Audio Settings

This page covers the audio configuration options available in Knowii Voice AI. These settings allow you to control audio devices, feedback sounds, and volume levels to create a personalized recording experience.

Devices​

Configure your audio input and output devices for optimal recording quality.

Recording Device​

Location: Settings > Audio > Devices

Select which microphone or audio input device to use for voice recording:

  • Choose from all available microphones on your system
  • Default setting uses your system's default recording device
  • Common options include:
    • Built-in laptop microphones
    • External USB microphones
    • Headset microphones
    • Virtual audio devices

Tips:

  • Use a dedicated external microphone for better audio quality
  • Test different microphones to find which works best for your environment
  • Close to your mouth typically produces clearer recordings
note

If no working microphone is available when you start recording, Knowii Voice AI shows a warning so you know to connect or select one. See Troubleshooting below.

Test Your Microphone​

Location: Settings > Audio > Devices

Not sure if your microphone is working? Use the built-in test to check before you start recording:

  1. Select your microphone in the Recording Device dropdown
  2. Click the Test microphone button
  3. Speak normally - the level bar moves as it picks up sound, and you'll see a "Sound detected" confirmation
  4. Click Stop test when you're done

If the bar stays flat while you talk, the selected microphone isn't capturing audio - try a different device, check it's plugged in, and make sure your system lets Knowii Voice AI use it.

tip

The test only listens for the level - it doesn't record or transcribe anything, and nothing is saved.

Output Device​

Location: Settings > Audio > Devices

Select which audio output device to use for audio feedback sounds:

  • Choose from all available audio output devices on your system
  • Only active when Audio Feedback is enabled
  • Default setting uses your system's default output device
  • Options include:
    • Built-in speakers
    • External speakers
    • Headphones
    • Virtual audio devices

Reset Button: Click the reset icon to quickly restore the default output device.

Feedback​

Control audio feedback sounds that help you know when recording starts and transcription completes.

Audio Feedback​

Location: Settings > Audio > Feedback

Enable or disable audio feedback sounds:

  • Enabled: Plays sounds when recording starts and when transcription completes
  • Disabled: Silent operation with no audio cues
  • When disabled, all other feedback settings are inactive

Benefits of Audio Feedback:

  • Confirms recording has started successfully
  • Notifies you when transcription is complete
  • Provides reassurance without looking at the screen
  • Helpful when multitasking or when the app is minimized

Volume​

Location: Settings > Audio > Feedback

Adjust the volume level for audio feedback sounds:

  • Range: 0% to 100%
  • Increments: 5%
  • Default: 100%
  • Only active when Audio Feedback is enabled
  • Adjusting the slider plays a test sound at the new volume level

Tips:

  • Start at 50% and adjust to your preference
  • Lower volume if working in quiet environments
  • Higher volume useful when working with background noise or music

Start Recording Sound​

Location: Settings > Audio > Feedback

Choose which sound plays when recording begins:

  • Select from available sound files
  • Default: default_start.mp3
  • Only active when Audio Feedback is enabled
  • Preview sounds by adjusting the volume slider

Reset Button: Click the reset icon to restore the default start sound.

End Processing Sound​

Location: Settings > Audio > Feedback

Choose which sound plays when transcription completes:

  • Select from available sound files
  • Default: default_end.mp3
  • Only active when Audio Feedback is enabled
  • Different from the start sound to distinguish between recording and completion

Reset Button: Click the reset icon to restore the default end sound.

Custom Sounds​

Location: Settings > Audio > Feedback

Prefer your own start and stop sounds? You can add them in just a few clicks:

  1. Click the Open Folder button next to Custom Sounds. This opens your custom sounds folder in your file manager, creating it automatically if it doesn't exist yet.
  2. Copy your own .wav or .mp3 files into that folder.
  3. Back in Knowii Voice AI, open the Start Recording Sound or End Processing Sound dropdown - your custom sounds appear in the list, ready to select.

Tips:

  • Keep custom sounds short (a fraction of a second) so they don't overlap with your recording.
  • Your custom sounds stay on your computer - nothing is uploaded anywhere.

Common Scenarios​

Quiet Office Environment​

  • Enable Audio Feedback for subtle confirmation
  • Set Volume to 30-50%
  • Use default sounds (designed to be unobtrusive)

Noisy Environment​

  • Enable Audio Feedback for clear confirmation
  • Set Volume to 80-100%
  • Consider using a headset for both recording and feedback

Silent Operation​

  • Disable Audio Feedback completely
  • Rely on visual overlay instead (see Advanced Settings)

Recording Meetings​

  • Use external microphone for better quality
  • Disable Audio Feedback to avoid disturbing others
  • Check overlay position is set appropriately

Troubleshooting​

No Sound is Playing​

  1. Verify Audio Feedback is enabled
  2. Check Volume is above 0%
  3. Verify correct Output Device is selected
  4. Check system volume is not muted
  5. Test with different sound files

Microphone Not Detected​

  1. Ensure microphone is properly connected
  2. Check system audio settings recognize the device
  3. Try disconnecting and reconnecting the microphone
  4. Restart Knowii Voice AI
  5. Check microphone permissions in system settings

"Couldn't start recording" Warning​

If you press your shortcut and see a warning that recording couldn't start, Knowii Voice AI wasn't able to use a microphone. To fix it:

  1. Open Settings > Audio > Devices and select a Recording Device
  2. Make sure the microphone is connected and working in other apps
  3. If you just plugged in a microphone, restart Knowii Voice AI so it appears in the list
  4. Check that your system allows Knowii Voice AI to access the microphone

Wrong Device Selected​

  1. Use the Recording Device dropdown to select the correct microphone
  2. Use the Output Device dropdown to select the correct speakers/headphones
  3. Click reset buttons to restore system defaults
  4. Restart the app if devices don't appear

Audio Feedback Too Loud/Quiet​

  1. Adjust the Volume slider in Audio Settings
  2. Check system volume level
  3. Check output device physical volume controls
  4. Try different output devices

Tips​

  • Test your audio settings before important recordings
  • Keep Audio Feedback enabled initially until you're comfortable with the app
  • Use the volume slider to preview sounds at different levels
  • Different microphones can significantly affect transcription quality
  • External microphones typically provide better results than built-in ones
