GiO by APOGEE – User’s Guide
Can I record my session on the startup hard
drive?
It’s an accepted “best practice” of most audio software providers
that audio les should be recorded on a hard drive other than the
Mac’s Startup drive (i.e. the drive on which the operating system is
installed). You can probably get away with recording a few tracks to
your computer’s Startup disk, but for the best performance of your
GiO recording system, record onto a separate ATA/IDE, SATA, or
FireWire drive whose spindle speed is at least 7200 RPM.
How do I set the input control of my powered
speakers?
Most powered speakers offer an input volume control, often labelled
as input sensitivity. Rather than describe an overly complicated
method for setting this control, the easiest way to determine the right
setting is to note where you generally set GiO’s output level. If you
nd yourself rarely turning the output past a very low output level
(say, -35 dB), decrease the input sensitivity on the speaker. If, on
the other hand, you nd yourself setting GiO for full output and the
speakers aren’t loud enough, increase the input sensitivity. Ideally,
GiO’s output should be at 0 dB when you’re listening at your absolute
maximum desired volume.
I/O buer continued
Keep in mind that as tracks and plug-ins are added to a software
session, processor requirements increase. Thus, the buffer setting
that works during the early stages of a session might result in
processor overruns during later stages.
The best strategy is to set the buffer to a lower setting during
recording and accept certain limitations on plug-in usage, and then
raise the buffer during mixing to utilize the computer’s full processor
power when latency isn’t an issue.
With the processing power of today’s Macs, you may nd that
adjustment of the buffer isn’t necessary, and you can leave it at
a setting for low latency and still access a sufcient amount of
processing power when adding tracks and plug-ins. If you do
encounter clicks, pops or software errors, don’t hesitate to
experiment with the buffer setting.
Please consult the section on Working with GarageBand, Logic and
Mainstage to determine how to se the I/O buffer setting is found in
your audio application.
What sample rate should I record at?
GiO offers a choice of two sample rates, 44.1kHz or 48kHz. So,
what’s the best sample rate to record your project at? It’s a good idea
to avoid unnecessary sample rate conversion stages, so the answer
is determined by the sample rate of media on which you plan to
distribute your recording. If the nal distribution media is CD, record
at 44.1kHz. If the media is video or TV, most often 48 kHz is the best
choice. If you’re part of a larger production chain, and aren’t sure,
ask the person who’s responsible for assembling the nal product -
they’ll undoubtedly appreciate the forethought.
