Rob Nokes Go To Mics For SFX Recording

Matt: …sort of microphones you must have a complete warehouse of everything for all sort of things but other types of microphones that you’re kind of always taking out as they’re kind of wanted to kind of make some models? Rob: Yeah I mean everybody who knows me...

NAB 2017 Rundown

now that we are halfway through NAB 2017 I wanted to try to make a list of everything that’s been released or shown in one easy list. This is mainly aimed at production mixers but ive thrown in a few post production items too.

Hiding A Lav In A Childs Bike Helmet

Just wanted to show you a quick guide to micing a child’s helmet. This work such a treat! The pack could have been hidden in the helmet as well but it was a bit uncomfortable for her so with help form makeup and costume we hid it in her long hair and in the back of her hood…..

Q&A #26 – The downside of line inputs without trim pots!

In regards to the Sound Devices 6 series mixers (633 / 664 / 688) what are the downsides of any inputs without physical trimpots? The trim pot is what you use to increase or reduce gain to your track. The tracks without dedicated trimpots on the 6 series recorders only accept line level and though gain can be changed, it is through a menu on the screen while recording, thus limiting you to changing one at a time.

Q&A #22 – People think cameras are more expensive than Sound.

When it come to crewing and getting a film together the most expensive element of the film is usually the crew cost for labour followed by rates for different departments. Lots of people however with the price of mid tier cameras dropping all the time automatically think sound is doing the exactly the same thing. This is because they have worked with lower cameras and also where the sound was done on a zoom.

3 Areas To Focus On To Make More Money

Money is always a hot topic for freelancers. If you are low or having cash problems then I would focus on these 3 areas to figure out where you are weak. Then once you plug the gap you should stop seeing money just pass you buy and have more chances to give more value to your clients.

Q&A #13 – Are IFB/IEMs essential to own?

This was a question from one of the previous Q&As about how essential i think IFB/IEMS are. I took this to mean buy some to use in equipment on many jobs. For that reason I would say it wouldnt be something I would look to buy early on but they do come in handy for bigger jobs or commercials when clients and agency are wanting to listen in while watching video village.

For More Work: Focus On What You Have Already

Continuing the theme of getting more work as a freelancer I wanted to cover the concept of focusing on what you have instead of what you haven’t. Might sound silly but in practice is very lucrative as you maximise value to the clients that keep hiring you and in turn become more appealing to other clients through referrals and word of mouth.

What I Do When Work Dries Up

This is a common issue especially for newer freelancers, work drying up. The trick is to be able to predict these dry spells as best you can. Often your client base will be made up of a mix of people making regular content but some may make 2 projects a month, some 1 project every 2 years. Having a wide array of clients and project types should keep you working all year round.

Q&A #11 – Is the SuperCMIT worth the extra money?

I own a SuperCMIT and have done for over a year now and do think it is an excellent tool because you are still able to record an unprocessed channel and a processed channel with its noise reduction algorithm. This means that at the worst case if post production (often me doing it) I can use something like Izotope’s RX5. If I am not editing then I can give them a clearer signal that the client love.

Q&A #10 – Why Are There Different Rates For Different Types Of Content?

I answer this question by the economics of the content basically. Commercials pay more because the upside of the piece of content is much greater than the cost of it. If you do a worldwide commercial for a popular brand then they are going to make, realistically, a ridiculous multiple on the amount spent on the commercial, even if they go 2 days into overtime for everyone. Also the complexity of these projects is usually higher. 

Q&A #7 – Is it Essential to move to London for UK work?

I was asked if it was a sensible move to go to London to further my career. For me it was because I was based in Dundee in Scotland before. Being 500 miles away from what is arguably the Cultural capital of the UK It just made the most sense. Here are a few factors you have to weigh up when moving to somewhere so expensive and big.

Q&A #3 – Tips to getting paid on time

Might sound silly as when you set your invoice terms (Usually 30 days) then the client or production company should pay you on time, but this doesn’t happen 100% of the time for me. So there are a few things you can do as gentle reminders to help maintain your cashflow and all the adult things like rent and bills.

#1 Reason For Weak Wireless Mic Signal

Often on shoots, especially drama, you need to hide your transmitters, but often some people have complained about range issues in certain positions. 

This is usually because the body is taking out and blocking the signal being sent. This is also to do with if the antenna of the TX pack is touching the actual skin of the talent. When this happens your radio mic signal range will be impacted.

Whats In My Peli Box?

This is a quick overview of what I typically have in my peli box for a corporate shoot. I’m using the Pelican 1620, great case for travelling and getting everything in.

Moving House and Freelance Finances

So recently I moved house and wanted to share some insights into finances because as a freelancer it can be tricky to manage. Also having a self employed status you need to make sure you take into account about your profit and loss.

