Critical Introduction: Soundscape

In his natural sound design "Metropolis", George Whale intends to send his listeners into the industrial world of business and transportation. No longer looking for the ordinary, the listeners can still relate to the design through its incorporation of natural sounds in an unnatural world in what George Whale hopes will be a therapeutic experience. This projects initially endeavours to connect our acoustic relationship with a city and an almost dystopian future over run by machines and technology. The uses of natural sounds being manipulated for an unnatural setting is similar to the work done by Ben Burtt for his sound design of the Star Wars saga, he believed this would technique would create a subliminal bond between the spectator and setting through the uses of familiar sounds. His methods of practice along with David Sonnenschein’s theories on sound design inspired Whale into sourcing ground sounds and subtle sound to create the foundations of his low-fi soundscape. By using a minimal amount of sound elements, the piece becomes more emphatic. According to Sonnenschein’s theory of sound design, stating “sometimes you can get the most impact with the least number of elements, allowing the audience to be more participatory by letting them fill in the gaps with their minds, as opposed to handing them a full plate” (Sonnenschein 2001)

The 2 Main Types of Microphones

The 2 Main Types of Mics


Condenser Microphones


These types of microphones have a much greater transient and frequency response, which is the ability to reproduce the pace of the sound. They're most commonly found in music studios and tend to have a louder output, but are much more sensitive to loud sounds. Their sensitivity to low sounds means that they're more fragile than their counterpart - the dynamic microphone. 

Condenser microphones need 'phantom power' which in usually supplied by a mixing board in a studio which tends to have a switch with '48V' on in, which refers the the 48 volts of power being supplied to the microphones.

Condenser are generally much more expensive than dynamic microphones but cheap ones can be bought to, although they may not be of high quality. There tend to be two main types of condenser mics which are labelled on the size of their diaphragm.

Large Diaphragm Microphones (LDMs)

- Used mainly for studio vocals and instrument recording.

Small Diaphragm Microphones (SDMs)

- Used for sounds that are solid and have a wide frequency
- Very sensitive to transient noises like 'P' and SH' sounds that cause distortion.



Dynamic Microphones



These microphones are more rugged in comparison to condenser mics. They're resilient to moisture and abuse which makes them good for onstage performances. Unlike the condenser microphones, dynamic mics do not require their own external power supply however, their sound quality is never as accurate. This could be due to their limited frequency response. Although, this gives these microphones the ability to withstand high sound pressure levels. 


Directional Microphones

Different types of microphones pick up sound is various way because of the audio patterns formed by the way the sound travels. Understanding these patterns gives you a better understanding of what microphone you'll need in your given situation. These patterns are:

Omni-Directional

A good all purpose microphone which gathers a wide range of sound from all directions. It is great for picking up all voices in debates or group discussions. For a good quality sound, this microphone must be held close to the source. These types of microphones are found in camcorders.

Omni-Directional Audio Pattern

Cardioid 

This pattern is in someway, heart-shaped (hence the name). It is typically used to pick up sounds that are sourced from the sides of the microphone and also behind it. Handheld microphones used in news interviews usually use microphones that pick up this audio pattern

Cardioid Audio Pattern


Uni-Directional

Used mainly in shotgun microphones, this audio pattern has a great focus on a specific sound to block out an ambient noise. This is a great microphone when you're trying to pick up one sound amongst many such as picking up one persons voice in a discussion.

Uni-Directional Audio Pattern



What is the 'Proximity effect'

The Proximity Effect

When a sound source gets close to a cardioid microphone, the bass frequencies in the sound can be boosted/exaggerated making a more 'boomier' bass. What are the effects of this?

Effects

Singers often used the proximity effect without realising! Just by bringing the microphone closer to their lips, it gives the sound a more intimate tone. However, depending on how much the sound is being projected, the bass boosting of the proximity effect can be bad as it can make words harder to understand on the ear and if the microphone is continuously moved from the sound source, it can give the sound and unnatural feel.

To avoid proximity effects, stay between 6-12 inches away from the microphone. This prevents the diaphragm of the microphone being overloaded, therefore giving the sound and unarticulated feel.

Uses

This effect would come in use for my interview part of my project as I shall be using a similar microphone to this when I record my interview in the studio booth. I shall be wary not to get to close to the microphone to give my voice as well as my interviewee more clarity in what they're saying. Also, I will try not keep myself in the same position throughout the interview so the sound of my voice does increase in volume or bass from moving closer in towards the microphone or vice versa



EQ and its effects

Equalisation

Equalisation or EQ for short is the process of altering the frequency response of a sound. The most familiar type of EQ is the treble/bass control.

