- WELCOME TO SOUND MANAGER 3.0
-
- The Sound Manager 3.0 software consists of
-
- - the Sound Manager system software extension
- - a new version of the Sound Control Panel
- - a technical note explaining some of the new features
-
- Available since the introduction of the Macintosh II in 1987, the Sound Manager
- is Apple's digital audio software solution that allows any application to play
- and record sounds using the built-in sound hardware found on Macintosh
- computers.
-
- Sound Manager 3.0 is the latest version of this software. It adds support for
- 16-bit CD-quality audio, redirection of sound to third-party hardware cards,
- and plug-in audio compression/decompression software (codecs). It is
- completely backwards compatible with previous versions of the Sound Manager.
-
-
- INSTALLING SOUND MANAGER 3.0
-
- To install Sound Manager 3.0:
-
- 1. If you received a floppy disk labeled "Sound Manager", insert it into your
- computer and open it. If you downloaded Sound Manager 3.0 electronically, make
- sure the Sound Manager files you downloaded are visible.
- 2. Drag the Sound Manager and Sound control panel icons from the Sound Manager
- disk onto your System Folder icon (not into the open folder).
- 3. Click OK in the dialog box that appears.
- 4. Restart your Macintosh.

- NEW FEATURES OF SOUND MANAGER 3.0
-
- • Support for 16-bit audio samples
- Previous versions of the Sound Manager could only support stereo 8-bit audio
- samples with sample rates up to 22 kHz. Sound Manager 3.0 removes this
- limitation by allowing stereo 16-bit audio samples with sample rates up to 65
- kHz, providing CD-quality audio in QuickTime movies and other audio
- applications. Sound Manager 3.0 will also automatically convert 16-bit sounds
- into 8-bit sounds on Apple personal computers that do not have 16-bit audio
- hardware.
-
- • Support for third-party audio hardware
- Third-party sound cards can be installed in your Macintosh to allow playback
- and recording of CD-quality audio. Sound Manager 3.0 makes this possible by
- providing a driver mechanism and a new Sound control panel that allows the user
- to redirect sound to any available audio device. Audio card developers can
- license the Sound Manager 3.0 extension and bundle it for distribution with
- their product.
-
- •Support for plug-in audio codecs
- The Sound Manager previously supported only MACE audio compression at ratios of
- 3:1 and 6:1. Sound Manager 3.0 goes beyond MACE to support any compressed audio
- format with the use of plug-in audio compression/decompression software
- (codecs). These are simply extension files placed in the System Folder that the
- Sound Manager recognizes and uses when it needs to play a compressed sound. In
- this way, applications can play compressed sounds seamlessly without being
- aware of the compressed format.
-
- • Better performance and quality
- Sound Manager 3.0 is much faster --in many cases 2-3 times more efficient than
- previous versions. This means that your application can do more while sound is
- playing. Sound Manager 3.0 is also more robust: many bugs have been fixed and a
- number of commonly requested features have been added. Refer to the Technical
- Note for more information.
