Open the “File” menu and select the relevant song session. The method for doing so varies slightly according to which program you use, but you typically access works-in-progress from the “Recent” or “Recent Projects” sub-menu.

Click on the first vocal track. This highlights it, assigning all commands to this track specifically, rather than the mix as a whole.
Click the “Send” tab. On some programs, each audio channel has a “Send” tab. In other programs, there is a global send, which necessitates the need to select a track for sending. The “Send” tab on a digital audio workstation approximates the function of a patch bay on a hardware desk. It enables you to route audio from a recording channel to a group mixer channel.
Select “Bus 1” from the send options. In audio, a bus is a group-mixer channel. By sending multiple audio streams to one group-mixer channel, you effectively render all of that audio into one channel. This is called sub-mixing. It permits you to mix, add effects and edit multiple audio sources, such as all of your vocals, using one set of parameters.
Send the remaining vocal tracks to the same bus channel.
Click on “Bus 1” to highlight it.
Click “File” and select “Export As.” Select your preferred file type, such as WAVE audio or MP3. This exports all of the vocals as one audio file. You can use that file for an a capella version of your song or incorporate the vocals into a remix or new work.
