High Speed Recording of your Vinyl (Optional)
Using the iTTUSB with Audacity software, you are able to quickly record
your 33 1/3 speed vinyl into the computer and use the software to
adjust the faster speed back to normal playback. This feature is useful
for recording multiple records. For example, you can record 10 minutes
of audio in as little as 7 minutes when recording at 45RPM with an
additional 10% increase using the pitch fader.
Saving three minutes isn’t a large saving for one record, but if you are
recording multiple LPs, you can record 4 hours of music in under 3
hours.
Instructions:
1. Record your 33 1/3 RPM vinyl at 45RPM by pressing the 45RPM
button on the top panel.
2. You will hear the audio recording at an unusual pitch due to its
high speed.
3. When you finish recording stop the recording.
4. Go to “Edit” and “Select All” (See Figure 4).
5. Go to “Effect” and then the “Change Speed” Menu.
6. Select from “45” to “33 1/3”
and your vinyl will be
adjusted to the correct speed
as shown in Figure
(optional) add additional
percentage change by
manually typing in the
change. (ie. To adjust
record at 45 RPM with +10%
on the turntable pitch fader,
select 45 to 33 1/3 and then
subtract an additional 10%
(-25.9% to -35.9% if you
record at 45 RPM with +10%
on the turntable pitch fader)
