How to Record Backup Audio Track for your Video
The good people from cheesycam recently published a very useful guide showing how you can create a backup sound channel using a simple cable and a field sound recorder.
This video is all around having redundant backup for an interview style sound recording. for this demo the Zoom H6 which offer a backup recording option (its of course not the only recording unit which offer this feature. The idea here is that if you record a person in an interview and from some reason his sound gets too loud, you can record two tracks – one will be in normal volume while the other in a reduced volume so you will not get a distorted.
To do that you will need a simple accessory – the Alzo Stereo to XLR Cable which allows you to take a 3.5mm cable and convert it into two XLR outputs – one for the main audio and one for the backup. Although we did not test this, it might be possible to use the cable to record into two different field recorders for a different type of redundancy.
