How to reduce the K669 self-noise or background sound without using any software or plugin?
Take a look at these steps:
š¤Background Sound
Turn the mic back to the noise source.
Go to computer sound settings and turn down the volume level of the input and output to around 50%-75%.
Adjust the on-board volume to 50%-75% and put the mic close to your mouth (about 3āā).
Spend 15 bucks on an arm stand (A bit expensive way)
šļøHumming/Hissing/Static
Restart your computer and plug the mic into another USB port.
Keep smartphones, tablets, routers, etc, away from the mic; especially don't place electronics on the cable of the mic.
It's better not to connect other electronic devices to the power outlet thatās powering the computer.
Go to computer sound settings and turn down the volume level of the input and output to around 50%-75%. Adjust the on-board volume to 50%-75% and put the mic close to your mouth (about 3āā).
Keep your microphone at a suitable angle to avoid breathing air below the mic capsule (45 degrees)
For the latest Windows users, in order to access the sound settings, please right-click the speaker icon at the bottom right-choose "Sound", and click "Sound Control Panel" at the upper right of the pop-up window.
K669B picks up sound from the computer speakers during the Zoom calls. How to reduce such echo noises?
Instead of using speakers, either internal or external, please use headphones or earbuds to connect to your computer. Then the mic will not pick up sound from the output device, thus no more echo will be heard.
Double Voice/Delay:
It may be caused by the monitor or voice enhancement function on the PC and software:
For Windows 10, open āSound Settingsā and click āSound Control Panelā. Click the "Recording" tab, choose "USB PnP Audio Device". Then click "Properties". Click the "Listen" tab, then uncheck the "Listen to this device".
For Windows 11, open āSound Settingsā and choose āMore Sound Settingsā. Click the "Recording" tab, choose "USB PnP Audio Device", then click "Properties". Click the "Listen" tab, then uncheck the "Listen to this device".
For chatting software, like Discord, click the settings icon first. Choose āVoice & Videoā and uncheck the āEcho Cancellationā. Choose the āNoneā option in āNoise Suppressionā.
For recording software, like Audacity, click the "Tracks" tab and uncheck the "Keep tracks synchronized (Sync-Lock)".
Feedback/Echo
It may be caused by the echo of your empty room or the improper audio device settings:
Place some furniture or acoustic foam, if necessary, and avoid an empty recording room. Try to set the speaker away from the mic and don't point the mic capsule at the speaker directly.
Use a headset as an output device if necessary.
How can I reduce the echo sound that it picks up?
Although echo or reverb is always the result of the mic picking up sound twice or more, there are quite a few situations that cause it. So it's more effective to find out why, then fix it.
1ļøā£āEnabled the monitoring feature of system audio. For those mics without a live-time headphone jack, enabling the monitoring feature in the system audio settings can only cause echo most of the time.
Since the mic playback is quite laggy on the computer, because to the double signal conversion.
If you use a mic without a live-monitoring headphone jack, it's just better to playback audio only after the recording.
2ļøā£āEnabled sound effects on the software or system audio settings. Features such as the "Echo Cancellation" of Discord or the "Audio Enhancement" of the system audio settings can only make the audio worse in most cases. Since those settings themselves are too basic to adjust your voice accordingly, it always ends up being either too aggressive or too modest.
3ļøā£āSpacious use environment. If you use a sensitive condenser microphone in a large room, it's quite easy for it to pick up the sound bouncing off the wall, which is more commonly known as the echo.
The treated environment is not possible for most users, though you can still make the place where you put your mic enclosed with some shelves or furniture, but it could be more straightforward and more effective to use in a smaller room.
4ļøā£āMonitor mic audio on the speaker. Even though the mic you use a mic with a real-time headphone jack, you hear even more echo if the default monitoring device is a pair of speakers. Then the mic sound from speakers will be picked up noticeably by the mic, and played back through speakers, and picked up by the mic again and again.
Thus, if you want to hear the mic sound properly, it's better not just to get a mic with a latency-free monitoring feature, but to play back the real-time mic sound through a pair of headphones.
