Pitch Shifting Dialog

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

This dialog is also available as a monopass plug-in in the Batch Processor window.

Semitones

Allows you to specify the amount of pitch change in semitones.

Cents

Allows you to specify the amount of pitch change in cents.

Find Current Pitch of Audio Selection

Analyzes the pitch of the selected audio and displays it below this button.

According to the current pitch, compute the required shift to match the key hereafter

Click to adjust Amount of Shift parameters automatically, based on the detected pitch and the pitch specified in the value field below this button.

Pitch field

Specifies the resulting pitch.

Length Preservation

Specifies how the length of the selection is affected by the operation:

• A setting of 100 means that the length of the audio remains unchanged.

• A setting of 0 means that the program behaves like a tape recorder, when the speed of its tape is changed. For example, if you raise the pitch by one octave, the audio is half as long.

• Intermediate values give results in between these two extremes.

For large transposition values, the lower this setting, the better the quality of the effect.

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.

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.

Correct Formants

If this option is activated, changing the pitch of vocal material gives a more realistic result. When processing non-vocal material, leave this option deactivated, because it uses a slightly slower processing algorithm.

Note

This algorithm might cause a noticeable increase in signal level.

Modulate Formants Correction

If this option is activated, the formant correction is modulated over time.

Note

If the envelope is not used and the formant correction is activated, a 100 % correction is performed.