TREBLE - Adjusts high frequencies
BASS - Adjusts low frequencies

It is used to correct sounds which sound unnatural, eliminate unwanted sounds and make certain sounds more prominent and reduce feedback. There are a few types of equalisation, such as:

BELL EQ - This boosts the range of frequencies focused around a certain point. This point gets effected the most by the EQ whereas the frequencies further from this point are less effected.

PARAMETRIC EQ - This uses bell EQ but have a significant advantage of being able to select which frequency is being adjusted. These equalisers can be found on guitar and PA amps.

SHELVING EQ - This type of equalisation boosts the frequencies within the sound recorded to a certain frequency causing a 'shelf' in the frequency spectrum

GRAPHIC EQ - Depending on the number of sliders you have dictates how much control you'll have over the frequency spectrum of the sound. This way you can manipulate a certain area of the spectrum


Terminology

CUTOFF FREQUENCY The frequency at which a high or low frequency EQ section starts to take effect. Also referred to as turnover frequency.

SLOPE The rate at which a high or low frequency EQ section reduces the level above or below the cutoff frequency. Usually 6, 12, 18 or 24dB/octave.

PASS BAND The frequency range that is allowed through.

STOP BAND The frequency range that is attenuated.


FILTER An EQ section of the following types:

HIGH PASS FILTER A filter section that reduces low frequencies.
LOW PASS FILTER A filter section that reduces high frequencies.
BAND PASS FILTER A filter section that reduces both high and low frequencies.
NOTCH FILTER A filter that cuts out a very narrow range of frequencies.

GAIN The amount of boost or cut applied by the equaliser.

Q How broad or narrow the range of frequencies that is affected.

SWEEP MID A middle frequency EQ section with controls for frequency and gain.

PARAMETRIC EQ An EQ section with controls for frequency, gain and Q.

GRAPHIC EQ An equaliser with a number of slider controls set on octave or third octave frequency centres.

BELL An EQ with a peak in its response.

SHELF A high or low frequency EQ where the response extends from the set or selected frequency to the highest or lowest frequency in the audio range.

Reverb and its effects

Reverb

Reverb is short for reverberation is when a sound is reflected, causing a large number of reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space - this could be furniture and people, and air.

Lloyd, Llewelyn Southworth (1970). Music and Sound. Ayer Publishing. p. 169.

From my A-level studies of physics, I understand that sound waves are longitudinal waves that the vibrations of sound particles travel parallel to the direction of wave motion. Sound waves can bounce backwards and forwards in many directions, even when you're speaking to someone directly, others can still hear you but hear a more 'died out' sound.

An example of reverb is when you speak to someone, you project sound waves at the listener as well as other directions. The waves that aren't directed at the listener reflect of the surroundings such as walls, furniture etc. and when the waves do reflect, two things happen:

1. The waves lose energy, causing the sound to dissipate.
2. The waves take longer to travel the listener's ears.

These reflections can be referred to a series of 'fast echoes' which differ depending on the environment the sound is within. For instance, in a empty church hall, reverb is at its most pronounced - However, the more people inside the church hall, the more the reverb is reduced as the people absorb the sound.



Effects of Reverb


There are 3 possible reasons why you would put the 'reverb' effect on a sound:

1. To create special effects for certain sequences such as dreams or flashbacks

2. To restore the natural sound as the listener would expect to hear it. What this means is that if your recorded sound is in a low reverb environment such as a studio booth, you may want to add reverb on it to make the unnatural sound of the studio seems more natural.

3. To enhance the sound - especially dialogue. Reverbs fills out the voice of someone and can help smoothen minor vocal fluctuations so they aren't as obvious to the listener.


Here is a good example online of the effects of reverb on drums.

http://www.mediacollege.com/audio/reverb/examples.html


Uses of Reverb for Project


Reverb can be incorporated in both my soundscape and my interview. I think it will definitely needed to be used for interview as the interview shall be taking place in a studio booth so by adding reverb it will give a more natural sound to my interview. As for my soundscape, some on the sound clips I have recorded could have the reverb effect put on it as my sounds vary in terms of what environment the sound was recorded in. For instance, some of the sounds I have recorded take place outside such as on the beach or in Brighton town. Others have been recorded inside or in more of a closed environment. I believe it is important to understand what reverb is and how it effects sound as making a sound that gives a more natural feel to the listener can only heighten and improve the sounds you have recorded...if used correctly.

