Rogue Amoeba (www.rogueamoeba.com) has updated Audio Hijack, the Mac OS X tool for recording and enhancing audio, to version 3.1.

With the utility, audio from individual applications like Safari or Skype, hardware audio devices like microphones and mixers, and even the entire system audio output, can all be saved. In version 3.1, Rogue Amoeba updated the “File Limits” section of the Recorder Block to include a Silence Monitor. Now, users can control just how Audio Hijack reacts to silence in the audio stream. You can remove the silence from a recording, automatically start a new file when silence occurs, or stop the recording based on silence.

The file actions in Audio Hijack can now make quick work of common file tasks. Recordings can be passed over to the user’s chosen audio editor, added to iTunes, or shared use the OS’s built-in Share sheet.

Audio Hijack requires Mac OS X 10.9 or higher. Audio Hijack 3.1 is a free update for owners of Audio Hijack 3. Users who are new to Audio Hijack can unlock the full version for US$49. Also, discounted upgrade pricing of just $25 is still available to all customers who’ve ever purchased a product with “Audio Hijack” in the name.
