What's New:

Audio Hijack 4.0.4

Improvements in ACE 11.8.3

• The Audio Capture Engine (ACE) has been updated to 11.8.3, with many improvements for even more reliable audio capture. This includes a workaround for issues with FaceTime volume when using the built-in microphone, as well as an improvement in dealing with poorly implemented
• Audio Units. Tracking of audio device sample clocks also now works better when the device is providing erroneous information. CPU usage has been reduced in many common audio flows, clock synchronization across devices has been improved, and persistent device tracking has been improved.
• Substantial improvements have been made to the performance of the “Recordings” list found in each session, to make things work better when a session contains many recordings.
• Left (L) and Right (R) labels have been added to the block face for “VU Meters”.
• Several visual improvemnts have been made for better legibility throughout the app. This includes making active Recorder blocks easier to read, and greatly improving the coloring of selected wires when using manual connections in Light mode.
• Automatic sample rate selection for the “Application” and “System Audio” Input blocks have been improved, with better performance and less resampling.
• Automatic sample rate selection for the “Application” and “System Audio” Input blocks have been improved, with better performance and less resampling.
• Corrections have been made to the “Live Stream” block, to provide better colors in the automatically generated video, and to show a more useful preview even when not broadcasting.
• Fixes have been made to prevent rare issues with the Run/Stop button in the “Sessions List” window.
• An issue where the Recording Inspector could fail to show the genre selector has been corrected.
• An issue where upsampling of certain low sample rates could sometimes produce audio artifacts has been resolved.
• To avoid a rare issue where recordings could be corrupted, Audio Hijack now prevents editing of tags during playback and waveform creation.
• The user interface now indicates when the app is finalizing .m4a files, both in the Recordings tab and when quitting the application.
• The Recording Inspector now better shows in-progress recordings.
• The edit button for renaming blocks now properly moves its position related to the title.
• Renaming a session will now cause the “Session List” window to re-sort.
• The “Denoise” block now properly shows previously learned noises when a session reloads.

• Further improvements are planned for the future.
• Assorted improvements have been made to make timers function more reliably.
• Multiple fixes and improvements have been made for block popovers, to ensure they behave optimally.
• Adjustments have been made to allow the “Quit and Relaunch for Debugging” option to be accessed even on unsupported operating systems, making it possible to activate the “Check for test releases” hidden preference.
• The icon shown in the “Recorder” popover when Audio Hijack is “Ready to Record” has been updated and improved.
• The “Session Start” automation now correctly runs when a timer starts a session. For actions which should run only when a timer fires (and not when a session is started manually), use the “Timer Start” automation.
• Once a session is closed, re-attaching any detached popovers will make the session window reappear.
• When the full version of Audio Hijack has been unlocked, the “License” window now subtly shows the application's version number.
• Fussy typography improvements have been made to the “Release Notes” window shown at the first launch of a new version, which you might be looking at right now!
