Audio Hijack for Mac

What's new in this version:

Audio Hijack 4.4.4
- Full Support for macOS 15 (Sequoia). Audio Hijack now offers full support for MacOS 15 (Sequoia), with no known incompatibilities
- The “Mixer” block’s VoiceOver accessibility labels have been improved
- A rare crash when using devices with mismatched sample rates has been fixed
- Audio will now mute as expected when running the latest versions of SoundSource alongside Audio Hijack
- The same hotkey can be no longer incorrectly be set for multiple actions
- The license unlock sound now plays via the “systemsoundserverd” process, which correctly respects the system’s alert volume and device preference
- The name of the “Background Sound” special source has been corrected to “Background Sounds”


Audio Hijack 4.4.3
- Preliminary Support for MacOS 15 (Sequoia) Betas. Audio Hijack will no longer warn every launch when run on MacOS 15 (Sequoia). There are no known issues on Sequoia at present, but do note that these betas remain in flux. To avoid problems, we always encourage users to stick with Apple’s official (non-beta) OS releases.
- Return of the “Text to Speech” Special Source. The “Text to Speech” special source has returned, to capture speech audio from applications which do not directly play generated speech (typically triggered by the “Start Speaking” command in the “Speech” menu) via their own process.
- Improvements to Special Sources. The “Siri” special source now correctly includes sound effects on MacOS 14 (Sonoma), and the “VoiceOver” special source has been optimized to capture only necessary processes
- Undo now properly handles adjustments to the On/Off switch on blocks in all cases, as well as wire deletions
- Several accessibility improvements have been made for VoiceOver users, including several enhancements to the “Parametric EQ” block, corrections to readings of the “Application” block, and improvements to reading of block names to make it clearer that they can be edited..
- Previously, it was incorrectly possible to delete a built-in script from the “Script Library” (it would return upon relaunch). That deletion is now disallowed
- The main “Session List” window will no longer incorrectly appear when opening the “About” or “Quick Tour” windows


Audio Hijack 4.4.2
- Corrections for Default Settings for VoIP apps in the New “Audio Device Selection” Section of the “Application” Block
- This update fixes a critical issue where attempting to capture from a VoIP app like Zoom or Skype could result in no audio being recorded. Due to an incorrect migration of existing sessions from Audio Hijack 4.4.0 or earlier, setups where a VoIP app was playing to a non-default output would not see any audio.
- Audio Hijack now correctly defaults the “Audio Device Selection” option to “Capture audio played to all output devices” for VoIP applications. Thanks to Jason Snell for the heads-up on this issue.
- The “What’s New” notes will once again properly display on the first launch of a new version. This fixes a regression introduced in version 4.4.1.


Audio Hijack 4.4.1
- Enhanced Audio Capture for “Application” Blocks via the New “Audio Device Selection” Section
- The “Limit audio capture” setting previously found under the “Advanced” setting in “Application” blocks, has been transformed into a new and more powerful “Audio Device Selection” section.
- These updated controls now offer more refinement over how audio is captured from applications, including channel-level fine-tuning. This is particularly useful for apps which can play audio output to multiple devices, such as “djay”, “Radiologik”, and our own “Farrago”.
- Audio capture via the “Application” block now defaults to capturing just audio played to the system‘s default audio output device. In nearly all instances, this will be what is desired. When it’s not, the new “Audio Device Selection” section of the “Application” block can be adjusted to get the desired audio.
- If you’re running the latest version of Audio Hijack when you check for an update, the resulting information screen now provides a helpful “View Release Notes” button.
- Capture of audio played to secondary devices by VOIP applications has been improved.
- Elements in the LCD area of a session will no longer incorrectly overlap at small sizes.
