I don't know why, but there are utilities that allow you to send audio from one application to another. It turned out that it's even necessary for someone. For example, for those who works with digital audio workstations (DAW). So here's the post with this utility.

On macOS

BlackHole is a small utility that helps you to pass audio from one application to another without delay.

The program supports:

  • 16 audio channels with the possibility of increasing to 256 or more.
  • audio frequency 44.1 kHz, 48kHz, 88.2 kHz, 96kHz, 176.4 kHz and 192kHz;
  • work on macOS 10.10+

To start working with BlackHole you need to close all audio apps on the computer to install the utility and reboot the system.

On Windows

Virtual Audio Cable is a tool that will help to redirect the sound between programs. Or record the sound of one application with another.

Virtual Audio Cable is displayed as the output device in the audio system, allowing you to make various manipulations with sound.

Although the app looks outdated, it's actually most effectively to solve the problem. However, to figure out all the settings you need some time.
