Inside Macintosh: Sound Manager
| Previous | Chapter contents | Chapter top | Section top | Next |
The Sound Input Manager uses sound input device drivers to allow applications to access sound input hardware in a device-independent way. A sound input device driver is a standard Macintosh device driver used to interface to an audio digitizer or other recording hardware. If you use the Sound Input Manager's high-level routines, the Sound Input Manager handles all communication with a sound input device driver for you. If, however, you need to use the Sound Input Manager's low-level routines, you must open a sound input device driver yourself. You might also need to get information about certain attributes of a sound input device. Sound input device drivers allow your application to query a device about such attributes.
