Accuracy Sets the processing resources allocated
to audio quality (Sound) or timing (Rhythm).
Set the slider toward Sound for better audio
quality and fewer audio artifacts. Set the slider
toward Rhythm for a more consistent tempo.
Reference Pitch Activates a sine wave-based
pitch generator that you can use as an audible
reference when pitch-shifting audio material.
Note Adjusts the frequency of the reference tone
in semitones (half steps).
Detune Provides finer adjustment of the fre-
quency of the reference tone in cents (100ths of
a semitone).
Gain Adjusts the volume of the reference tone
in dB.
To use the Reference Pitch:
1
Select the audio material you want to use as a
pitch reference. Click the preview button to be-
gin playback of the selected audio.
2
Click the Reference Pitch button to activate
the reference sine wave tone.
3
Adjust the Note and Detune settings to match
the reference tone to the pitch of the audio play-
back. Adjust the Gain setting to change the rel-
ative volume of the reference tone. It may also
be helpful to toggle the Reference Pitch on and
off to compare pitch.
4
Select the audio material to be pitch shifted.
5
Adjust the Coarse and Fine Pitch Shift con-
trols to match the pitch of the audio playback to
the reference pitch.
6
Click Process to apply pitch shift to the selec-
tion.
Time Shift
Time Shift provides high quality time compres-
sion and expansion (TCE) algorithms and for-
mant correct pitch-shifting. Time Shift is ideal
for music production, sound design, and post-
production applications. Use it to manipulate
audio loops for tempo matching or to transpose
vocal tracks using formant correct pitch shift-
ing. You can also use it in audio post-production
for pull up and pull down conversions as well as
for adjusting audio to specific time or SMPTE
durations for synchronization purposes.
Time Shift Displays and Controls
The interface for Time Shift is organized in four
parts: Audio, Time, Formant or Transient, and
Pitch.
