The digital video recorder is one of the greatest A/V inventions of all time. Having programming available when you want (and in some cases, where you want) has truly changed the way that we watch TV. Now, if only someone could do that for radio.

Well, it looks like someone is working on it. According to eHomeUpgrade, Michael Robertson, the founder and former CEO of MP3.com, is in the process of launching DAR.fm. This service adds DVR-like functionality to web radio.

DAR (which stands for Digital Audio Recorder) allows you to choose what you want to record by station or genre. From there, you can record live content or capture a show in the wee hours of the morning. One pretty cool option is that DAR.fm lists popular talk radio shows, so even if you don’t know dates and times or call letters, you can still find favorite programs.

Once the content is captured, you can choose to play back your recordings through a web browser, a mobile device, or even a digital media streamer that’s hooked up to your home theater system.

Of course, this isn’t the only service of its kind, but it certainly appears to be the easiest.

DAR.fm currently works with the iPhone and iPod touch, as well as Android, Windows Phone 7, and Palm smartphones. As far as home devices, the service is compatible with Roku, Logitech’s Squeezebox line, Audiovox Infinite radios, and Grace Digital web radios.

Some methods do require a fee for the service. Check out DAR.fm’s website or the launch announcement below for more details.
