Frequently Asked Questions about Audio Post-Production
Which files do you need from us?
A reference video with timecode and the audio tracks from the edit, ideally as AAF or OMF. Feel free to send music and graphics with their own sounds separately.
Do you deliver an M&E track for international versions?
Yes. On request we create an M&E track (music and effects) without dialogue, the basis for any later dubbing.
Which loudness standard do you mix to?
For broadcast to EBU R128 (−23 LUFS), and for cinema, streaming and online to the specifications of the respective broadcasters and platforms.
Can we attend the mix?
Yes, in person in our Munich control room or remotely via SessionLink and Source-Connect, so you can discuss changes live and approve them straight away.
