Soundflower For Mac

Soundflower is a macOS kernel extension that creates virtual audio input and output devices which can be used to transfer a sound signal between various applications. It comes with an easy-to-use menu bar app that allows you to configure the settings and send the audio signal to specific devices.

Note that the Soundflower extension is signed, but the installer is not! You will have to hold the control key down to open the Soundflower.pkg installer for the first time.

The main advantage offered by Soundflower is its simplicity. Essentially, all you need to do is follow the installation procedure, and you are good to go. The created 2-channel and 64-channel devices can now be used as the default input or output devices in various applications.

For example, if you want to send audio from iTunes to another app, you can set one of the two Soundflower devices as the default sound output and configure the second tool to use it as its input device.

The package includes Soundflowerbed, a lightweight app that rests in your menu bar and provides you with a quick and easy method of routing sound to various devices. You can also use it to change the default buffer size and manage channels individually.

For more in-depth customization, you can alter the volume of specific channels, mute them or change the audio format.

Soundflower is very lightweight and uses a very low amount of system resource, partly because the configuration tool does not need to be running for the virtual audio devices to be usable.

To conclude, if you are looking for a straightforward way to transfer an audio signal between multiple applications, for various purposes, Soundflower can help you out. It creates two virtual audio devices that can be used as the input and output in certain apps and comes with an intuitive configuration tool.
