Appendix C. Additional Information for Mwave DSP Feature

Note:
In some countries, the Mwave
telephony functions are available
only after the DAA/Telephony Kit
option is installed.

This appendix provides detailed information about the ThinkPad
Mwave DSP Features.

Audio Information

This section provides information about the ThinkPad audio features.

Sound

The Mwave DSP features provide support for Windows Version 3.11
audio applications that comply with the Windows MultiMedia
Extensions (MME) for audio, for example, Windows Sound Recorder
and Windows Media Player that are shipped with Windows Version
3.11.

In general, recording audio music and speech at higher quality
requires more disk storage. The following table shows some typical
