OZO Audio Capture Redmi K40 ports recording-preprocessing libraries and effect configuration from the Redmi K40 to compatible Android devices with a HIDL audio stack.
Systemless Recording Preprocessing
The module registers the ported OZO processor for common microphone capture sources; it does not provide a companion app or an equalizer interface.
Capture Sources
Attaches the effect to microphone, camcorder, voice-recognition, and voice-communication preprocessing chains.
Ported Libraries
Supplies 32-bit and 64-bit encoder, processing, and OZO audio libraries together with the required SDK data.
NoMount Support
Version 1.3 can cooperate with NoMount metamodule workflows and restores module permissions during early boot.
Compatibility Requirements
- An ARM64 or ARMv7 Android device.
- A firmware that still uses compatible HIDL audio services and audio-effects configuration.
- Magisk, Kitsune Mask, KernelSU, or APatch as the root-module environment.
- Audio Modification Library only when other audio modification modules are installed concurrently.
How It Integrates
During installation, the module copies the device's available audio-effects configuration into its systemless overlay and adds an ozo preprocessing effect with the supplied UUID. Its boot service enables audio effects through a property and restarts the media, audio, and relevant hardware-audio services so the new registration can be loaded.
Installation
- Install the module through Magisk, Kitsune Mask, KernelSU, or APatch. Recovery installation is documented only for Magisk and Kitsune Mask environments.
- If another audio modification is already present, install Audio Modification Library so both modules can merge audio configuration safely.
- Reboot, then test recording in a basic recorder before evaluating camera, calling, or voice-recognition applications.
Port and Licensing Notes
This is a hardware-specific binary port, so success on the Redmi K40 does not imply universal support. A mismatched audio stack can produce ignored effects, recorder failures, or audio-service restarts. The repository's MIT license covers the module scripts; the bundled OZO binaries remain third-party proprietary components owned by their respective rights holder.
