Spreaker (free) just went live in the App Store this morning and it does for audio what Twitter does for text (and YouTube does for video): it makes it easy to share audio content across social networks.
Spreaker allows you to broadcast live audio from your iPhone (and soon from Android too) directly to your Facebook page. You can also use it to capture audio which you can listen to and distribute later as a podcast. The Spreaker website allows you to edit your recordings and easily add sound effects and background music.
The Spreaker app has a lot of potential and I look forward to taking it for a spin on one of my seemingly endless commutes. In fact, it might be a great way to resurrect the PowerPage Podcast, which has been dark for a while due to scheduling issues.
