How to Download and Install Soundflower-2.0b2.dmg on Mac

If you want to record the internal audio from your Mac, such as the sound from a video game, a web browser, or a music player, you might have encountered some difficulties. Most audio recording software can only capture the sound from your microphone or an external device, but not from your system itself. This is where Soundflower comes in handy.

What is Soundflower and why do you need it?

Soundflower is a free audio routing software for Mac

Soundflower is an open source kernel extension for Mac OS X that allows applications to pass audio to other applications. It creates a virtual audio device that can act as both an input and an output. In other words, it lets you send and receive audio from different sources without any additional hardware or cables.

Soundflower lets you record internal audio from any app or device

With Soundflower, you can record any sound that is playing on your Mac, whether it is from an app, a website, or a device connected to your Mac. For example, you can use Soundflower to record the audio from a Skype call, a YouTube video, a Spotify playlist, or a DVD player. You can also use Soundflower to record sounds from outside sources, such as a USB microphone or a guitar.

Soundflower is compatible with various audio recording and editing software

Soundflower works well with many popular audio recording and editing software, such as QuickTime, Audacity, GarageBand, Logic Pro, OBS Studio, and more. You can use these software to capture, edit, mix, and export the audio recorded with Soundflower. You can also use these software to add effects, filters, transitions, and other enhancements to your audio.

How to download Soundflower-2.0b2.dmg from a reputable source?

Download Soundflower-2.0b2.dmg from GitHub or SourceForge

The latest version of Soundflower is Soundflower -2.0b2.dmg, which was released on July 8, 2014. You can download it from the official GitHub repository or from the SourceForge website. Both sources are reliable and trustworthy, and they provide the same file. The file size is about 1.4 MB and the file name is Soundflower-2.0b2.dmg.

Verify the file size and checksum of the downloaded file

Before you open the downloaded file, you should verify that it is not corrupted or tampered with. You can do this by checking the file size and the checksum of the file. The file size should be exactly 1,417,216 bytes (1.4 MB) and the checksum should be SHA-256: 6b7e1d7c1735f2b0fbd9f7289cbdbd37c05a8bf01d0e94d36efb9788d594e648. You can use various tools to check the file size and checksum, such as Finder, Terminal, or online services. If the file size or checksum does not match, you should delete the file and download it again from a different source.

Avoid downloading Soundflower from unknown or suspicious websites

While Soundflower is a free and open source software, some websites may try to trick you into downloading fake or malicious versions of it. These versions may contain viruses, spyware, adware, or other unwanted programs that can harm your Mac or compromise your privacy. You should avoid downloading Soundflower from unknown or suspicious websites, such as those that ask you to pay for it, require you to register or sign up, or offer additional downloads or bundles. You should also avoid clicking on pop-ups, banners, or links that claim to offer Soundflower or similar software.

How to install Soundflower-2.0b2.dmg on Mac OS X 10.5.8 or later?

Disable GateKeeper temporarily to open the Soundflower.pkg installer

GateKeeper is a security feature of Mac OS X that prevents you from opening applications that are not downloaded from the App Store or identified developers. Since Soundflower is not signed by an identified developer, GateKeeper may block you from opening the Soundflower.pkg installer. To bypass this, you need to disable GateKeeper temporarily by following these steps:

Go to System Preferences > Security & Privacy > General.

Click on the lock icon at the bottom left corner and enter your administrator password.

Under "Allow applications downloaded from:", select "Anywhere".

Click on "Allow From Anywhere" in the confirmation dialog.

Close System Preferences.

Now you can open the Soundflower.pkg installer by double-clicking on it. You will see a warning message that says "Soundflower.pkg is from an unidentified developer. Are you sure you want to open it?". Click on "Open" to continue.

Follow the installation steps and allow the Soundflower kernel extension

The installation process of Soundflower is very simple and straightforward. You just need to follow these steps:

Click on "Continue" in the introduction screen.

Click on "Continue" in the read me screen.

Click on "Continue" in the license agreement screen.

Click on "Agree" in the license agreement dialog.

Click on "Install" in the installation type screen.

Enter your administrator password and click on "Install Software".

Wait for the installation to complete.

During the installation, you may see a dialog that says "System Extension Blocked". This means that Mac OS X has blocked the Soundflower kernel extension from loading because it is not signed by an identified developer. To allow it, you need to follow these steps:

Click on "Open Security Preferences" in the dialog.

Click on the lock icon at the bottom left corner and enter your administrator password.

Click on "Allow" next to "System software from developer 'MATT INGALLS' was blocked from loading".

Close System Preferences.

This will enable the Soundflower kernel extension and allow it to work properly.

