Settings:
The app provides multiple echo cancellation modes to suit different scenarios:
- Hardware mode uses your device's built-in echo cancellation
- Software modes provide alternative processing algorithms
Audio filters help reduce feedback and improve clarity:
- High-pass filter removes low-frequency rumble and handling noise
- Low-pass filter removes high-frequency hiss and interference
Use Cases:
" Amplify your voice during presentations or speeches
" Record audio for documentation or reference
" Use your device as a microphone for another audio system

Important Notes:
This app processes audio through your device, which introduces some delay between microphone input and speaker output. The amount of delay depends on your device's hardware and Android version. Echo cancellation helps reduce feedback, but proper speaker placement and volume adjustment may be needed to prevent feedback loops.
The app requires microphone permission to capture audio, storage permission for recording files, and notification permission for background operation.
Privacy:
Audio is processed only on your device. Recorded files are stored locally on your device. No audio data is transmitted to external servers.
