"BLACKHOLE" that enables voice recording on a Mac.Recommended for video conference records

　Mac has two OS standard functions for recording the screen.One is to use "QuickTime Player".After launching QuickTime Player, you can record (recording) the screen with "File → New Screen Record".

　The other is "MacOS Mojave (10).14.6) How to use the new functions installed after].From the on -screen control displayed in "Shift + Command + 5", select "Record the entire screen" or "Record the selection part", then click "Record" to start recording.

　This function is very convenient, but there is one drawback.That is, the sound is recorded by the built -in microphone of the Mac.Of course, the surrounding sounds are recorded, and the sound quality is no longer good.

　Therefore, many Mac users have used the virtual audio driver "Soundflower", but the latest "MacOS Catalina (10).15.5) In the case, the old original version of the signature can no longer be installed.That's why I tried the virtual audio driver "Blackhole: Virtual Audio Driver", which has recently gained popularity.

　The installation itself is easy.Click "Download Installer" on the GitHub distribution site, enter your e -mail address and name on the transitioned screen, and then click "Subscribe for Free Mac Download" to arrive.Click the link in the email to open a page to download the latest installer.Right -click the file and follow the instructions to complete the installation.

　Now, even if you install Blackhole, the app icon will not appear in the application launcher "LaunchPad".The settings are set in either "LaunchPad → Other → Audio Midi settings" or "System Environment Settings → Sound".This time, let's explain how to set the former.

　That said, the setting method is not so difficult.First, right -click the item "Blackhole 16ch" and select "Use this sound input device".Next, select "Create multiple output devices" from the " +" icon at the lower left, and check "Use" in the order of "MacBook Pro speaker" (or equipment you want to use for audio output) and "Blackhole 16ch" on the right.Insert.The setting of the Audio Midi setting is now complete.

　Here is one point to note.In the list of audio devices on the right, "Blackhole 16ch" must be placed at the end.If "Blackhole 16ch" is located at the top, you cannot play videos on YouTube on the browser or QuickTime Player.Please note that it is a specification that tends to stumble while changing the settings.

　After starting the web videos, apps, and games you want to record, and click "Record" from the on -screen control displayed in "Shift + Command + 5" described at the beginning, the recording will start.Make sure that "Blackhole 16ch" is selected for sound input with "option" just in case.If it is set correctly, you should be able to record the video, app, game video and audio as it is.

　In fact, there is another point to note.This time, I tried Blackhole in various web videos, apps, and games, but when I tried to record a video with "Asphalt 9: Legends", I selected "Blackhole 16ch" as the sound input device with Audio Midi settings.And BGM can be recorded, but BGM was not played from the speaker.

　If you select "MacBook Pro microphone" (or "built -in microphone") in the sound input device, the BGM will be played from the speaker, but this time you cannot record BGM.There may be other apps and games that have similar phenomena.We recommend that you check voice in advance before starting a production recording.

　The author himself has recently increased online presentations and video conferences.In particular, in online presentations that you do not speak, Blackhole, which can record images with the same sound, seems to be useful.Blackhole, which can extend Mac audio settings, is a virtual audio driver that can be recommended without complaint as a successor to Soundflower.

　If you want to record your voice at a video conference, select "Create a device set" from the " +" icon in the lower left, and "MacBook Pro microphone" (or equipment you want to use for audio input) on the right.Check "Use" in the order of "Blackhole 16ch".Then, when recording video conferences such as "ZOOM", select "Equipment Set" as sound input from "Options" of the on -screen control displayed in "Shift + Command + 5", and start "Recording".The voice and their voice are mixed and recorded.

　If you want to uninstall Blackhole, please refer to this GitHub page.If you execute the command described in "Terminal", you can uninstall Blackhole.
