Film & TV Audio Post Production FAQ

Some of our Frequently Asked Questions & Answers:

You can find out more detaled information at our specific FAQ pages.


Q: I need to and a Music & Effects (M&E) track to my show, what is that?
A: An M&E track contains all the same audio excepting dialogue that exists in a full stereo mix. When you watch an M&E track you will see the lips moving when characters speak but no dialogue coming out. This is done for the purpose of dubbing the movie into other languages. The new language is added to the overall mix and the file is then re-exported to contain the new dialogue track.


Q: My M&E tracks were rejected for missing effects, what do I do?
A: This means that some of the sound effects that were present in the original mix or not in the M&E mix. This includes everything from footsteps, hand taps, doors opening and closing, etc. Often a Foley studio will be needed to add effects that cannot be added from a stereo mix track. We have experience at adding missing effects to M&E tracks even without any source material.


I need to deliver a 5.1 mix with my movie, how is this done?
There are many types of audio configuration that a distributor, sales agent, or network may require, aside from Stereo mix and stereo Music an effects track (described above) the next most likely audio set you will need is a 5.1 mix, this is for surrounde sound home audio systems. 5.1
It must contain 6 separate tracks with 2 sets of stereo pairs, and 2 mono tracks.
The first 2 tracks are called 5.1 Left, and 5.1 Right, these correspond to the 2 speakers in a 5.1 mix that would be in the front on the left and right sides. in a "true" 5.1 mix these tracks would have all music and effects, but no dialogue, the left/right tracks are a stero pair, and must be in stereo for the mix to be correct. The third track is a mono dialogue only track called "Center" which is of course the center front speaker in a 5.1 mix. The forth track is also mono and is called LFE, (Low Frequency Effects) and contains the bass sounds the LFE speaker is essentially a sub-woofer, and is usually in front and down below the other speakers. The Final 2 tracks (numbers 5&6) are called Left Surround / Right Surround, these are the speakers in the back of the room giving the "surround" effect. They are a stereo pair and often contain the same tracks as the Left / Right pair at a lower volume level. All 6 tracks must be in sync.
