Audio Configuration

Configure how Ava captures and processes audio from the microphone.

Compatible with Android 5-16.

0.6.4 extends Software Mic Gain to negative values (attenuation) and splits recording device routing out from the System Recording Mode.

System Recording Mode

Choose how the microphone captures audio:

Mode Description
Auto select Lets the device choose. Best default
Speech boost Tries to make speech clearer. May change tone
Normal pickup Plain microphone input. Safest choice
Call boost More like call audio. May over-process
Unprocessed Closest to raw input. Good for testing

Audio Processing

Option Description
Noise suppression Use device noise suppressor when available
Automatic gain control Use device AGC when available
Hardware echo cancellation Enable hardware echo cancellation when supported
Software echo cancellation Cancel Ava's own playback from microphone so wake words work during music/TTS playback

Software AEC is recommended when using music playback or TTS. It replaces the device echo canceler while enabled.

Software Mic Gain

Adjust PCM audio before wake word detection and streaming. Range: -24 dB to +24 dB (0.6.4; previously 0-24 dB, positive only).

  • Positive values amplify a quiet input
  • Negative values attenuate a microphone that is too loud or captures too much background noise
  • Default remains 0 dB

Recording Device Routing (0.6.4)

Recording device routing is now a separate choice from the System Recording Mode above (Android's AudioSource mode).

Option Description
Auto Let Android pick the input device
Built-in microphone Force the device's built-in mic
USB microphone Force a connected USB mic, with safe fallback to the default input if the requested USB device is unavailable

Path: Ava Settings → Voice Config → Microphone

Thanks to @lone-baggie for requesting explicit USB microphone selection in #157.

Audio Config Presets

Standard 16kHz Mono Default for voice recognition
Broadcast 48kHz Mono Higher quality capture

Low Latency 16kHz Reduced latency
Voice Call Optimized For voice call use case
Unprocessed Raw 48kHz Raw capture, no processing

Voice Channel

The Voice Channel switch disables all voice input, wake word, and voice assistant threads. Service restart required to apply.

Continuous Conversation

Continuous conversation lets you issue multiple commands without saying the wake word each time.

How It Works

  1. Say wake word + first command
  2. After Ava responds, automatically enters listening mode
  3. Say next command directly (no wake word needed)
  4. After 10 seconds of silence, exits continuous conversation mode

End Conditions

Mode Description
Exit Keyword Stop End when the assistant says goodbye or farewell phrases (default)
Question Mark Continue Keep listening only if the reply ends with "?"; stop after other replies

How to Enable

  1. Go to Settings -> Interaction
  2. Turn on Continuous Conversation switch
  3. Choose end condition mode

Conversation Subtitles

Conversation subtitles display what you said and Ava's response on screen as a floating window.

How to Enable

  1. Go to Settings -> Interaction
  2. Turn on Floating Subtitle switch

Mute Mode

Mute mode turns off the microphone, Ava won't respond to any wake words.

How to Enable

Method 1: In Settings

  1. Go to Settings -> Voice Config
  2. Turn on Mute switch

Method 2: Home Assistant Control

service: switch.turn_on
target:
 entity_id: switch.your_device_name_mute
