5.1 Audio....how to do it?
I've got a 2mins short film project. Plan to do the audio completely at post (ADR, Foley, SFX…).
Now, I’ve got an idea. Because every piece of audio is done in post, so that would be possible for me to put different audio in 6 different tracks to make it 5.1. However, it seems all my audio program and video program haven’t got this function. I remember I saw something online is call audio authorization. Is that the function to do 5.1? is there any program to do that or support that? Any web site or article I can read about? |
If you use Premiere Pro and have the Surcode plug-in, create a project with a 5.1 master sound track and use the audio mixer to create your soundtrack. Should be similar with Vegas.

Thx for your answer.....so is the edit program will do the job.....
I am using premiere pro at the moment....but havn't got that plug-in, I will go look for it. How about Final Cut studio? I have access to final cut pro and sound track pro. will they support 5.1? |

For the LFE channel, if one of your five main channels contains all the bass intensive sound, just drag that onto the LFE dropzone in compressor. Compressor will then use filters to extract just the low frequencies. Otherwise, you can or course create an AIFF file for the LFE channel manually and use that file. I am not endorsing this as a great way to create 5.1 surround sound, but it works. A step up would be Logic Pro, which - to my knowledge - is currently the only Apple software that allows panning of sound in space for 5.1 mixes. - Martin |

Vegas has had surround panning for ages. I take it for granted.
Anyway, the way it works is that you take all your audio tracks, and keyframe the positions in the audio stage. The editor then collates all the tracks and generates the six channels for you. In other words, one track does not have to correspond to one channel. The LFE channel is special, though; it is generated by taking the other five channels and running them through a lowpass filter, so you generally do not explicitly send information to the LFE channel, though it is an option (in Vegas, at least). |
