[Satoshi Hinuma hits the body!] USB microphone, how does the sound quality change with the cute "SNOWBALL" and the cool "Yeti X"?-AV Watch
Audio test assuming a web conference. Which one is the easiest to hear?
Now, how much difference does the hardware and directivity make between SNOWBALL and Yeti X? I decided to compare it with the built-in microphone of a notebook PC (MacBook Pro 2016) and the action cam that I usually use for web conferences.
The situation during the test using the MacBook Pro used for comparison and the action cam SNOWBALL is like thisFirst, check it out in a Zoom meeting. Two desktop PCs and an air conditioner are running nearby, and there should be continuous fan noise mixed in. It may have been somewhat reduced by Zoom's background noise suppression function ("Low" setting), but what about it?

ノートPCの音声は、ある意味耳慣れた「Web会議らしい」音質のように思える。 It's not hard to hear, but you can hear what seems to be echoes in the room, and it's neither particularly good nor bad. The sound of hitting the keyboard is a clear noise because the microphone is close and the case is connected in the first place.

When it comes to "SNOWBALL (omnidirectional)", you can see that the sound quality is clearly improved. It reproduces a more realistic voice quality and is easier to hear. However, since it is omnidirectional, the fan noise in the background is a little mixed in. The keystroke sound is not as loud as the laptop microphone, but it stands out.
"SNOWBALL (unidirectional)" almost eliminates the background fan noise, and only the voice can be heard clearly. It seems that the keystroke sound of the keyboard is also considerably reduced. Since the microphone is between the keyboard and the author, the advantage of unidirectionality is well utilized.
The next ``unidirectional -10dB'' is just a reduction of the previous unidirectional sound. However, when I start hitting the keyboard, the volume rises to about normal volume. This is probably due to Zoom's automatic volume adjustment function. -10dB doesn't seem to make much sense for web conferencing purposes.
Test situation using SNOWBALL"Yeti X (omnidirectional)" has a higher sound resolution than SNOWBALL. The voice is crisp and easy to hear, but the omnidirectional sound mixes in a bit of room reverberation. When this becomes "Yeti X (unidirectional)", the surrounding noise and echoes are almost eliminated, leaving only the clarity of the voice. However, the keyboard sound does not seem to be reduced as much as SNOWBALL. There is also a sound that picks up the vibration of the desk, so it may be possible to improve it a little by placing an anti-vibration mat under the stand.
"Yeti X (stereo)" has a sound quality that conveys the atmosphere of the space, and you can even tell the size of the room. It's hard to understand the benefits of just one person's voice, but when recording instruments and surrounding sounds, you should be able to reproduce outstandingly good sounds.
The last pattern uses the preset "Broadcaster 2" of "Blue VOICE"And the last "Yeti X (Blue VOICE)" sounds like the voice has a sharper edge. I think it's certainly easier to understand "what you're saying", but I can't get rid of a little "made-up voice". This seems to depend on your taste, but if you value clarity for web conferencing, this mode will definitely be useful.
