About this app
Microphone to Speaker routes audio from your device's microphone to its speakers or connected audio devices. Use it for presentations, voice amplification, or as a simple PA system.
Key Features:
" Echo Cancellation - Choose between hardware-based or software-based echo cancellation to reduce feedback between microphone and speakers
" Audio Filters - Apply high-pass and low-pass filters to remove unwanted frequencies and improve audio clarity
" Device Selection - Select specific audio input and output devices including built-in speakers, earpiece, Bluetooth headsets, USB audio interfaces, and wired headphones
" Audio Recording - Record your microphone input to WAV files for later review or archival
" Audio Playback - Play back recorded audio files through your selected output device
" Background Operation - Continue routing audio even when the app is in the background or screen is off
" Volume Control - Adjust output volume independently from system volume
" Media Audio Mixing - Play music or other media while routing microphone audio
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
" Test audio equipment or microphone setups
" Accessibility tool for voice amplification
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.
