Line-In
Analog signals come in through the NEC Versa VXi’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.
Ambient sound effects create a sense of place or environment and include sounds such as
rain, heavy traffic, chirping birds. Specific sound effects accent or illustrate an action.
Examples of specific sound effects include footsteps, a crash, and a clock chime. There
are many sources of prerecorded sound effects available on the market, or, you can
record your own sounds.
Line-In accepts analog signals from external devices such as a tape deck, a stereo
CD-player, or a stereo tuner. The Line-In port has a mini-type connector. You may
need an adapter to connect your input device to the NEC Versa VXi through Line-In.
Note
Using Line-In does not disable the internal speakers.
CD-ROM Input
You can record music and sound effects from a CD (compact disc) and store them on
your hard disk. The audio signal from the CD-ROM drive connects directly to your
NEC Versa VXi. Simply follow the instructions in “Recording” to record sound from
your CD player.
Microphone
You can capture and record sounds through the internal microphone on the NEC Versa
VXi or through an external microphone that connects to the system through the
microphone port. You can record voice-overs for narration, reminders, or special
instructions.
See “Recording” earlier in this chapter, for details about recording sound with the
microphone.
