To stop your recording, click the Record button again. To hear the results of your work, click the Recordings button at the bottom-right of the window, select your recording, and click its Play button. (You can also tag recordings within this area.) There's no need to save your recording as it's done on the fly.
It's about the flexibility
As with previous versions, Audio Hijack 3 lets you manipulate audio before it's recorded. For example, you've hung on to your vinyl collection and you'd like to digitize it. You're aware that records occasionally pop and click and you'd prefer to have those sounds filtered out. You can do that by inserting a Declick effect between the Source and Output block. Or you have a microphone that records only on the left channel and you'd like it to be mono across both the left and right channels. Just insert a Channels effect after the Input Device block and choose its Mono option.
And you're not limited to one source and one destination per session. If you're recording a podcast with a multi-channel interface, for example, you can direct each channel to record to a separate file, which you can then mix in an audio editing app. Or you could record each channel (or multiple recording devices) to a single track, mixed together.
And speaking of podcasts, there's Skype and its integration. You could incorporate Skype into previous versions of Audio Hijack, but doing so was confusing. It's now much easier. Just drag in an Application block, configure it to record from Skype, drag in one or more Input Device blocks to record local audio sources, and have then all connect to a single Recorder block (and drag in an Output Device block to monitor the whole thing through your headphones).
The block options
If you're following along at home with the trial version you'll notice that when clicking on a block, that block's options are revealed. Each block can be turned on or off, which is helpful when you want to compare a sound with or without an inserted effect or you want to monitor the audio playing in an app but would like the freedom to easily switch off monitoring.
This On/Off switch is also key to monitoring what your workflow will actually record before you commit to the recording. Turning off the Recorder block acts as a kind of record-enable switch. When you switch this block off and click the Record button (which now turns white) you'll hear the results of your workflow but not record it. This allows you to make adjustments to your blocks (as they can be adjusted, added, and subtracted as you're monitoring or recording) before recording for real.
