I like to create video with spatial audio (4 channel) from Vegas 22.
I read on youtube page that AAC is supported when uploading:
How to create such files from Vegas?
I cannot change AAC render templates, which is only mono/stereo.
Does the audio render have to be AAC?
In Vegas Pro 22, you could set Project Properties (audio tab) to '5.1 surround', disable the centre channel in the panner in the audio track's header (thereby leaving 4 channels LF, RF, LR and RR)) and then use one of the few audio render formats that support 5.1 those being Sony Wave64, Wave (Microsoft) and Sony AVC/MVC (which actually does do AAC 5.1).
Other render formats offer 4 channel audio but are rejected on my laptop possibly because of its basic sound card.
I think video with 5.1 channel surround audio won't be accepted as ambisonic spatial format in youtube.
From the following YT video from a couple of years ago, this may/might be a good overview of how to achieve ambionic audio for YT and other social media:
The presenter recommends Reaper for audio processing but does note that an ambionic microphone is needed to record ambionic sound. One of the YT comments was that they got it to work in DaVinci Resolve/Fairlight but no info as to whether that was with the free or paid Studio version.
Of course, anyone on the forum who has actually used ambionic audio (whether in Vegas Pro or not) will be in a far better position to advise particularly as to whether or not a specific ambionic microphone is needed for acquisition.
Yes, i have a Zoom H2N, which can record in spatial format. I dont want to make any editing besides trimming start/end. I hope i can stay in Vegas.
