A live outside broadcast

If you’re a radio station, Cleanfeed is an excellent way to send live audio back to your studio from an outside broadcast at a remote location.

This sort of thing that would, in the past, need expensive ISDN lines or other specialist radio equipment. Now with Cleanfeed it’s easy and economical to get a full quality stereo link back to your studio from anywhere with an Internet connection, and even two-way when you need it.

Now you can focus on the show; it could be a music event broadcast live on the radio, or host a discussion at a local cafe or bar with listener interaction. Let your creativity drive you, just follow our guide.

Sign up or log in

Using the Google Chrome browser, sign up for a free Cleanfeed account. If you already have a Cleanfeed account, log in to the Cleanfeed studio with your login name and password.

If this is the first time you’ve logged in to Cleanfeed, you’ll be asked to give us permission to use your microphone. Cleanfeed won’t work without that, so you should Allow access.

Your audio hardware

From the main Cleanfeed studio screen, press the Gear icon at the right side of the grey row showing your name. From the drop-down menu listing available devices, select your microphone or audio interface. You can also tell Cleanfeed how to take audio from that device. Normally this should be set to Both to capture left and right stereo from the device, but you might want to explore the other options.

Use the Gear icon to select your microphone or audio interface from the list.

If you don’t see your hardware in the list, wait a moment and then try the menu again. If it’s a USB device, sometimes it will take a moment before the device is available to your browser.

Remote audio quality

We’re going to set up our remote audio specifically for the type of programme content.

Press the Audio button at the top of the main Cleanfeed screen. Then, from the Remote audio quality drop-down menu choose one of the following:

The input meter

To the right of the green and white Microphone icon , and to the left of your name, is a small vertical audio meter.

This meter is a visual indication of the level of audio coming from your side of the link. Too high, and the meter will show red. Too low, and you will only see green on the meter. For best results, make sure your microphone level peaks in the yellow area of the meter, between green and red.

Keep the input meter touch the yellow area for the optimum sound quality

If the input level on the meter is not touching the yellow area, you can adjust the input level. For the best sound quality, and to avoid hissing or ‘noise’, turn up the dial on the microphone or audio interface before boosting the level using the computer. Consult the instructions from the device manufacturer for more details.