PROJECT #2: Interview


Aim/Objective:

- You are required to submit a three-minute edited interview with a single individual of your choice for presentation on local radio. You must choose someone who you feel has something to say to the Brighton & Hove community.

You must also submit a typed, 500 word, statement which critically introduces your submitted project work locating it contextually, theoretically and aesthetically.





I have decided to interview one of my sister's friends who she lived with during her time at university. His name is Fred Cassman, he owns and operates his own e-cigarette business which he started many years ago whilst he was studying at university. I thought this matched the criteria of the objective as the electronic cigarette business has in somewhat 'flourished' in the last 10 years and the fact Fred has now opened up a store for his business in town means he must have some impact upon the community. 

From listening to the radio from a young age, hearing countless interviews in various formats I understand that the most engaging type of interview contain:
- A gripping subject matter, relevant to society.
- They sound more like a conversation rather
- Have a fair and unbiased outlook on the subject matter

I aim to incorporate these aspects into my own project.





Securing the Interviewee:

Once I had chosen my subject, I enquired with my sister as to whether she would ask Fred if he would consider having an interview with me about his e-cig business and he willingly agreed. I then got in contact with him over facebook and informed Fred about where the interview would take place, how long it would be and what sort of interview this was going to be. I thought it would be best if the interview was recorded in a studio booth on campus as this was going to be a informative speech package in the form of an interview, so I wanted there to be clarity within the dialogue, thus having no ambient sound distraction and pure concentration on the dialogue. When we both came to a conclusion of where and when the interview would take place, I then had to construct interview questions for the interview and research the topic area of discussion - electronic cigarettes.


Research & Planning:

By this stage, I knew little about the electronic cigarette. I used to sell a form of electronic cigarettes in the supermarket I used to work in and I knew that they were a way of helping smokers to quit tobacco/nicotine by smoking a replication of cigarette smoke, almost like a vaporiser pen and I knew you could get them in different shapes and sizes and flavours. But I had no concrete understanding of what e-cigarettes are and their impact on people and the community.

So I researched the electronic cigarette and found a few interesting articles and interviews online such as:

1. E Cigarette Uptake & Marketing - A Report Commossion by Public Health, England

https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/311491/Ecigarette_uptake_and_marketing.pdf


Notes:


- E-Cigarettes are battery operated devices that aim to simulate combustible cigarettes. They do not contain tobacco - they operate by heating nicotine and other chemicals into a vapour that is inhaled.

- The role of the tobacco industry in manufacturing and promoting e-cigarettes, while continuing to sell conventional cigarettes, has been questioned.

- There are concerns about the current marketing of e-cigarettes and whether that marketing may appeal to children.

- E-Cigarette market is estimated to be worth £91.3million a year (3) It increased by 340% in 2013 to reach £340 million by 2015.

- In the UK, there are an estimated 1.3million e-cigarette users.

- The first e-cigarette on the UK market to be available as a medicine will be manufactured by a tobacco company.

- The marketing may appeal to children as well as adults. They are marketed as a cheaper, healthier alternative to smoking and also positioned as socially attractive and part of a rapidly growing trend.



2 . Whether they're called 'e-cigarettes' or 'vaporisers' the market is heating up!

http://www.theguardian.com/business/2014/jun/26/e-cigarettes-market-vaporisers

This article, written by Rebecca Smithers for the Guardian this year goes onto discuss E-cigarettes marketing and industry and how the merging of tobacco companies in the e-cigarette business are impacting the business.



3. An Interview with an inventor of the E-Cigarette Herbert A. Gilbert


This article helped me come up with a structure for my interview and how even though I'm running the interview, the vast amount of talking shall come from my interviewee

3. An Interview about the E-Cigarette with Dr. Jonathan Foulds

Constructing the Interview Questions:

Now I had more information about the e-cigarette business and how they worked, back up with stats and statistics, I could now construct an interview with questions that could trigger a debate with Fred as well as to informing the listeners. I knew that the speech package I was constructing could seem a bit patronising to certain members of the audience who may already be aware of the e-cigarette business and how it's developed, but the point of this speech package was to inform the uninformed. On the other hand, I wanted this speech package to inform the listeners about what an e-cigarette is and how they have impacted Fred's life and others around him.
I wanted this piece to be personal to Fred, rather than a broad discussion of the e-cigarette industry on a national level. I constructed a script for the interview which I sent to Fred a couple of days before the interview so he was aware of what he was going to be asked to prevent as much stuttering and pondering in the interview when it came to the informative questions I had planned. Here are the questions I have planned to ask him:


Questions:

1.    So Fred, tell us a little bit about e-cigarettes, what are they and how they operated


2.    How you first get involve with the e-cigarette business to eventually having a store in Brighton?

3.     E-Cigarette usage in the UK has tripled to two million in the last two year. Why do you think they’ve become so popular?

