Audio processing and functions
Applying plug-ins (Cubase only)
Original Length section
This section contains information and settings regarding the audio selected for
processing:
Resulting Length section
These settings are used if you want to stretch the audio to fit within a specific time
span or tempo. The values will change automatically if you adjust the Time Stretch
Ratio (see below).
Seconds Range section
These settings allow you to set the desired range for the time stretch.
Time Stretch Ratio section
The Time Stretch Ratio determines the amount of time stretch as a percentage of the
original length. If you use the settings in the Resulting Length section to specify the
amount of time stretch, this value will change automatically.
Algorithm section
In this section you can select a time stretch algorithm. The pop-up menu contains
various presets sorted into category submenus based on the underlying technology:
élastique, MPEX, and Standard. For a description of the available presets, see
“About
time stretch and pitch shift algorithms” on page 322.
Applying plug-ins (Cubase only)
You can add plug-in effects in realtime during playback (see the chapter “Audio
effects” on page 227). However, sometimes it is useful to “permanently” apply effects
to one or several selected events. In Cubase, this is done in the following way:
1. Make a selection in the Project window, the Pool or an editor.
Effects are applied according to the same rules as Processing (see “Common
settings and features” on page 303).
2. Select “Plug-ins” from the Audio menu.
Option Description
Length in Samples The length of the selected audio, in samples.
Length in Seconds The length of the selected audio, in seconds.
Tempo in BPM If you are processing music, and know the actual tempo of the audio,
you can enter it here as beats per minute. This makes it possible to
time-stretch the audio to another tempo, without having to compute
the actual time stretch amount.
Option Description
Samples The desired length in samples.
Seconds The desired length in seconds.
BPM The desired tempo (beats per minute). For this to work, you have to
know the actual tempo of the audio, and specify this (along with time
signature and length in bars) in the Original Length section to the left.
Option Description
Range Allows you to specify the desired length as a range between two time
positions.
Use Locators Clicking the diamond-shaped button below the Range fields sets the
Range values to the left and right Locator positions, respectively.
