DAR stands for "Digital Audio Recorder". DAR.fm is a personal recorder. Record radio streams and play it back at your convenience - it is the radio for your PC! Similar to how a DVR (digital video recorder) works with television DAR is a DVR for your radio; you can tune into any radio station on your PC. DAR can be scheduled to record radio shows or stations which interest you. Once recorded you can listen from a PC, laptop, smart phone, internet radio or other device. You don't have to leave your computer turned on. Once a schedule is setup, then DAR.fm is directed to store the material at your direction and will capture the recording at the prescribed time.
As soon as parts are recorded and stored they are available for listening. For music stations this happens in about 10 minutes from start of the recording. For talk shows they are recorded in multiple parts of 15 minutes each and after about 30 minutes the first part will be available to listen to once you record the radio stream.
Capture 2 GBs of streaming audio for free! This is enough to store approximately 100 hours of streaming. However, it depends on whether the material you are recording is talk or music - you may be able to store more or less. If you need more space you can sign up for a Premium account.
