Setting Tempo Parameters in the “Time and Pitch Machine”
The Tempo section is divided into two columns: The Original column displays the current
values of the selected area in the audio file, and the Destination column is where you set
the desired tempo parameters.
• Tempo Change: Determines the tempo alteration, displayed as a percentage (no original
value is shown).
• Tempo: Displays the tempo in bpm (beats per minute). Make sure to set the right
length in bars, or the correct original tempo will not be shown on the left.
• Length in Samples: Displays the length of the selected area in samples.
• Length in SMPTE: Displays the length of the selected area in SMPTE time format.
• Length in Bars: Displays the length of the selected area in musical values (bars, beats,
divisions, and ticks). If you have already adjusted the project tempo to match the region
that you’re about to edit, the original value will automatically be set correctly. If not,
you need to manually enter the original length here.
Setting Pitch Parameters in the “Time and Pitch Machine”
The pitch parameters determine the amount of transposition in cents, and also the
strength of harmonic correction, if used.
• Transposition: Transposition of the sound material in 1/100 semitone units (cents). A
value of 100 results in an upward transposition by one semitone. A value of −1200
results in the audio material being transposed down an octave.
