Pitch Bend Dialog

• To open the Pitch Bend dialog, select the Process tab in the Audio Editor, and click Pitch Bend in the Time & Pitch section.

The following options are available at the top of the dialog:

• Undo the Last Operation

• Redo the Last Undone Operation

• Deselect the Envelope Points

• Delete the Selected Envelope Points

• Reset the Selected Envelope Points

• Reset the Whole Envelope

• Flip the Envelope Around the Horizontal Axis

• Reverse the Envelope Time Sequence

• Toggle the Envelope Smoothing

The following options are available at the bottom of the dialog:

Preserve Duration

If this option is activated, a time stretching process is applied to compensate for the change of duration caused by the pitch modifications.

Method pop-up menu

Auto/Preview: Automatically selects the best time/frequency trade-off for real-time/preview performance. This is the fastest setting, but might not provide optimal results in all cases.

Time Localization ++ (Instruments, Voices): Selects full time localization. This is a good setting for single instruments and solo voices.

Time Localization +: Selects the time/frequency localization with the emphasis on time localization. If the previous mode produces echo artifacts, try this option.

Average Time/Frequency Localization: Sets the time/frequency localization halfway between the time and frequency domains. It is the best setting for all general purpose signals.

Frequency Localization +: Selects the time/frequency localization with the emphasis on frequency localization. This is a good setting for classical music.

Frequency Localization ++ (Complex Mixes): Selects the highest possible frequency localization. This setting might not work well on material with many sharp attack transients, but it can produce good results with less transient/percussive material.

Transcribe Mode (for Large Changes): This uses a content aware algorithm to time stretch and pitch shift music by up to 4 times the original length without losing information critical to transcription, such as attack transients.

Varies with Envelope

If this option is activated, time stretching is continuously applied, but varies depending on the pitch changes. If this option is deactivated, time stretching is applied equally to all audio parts.

In both cases, the global audio duration is preserved. The option is activated by default because this gives a more natural result. However, this affects the quality of the audio.

Quality pop-up menu

The High Quality and Best (Slow) modes provide high quality time stretching, but the processing takes longer. For most uses, the Standard Quality mode is sufficient.

Range (Semitones)

Specifies the maximum range in semitones for the pitch change. When you change this value, this is indicated in the vertical ruler.