Restart your Mac and check if Soundflower is installed correctly

After the installation is finished, you need to restart your Mac for the changes to take effect. To restart your Mac, click on the Apple menu at the top left corner and select "Restart".

Once your Mac has restarted, you can check if Soundflower is installed correctly by going to System Preferences > Sound. You should see "Soundflower (2ch)" and "Soundflower (64ch)" as options for both input and output devices. You can also check if Soundflower is working by opening the Soundflowerbed app, which is located in the Applications folder. The Soundflowerbed app allows you to control the volume and mute settings of Soundflower, as well as to monitor the audio signals of each channel.

How to use Soundflower to record internal audio on Mac?

Set Soundflower as the output device in System Preferences > Sound

To use Soundflower to record internal audio on Mac, you need to set it as the output device for your system. This will route the audio from your system to Soundflower, which can then be captured by your audio recording software. To set Soundflower as the output device, follow these steps:

Go to System Preferences > Sound.

Click on the "Output" tab.

Select "Soundflower (2ch)" or "Soundflower (64ch)" depending on how many channels you want to use.

Adjust the output volume slider if needed.

Close System Preferences.

Note that setting Soundflower as the output device will prevent you from hearing the audio from your speakers or headphones. To hear the audio while recording, you need to use a multi-output device or a virtual audio device, which will be explained later.

Choose Soundflower as the input device in your audio recording software

Next, you need to choose Soundflower as the input device in your audio recording software. This will allow your software to receive and record the audio from Soundflower, which is coming from your system. The steps for choosing Soundflower as the input device may vary depending on the software you are using, but here are some general steps:

Open your audio recording software.

Go to the preferences or settings menu of your software.

Find the option for selecting the input device or source.

Select "Soundflower (2ch)" or "Soundflower (64ch)" depending on what you chose as the output device.

Adjust the input volume or gain if needed.

Close the preferences or settings menu of your software.

Now you are ready to record internal audio on Mac with Soundflower and your audio recording software.

Start playing the audio source and record it with your software

The final step is to start playing the audio source that you want to record and start recording it with your software. The audio source can be any app, website, or device that is playing sound on your Mac, such as a video game, a web browser, or a music player. The steps for starting and stopping the recording may vary depending on the software you are using, but here are some general steps:

Start playing the audio source on your Mac.

Switch to your audio recording software.

Click on the record button or press the keyboard shortcut to start recording.

Wait for the recording to finish or stop it manually when you want.

Click on the stop button or press the keyboard shortcut to stop recording.

Save, edit, or export your recorded audio file as desired.

Congratulations! You have successfully recorded internal audio on Mac with Soundflower and your audio recording software.

Optionally, use a multi-output device or a virtual audio device to hear the audio while recording

If you want to hear the audio from your speakers or headphones while recording it with Soundflower, you need to use a multi-output device or a virtual audio device. A multi-output device is a feature of Mac OS X that allows you to send audio to multiple devices at once. A virtual audio device is a third-party software that creates a virtual sound card that can act as both an input and an output device. Here are some examples of how to use these options:

- To use a multi-output device, follow these steps: - Go to Applications > Utilities > Audio MIDI Setup. - Click on the "+" button at the bottom left corner and select "Create Multi-Output Device". - Check the boxes next to "Soundflower (2ch)" or "Soundflower (64ch)" and your speakers or headphones. - Optionally, right-click on the multi-output device and select "Use This Device For Sound Output" and "Play Alerts And Sound Effects Through This Device". - Close Audio MIDI Setup. - Go to System Preferences > Sound and select the multi-output device as the output device. - Now you can hear the audio from both Soundflower and your speakers or headphones. - To use a virtual audio device, follow these steps: - Download and install a virtual audio device software, such as Loopback, Sound Siphon, or Audio Hijack. - Open the virtual audio device software and create a new virtual device. - Add Soundflower and your speakers or headphones as sources for the virtual device. - Optionally, adjust the volume and balance of each source. - Close the virtual audio device software. - Go to System Preferences > Sound and select the virtual device as the output device. - Now you can hear the audio from both Soundflower and your speakers or headphones.

How to troubleshoot common issues with Soundflower?

Check if Soundflower is up to date and compatible with your Mac OS version

One of the possible reasons why Soundflower may not work properly is that it is outdated or incompatible with your Mac OS version. Soundflower-2.0b2.dmg is the latest version of Soundflower, but it was released in 2014 and it may not work well with newer versions of Mac OS, such as Catalina or Big Sur. To check if Soundflower is up to date and compatible with your Mac OS version, follow these steps:

Go to Applications > Utilities > Terminal.

