RECORDING ALBUMS WITH AUDACITY
1. SAVING A PROJECT
•
Audacity writes all the changed and
recorded audio to a directory called
Projectname_data
which is located where you saved the
project file itself
•
Thus, select Save project as from your
Audacity File tab and choose a location and
filename for your project
•
Please note that when you startup Audacity
fresh, only the “Save As...” menu option
is available
2. HOW TO RECORD
•
Set your USB turntable up to play the song
or album you want to record
•
Click on the red Record button to begin
recording.
•
Lower tone arm on USB turntable onto the
album and track you want to record.
•
Click on the blue Pause button to pause the
recording.
•
Press it again to continue.
•
Click on the yellow Stop button to stop
recording.
THATS IT!
You can now play around with your recording
and explore the editing capabilities of Audacity.
Remember that you can use the Undo function
almost without limits while the project is open.
NOTE: CDs cannot be burned directly from the
Audacity application. Other CD burning
applications need to be used for this.
TECHNICAL INFORMATION
Screw in a grounding connection when using a
turntable.
If a CD player with a very high output is used,
the input recording level can exceed 1V rms,
this will result with slight digital noise and
distortion and the LED will turn from green to
red. To find the correct position of the line
input gain, turn the knob counterclockwise
until the LED returns to green. You are now
ready to start recording.
If the output of the USBH100 MKII is
connected to a mains earthed mixer, an earth
loop can be generated. In cases like this a
ground loop isolator should be used.
