Fry sound when I sing clean notes
In the last few years I've been singing every day, I always warm up my voice for about 1 hour a day and I perform at live concerts at least once a week. In my life I've never had vocal problems, I always sing effortlessly, but recently I've been dealing with silent acid reflux and now I'm really concearned about a particular light fry sound coming from my vocal chords when I sing clean notes. I wonder if it's just a normal characteristic of my timbre, or it's some mucus caused by reflux that vibrates with the air pressure, or some kind of vocal issue going on.
So, I uploaded an audio file (click on the dropbox link below to listen to it) where you can clearly hear the sound I'm talking about.
Is there someone who had a similar experience? Let me know your opinions.
