From my pal Curtis:
Hey Juan, Do you know how I can upload my vo demo to my fb profile? Or is it best to link from another page to fb?So here's the deal Curtis, we've never had great solutions for hosting audio online. You'd think in a world of streaming HD video, there's be SOME place we could semi-permanently host high quality streaming audio files like Youtube.
Recently, services like SoundCloud have become popular, and their bandwidth caps aren't horrible if you're focusing on something like your demos. The nice thing about SoundCloud is that it not only offers a handy place to upload the demo, and tools to embed the audio file on other sites, but it also makes it pretty easy to share your demo with a variety or services and social networks.
The tricky thing about directing traffic to web pages and social networking is you'll find people have very little patience. There's about zero attention span online. If someone finds you through Facebook they might not follow you to another link posted on your profile. Vice-versa if someone finds your web site, and you try to ship them off to Facebook or another service.

But Facebook doesn't allow audio uploads do they? Well this is where all these streaming video sites might actually come in handy. Come up with a static image, a brand logo, something with your name on it, contact info, and convert that demo to a video file where it can live on Youtube, Vimeo, Facebook Video, etc.
Between SoundCloud and streaming video, you should have plenty of options for making sure that your marketing materials are easily accessible regardless of how someone might find you online.
For the rest of my VO audience, what services have you utilized for sharing your demo? Have I missed anything which might help people share high quality audio? Drop me a comment below!
