8.4 : Rendering Tracks And Freezing Tracks
Rendering Tracks
Rendering a track is similar to exporting it in that it creates an audio le of the track contents. It is
specically designed to allow for fast bouncing of CPU intensive tracks to an audio le though, and this
fact is reected in the options available when rendering tracks.
To render a track:
• Select the track.
• Click the
render button in the properties panel.
• From the pop-up menu, choose whether the rendered track should be stored in the project di
-
rectory, or at an alternate location (typically you will want to choose the project directory as a
destination).
File: (Only available if you chose to render to a specic location.) Select a destination path and name
for the rendered audio le. Tracktion automatically selects a location inside your project folder and
names it appropriately based on the edit and the number of exports you have made.
Sample rate: Select a sample rate for the rendered le. This should typically be matched to the sample
rate you are using for the rest of the edit, or at least as a direct factor of it.
Sample size: You can select the bit depth of the rendered audio. Generally it is best to leave this at 32-
bit, but 16-bits can be used to reduce the le size and load on the hard-drive when the le is streamed
during playback.
Format: You can choose between WAV and AIFF formats. Typically WAV is the better choice as BWAV
time stamps will be written to the le, making it easier to import and match the start time in other proj-
ects.
Bypass lters: When this option is selected, the resultant audio le will not have been processed by
any lters on the track. Generally this option can be more exibly replaced by simply disabling lters
that you do not wish to have active on the rendered audio.
Replace rendered tracks: The tracks that were rendered will be replaced by the rendered results
when this button is clicked.
Add rendered tracks: When this button is clicked, the rendered les will be added to the edit as new
tracks. This allows you to mute out the original track, and use the rendered track to save computer
resources. If you decide you want to make alterations to the source material, you can unmute the rst
track, edit it, and re-render it when ready. BY placing both source and rendered track in a folder, you
can use this trick to extend your computer’s resources without needing to have extra tracks cluttering
up your edit.