The Soundrolling App [Beta]

Hey all, this is an app i’m developing to help get more of the best bits of the resources i’ve gathered over the years into the palm of your hands. This is currently still in testing and so only currently available on Android mobile devices. Let me know in the comments if you would like to see it on Apple IOS and ill try to sort that out, but they want £150 for putting just 1 version up there, 99/year for an account and then £49 for uploading versions of it, so may have to charge  a few quid to cover that cost. Anyway let me know.

Why I Am Now A Director Of Sound

More and more I have been overseeing productions from location sound, right through to the final mix. I have always been honing both my production and post production skills but have mainly focused on where I felt I could deliver the most value to productions. There is nothing to truly replace a great performance than the sound from the location.

Mandy.com has been sold to Blue Compass

It’s come to my attention that Mandy.com has been the same company (blue compass) as film and tv crew pro. This in my opinion makes it the largest jobs site for film and TV jobs in the UK. With over 300,000 unique views a month. This means however that you will have to pay to view paying jobs)

16 Bit vs 24 Bit Audio

What is NTSC / PAL / SECAM?

NTSC / PAL / SECAM  Due to the frequency difference of the AC currents of different regions we end up with these two different video recording formats. NTSC North America, parts of South America, Japan, Taiwan, the Philippines, and South Korea have AC current at 60Hz,...

What Is LTC? (Longitudinal Time Code)

LTC stands for Longitudinal Time Code. This is a audio signal which transmits a series of square waves from a “Master” device. The Master device would be the main device you are running the timecode from, this could be from mixer to camera or separate timecode box to a mixer or camera.

What Out Of Phase Sounds Like…

Below is a little video I shot in Pro Tools and I give you an example of what In Phase and Out Of Phase sounds like. This also ties in with wave interference so I show you the resulting effects of the same clips of me talking “in phase” (aka perfectly matching) versus just a single source.

The Half Power Point and Pan Law

The half power point essentially establishes that a -3dB difference is half the power of any frequency played through a speaker. A mono signal played through 1 speaker is going to be 100% volume, but when played through 2 speakers you have double the speakers so essentially only need half the power from both to perceive no change in level.

Lectrosonics SMB Tutorial

This is a really great piece of engineering. Very good range and limiters are the biggest bonuses to the Lectrosonics SMB over other models like the Sennheiser G3 wireless (which i still use) working with the sound devices 664 I think they make a brilliant team. There is also the double battery version which lasts double the amount of time. I have 2 sets of both for different miking requirements.

Wait a minute, now there is sound in space?

Despite what you’ve not heard, there are actual sounds in space. Though not as we first thought about it. I’m sure you have all seen the bell in a jar experiment.

Due to the virtual vacuum in space, it’s not sound like you and I experience it (that being waves pulsing through the air), but there are electromagnetic waves that pulsate at the same wavelength as the sound waves we can hear.

Setting Gain: How to set gain levels

In the audio world and other areas involving electronics, gain is a measure of a circuit’s ability to increase the power or amplitude of a signal. This is added from the input stage all the way to the output stage. Gain works by adding energy to the signal from a power supply. This is why if you keep adding gain, you keep adding noise that comes from adding extra energy/power.

How to coil cables

This is how you should coil cables in the film industry. This is to stop kinks and knots that end up destroying the inside of your cable. You want to keep your cables in the best condition possible, without them you are stuffed.

On Set Filming Etiquette

This is not some sort of disease but how generally you are expected to behave on location/set in the film industry. These are open to interpretation but these pointers will give you a nice outline of little rules and tips to help you. Lets start from the basic to the industry jargon.

Sound Recording Action Scenes

Sound Recording Action Scenes usually means that there is no dialogue apart from cries of pain and screams. For a production sound recordist this means that you are trying to capture as much as you can within the takes to give the post production team a good idea of what it sounded like on the day.

Track Assignment

This article discusses how to arrange your recording or mixing tracks. Every input into your mixer / recorder goes to a varying amount of tracks.

In the case of the Sound Devices 664, all inputs get their own track which is recorded and the ability to send to 4 mix tracks. If you just have a mixer like the Sound Devices 302 then you will only have 2 tracks at all times, a left and a right mix track. Track Assignment therefore varies depending on equipment so lets look at a basic scenario and then work our way up.

Why You Need The Best Wireless: G3 Vs Lectrosonics

This is an obvious title in a way, after all of course you need the best of everything right? Well this is a post that explains my previous thoughts about having a set of G3s and then making the big jump to the Lectrosonics. This post is for other people that are weighing up with the decisions of which brand to go for. Now i am obviously talking about Lectrosonics from the Sennheiser G3 wireless.

Bone Conduction: Sound Through Your Skull

We are able to perceive sound thanks to our brain decoding all the various frequencies collected through our inner ear. This is not just done with the ear but also directly through our skull. This is now being utilised through technology like google glass. This is thanks to mathematical and computational models by researchers to understand the whole process — bone conduction — works.  Along with technologies such as Google Glass, it is looking to be utilised in medical equipment, their paper was published this week in Nature Communications.