Type kextstat grep -v com.apple and press Enter.

Look for com.Cycling74.driver.Soundflower in the output.

If you see it, check the version number next to it. It should be 1.6.7, which is the latest version of Soundflower.

If you don't see it, or if the version number is lower than 1.6.7, you need to update or reinstall Soundflower.

If you see an error message that says kextstat: command not found, you need to install Xcode Command Line Tools first by typing xcode-select --install and pressing Enter.

If you need to update or reinstall Soundflower, you can follow the steps in the previous section on how to download and install Soundflower-2.0b2.dmg on Mac.

Check if your audio recording software supports Soundflower or has alternative options

Another possible reason why Soundflower may not work properly is that your audio recording software does not support Soundflower or has alternative options for recording internal audio. Some audio recording software may have built-in features or plugins that can capture internal audio without using Soundflower. For example, QuickTime can record internal audio by selecting "New Screen Recording" and choosing "Internal Microphone" as the input source. Audacity can record internal audio by installing the Soundflower plugin and selecting "Soundflower (2ch)" or "Soundflower (64ch)" as the input source. OBS Studio can record internal audio by adding an "Audio Output Capture" source and choosing "Soundflower (2ch)" or "Soundflower (64ch)" as the device. To check if your audio recording software supports Soundflower or has alternative options for recording internal audio, follow these steps:

Open your audio recording software.

Go to the help menu or documentation of your software.

Search for keywords such as "internal audio", "system audio", "Soundflower", or "audio routing".

Read the instructions or tutorials on how to record internal audio with your software.

If your software does not support Soundflower or has alternative options, try using them instead of Soundflower.

If you still want to use Soundflower with your audio recording software, make sure that you have selected Soundflower as the input device in your software preferences or settings, as explained in the previous section on how to use Soundflower to record internal audio on Mac.

Check if your audio source is playing at a normal volume and quality

A third possible reason why Soundflower may not work properly is that your audio source is playing at a low volume or a poor quality. This can affect the sound quality and volume of the recorded audio. To check if your audio source is playing at a normal volume and quality, follow these steps:

Open your audio source app, website, or device.

Play some sound and listen carefully.

Adjust the volume slider or knob of your audio source until it is loud enough but not distorted.

If possible, choose the highest quality or bitrate option for your audio source, such as HD, HQ, or 320 kbps.

If your audio source is still playing at a low volume or a poor quality, try using a different audio source or a different app, website, or device.

If you have adjusted the volume and quality of your audio source, make sure that you have also adjusted the output volume of Soundflower and the input volume of your audio recording software, as explained in the previous section on how to use Soundflower to record internal audio on Mac.

Check if your audio settings are correct and consistent across apps and devices

A fourth possible reason why Soundflower may not work properly is that your audio settings are incorrect or inconsistent across apps and devices. This can cause conflicts, errors, or feedback loops that can prevent Soundflower from functioning properly. To check if your audio settings are correct and consistent across apps and devices, follow these steps:

Go to System Preferences > Sound and make sure that Soundflower is selected as the output device and that the output volume is not muted or too low.

Open your audio recording software and make sure that Soundflower is selected as the input device and that the input volume or gain is not muted or too low.

Open your audio source app, website, or device and make sure that the sound is not muted or too low.

If you are using a multi-output device or a virtual audio device, make sure that Soundflower and your speakers or headphones are selected as sources and that the volume and balance of each source are not muted or too low.

If you are using an external device, such as a USB microphone or a guitar, make sure that it is connected properly and that the volume and quality of the device are not muted or too low.

If you are using any other apps or devices that may affect your audio settings, such as a sound enhancer, an equalizer, a mixer, or a Bluetooth device, make sure that they are configured properly and that they are not interfering with Soundflower.

If you have checked and adjusted your audio settings across apps and devices, make sure that you have also restarted your Mac or reinstalled Soundflower if necessary, as explained in the previous section on how to install Soundflower-2.0b2.dmg on Mac.

Restart your Mac or reinstall Soundflower if necessary

A fifth possible reason why Soundflower may not work properly is that it has encountered a glitch or a bug that can only be fixed by restarting your Mac or reinstalling Soundflower. Sometimes, restarting your Mac can clear any temporary issues or conflicts that may affect Soundflower. Other times, reinstalling Soundflower can fix any corrupted or missing files that may prevent Soundflower from working. To restart your Mac or reinstall Soundflower, follow these steps:

To restart your Mac, click on the Apple menu at the top left corner and select "Restart". Wait for your Mac to restart and check if Soundflower is working.

To reinstall Soundflower, follow the steps in the previous section on how to download and install Soundflower-2.0b2.dmg on Mac.
