11.1.58 Pitch bend
This dialog allows you to change the pitch of a sound over time. Note that changing the pitch
using Pitch bend will affect its duration unless length preservation is activated.
Using an envelope you can 'draw' the curve you wish the pitch to follow. The pitch offset is
displayed along the vertical ruler of the envelope and the range the envelope effects can be
adjusted using the spin control. Positive pitch values produce sounds with a higher pitch and
of shorter length, negative values produce sounds with a lower pitch and of longer length.
If length preservation is activated, you can choose the algorithm that is used to perform the
pitch bend operation. Depending on the type of audio material you are processing, choose
the appropriate mode. For more information on the different modes, use the "What's This?"
tool. You can also adjust the quality used when processing the pitch bend. The quality setting
and the selected mode will affect the processing time for this effect.
This function could be used for creating the classic 'tape stop' effect, or for blending the
tempo/pitch of one track into another, for example.

11.1.59 Pitch correction
This dialog allows you to detect and change the pitch of a sound without affecting its length.
Amount of Shift - use these controls to find out the current pitch of the audio and if
desired, calculate the required shift to match a specific pitch.
Method - use these controls to adjust the method and quality you wish to use when
processing the pitch change. You can also choose how the length of the sound is
affected by the operation. By default this process will not change the length of the
sound.
This tool could be useful for fixing an off-key vocal note in a live recording, or tuning the pitch
of a kick drum sample to fit a particular song, for example.
