Audio Features
The notebook’s audio capabilities include the following features:
•
Digitized audio playback capability (up to 44kHz), which faithfully plays back
and reproduces all kinds of digitized sounds with a 16-bit Digital-to-Analog
Converter (DAC). The audio system works with a number of applications that
utilize the digital voice channel to deliver realistic human speech and sound
effects.
•
Digitized audio recording capability (up to 44kHz) allowing digitization and
recording of any kind of sound through the notebook’s built-in microphone or an
external source.
•
High quality sound, dynamically filtered for low noise digital recording and
playback. Input from the notebook’s built-in microphone uses Automatic Gain
Control (AGC) to compress sound input to adapt dynamically to different
recording conditions.
•
Audio compression which offers real-time compression and decompression of
digital audio. Compression turns large sound files into smaller files that can easily
be stored and transferred to a diskette or even sent over a network.
•
Built-in power amplifier and speaker, including volume control, and an audio out
port for connection to an external pair of stereo headphones or speakers.
1. When using the built-in microphone
•
For recording, make sure AGC is on and turn down the speaker
volume to avoid audio feedback.
•
For playback, with AGC off, turn down the speaker volume or
mute the microphone to avoid audio feedback.
2. When using an external microphone, make sure AGC is on.
