(Tips and Hints)
Record Sample Rate
When deciding at what rate to record a sample, keep in mind
that the higher the sampling rate, the higher the sound quality
but the more memory used. We recommend that you
experiment to find out how the quality differs with lower
sampling rates for both voice and music recording. Notice
that the sound quality of voice recordings don't improve
much above a record rate of about 7,000 Hz while music
sound quality drops dramatically when recorded at the lower
rates.
In general, voice recordings require lower sample rates
(around 7,000) while music (especially from CD's) require
higher sample rates (we recommend the maximum, 37,000).
Also keep in mind that you need to use the same record rate
when pasting a sound into an existing file.
Stereo or Mono?
When deciding whether to record a file in stereo or mono,
consider these points:
o
Do you have a stereo signal?
If you have only a mono signal, there is no reason to
record in stereo; mono recordings can play back
through both speakers.
o
If
you
want control of both left and right channel
outputs of a mono recording, you can:
Fun Stuff
1)
Record the input in mono.
2) Paste it to a blank stereo file.
3) Edit the left and right channel separately. (See
"Effect Channel" p.4l.)
This allows you to record and play back at a higher
sampling rate than if you make the recording in
stereo. (See also, "Traveling Sound" p. 56.)
You've probably had a chance to mess around with the
Audio Animator software by the time you read this; we have,
too. Here are a few things we've tried at Applied ...
