This information and technique is rarely shared on the web, but many people may need it. Share the experience here. This is also a problem that has plagued me for a long time. Because I bought this adapter, I found that when I recorded it, the iphone's headphone microphone had a lot of noise that could not be eliminated.First of all, this adapter has been sold in a certain Amoy net.

environment will also pick up the sound, most of the use of the environment noisy sound will be more, so there will be so-called" murmur "phenomenon When this feature is turned off, the noise is eliminated because the voice range of the portable microphone pickup is reduced so that external sounds are not too much picked up. Note 2: " echo cancellation (AEC) ", which eliminates the echo of the speaker in

Failure phenomena: Ideacentre B3 Series integrated microphone with noise Solution: Check to see if an external microphone is used, unplug the external microphone, and use the machine's built-in microphone test. If normal, may be an external

Speakers usually use when everything is normal, but after inserting the microphone, the speaker will immediately generate noise. Microphone and sound card connector line does not use shielding line or shielding line grounding, external high-frequency interference signals by the microphone input string will caus
