The sound quality of microphone and earphones is bad at the online meeting!Many people who are not aware of problems and countermeasures -Shinobu Takahashi Nyan and Windows -Window Forest

Shinobu Takahashi Nyan and Windows

　Since February, I have been working from home for a long time.Recently, when you are busy and many, there are 5 or six online meetings a day, and you may have no break for several hours.It will be helpful if it ends early.Let's put together the meeting.

　If you live in Nyan, there are some meetings that will work well when the meeting camera is shown in the conference camera, so we recommend an online meeting with a catwalk.

The most important thing in the online conference is Mike!

　If there is such an online meeting, you may batting with your family.The other day, my wife was an online seminar assistant next door, but apparently the lecturer's microphone sound quality was bad and it was unpopular among participants.When you actually try an online conference, you have a good trouble.

　Unfortunately, the sound quality of the microphone is difficult to recognize, so it is often difficult to notice.Even if you participate without testing properly, and even if you have a problem after the start of the actual performance, you often do not notice or do trouble shooting.

Mike problem -3 patterns-

　For the time being, let's consider the cause and countermeasures in three cases about the problem involving the microphone.

1. そもそもマイクの音質が悪い
2. Bluetoothのマイクが途切れる/音が歪む
3. Bluetoothのマイクを使うと音が聞こえない、音質が悪くなる

　Since it is an online seminar, I challenge with an external microphone.However, there are many cases where the voice is small or some noise can be heard.So let's check the sound quality of the microphone once.

　First, let's record normally with the Windows "Voice Recorder" app.If the sound quality is bad at this point, the sound quality of the microphone is bad.

　Let's change the location of the microphone once.If you are far away, you will pick up extra sounds.My voice is small and the surrounding noise stands out.Put it close to you.Ideally than the keyboard if possible.

　This video was very helpful.(Especially since around 10:16)

　The microphone of the recent PC has good performance, so let's change it, record and compare.However, if you use a keyboard using a built -in microphone of a PC, the key sound may make you loud.In that case, consider using an external keyboard.

　Headphones for smartphones have many microphone internal organs.The advantage of this method is that the microphone is placed near the mouth.Mostly comes with a smartphone, so let's try it.At this time, a wired type is recommended.

　It is a powerful technique, but it is a certain hand.There are many people who are progressing, but the price is different.When choosing, let's choose this way.

　By the way, be careful with old -fashioned microphones.It is important to note that even if you sell for a long time and have a lot of Amazon's evaluation, the white noise (the sound of "sir" that can be heard when you are not talking) is loud or the volume is small.Be especially careful when the microphone terminal is converted to USB with an adapter.Now that there are many options, it is better to buy a new USB type condenser microphone.

　When I tested it, it was good, but at the time of the online conference, I was told that "noise is not heard".This is common when using a microphone on the Bluetooth headset.This is the load on the CPU.If the load on the CPU increases, the sound may be interrupted due to the processing of Bluetooth.

　The reason why this happens is that Bluetooth processing usually performs a lot of processing in the CPU.At this time, if the CPU is applied to another work, the processing of the Bluetooth may not be done well and the sound may be interrupted or the sound may be distorted.For example, if you use other Bluetooth devices, such as mice and keyboards, you will be more likely to be in the same situation.

　Let's reduce the load on the CPU.When you open the task manager, you can see the running app.Let's reduce the number of apps that are working as much as possible.Pay particular attention to the following apps.The web browser really puts a load on it."OneDrive" adds to both the CPU and the network to synchronize.

　If a browser is absolutely necessary at a seminar, do not open the tab as much as possible.Opening the tab will increase the pounding load.The same is true for the extension.The extension is itself an app in itself.Even if you do not use the extension, it will be loaded just by registering and enabling it.

　Oh, of course, there is a way to use a good PC.

　For example, it is better not to use Bluetooth in the first place.As mentioned above, wired connection, if possible, a USB microphone is recommended.Also, if you use a Bluetooth microphone, you may have an effect if you use a Bluetooth connection mouse or keyboard.

　If you can use a notebook PC touch pad, you may want to change it there.There is also a way to change the Bluetooth headset to a wireless USB connection.A Bluetooth audio receiver is an adapter, and the headset of Bluetooth connection is changed to USB connection.In some cases, the situation will improve.(However, these are almost unusable for the microphone. Mike is required separately, so be careful.)

　This is a profile problem.When using Bluetooth headphones, most of them have two connections (profiles).Headset (HSP) and headphones (A2DP).

　It is monaural when you choose a headset.The headphones are stereo and sound good.Normally, you use headphones to listen to music.

　So far, it's good, but when you use this Bluetooth headphone microphone, there are restrictions.In fact, the microphone is connected by a headset connection, so those who listen to the sound only appear in the headset connection (that is, the sound is monaural).

　Even if you make a stereo connection in this situation, there is no sound.

　I have no body or lid, but it is simple.Let's use a strange microphone.Is it a built -in or external on a PC?In this way, you can connect to the headphones, so the sound of the meeting can be heard neatly with a stereo.

　The PC of the online seminar's organizer is in a harsh environment.

　The load on the PC remains a decrease in communication quality.It is important to create an environment that does not put a load on the PC.For that purpose, it is also an effective means to divide the PC for demonstrations and presentations and distribution / communication PCs separately.

　With Windows 10 projection functions, you can send your PC screen to other Windows 10 PCs.You can also connect from a PC for distribution on a remote desktop.

　In this way, the burden on the PC for distribution can be greatly reduced, so that the communication quality can be reduced as a result.It is a good idea to consider creating such an environment.

　After all, there is one thing to do.Use a wired microphone or headphone microphone.A cheap microphone is useless.If the sound is small, the noise is riding, and if it is poor, the microphone of the PC internal organs is still better.Before the connection, you must check the sound quality with a voice recorder app, and to check the audio check of "Microsoft Teams", "Zoom" and "Skype".I think you can check each time you connect.

　Someday my Nyans will come online.In order to deliver the beautiful voice of Nyanzu, I also have a microphone environment.So I wonder if I can buy a new microphone.That's a good camera from Sony.Don't buy ...?
