Frequently asked questions

One of the most common problems we see is a typo in the email address. Select the 'profile' button (top right) and verify the information given on sign up. Correcting the email address will send a new verification email.

If the address is correct, there's an number of things could be preventing delivery.

Some internet providers operate a 'greylist' which means the first email from Cleanfeed may take 15 minutes (or in extreme cases, several hours) to come through.

The mail may be in your 'spam' folder. If you do find it there we'd appreciate if you can make it as "not spam" to limit the effect on other users.

In the worst cases, you may need to use an alternative email address. Updating the address in your profile will send a new verification email.

Logged in to Cleanfeed, you can easily change your capture device. Select the settings (cog) icon next to your local audio, and use the drop-down menu to select your audio device.

Cleanfeed uses your system's default playback device. Check your "System preferences" or "Control Panel".

Subscribers to Cleanfeed Pro may choose to have Cleanfeed use a dedicated audio interface. Select "Audio", "Playback device" from inside Cleanfeed.

This feature is in beta testing. To begin with, we're testing it for guests only — you can't use it to host a Cleanfeed session just yet. But since all your recording happens at the host side, you can use this to record, eg. an interview with someone on an iPhone with considerably better quality than a phonecall.

Android phones or tablets are an alternative to host a session, and we support these with the full feature set, using the Chrome browser.

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.

You stay in control at all times, and parties will be able to hear one another. We find this is excellent for conferencing, too.

No it's not. Unlike some of the other solutions your recording is made live, there's no need to 'sync up' a recording at a later time. This makes Cleanfeed usable for live content, as well as pre-recorded interviews. The quality of Cleanfeed's live audio is at the absolute forefront of what technology as to offer, and is what makes this possible.

No, we don't limit the lengths of recordings in either the standard (free) or Pro versions of Cleanfeed. You browser will retain recordings on disk during the session, so usual technical limits on disk space apply, and the amount of RAM should not be an issue.

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.
