Excellent work, bluejet...thanks so much for submitting. As much as I like the graphic (and I do), it doesn't say "broadcasting" strongly enough to me. Could be medical even if it weren't for the text. If you're interested in putting in more work I would suggest incorporating a microphone in some way.
That said, this is very simple, very clean...both things I quite appreciate.
This is my personal favourite, As voice imaging is what you do literally, this icon image is a butterfly made from soundwaves, which can also represent levels. I believe you shouldn't over complicate your logo, it doesn't need to say everything about you, or anything for that matter. It should be an attractive and interesting representation of you and/or your business/profession.
Wow bluejet, you're an extremely talented designer. It's good to hear that I could be overthinking it, as I am definitely capable of doing this. I see the butterfly but I don't think that's something that represents me to be honest. Definitely a great creation though, and quite skillfully done.
Thanks very much for offering your submission and for sharing your viewpoint.
