How to export just one section of a mix

Select on the timeline

Drag across the waveform in Montaje (session). The selection starts on one lane and defines a range shared by all of them. To take out, for example, the transition between 24 and 32 s, select those eight seconds. Use Escuchar selección (play selection) to hear the sum of the tracks that overlap in that range.

Check which tracks are in Solo or muted. If you want a copy of a single file with its own start and end, single trim lets you work directly on its waveform.

Set the start and the end

Press Usar selección al exportar (use selection for export) on the selection bar. You can also open Opciones → Exportar mezcla… (options → export mix) and untick Toda la sesión (whole session). In the panel you can correct the Inicio (start) and Final (end) in seconds, or use the cursor position. Confirm that there is audible audio within the range.

Save the section

Check the levels and press Exportar mezcla WAV (export WAV mix). The file starts at the given start time and lasts the difference between the two times. In the example, 32 minus 24 gives eight seconds. If you are exporting to rehearse a blend, leave enough audio before and after the change to hear the context. To come back to the same range another day, save it as a region in the project.