The New Harley Davison Sound

It looks very slick and sounds even more futuristic than Tron. The trailer for it below gives bites of the new Harley Davison sound.

We shall see more and more of the electric motor sounds in the future as everyone makes the switch. I wrote an earlier article about how cars are already designed with sound in mind, all as part of creating a driving experience that will add more value to the car. This is the same idea that is being implied by electric motor designers that want to turn the tide of boredom and weakness that is associated to electric motors. The quiet, slow, heavy car sounds of the past.

The Sound Of Happiness

Words can obviously affect the way we feel. I recently came across an article that actually puts more emphasis on the individual letters in a given word rather than the meaning as a whole. The main take away from  researchers in Germany was the power of vowels.

During the research they wired up participants to measure changes in their facial muscles linked with smiling and frowning. Out of all the letters it was found that the letter ‘i’ was the most positive, particular a long ‘i’. To me this seems obvious when we think of the meaning of the letter its self, for it is also a word really.

A Simple Audio Illusion

This is a sweet audio illusion recently brought to my attention on Facebook that is quite neat. I have touched on the topic of brain discrimination only very briefly before because it is such a deep topic. Brain discrimination is basically the idea that you can focus on sounds you want to hear (within reason) and so reject other sounds indirectly.

When to say echo or reverb?

The terms echo and reverb (reverberation) are often used on location interchangeably. Being a sound recordist you have to explain sonic phenomena to people in a quick and simple way. I am always trying to educate everyone to save any future confusion. So should you say echo or reverberation?

The Pic ‘n’ Mix track

Panning Audio – Panning for gold and the Pan LAW!

There is a function on the majority of mixers called Pan. Pan/Panning is controlled by the ‘pan pots’ which have an L on the left and the R on the right, with center being in the middle. This allows you to decide which side of a stereo track you want a signal to go too. Some mixers only record a stereo track and most cameras have 2 inputs that can be assigned as Left or Right.

Sound Cart Battery Solutions from Tracer

This is a new product called “12V 40Ah LiFePO4 Bespoke Battery Pack & Peli™ Case” from the Tracer Product Range.

This battery pack has a weight of 10.7 kg and is 300 x 249 x 196 mm. Charging time of 5-7 hours with recommendations to fully charge at least once every 6 months. Only loosing less than 0.5% power per day through self-discharge. Packed in a Peli case for brilliant protection. Charging life cycle of over 1,400 times. You can see how much power is left and if you need to recharge on the Inside by pressing one button.

Is there a real laser sound?

There isn’t actually a real world laser sound that exsists. This is because its a different spectrum than molecules in the air or other medium that sound energy is transmitted. This is why the sun doesn’t make a noise when it comes and goes behind clouds.

Volume and Amplitude: A deceptive relationship

The relationship between Volume and Amplitude seems obvious but has a hidden secret to many beginning in sound or working without full understanding. We all know that to turn something up means to increase both volume and amplitude and often I have heard some new directors say make it louder. Of course this isn’t their specialist field so of course they shouldn’t know everything.

The Most Expensive Mixer

If you have a search on Google Shopping for an audio mixer and put it highest to lowest pricing the most expensive mixer is around £21,000 which is around $35,350 at the date of this post. But is this the most expensive mixer?

First lets see what a longitudinal waves. These are waves in particles that move along the direction of energy that is created. This is easily shown with a horizontal slinky.

Definition: Baffle

A baffle is a partition that is used to prevent sounds passing into another space. Baffles are made of very absorbent material that diffuses all the sound energy before it passes through the baffle. Baffles are used to get rid of unwanted sounds or even reflections within a room. You could, for example, use several baffles in a big space to reduce reverberation time.

Definition: Backplate

A condenser microphone has a diaphragm and a backplate to measure differences in voltage that mimic sound pressure for sound reproduction. Inside the condenser is a fixed rigid capacitor element that has an opposite electric polarity to the diaphragm.

Does sound travel faster than light?

I love sound but unfortunately it doesn’t travel faster than 299 792 458 m / s. Only very complex physics can give you some answers to what is faster than light. Sound does have the ability to still go pretty quickly depending on its medium.

Best Sound Recorder

This is a very tricky post to write about because it’s going to be very subjective because I don’t know your circumstances. There are however different groups of features to consider for different aspects of work. So I will go through features of many mainstream recorders to help you decide what makes the Best Sound Recorder for you.

Long Takes With Boom Operators

Audio Bit Depth

Audio bit depth is the actual information in the audio file for each sample. The audio bit depth has different amounts of information, this is why you have audio bit depth of 8, 16, 24, 32, 48 and 64-bit. These respond to the quality of the sample. So the bigger the audio bit depth the higher quality the information is.
