Internet radio lets anyone with an Internet connection broadcast and reach a worldwide audience. With software such as SAM Broadcaster, you can stream music and voice directly to listeners or through a hosting service using ShoutCast or a Windows Media server. If you configure SAM Broadcaster to work with Skype, a free Voice Over Internet Protocol application, you can make Internet "telephone calls" at no cost and broadcast the conversation on your Internet radio station.
Install a second sound card or attach an external sound card to your computer. Your first (SAM) sound card or the integrated audio on your motherboard will control the audio output from SAM Broadcaster, and the second (Skype) sound card or external sound card will control the audio output from Skype.
Configure Skype to work with the Skype sound card. Open Skype, click "Tools," "Options" and "Sounds." Click "Mute All Sounds" to silence Skype sounds like ring tones and connection alerts. Click "Audio Settings" and set the "Microphone" and "Speaker" drop-down selections to the Skype sound card. Uncheck "Ring PC Speaker" and "Let Skype Adjust My Sound Device Settings." Click "Save."
Connect your microphone to the "Mic In" jack on the Skype sound card. Connect your headphones or speakers to the "Speaker Out" jack on the SAM sound card. Connect the patch cable from the "Speaker Out" jack on the Skype sound card to the "Mic In" jack on the SAM sound card. The sound from your microphone will be mixed with the audio from the caller on Skype and sent to the SAM sound card for broadcast.
Configure SAM Broadcaster to broadcast the Skype call. Open SAM Broadcaster and click "Config" in the VoiceFX window. Click the radio button for "Encoder" to directly send the sound to the audio pipeline. Set the record driver to "DirectSound Recorder" and the record sound card device to the microphone input on the SAM sound card. SAM Broadcaster will broadcast the audio sent from the Skype sound card when the Mic button is active on the Voice FX panel.
Adjust the sound levels on the Skype and SAM sound cards. The microphone setting on the SAM sound card controls the audio level of the sound coming into SAM Broadcaster from the Skype sound card. "Mic Volume" playback on the Skype sound card should be very low, to avoid overdriving the signal going into the SAM sound card.
Test the Skype/SAM Broadcaster interface. Call the Skype Call-Testing Service contact and watch the audio levels on SAM Broadcaster while you and the call attendant are speaking. If the levels are very low, adjust the "Mic Volume" playback slider on the Skype sound card to get the audio to an acceptable level.
Use a "Y" patch cable to monitor the SAM sound card audio on speakers and headphones at the same time. Connect the input of the "Y" cable to the "Speaker Out" jack on the SAM sound card and attach your headphones to one end of the "Y" and your speakers to the other end.
