OT - Creating surround sound track which moves between speakers

Hi All,



I have a test audio file which outputs a sound to a specific speaker (dolby 5.1) and then it moves around the room - I guess playing the same sound at different volumes in the various speakers.



I am doing a Harry Potter themed party and was thinking of doing this with my voice so I could pretend to be invisible - if you see what I mean. Anyo ne have any idea whether this is at all possible and whether there is an fr ee software that would do it (I am a Ubuntu user). After some Googling Aud acity seems to be able to handle various channels but all I can find is whe re people have a 5.1 surround file first and then mess with it.



Anyone any experience of this?



Also - any other suggestions for the themed party gratefully received :)



thanks



Lee.

If you google DAW software that should get you started. There are free and paid for applications. Bear in mind that mixing for Dolby digital formats may require licensed codecs - so even linux based solutions may not necessarily be free.

(you may also find some DVD mastering packages will do what you want)

Thanks very much John. I have tried a couple of DAWs as you suggested (Aud acity and Ardour) and I can't see anything about Dolby or 5.1 etc. I can s ee you can have as many tracks as you need but can't see how you would then map a track to a specific output channel (e.g. front left etc.). I guess I had anticipated something along the lines of either

  1. create project specifying you want to output as dolby 5.1 and then map t he tracks to the channels
  2. when you export the final project you would specify which track goes to which channel.

Sorry never used one of these before but any chance you could prod me in th e right direction?

Thanks again

Lee.

Hi All,

I have been doing some more searching and stumbled across this

Looks like I can do it from the command line assuming I can get the timings correct of the indivudal tracks.

Setup

Preferences -> Import/Export -> Use Custom Mix

Workflow.

  1. Create a multiple track audio project
  2. File -> Export Audio. Give it a filename, choose AC3 Files (FFmpeg) and a bitrate
  3. Map channels to where you want them in the output
  4. Done.
