Improving audio quality

Position your microphone

• For an in-person consultation, place the microphone where it can pick up both your voice and your patient's voice. Keep its openings clear of papers or other objects.
• Use a stable surface and avoid touching or moving the microphone while recording.
• Adjust its position for your microphone and room. Listen to a test from each speaking position to check that neither voice sounds too distant.

You can test the microphone built into your computer or an external microphone you already use. Compare the sound in your usual setup before deciding whether you need different equipment.

Reduce background noise

• Close doors and windows when possible to reduce outside noise.
• Keep the microphone away from fans and other steady noise sources. Reduce these noises when practical, while keeping the room comfortable.
• Avoid placing papers or a keyboard right next to the microphone. Paper rustling, tapping and typing can make voices harder to hear.

Speak naturally

• Speak at your normal pace and volume; there is no need to shout into the microphone.
• Avoid speaking over each other when possible, and pronounce important terms clearly.

Listen to a test before your consultation

1. On the session page, open Microphone in Session capture, then choose Test my microphone. Do this before starting the session recording.
2. Select the microphone you want to use. If needed, click Allow microphone access or Refresh microphones, then follow the permission request.
3. Click Start the test and say a few ordinary sentences from the positions where people will sit. Check that the Sound level meter reacts to your voice.
4. Click Stop the test, then play the audio under Play back the clip. Check that the voices are audible, clear and uninterrupted.
5. Adjust the setup if needed and choose Run another test. When you are satisfied, click Back to return to the session.

The microphone selected for the test is also used for your next session recording. Testing is unavailable while a session recording is active.

This test lets you listen to a short clip on your device. It does not create a session recording or generate a transcript or report. A moving sound meter indicates captured sound; listening to the clip is what lets you check its clarity.

If the sound is not clear

• If a voice is too quiet, check the selected microphone and adjust its position, then repeat the test.
• If you hear crackling, interruptions or strong background noise, check the microphone's connection and reduce nearby noise before trying again.
• If the selected microphone is unavailable, reconnect it or explicitly select another microphone, then use Refresh microphones. Follow any permission or device error shown by Delta.

Repeat the check when you change microphone or room. If the problem persists, contact our team using the help block below and describe what you hear or the error displayed.
