In this video, John Escobar, a professor in the Music Production and Engineering department for Berklee College of Music, demonstrates how to set up and calibrate audio for recording ambisonics on video. You’ll want to make sure that all four channels coming out of your mic are going into a system that can be properly calibrated: Ideally, you’ll want the calibration to be within one tenth of a dB. You’ll also want to link all channels on your recorder, so with the turn of one gainstage knob, you can control the levels of all four channel preamps. It’s also important to measure the delay times between spot microphones and ambisonic sound sources. Additionally, be mindful of mic placement and the acoustic space you’re recording in. Setting up at Boston Symphony Hall, Escobar uses four ambisonic mics to truly capture the feel of the space. You’ll also want to make sure you’re able to monitor sound while capturing ambisonic recordings.

The suggestion to measure the delay between spot microphones and the ambisonic was very helpful, thank you.

Wowwww

[@simontait9638]

Was there is mistake in the description of mapping of channels to capsules? I got Channel 2 mapped to Left Right Down - should this be Left Front Down?

[@WerIstWieJesus]

Is there no AI tool that can analyse the tracks and calculate the relationships and delays by the similarity of the sounds on the channel?

[@Rhythmattica]

This shows if cheap versions of Ambersonic mics are released onto the market, , you better hope the capsules aren't different outputting any more than 1db in difference.....
Btw.. The first thing to calibrate the Pre's, Id at least try first setting the mic pres at zero, gang them , and see if at least they all match at -12db when gaining up....... if its a HQ recorder, with great pres, could save you time setting up.. Of course , YMMV depending on the gear, But, possibly save time,.
