What is Echo Cancellation? A 5-Minute Explanation

What is Echo Cancellation? A 5-Minute Explanation

WHAT IS ECHO CANCELLATION? BEST PRACTICES FOR CLEARER AUDIO IN VIRTUAL RECORDING In the world of virtual podcasting, how do we eliminate echoes during our recordings? Echo cancellation is a crucial technology that can enhance audio quality, yet many podcasters don't know how it works and when to use it. Here is what it is, how it operates, and best practices for achieving pristine audio in your virtual sessions. WHAT IS ECHO CANCELLATION? This is a technology designed to remove echoes that occur during audio recordings, particularlywhen podcasters aren't wearing headphones. If you’ve ever heard your own voice bouncing back at you, you know why we need this tool. HOW DOES ECHO CANCELLATION WORK? In a perfect scenario, everyone involved in a virtual meeting or podcast recording would wear headphones. This simple act reduces feedback and eliminates echoes. However, this isn’t always possible, especially when guests join without headphones. Echo cancellation smartly mutes your microphone when sounds from your speakers are detected. For instance, if you’re the host and your guest is speaking, the software recognizes that sound and prevents it from being picked up by your mic, thus eliminating any echo. This process is used with many platforms, including Zoom, Riverside, and Zencaster. COMMON MISUNDERSTANDINGS Many people assume that if they hear an echo, the issue lies on their side of the call. However, think counterintuitively. If you hear your voice echoed, it typically means the other participant's microphone is picking up your voice through their speakers. In such cases, they need to enable echo cancellation. If you hear the echo of the other person, you should activate it on your end as well. THE IMPORTANCE OF HEADPHONES Ultimately, this feature should be a backup for when headphones are not available. Ideally, everyone should wear headphones, as this eliminates the need for this tool altogether. If there is still an echo with headphones on, try turning down the volume on your headphones, then your microphone. LIMITATIONS OF ECHO CANCELLATION While this is a powerful tool, it is not foolproof. You've heard this when two participants speak simultaneously, leading to distortion or muddled audio. This is often described as an underwater sound, indicating that the feature is struggling to process overlapping audio inputs. BEST PRACTICES FOR CLEAR AUDIO 1. Use Headphones: Always encourage guests to wear headphones to minimize feedback. 2. Enable Echo Cancellation: If headphones cannot be used, ensure that echo cancellation is turned on for all participants. 3. Adjust Audio Levels: Monitor microphone and speaker volumes to avoid feedback. Lowering the levels can often resolve echo issues. 4. Conduct a Scratch Test: Before recording, perform a quick scratch test to confirm that your microphone is correctly set up. If the other participant can hear the scratching sound, you’re good to go. If not, check your audio settings. CONCLUSION Echo cancellation is a valuable tool for enhancing audio quality in virtual recordings. Understanding its function and limitations can greatly improve your podcasting or virtual meeting experience. Remember, the best solution is to use headphones, but in their absence, this tool can be your ally against feedback and distortion.

Beware of Pop-Up Podcast Studios!

