Noise may be caused by the physical environment or recording and playback devices rather than the SDK.
Step 1: Self-check
Check the following:
- Ensure that all users are in separated physical environments (no near-field tests).
- Check if an external audio source is used and if the captured external audio source is normal. In this case, noise cancellation is not supported and the noise may be caused by data loss during the audio transmission to the SDK.
- Check if any user is talking in a noisy environment.
- Check if the recording device is working properly. For example, check whether the headset is plugged in correctly, use another headset, or switch to another audio route.
