Mine is being edited in 5.1 surround sound and I have my 5.1 system hooked up to my computer so I can test each individual speaker as well. And regarding the music selection, I've got it down flat. I have about 20-30 GB of Instrumental music to chose from. And how am I putting it in? Mainly I'll be adding music to the scenes that lack it and I'll also be adding it to scenes where the music's volume is low and going through each audio channel and playing with the Frequency of each channel then putting 6 new audio channels through and adjusting the frequency of the music for each speaker again to give the best experience possible. (Subtle instruments in the back, drums from the base, strings from the front and vocal/choir from the center speaker). Do you guys know how to access the Equalizer for the Audio Frequencies of each individual audio channel using Vegas?