So just a short abbreviated version of the Jag Show today for a couple of different reasons. Okay, first off, I'm doing a little bit of testing. My partners over at Simplecast, they are the podcast hosting platform that I've used, are rolling out a feature for some plans where you can upload your video into Simplecast and automatically connect to your YouTube. So you don't have to upload your audio and your video in separate places. If you're doing a video podcast, you put the video in one place, it populates to your YouTube, done and done. And there's also going to be the availability to check analytics from your YouTube through Simplecast all in one place. I love the idea. I've been working on them, getting some kinks worked out of it. And of course, I'm going to test it for myself before I roll it out to my clients. Okay, the other thing that I want to talk about today is podcast studios. Now, I know some folks prefer to record in a studio. They really like that feel of having a face-to-face conversation with somebody. They feel something gets lost when you're on Zoom or on a screen like we all felt during COVID. But please, if you're going to go to your... But please, if you're going to go to a studio, please vet the studio before you go. Anybody can buy a thousand dollars worth of equipment, set it up and say, hey, we've got a podcast studio. I know of a client of mine that went to a podcast studio, did not know any better, not on them, but they recorded in the podcast studio on Riverside and sent me the files. But when I got the files, the video dimensions were off. It wasn't 1920 by 1080 or even 1280 by 720 or even 4K. It just wasn't the right dimensions. So what I then had to do, and there were only two cameras, there was a camera on each participant, but no wide shot of everybody. So that took a little bit of creative video editing on my side to get everything to look right, to look like a normal conversation. Now, I'm not going to fault the studio. There are very fine folks that run the studio. But if you are going to start a podcast studio, consult with somebody that knows how to set up a studio first. And then if you're going to use a podcast studio, take a look at some content that's been produced there or ask them some questions. Make sure it's the right place like everything you want to do your due diligence. Now all that said, I am still a huge fan of the Riverside platform. It's what I'm recording the Jag Show on right now. I'm recording in 4K thanks to my Sony... What is it again? I'm recording in 4K with my Sony camera and my, as you can see on the video, my Shure SM7B microphone plugged into my Rodecaster Duo. And I posted about this on LinkedIn. Shout out to my friend, Kristin Donnelly, who asked, can you record two people in person on Riverside? Yes, you can. If you have an interface or mixer that two mics can plug into, you can separate out the audio feeds. The only catch is you're going to have one camera feed for everybody, so make sure it's a wide shot. Or if you're on Apple, you can use your iPhone or iPad as a continuity camera with your Mac. If you're not on Apple, you can use the Riverside app on an iPhone or an iPad or an Android device to be a second camera in the session. You can go between the different views. So there's that too. If you have any questions about Riverside recording remotely or recording in person, please feel free to reach out to me, jag@jagpodcastproductions.com.

