NOTE: In iOS 16 and above, many SDR websites do not work properly with this app. There are still enough sites working to use WebSDR for creative sound design.

WebSDR is an Audio Unit Plugin that plays audio from Software Defined Radio (SDR) streams. It allows you to incorporate the sound of live radio into a live music performance.


A software defined radio is a device with an antenna that connects to a computer and allows it to receive live radio broadcasts. It features a wide variety of protocols; in addition to standard AM and FM modes found in most consumer radios it typically includes modes for LSB, USB, CW and other settings used to listen in on the CB radios used by taxi drives, marine weather stations, air traffic control towers, amateur radio enthusiasts and many other types of radio broadcasts.

The signals you can access using this app are not your own local radio stations; rather they are the radio stations in the vicinity of a collection of free servers, many of them operated by universities. These servers are positioned in many different countries around the world so using this plugin you can listen in on a variety of radio signals in a wide variety of languages and cultures.


The crackly sound of an old-style AM broadcast or a conversation between taxi drivers on a CB radio is a musical flavour that can not be replicated with other plugins. If you are looking for some really unique and interesting material to include in your performances or mixes, this plugin will supply.


This plugin requires Javascript in order to play sound. Unfortunately that means that the UI must be open the entire time you are using it. When the UI is closed Javascript stops running, similar to the way a website stops playing audio when you close a tab in your browser.

It works EXCEPT…..

Sadly when using inside of AUM, the audio cuts out when you close the window. I wrote the developer but never got back a response. I’m a pretty experienced and seasoned ios music creator used to creating complex setups in AUM, Drambo, so it’s kind of a drag to have to squeeze down the window to a tiny little square and tuck it out of the way.

Developer Response ,

WebSDR runs on Javascript. In iOS devices Javascript only runs when the browser window is open. For this app, that means you need to keep the plugin window open somehow. If you’re running AUM you can work around this problem by opening the window and moving it off the screen in one corner so that it doesn’t block the view of your other plugins. In apps like drambo I am not aware of any work around other than keeping it visible on the screen at all times. We explained this in the app description but it’s good to clarify it here in this comment too so that future customers don’t get disappointed by false expectations.

We apologize for the confusion. If you bought the app hoping for it to work with the window closed, you can apply to Apple to get a refund through the App Store.

UI improvements, but no audio

UI has been improved and app itself has nice interface. But there’s no audio… only for a split second and then it mutes. No way to recover. Requesting refund. Will try again after the next update…

What? This is an App you charge $6 for?

I'm a ham. General. I took a chance and downloaded this App to hopefully enjoy some listening of stations I can't otherwise reach. So the program installs and I open it and what do I see? A Web page, with tiny font type that I can't read without stretching the dickins out of my iPhone 12. This is NOT an "App." And, it is NOT worth $6.

Developer Response ,

We apologize for the misunderstanding. I am replying to this comment to clarify and warn future customers. This app is an audio unit plugin. If you don’t know what that means then please do not buy this app. You will definitely be disappointed. Unless you run it as a plugin inside of an audio unit host like GarageBand, AUM, Cubasis, BeatMaker, etc. it will not do anything useful. The purpose of using it as a plugin is to extract audio from radio streams for use as an effect in music performances, recordings, and compositions.

When you run this as a standalone app, all it does is display the WebSDR website. You can access that website for free on your iPhone using Safari. So if all you want is to listen to the radio, please don’t buy this app. Just use safari instead.

We explained this in the app description but I understand that the app description is long and you may not have time to scroll down and read it all. Or perhaps you did read it but you didn’t know what we meant by “audio unit host”. That’s perfectly understandable and we apologize for the misunderstanding. If you bought the app based on a misunderstanding, you should contact Apple to apply for a refund.

Thank you.
