Effect Menu - Brookstone iConvert USB Turntable User Manual

effecT MenU

The items in this menu only work when you have audio selected . Audacity does
not have any real-time effects; you must select the audio, apply the effect and
then listen to the results .
Most effects have a Preview button . Clicking on this button plays up to three
seconds of audio, allowing you to hear what it will sound like after the effect
is applied . This is useful for fine-tuning the effect parameters .
Repeat last effect - Selecting this command is a shortcut to applying the most
recent effect with the same settings . This is a convenient way to quickly apply
the same effect to many different parts of a file .
amplify - Changes the volume of the selected audio . If you click the "Allow clipping"
check-box, it will let you amplify so much that the audio ends up beyond the range
of the waveform, and is clipped (distorted) . The default value when you open the
effect is to amplify so that the loudest part of the selection is as loud as possible
without distortion .
bass boost - Enhances the bass frequencies in the audio .
change Pitch - Changes the pitch/frequency of the selected audio without changing
the tempo . When you open the dialog, the starting frequency is set to Audacity's best
guess as to the frequency of the selection . This works well for recordings of singing
or musical instruments without background noise . You can specify the pitch change
in one of four different ways: musical note, semitones, frequency or percent change .