Comcast Rant

Who doesn't love a good Comcast rant? My wife and I moved over the holidays – but this story starts way before that.  We couldn’t do Fiber internet in our old house for technical reasons, so we reluctantly switched over to Comcast and Xfinity.  At the time, we were both working from home – and we BLEW through the data limits for their residential service. I figured it was all of these live podcast recordings, uploads, and downloads. Turns out, it was her being on Microsoft Teams calls all day. At any rate, we had to upgrade to a Comcast Business account.  Fine. In December, we were fortunate in that we had a couple weeks of overlap, where we were still in the old house, but transitioning into the new house.  So I called Comcast, and explained I needed the service in BOTH locations.  The sales rep seemed OK with that, but told me to contact him as soon as the new service was installed, so he could try and keep up all my discounts, which were unusually high, in his estimation.  I emphasized, DO NOT TURN OFF SERVICE to the old house when the new house is turned on. Cut to December 18th – my birthday, no less. I spent the entire afternoon at the new house, waiting for the install. The older gentleman tested the line and told me the connection wasn’t great. So he climbed the utility pole in our new neighbors’ yard, and ran a coax line across the top of their fence, and ours, into our house. Turns out, our electricity line is underground here – great for a storm – bad when the cable company has to, by law, follow that line. So they opened a ticket to have someone come out and bury the line once the ground thawed. Meanwhile, there’s a giant red coax cable strung across our neighbors’ yard (fortunately they are super nice), and ours.  Cable comes on, and my wife calls from the old house – sure enough, they turned the service off, over there. What followed was 15 minutes of me cussing out an automated system at Comcast, because it was after hours.  Finally, I get a human being, overseas, who tells me to unplug it and reset it.  I explain, no, it’s not a technical issue – it’s a YOU issue.  “Oh I’m sorry, you’ll have to call back after 7am.”  Uh, no. This may be a first world problem, but I have too much stuff in my house that relies on the internet to have it off overnight due to your incompetence.  I said it a little nicer than that.  Miraculously, they turned it back on. First bill comes – for FIVE HUNDRED DOLLARS. This includes the install (fine), and two months of service – at $50 per month more than I’d paid all last year.  That’s the straw that broke the camel’s back. I called AT&T about fiber. They came in at $80 per month cheaper, no data limits, and excellent customer service. Not to mention they are symmetrical – their upload speed matches their download speed.  I’m doing more video for my podcast clients – and an hour podcast, at 1080p resolution can be around 6 Gigabites. To upload a file of that size would take an hour on Comcast.  With AT&T, it’s usually a few minutes. SOLD. So I cancel Comcast. But in the interest of being a good neighbor, I need to get the cable removed from their yard and ours.  Dead end, after dead end on phone, and chat. I’m pretty sure, Comcast having the monopoly that they do – the system is designed to get you frustrated and just give up. But then my good friend Diane entered the picture. She told me there’s a REDDIT thread for Comcast support. And she suspects the agents that are too good for the phone and chat get “banished” there. It’s some sort of secret society. Long story short – I posted about the issue. A moderator DM’ed me, and despite a few hiccups, eventually someone came and removed the line. So THAT problem was solved. That only leaves the bill. Reddit couldn’t help me there because once I admitted it was a business account, they very quickly said “not it!” On January 15th when I cancelled the service, they had the audacity to tell me I was past my 30 day cancellation window. I told them no, I spent my BIRTHDAY on the 18th waiting around for your installer.  So they processed the cancellation.  Look, I’m a reasonable person. I don’t expect a refund for the installation, nor do I expect to get my money back for the first month of service that I used. But I damn well better get my money back for the second month of service that was NOT used.  They told me to wait until the February 14th bill to see the refund. I got the Feb 14th bill – and have a credit OF…18 dollars and 18 cents.  Still no refund for month 2.  So I tried the chat – oh you have to call our retention department – which sounds like AI but I think is a person.  After 30 minutes on the phone, I come to find out – they are insisting I’m was out of my 30 day window on the cancellation because even though the install was on the 18th, the CONTRACT started on the 15th. They waived my cancellation fee as a COURTESY. How nice. As for the refund on the second month of service – when I went back over the fine print of the cancellation document I signed – it said the cancellation will take 30 DAYS to process and I’m responsible for those charges. You win, Comcast.  I’m tapping out.  When you own your own business, you have to think about what your time is worth. And even though I wanted to die on this hill, I can’t spend any more time fighting for $150.  But I sure can post this rant on the internet and hope a bunch of people see it.  It’s the equivalent of the strongly worded letters my parents taught me to write in the 80s. I will say though – if you are stuck in Comcast or Xfinity automation hell – try Reddit. You might find a diamond in the rough. And a note for podcasters – fish where the fish are. Leave no stone unturned for where your audience might be hanging out on the internet. Next on my to do list – trying to get money back from Verizon. They charged me for an ipad I traded in – for 14 months after I no longer had the device. Wish me luck.  Find jag on social media @JAGPodcastProductions or online at JAGPodcastProductions.com [https://JAGPodcastProductions.com] Hosted by Simplecast, an AdsWizz company.

Protect Your Podcast From The Next YouTube Outage!

If you're one of those people who only does your podcast on YouTube, last week you were in big trouble. Last week, YouTube had an outage, which is prone to happen in all these big tech companies. And if you only have your podcast on YouTube, not on Apple, Spotify, or anywhere else, you can get it on audio or video. Your listeners couldn't consume your content and they went somewhere else. Take it as a really important lesson. Do not put all of your eggs in one basket. Similarly, today, Amazon Web Services AWS, they also had an outage which affected apps like, , Snapchat and others. I have a 15 and 20-year-old niece. Their primary method of communication isn't text. It's snap. Good thing they were in class today, otherwise they would've been in trouble. Here's the thing, we are very, very vulnerable as a country to cyber attacks. I'm sure there are bad actors all over the world licking their chops right now. Can't be a coincidence that YouTube had an outage. Amazon had an outage all within the span of a week. You never know what is going to go down when. So be sure to have your podcast in as many places as possible so that if something goes down, your content can be consumed somewhere else. Because if your listeners and viewers can't find your content,. They'll go elsewhere. Hopefully they'll come back.
