Audio processing and functions
Audio processing
• If the intervals you add make up a standard chord, this chord is displayed to the
right.
Note, however, that to include the base pitch (the original, untransposed sound) in
the processed result, you need to click the base key in the keyboard display as
well, so that it is displayed in blue.
Listen Key/Chord button
Clicking this button plays a test tone pitched according to the activated interval key on
the keyboard display. If “Multi Shift” is activated, this button is called “Listen Chord”
and plays all activated intervals as a chord.
Pitch Shift Base
This allows you to set the root note (the red key in the keyboard display). It has nothing
to do with the actual pitch, but is an aid for setting up intervals and chords.
Algorithm Settings
This is where you can make settings for the MPEX 4 algorithm. For a description of the
available presets, see
“About time stretch and pitch shift algorithms” on page 322.
For each quality setting you can choose between the regular setting and a setting
where the formants are preserved. If you are processing vocal material, select the
Preserve Formant setting in order to preserve the vocal characteristics of the pitch-
shifted audio and to avoid a “chipmunk voice” effect.
Time Correction
When this is activated, the pitch shift process will not affect the length of the audio.
When this is deactivated, raising the pitch will shorten the audio section and vice
versa, much like changing the playback speed on a tape recorder.
Using envelope based Pitch Shift
When the “Envelope” tab is selected, you can specify an envelope curve on which the
pitch shift will be based. This allows you to create pitchbend effects, pitch-shift
different sections of the audio by different amounts, etc.
