Hi @Acirco,
Welcome to the forums!
Shotgun is heavily customizable and has been used creatively for many things that fall way outside it’s core competencies of VFX, Animation and games. This thread has some extreme examples.
Shotgun doesn’t have any out of the box integrations with any audio packages or Google Sheets. We do however have very powerful APIs (Python and REST) that could be leveraged for your technical team to write integrations and automations.
This being said, Shotgun is geared primarily towards a visual workflow. If you wanted to leverage any review and approval workflows for your audio material, you’d probably have to wrap those in video formats with a blank/black video feed which may not be optimal.
I’m pretty positive the rest of the Shotgun toolset like tasks and scheduling would surely be useable out of the box by your team.
I’ve assumed that you’ve already tried Shotgun but if not, feel free to sign up for a free trial.
