Streaming High-Quality Live Audio Over The Web & Remote Mixing!
In the June 2017 issue of Live Sound International/ProSoundWeb, I wrote a brief article reviewing an exciting tool to send high quality audio over the internet within the Chrome browser — CleanFeed. I promised in the article to go into a bit more detail on my own workflow and uses for Cleanfeed.
This post aims to share my workflow for using Cleanfeed to teach, troubleshoot and take control of a console and “mix” the show — remotely. I’ll be adding more content daily, so stay close.
What is Cleanfeed?
Cleanfeed is low-latency, 2-way audio streaming software that, supported by the “cloud,” runs seamlessly on the Google Chrome browser with Windows, Mac, Android and Linux platforms. (No iOS support yet.) Simply launch Google Chrome, go to Cleanfeed.net, create an account, and off you go – send, receive and record superior live audio using only a browser.
Here are some screen shots of a fun test using Cleanfeed, TeamViewer and X-Edit to remotely listen to and control a friends X32 console.
I was in my New Orleans hotel room, my friend and fellow sound nerd, Mike Ingram, was at his studio in Cincinnati. He initiated a Cleanfeed session and sent me an invite. I joined the session and could hear the output of his X32 Producer which was connected to his audio interface and Macbook, respectively. Mike then sent along a Teamviewer invite so I could remotely control his Macbook and in turn, control his console.
The same can be done with other consoles that have companion software. As mentioned in the article, also having a stereo mic setup can give you a gentle representation of the room/environment.
Use Loopback (Mac) to route audio to and from the browser and other audio applications. Tip: Loopback is offering a special $10 discount to the Sound Nerds Unite family by using the discount code: SNURADINA.
“Speech Optimized” mode seems to be a great starting point in regards to sound quality and data. Yet, moving to “Music Optimized” is a great choice, too. Just see what works best for you.
This summer I’m headed out again to spend a few months turing knobs for my O.A.R. friends playing a ton of shows here in the U.S. Yet this time around, we will be joining big talents Train as well as Natasha Beddingfield — a great line up!
A bit different this summer
Usually I’m coordinating around 30+ channels of wireless daily. This breaks down to around 20 or so inputs (instruments and vocals) and 12 channels of IEM’s/ears plus spare packs as well as backup frequencies.
When O.A.R. is the headliner, much more control can be realized in regards to wireless. I often will coordinate wireless for the opening/support act also.
One difference this summer and this format is O.A.R. will be performing after Natasha and before Train which means there will be plenty of wireless to navigate each day.
A common courtesy with multiple band bills is acts will turn off their respective wireless when another act is on. This practice is quite helpful, and many times, essential.
Yet time is never on our side and being able to get a jump start on wireless coordination earlier in the day can be a huge help. In addition, often changeover times are brief and much can happen in those sacred minutes leading up to showtime. Being able to confirm your wireless is good ahead of time without stepping on another act is crucial.
Get to work early
I’ve found that being able to scan in realtime during an acts sound check can be quite reveling and helpful for my own coordination. Often my own gear will not be in place quite yet to perform a proper hardware scan. Using a tool such as the the affordable RF Explorer can be quite a powerful compromise.
Using this hardware scanner along with the free (PC only) and very powerful RF Explorer Software gives you the ability to see the RF environment in realtime plus export the data into Wireless Workbench!
If you play multiple keyboards, a common challenge is not having enough control over your monitor levels and the FOH mix. My solution may just help you!
I want control!
It can be quite challenging having to rely on changing your monitor levels at the PA mixer usually on the other side of the stage or relying on your busy sound engineer. (if you even get your own monitor mix!)
The big, heavy keyboard amp
Often multiple keyboards may be going into a keyboard amp such as the Roland KC350. The KC350, and the like, allows you to mix your keyboard levels, provide one “mix” to a line output and speaker in one convenient package. YET, if you would like to have control over the volume of each keyboard in your monitor, you need to find another solution.
Your own tiny mixer!
This solution simply submixes all keyboards using a small, inexpensive mixer, such as the Behringer Xenyx 1002b. This solution would combine each of your keyboards and send one mono (or a stereo) line to the FOH mixer and a separate line to a powered speaker for the your individual mix. This monitor mix is independent of the levels going to FOH — excellent! Just be sure whichever mixer you choose has at least one prefader aux send and as many line-inputs as you need. (tip: depending on your keyboards, you may be able to simply add a little velcro to the mixer and keyboard to keep the mixer handy and secure!)
A common scenario: You need to perform, talk or play music outside and need a sound system to help everyone hear but there is no power outlet in sight! I have a solution for you!
Batteries to the rescue!
Battery powered speakers of the past were never loud enough, weighted a ton due to the battery, and hardly lasted very long. With advances is battery technologies and power amplifier design, you now have many more robust, lighter, longer lasting and louder solutions! Plus, you can plug them in when power ins’t an issue!
For the musician, DJ or public event speaker, this little package can be an easy turn-key solution for your situation!
