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.
