If you’re watching a stream there are a few frustrating things that can happen: the video can freeze or skip, the quality could be bad, or the sound could be difficult to understand or hear. Here we wanted to offer a few tips to help with your stream audio. Sometimes problems are unavoidable depending on the situation of the end user, but here are a few things you can do to make sure you are producing a good audio mix.
Mix to Headphones
- Mix to headphones. This will help cut out any disruptive noise and make sure you are accurately hearing every detail. Then check it on bad speakers and bad headphones. What does that mean? Most people who are watching a live stream aren’t listening to it on a high dollar, custom tuned sound system. Most people are listening on their phone or laptop or on a pair of headphones. So, create your mix to sound good on that! If you’re doing a live stream, be sure to do a test first so you know what will sound good on those phone speakers.
There's a lot going on right now, so where do you even start when it comes to your network?
Your first move should be creating specific goals for what you want your streaming options to be. Broadcasting systems can range in price from thousands of dollars to millions, so having a clear idea of how you want to use your system is important. Who do you want to broadcast to? Will you be streaming from multiple locations? How will your participants access your video, and from what? How often will you be recording? Will you require archiving video for future use or will it only appear once? Do you want to show a single camera, multiple cameras, and do you want to include graphics as well. Once you’ve written the answers to these questions our team can better help you find the equipment you’ll need.
Hey guys! Trevor here, shop manager and lead install tech for Lambda, and overall Audio Genius (That last one is a bit of a self-given title… but I’m keeping it). Along with working for Lambda, I am also an Audio Engineer for at a local church in Colorado Springs. Last week with the beginning of shutdowns due to COVID-19, most of the live production world came screeching to a halt. This included auditoriums and houses of worship. So, we wanted to share how we took a 2500+ group of people meeting over a weekend to an online only platform in a matter of 36 hours.

Last week we gave you the first three of seven things to know about LED wall. Here are the last four!
There's lots more to know about LED wall, but hopefully these seven points will give you a start into knowing more. If you are looking to add LED wall to your system, and want to know more, schedule a Site Spec with us so we can talk you through all the details of having LED.
7 Things to Know About LED Wall. Part 1
Video walls are become an increasingly common component in most audio visual systems. Video walls are exciting additions to any audio visual system, but is it right for you? The price is starting to come down as the quality and density of the LED pixels goes up. They are being designed to become more interactive and they can be visually exciting with lots of display designs. It may only be a matter of time before LED walls are everywhere we go, but before you decide to jump on this popular bandwagon, here are seven things to help you understand more about LED wall.
Whatever size of video wall you choose, you probably already know that it will be an investment. Now certainly the cost shouldn’t turn you away if you know video wall is your best solution, but it should be considered carefully. You should consider if you need to invest in other equipment or just the proper infrastructure for LED panels before you invest. For example: LED wall does not save energy it uses almost 10 times the power of a laser projector if not more. Will you be able to support the additional energy cost?
One of our favorite installs...
Douglas Valley Middle School, from District 20, came to us with an audio problem in their gym. The school had an aging audio system. The cables were a mess, no one really knew how to work the system, and it wasn’t really serving the school’s needs. We asked the PTO what they were using the gym for and the needs were pretty simple. The school staff needed to be able to hold an assembly, play music for gym classes and connect audio from a DVD player for movie night. The gym also doubles as a theater with a small stage for school programs and activities. The PTO and teachers also specifically requested a system that didn’t require them to know audio theory or reference big training manuals. They were looking for a quick, simple and effective fix.

What does it matter? I can do it myself...
There are some who feel like they do not need a professional integration company or an Audio Visual design engineer when they change the AV system in their business. Perhaps they have a background in operating tech or maybe they are quick learners and feel confident they can easily plug new equipment in and start using it for a new project. Where there is a possibility you could get away with this once, chances are things won’t go according to plan. We’d like to take a minute to tell you why you need to consider having a professional Audio Visual Integration company for your next system install.