4.     I’ve seen e-cigarettes come in all shapes and sizes, some looking exactly like a cigarette and others appear to look like ink pens or tyre gauges? I guess what I’m trying to get at is how do you know if someone’s using an e-cigarette?

5.    There over 10 million adult smokers in the UK, so it’s a huge market, It’s also very expensive here, with cigarettes costing up £8 for a packet of 20. How much do e-cigarettes cost?

6.    What impact do you think you’ve had in the community since opening you store in Brighton?


7.    There are concerns about the current marketing of e-cigarettes and whether that marketing e-cigs may appeal to children. They are marketed as a cheaper, healthier alternative to smoking and also positioned as socially attractive and part of a rapidly growing trend according to a report commissioned by the Public Health. What do you make of this Fred? Do you think the way e-cigarettes are advertised promote smoking?

8.    What do you make of the health issues surrounding e-cigarettes? The big question many of us ask about them is, are they safe or harmful?

9.    Do you believe they’re the first step to stopping smoking?


10. Some analysts argue that the entrance of big tobacco firms into the industry sector blurs the line between e-cigarettes and conventional tobacco, thus making e-cigarettes a gateway for users into actually smoking… Do you think this is true?

11. How do you feel about the big multinational tobacco companies monopolising on the industry?

12. Do you have else you want to say to us before we run out of time?


I thought having 12 questions would be more than enough questions to cover the 3-5 minute window of the interview and that not all these questions would even get asked as some could trigger a more lengthy answer for discussion or that Fred may give a simplistic answer. 




Interview Plan

As my interview for a radio show is a speech package to inform, I'll need to put my interview into context for the listener. Therefore, I shall open the piece on stating statistics of the e-cigarette industry and how popular they have become in the UK, then I'll introduce my interviewee. If my piece is going to be more personal towards Fred, I also need to explain to the listener who he is and his affiliation with the e-cigarette market before going into the discussion about the positives and negatives of the e-cigarette market and how Fred's business starting from deliveries from his bedroom to opening his own store in Brighton. Once the core piece of the interview is done I shall also need to add an outro for my piece which I want to conclude the piece and a poignant rhetorical question which will leave the listener thinking about the speech package they just heard, making it a more memorable piece. It may even be more emphatic if Fred ended the piece.






Post Production of the Interview


Now that the interview was recorded, I would have to edit the piece to cut out stuttering and pondering between questions as well as giving the dialogue certain sound effects to give a more clear and natural feeling interview. By using Adobe Audition I was able to put on effects such as reverb and vocal enhancers to the interview which gave the interview my desired sound effect. Since the interview I had recorded was over 10 minutes long, I would have to cut out a big majority of the interview to keep within the project criteria as well as insuring that the transition was fluid between each question. Some of my questions had to be re-recorded as Fred's voice sounded a lot more dominant compared to mine so this needed to be balanced. As this was recorded in a voice over booth, I added a parametric equaliser effect which will adjust the frequencies within the interview to a centre frequency. Thanks to Mike Russell's video tutorials on YouTube (https://www.youtube.com/watch?v=6x__NthInRs) I was able to manipulate the audio into a more professional sounding speech package. I also re-recorded my own questions in the interview so my questions were moulded around his answers and also gave more voice more depth and dominance than the first recording as I was sitting a little further away from the microphone. Many cuts of stutters were also taken out from the piece which gave the interview more pace.





Conclusion

I enjoyed this project. It pushed me to use technology that I had never used before and also to communicate and contact with people which I've never met. Fred was a great person to interview, he clearly had a sound knowledge on the field of electronic cigarettes and it was a pleasure to go for a coffee with him after the interview where he offered me a possible weekend job for his company! Editing the interview was the most tedious part of the project as it consume a lot of my time find the right effects for the sound piece and of course cutting down the feature time. If I could improve any aspect of my interview it would be to add an outro to summarise the speech package/interview or possibly to of got Fred's business partner involved in the interview as well which would give the interview more depth of debate. In regards to what I aimed for, I believe my piece was engaging and relevant to everyday life in the society we live in. It's debatable that my interview had an unbiased outlook, however my piece became a more informative piece which promoted Fred's business. I believe this project was successful and has taught me a lot of interview skills as well as giving me confidence with sound recording equipment and software.
