User Interface

Other than support for hardware volume control, there is no direct user interface for sounds, apart from the Sound, Recording, and Alarm preferences panels, and the volume control in the Extras Drawer. The system does include three new user interface objects that support sound input: sound stationery, the *soundRecorder slip, and *protoRecorderView.

Sound stationery is a new type of Notepad stationery that allows users to record and play back sounds. Users can tap the New button and choose the Recording item to create a new recording sheet, as shown in Figure 7-1. The recording sheet contains controls the user can tap to record and play sounds. In addition, it contains lined "paper" like a regular note, on which the user can write notes.

There's no developer interface to the sound stationery.

The *soundRecorder slip is a root view slip (Figure 7-2) that allows you to easily include sound recording and playback in any application. This slip incorporates all the code necessary to record and playback sounds. For information on how to use this slip in your applications, see "Using the Built-in Sound Recorder Slip".
