I'm on a very fixed budget for a small Indie film that I am doing soon and I need better sound then the in-built mic on my Sony HD-SR10. Because my camera does not have an input for any external accessories such as the boom mic above, I need to record the audio separately and then edit it in post. But like I said I am on a tight budget and don't have the time and money to afford a $100-$400 digital recorder. I have read that you can plug your boom mic into your laptop and use a program to record the audio instead.
What I am asking is if anyone has ever tried that before and if so how did it work for you? And what specific program would record that? Audacity etc?
