Frequently asked questions

Unfortunately these devices aren't supported yet, even if you are using Google Chrome.

Apple control what their iOS devices can and can't do, and so far the web technology we are using isn't available on these devices — we make quite extensive use of the WebRTC and WebAudio systems. We'll bring you more news when we have it.

Android phones or tablets are an alternative and we supprot these, using the Chrome browser.

Chrome on Android has a feature to annoying pop ups and ads from playing sounds; unfortunately this can interfere with Cleanfeed in some cases.

If this happens for you, you might need to change the entry in the chrome://flags page called Disable gesture requirement for media playback and select "Disable"; then re-start the browser.

Needless to say this isn't satisfactory! This feature is currently the subject of much debate; it seems to be interfering with many legitimate uses, and we're currently looking at our options. In the meantime, we'd like to keep track of this issue, so please send us a mail if you've been affected by this, and on which device/platform.

Either. You'll be set up in mono for speech by default. Just press 'Audio' to change to stereo.

We offer audio modes, optimised for speech (such as interviews or voiceover) and music (such as full outside broadcasts with music or production). These are the suggested settings to make the best of both audio quality and network conditions (minimal dropouts).

If the person you are communicating with is using headphones and USB microphone then it could be as simple as their headphones being far too loud, or around their neck and not on their head.

If either party is using a mixer, it is possible that they are sending the full mix down the line, when actually you need a "cleanfeed" or "mix minus" to be sent. This is a mix of everything except the other party. Setting up a mix minus can be a detailed topic and differs depending on your setup, but thankfully there is lots of existing material to help you.

On a broadcast mixing desk you can connect your PC running Cleanfeed up to the Telecomms channel. Your telephone might be already using this channel and already using a mix-minus. Possibly there is an extra 'line' 'line' input on this channel which is perfect for Cleanfeed.

If you don't have a broadcast mixer then it's also possible to create a mix-minus using the 'Aux' bus on a regular mixer; there's videos there there is lots of material on how to do this, including this video from the podcasting community which is a good place to start.

Finally, if you have a mixer with a USB input/output for recording then these can be ideal as they do not include the playback in the recording (ie. it's already mix minus'd.) But then podcasters will need to use another audio interface to record the "main out" of the mixer, not this one.

Yes, you can! And it's incredibly easy to use. When extra parties join your session they'll be muted by default, just select them to un-mute them.

Of course! We've been slowly introducing recording inside Cleanfeed for a while now; take a look at our blog post on Replacing Skype with Cleanfeed for information to access this today.

If you don't want to test beta features then you're back to traditional recording using hardware setups, and it's going to depend on whether you want to record the local side, the remote side, or both together. We can offer assistance here to enterprise customers; users of the 'free' Cleanfeed probably want to consult their local podcasting forum/group.

Some features we class as 'beta'. This means they are subject to change, known to be incomplete or not fully tested. We provide them as-is for your convenience, and with the hope that one day they will promoted out of their status as 'beta'. If you need to do something critical then you should consider carefully before using them, and also check the rest of our terms and conditions for the free Cleanfeed.

It will — the good news is that Cleanfeed should work anywhere that you are able to access secure (https) websites. Even if your web access is via a proxy.

We understand that corporate environments can be quite restrictive, and Cleanfeed will always try and search for the 'best' connection it can make. The latency may be compromised in such a restrictive network, but audio quality will never be.

Hopefully soon. Reliability is important for a service like Cleanfeed; whilst we have a version of Cleanfeed that works on Firefox in the pipeline we want to make sure it's fully tested before making it widely available.

You can, using additional software on your system. Try using Soundflower (Mac), or Virtual Audio Cable (Windows).

No, it won't. We don't believe in doing any additional processing your audio without letting you know. The audio signal you receive should be the best possible reproduction of the source, processed only by the codec.

You might find that consumer devices or soundcards sometimes add additional processing, though; especially on Android devices. Check your device settings.

Yes, the meter goes red when the signal is being clipped, which means the audio is already compromised before it reaches Cleanfeed.

This is most likely because your audio signal coming into your system is far too loud. We recommend that you turn down the input on system so that the meter is comfortably in the green. Refer to the documentation for your system and audio device on how to control the input gain level. This will ensure perfect delivery of your audio.

Cleanfeed LLP is a small internet-based company, started in the UK by Mark Hills and Marc Bakos; our background is in broadcast engineering and software development.

There are many other companies using the term "Cleanfeed" in their name, and we aren't related to them in any way.
