The shooting in this case is being recorded on video.
Video is based on TIME (seconds) not “frames per second” like film.
So the audio does not need to be recorded in “X Frames per second”.
On the timeline, exactly 30 seconds of audio will play in exactly 30 seconds, regardless of the number of video frames per second.
Simply choose the best available audio (say, 48 kHz 16 bit) and record the tracks.
A FILM camera cranking at 24 fps, but transferred to video at 30 fps needs the audio to be “adjusted”.
Video to Video needs no such “adjustment”.
A PAL 25 fps converted to NTSC 30 fps (or so) will play at the same speed as its original footage. No audio adjustment needed.
