Quick Overview
Once you have a session hijacked, you can easily record the audio coming from the source. You'll want to adjust the Recordings tab to your desired settings, and then click the Record button. Once Record is active, AH Pro will record all audio coming from the source. The Pause button will stop AH Pro from recording the audio without creating a new file, useful for skipping portions of a program you don't wish to save. The Split button seamlessly starts a new file, which is great for separating a recording into tracks. Finally, clicking Record again ends the recording.
Adjusting Recording Settings
First, adjust the Format pulldown for the audio format in which you'd like to record. MP3 Low or AAC Low will work for most spoken word audio, and MP3 High or AAC High will work for music. If you plan to burn directly to CD, if you experience skipping or if you'd like a perfect, bit-by-bit copy of the audio, use the AIFF or WAV settings. Be aware that these options will create a very large file.
After you've chosen your recording format, adjust the other settings as desired. These settings are fairly straightforward - adjust the destination, the file name, and the post-processing script (if any). The file name setting will allow you to use the Variables popup to name the recorded files. For example, the example in the screenshot of "%n Recording (%d)" results in a file named "RealOne Recording (20040728)".
The Actions area allows you to have AH Pro take certain actions. You can have it start a new file every so often (it will automatically split all files after 2 gigs), stop recording after a set amount of time or disk space, and use the Silence Monitor to have silence removed from files or split when silence occurs.
Finally, the Tags section allows you to add information tags to MP3, AAC, ALAC and AIFF files. WAV does not support any tags.
