Is this method useful for purely separating a stereo audio stream into a 5.1 audio stream? I don't necessarily want to put an effect on the audio, just "convert" to 5.1 audio. Your post and link might have some really good effects. That level of processing power has only been available to us in recent years. strange ! Because you point to a method that was developed in the 70's > Ambisonics !Īgain, I'm not so sure what you mean by "Ambisonics", since I haven't taken a good look at it, yet (because it needs special recorded material to work with), but, the technique I've showed could not have done much help back in the seventies, since it requires a processors to convolve, in real time, several channels, with high accuracy. In this light I found your remark about the "outdating" rather insulting and. Without those two factors, I'm affraid the results might not be satisfying. Also, the room should be acoustically dead. At least that's what I've heard.Īlso, the technique I showed really needs a minimum of 4 surround speakers to sound good. It can't just work with any stereo recording. Yes, I heard something about Ambisonics, but as far as I know, Ambisonics needs special encoded material to work with. Where exactly did you see me mention the word "Ambisonics" ?. You can then Load the x.mux file into Besweet and convert to a 5.1 AC3 Once you have that typed in, got to save and save it as "X.mux" Open Windows Notepad and type in the paths of your Mono Tracks-Example You Should now have 6 Mono Tracks that can be Muxed to a 5.1 Track in The Latest Version of Besweet. After this you simply use the same method used to produce the Front Left and Front Right Channels (Explained Above) You can then adjust the levels using the amplitude function to decide how loud or low you want the surrounds in the mix. This also makes it much easier to single out any certain sounds you may want to be portrayed in your mix. This not only removes the center channel but it also gives you a stereo reproduction in the sound which isn't possible with Cool Edit's "Vocal Cut" Preset. Surround Left, Surround Right For Adobe Audition (Recommended) Save your Left Surround Channel as "X-SL" then do the same for the Right Surround as "X-SR" This Mixes down your surround track to A mono track. Once you have completed that, select the Surround Track you want to mix down first, click the solo button then go to Edit>Mix Down To File>All Waves Mono. The Surround left would have a Time Offset of 0:00.000 and the Right would have a Time Offset of 0:00.010. I usually right click the track thats panned to the right, go to wave block properties and change the time offset to 0:00.010 to give a little delay to the Surround tracks. Once in the Multitrack session, pan one track 100% to the left and the other to the right. Insert The finished Track into the Multitrack 2 Times. Open your stereo file, Go to Effects>Amplitude>Channel Mixer then in the presets go to Vocal Cut, Click ok. Surround Left, Surround Right For Cool Edit Pro The LFE Channel usually Depends on how much bass the original song has, if the song has strong bass and the waveform looks similiar to the song you need to Decrease the volume on the LFE track or else your final 5.1 track will be distored and overly bass heavy. Open your stereo file, go to Effects>Filters>FFT Filter, Scroll down on the Presets list to "Only The Subwoofer", click ok, then once again go to Convert Sample Type and have 50% for left and 50% for right. Then you have your finished center channel with any tweaking that you think is neccessary for the sound you want. Then hit F11 to convert the sample type to 16-Bit Mono, using %0 of the left channel and %100 of the right. and use the "Center on the Right Preset". After that, go to Effects>Amplitude>Pan/Expand. This is the setting I use for The Center Channel ()Ĭlick ok. Open your Stereo file, and go to Effects, Filters, Center Channel Extractor Save your track as "X-C"Ĭenter Channel For Adobe Audition (Recommended) Now Slide the Amplitude>Amplify to Increase or Decrease the levels. Make sure it is set in 10 Bands and all levels are at 0db. Open your Stereo file, and go to Effects, Filters, then Graphic Equalizer. Complete the process again and do the same For Front Right, except have the Left Mix at 0% and the right at 100% Save your tracks as "X-FL" and "X-FR" Where it says Channels, check Mono, then for the Left Mix put 100% and For the Right Mix put 0%, Click ok and now you have your Front Left Channel. Open up your stereo sound file into cool edit pro or Adobe Audtion go to convert sample type or press F11 to get there. Software Needed- Cool Edit Pro or Adobe Audtion
