6-2 Using Multimedia
Audio
The NEC Versa provides entertainment-level sound quality through
stereo speakers. It handles MIDI files, digital audio files, and analog
audio sources. This means the NEC Versa recognizes .WAV, .MID, and
.AVI files. The system is 3D-positioning, Sound Blaster PRO™
compatible.
Recording
All information on a computer must be stored in digital form. Analog
audio signals from sources such as tape cassettes or music CDs must be
digitized before being recorded and stored on disk.
You can make recordings from two classes of audio input: line level and
microphone level. Line level accepts analog audio signals from
electronic sources such as tape cassettes, VCRs, and CD players through
the Line-In port. Microphone level inputs come through the microphone
port.
Note:
When using the built-in microphone,
make sure the speaker volume is turned down
before enabling the microphone or feedback may
occur.
To record, access Microsoft Sound Recorder located in Accessories
under the Multimedia group and select Sound Recorder. This
program provides the required software to record sound on your
NEC Versa notebook computer.
Line-In
Analog signals come in through the NEC Versa's Line-In port. The
analog signals are converted into digital bits and bytes (digitized)
through a converter known as an ADC (analog-to-digital converter). The
resulting digital sound bytes can be stored, edited, processed, and
transferred. You can record ambient sound effects, specific sound
effects, or music to enhance a presentation.
