz Wi-Fi interference. AutoCodec detects your active Wi-Fi band and dynamically adjusts Bluetooth audio parameters on congested 2.4 GHz networks to prevent audio drops, restoring Hi-Res settings on 5 GHz / 6 GHz Wi-Fi or mobile data.

3. BROAD BLUETOOTH CODEC SUPPORT
Inspect, test, and automate a comprehensive range of Bluetooth codecs supported by your phone and connected audio gear:
• Sony LDAC: Full quality-tier control and adaptive bitrate modes.
• Qualcomm aptX Adaptive: Dynamic high-resolution and low-latency configurations.
• Qualcomm aptX & aptX HD: Dependable standard and high-definition wireless audio.
• LHDC (V3 / V5): High-bitrate, high-resolution wireless streaming.
• Samsung Scalable / Seamless Codec (SSC): Supported UHQ and adaptive modes on compatible Galaxy devices.
• LC3 & Opus: Next-generation Bluetooth LE Audio and low-complexity codecs where supported.
• AAC & SBC: Universal Bluetooth codecs with fine-tuned stream parameter controls.

4. DEEP HARDWARE CAPABILITY PROBING & SYSTEM INFO
Wondering which codecs your earbuds and phone truly support?
• Sequential Codec Probing: Test and verify which codec configurations are genuinely accepted by both your phone's Bluetooth stack and your connected audio device.
• Subsystem Diagnostics: Inspect your phone's processor, Bluetooth core specification, LE Audio support, and Wi-Fi / RF coexistence capabilities in one clean dashboard.

5. PRIVACY-FIRST, OFFLINE & MODERN MATERIAL 3 UI
• 100% On-Device Privacy: All automation rules, device profiles, and diagnostic logs stay locally on your device.
• Clean Experience: Zero ads, no account required, and no personal data collection.
• Material You Design: Crafted with native Material 3 and Adaptive layouts for phones, foldables, and tablets.


HARDWARE COMPATIBILITY NOTE

AutoCodec configures and automates codecs available within your device's Android Bluetooth stack. To use a specific codec (such as LDAC, aptX Adaptive, or LHDC), both your Android phone and your connected Bluetooth audio device must support that codec in hardware and firmware.
