Increasing New Audio Length


I am trying to create a binaural beat of about 2 hours. I select Tracks>Add New>Audio Track x2; to make to audio tracks for the left and right headphone; then I go to Generate>Tone to create my binaural beat. It works great but the problem is I cant figure out a way to make them longer than the default 25 seconds? The entire timeline itself is only 37 seconds too.

Just wondering how I can make my tone and timeline stretch to 2hours?

Start with Generate > Silence: 120 minutes.
That will give you a two-hour silent guide track and then you can add other tracks underneath that as you go.


The default for “Generate > Tone” is 30 seconds.

To generate a longer tone, type in a longer duration in the “Duration” control:
