Car Recording: Ford Fiesta ST
Posted in Uncategorized on November 26th, 2010 by enosSomeone once told me that as sound editors one of the most important, if not THE most important, asset we have is our personal sound library as well as the ability and desire to collect original and unique sound content for each and every project we work on. Commercial sound libraries are a valuable part of our toolkit but we know that those same sounds have been used by numerous other people in many varying projects. Also, many of those commercial libraries fail to provide the amount of repetitions and varying performances of sound events we might need in our films. Therefore recording your own sounds for your work will ensure you are providing something unique and fully tailored to whatever project you might be working on.
When I started this blog some months ago my main desire was to share recording sessions and experiences with the wonderful online community of sound designers and enthusiasts who are so generous with their experiences and ideas. But for one reason or another I have not been sharing anywhere near as much as I would have wanted to and want to change that. More specifically, I want to document and share as many of my recording sessions as possible as I always find such posts of great interest!
Anyways, this week I had a vehicle recording session which is always a fun experience so with the blog in mind I remembered to take my camera with me and take some pictures and as well as record some video! The car we were recording was a Ford Fiesta ST which is the sport version of that car.
LOCATION:
One of the very important aspects of organising a sound effects recording session is choosing the right location! For those of us living in cities we are constantly bombarded by noise all around us whether that be traffic, airplanes,sirens,etc… We are so used to it that we often do not think about it but if you turn your recorder on and plug a microphone in you will be surprised as to how much noise pollution surrounds us! So though we could have gone further away from the city for an ideal location we decided to use a large empty car park near the Old Trafford stadium and the docks in Manchester. The location wasn’t ideal (especially on a Wednesday morning) but apart from the occasional seagull and some distant city hum the place was accessible and not too far away so we decided to use it.
EQUIPMENT:
For this session I brought my trusty Sound Devices 744T with my collection of microphones and a bunch of accessories like a boom pole, several windjammers, some cord and cable ties for attaching and securing microphones to the car as well as some fire resistant cloth to wrap the microphones in to provide protection to both heat and vibrations. However, as I have not yet acquired a mixer to go with the recorder which would give me access to four record tracks I only had the two onboard mic pre’s at my disposal meaning we would have to break the recording into smaller chunks and record several angles or events at a time and then reposition microphones for the next recording.
THE SESSION:
For the first part of the session we decided to begin with the onboard recordings of the vehicle. So to provide us with enough sonic variety that will allow us to tailor the tone and sounds of the car we proceeded to capturing the different sound elements and textures the car offered.
For the low frequency content of the vehicle which will provide a sense of weight and size we placed a microphone on the exhaust. In this occasion we decided to open the trunk of the car and attach a boompole onto the back seat. We then placed a Sennheiser 416 into the windjammer and pointed the windjammer to the exhaust but off axis to avoid the intense gusts of gas/air that come out of it and could distort our recordings. Other than the winds emitted from the exhaust the back of a car is a quite decent place to place a mic as the suction created by the car moving forward create a small space right behind the car were even at higher speeds the wind is not an issue!
For the next microphone we wanted to get the more mechanical and metallic grinding sounds of the engine. We originally tried to use a dynamic microphone that would handle the high SPL levels of the engine but the Shure SM57 we had brought was creating a weird whine so we decided to go for a small diaphragm pencil microphone (AKG Blueline modular with a cardioid capsule). This instantly sounded better so with the headphones on we proceeded to moving the microphone around different parts of the engine looking for a sweet point that would provide the cleanest and most interesting sound from the engine. It is important to listen to what your mic is capturing and not just at what your ears are hearing as ultimately what is getting recorded is what the mic hears and you might often be surprised as to what and how differently the mic sometimes captures sound. After finding the sweet spot we wrapped the microphone in a small fire resistant kitchen towel that would provide not only protection of contact and heat to the microphone but also absorb some of the vibrations. Also, after realising how much the vibrations of the engine were affecting the sound the mic was capturing we decided to secure the mic tightly to the engine and thus vibrate with the engine and not capturing the nasty sounds it was originally getting.
So you’ve heard the recordings of the engine and exhaust separately.On their own they sound weird and seem to be lacking but the idea is to record these isolated textures and sounds which when cut together in your project will provide the right blend of sounds required for each shot! Here is a listen to both sounds being played out once (exhaust on left engine on right) but gives you a good idea of how the sounds blend together to create a more complete and true sound.
We recorded all kinds of performances of these onboard sounds such as:
Start, Idle, Stop
Start.Idle,Pull Away
Approach, Idle, Stop
Constant driving at 1,000 RPM (30sec)
Constant driving at 2,000 RPM (30sec)
Constant driving at 3,000 RPM (30sec)
Constant driving at 4,000 RPM (30sec)
Accelerations & Gear shifts
Etc…
INTERIORS:
After recording the engine and exhaust perspectives we proceeded to record the same actions again but this time with a stereo recording of the interior of the car. Ideally these would have been recorded at the same time as the onboard engine and exhaust takes but due to a limitation in tracks on the recorder (only two mic pre’s) and not having another recorder available on the day we had to record separate. For the interiors I failed to take picture. We used a small diaphragm pair of condensers mounted on a T-bar and positioned between the two front seats!
TYRE:
We also wanted to capture the sound of the tire on the gritty asphalt so we set up for it. Instead of attempting to attach a microphone under the car near the tires we decided to boom it from the window!
EXTERIORS:
Finally after covering all actions from an onboard perspective we got out of he vehicle and recorded exterior driving and pass by’s.
So all in all a good and fun Wednesday morning
