I have had a great opportunity to test out the new Boya SM-80 microphone this afternoon and recorded in MP4 format for a change as that is more acceptable for youtube. Best heard with earphones to get the best of the birds singing
Pity the video is downgraded from the original over the internet
Ok, just for you, I dug out my earphones, and yes the birds are louder (more of a racket than tweet tweet though) however you might want to try and separate the sound of you twiddling the controls, because that gave me a fright!
Just listened on my new AKG head phones (bust my sennheiser on ears). They sound real clear and separated. Checked for bird poo. @realspeed you must have loads of birds in your garden.
