Audio noise is generally caused by external environment or recording and playback equipment. It is recommended that developers try the following steps to handle audio noise issues.
Self-Check
Refer to the following operations to confirm whether the noise has been eliminated:
- Confirm whether it is a near-field test: the phones at both ends of the communication are in the same room and in a public address state. When the loop gain is greater than 1, near-field howling will occur.
- Confirm whether the audio uses custom audio collection. Custom audio collection itself will not cause noise, but in the process of transmission to the SDK, noise may be generated due to incomplete data. This mode does not support noise suppression.
- Whether the environment on one side of the call is too noisy. For example, the microphone is facing a computer fan, the room is very noisy, the outside of the window is very noisy, etc.
- Confirm whether the recording device is working properly. For example, external sound cards, headphones, and microphone poor contact can cause electrical noise.
- The microphone on the headphones shaking or rubbing against clothes can also produce noise.
- Mobile phone charging or leakage can also produce electrical noise.

| Information | Details |
|---|---|
| Required Information | The room ID (roomID) where audio noise exists. |
| The user ID (userID) of the audio sender and receiver where the noise occurs. | |
| Optional Information | Audio noise recording file. |
| The specific time period when audio noise occurs. | |
| The ID (streamID) of the stream where stuttering occurs. | |
| Whether the audio noise still exists after exiting the room and re-entering the room. | |
| Whether the test results on macOS or Windows devices are normal. | |
| Whether the audio noise always exists, or only when you speak can you hear the noise, but there is no noise when other users speak. | |
| SDK log file. For details, please refer to How to set and get SDK logs and stack trace information. |
