Audio

 What do you think music brings to a film?

It is such an important part of a film because it is everything that isn’t said. It can lead, emote, it is a language that is global. You can watch a film where you don’t understand the language and you can get a sense of what is being conveyed by just listening to the music.  Apart from the music, the sound elements are setting up a world and shaping characters. Sounds provide the world beyond the screen, sets the scene and helps the director tell their story. I don’t think enough emphasis is put on sound and music but it is such a critical storytelling device. In some genres it is more important, as it is saying more than what is on the screen – think about a horror movie and how much is said with sound and music. The soundtrack really does cut through and stay with people, think of Jaws.

10  MOST  COMMON  AUDIO  MISTAKES  IN  DOCUMENTARY  FILMMAKING

Music as a Narrative Device blog below is from METRO SCREEN, September 30, 2015,  which I have copied below as Metro Screen is closing at the end of the year and I’m not sure how long the link will last.

BCMA Thinks: When Light Becomes Sound…

It’s a coincidence that I am writing about the idea of light becoming sound, while traveling in Northern Italy. Here, the natural light of the sky was the stepping-stone of many classical painters, particularly Caravaggio, known as the Godfather of Cinematography. But, I am not here to talk to you about that. This is about the light of sound…Let me explain.

How to Keep Your Sound Editor Happy (According to a Sound Editor)

With workflows getting more complex and post-production schedules getting tighter, it is more important than ever to have a clear and well-thought-out sound workflow in place. It is particularly crucial to establish this workflow with your sound editor well before postproduction starts.

7 Effective Ways to Give Your Characters Unique Voices

As a former studio script reader, I’ve read hundreds of screenplays — the good, the bad, and the ugly. A clear problem with most is that they fail to showcase unique voices for most of their characters. You could mix and match the character names with the dialogue and not see the difference — they are interchangeable and sound or read the same. And when they are interchangeable, that’s a clear issue when it comes down to a reader’s visualization of the script, as well as the potential casting later on in the development process.

AUDIO FOR VR

George the dummy head microphone, two microphones and does not do top, bottom, front and back very well and does not change the perspective.  Humans have two ears, notes the difference in levels between the ears, the difference in time that it takes for the sound to travel to the ears and position the sound based on those things. Giving the recording that sounds real, suitable for atmos, two track stereo. The head has been used in radio for many years and during an Opera on the steps of the Sydney Opera House, George was used for the orchestra inside in the concert hall.

The dummy head recording  is a method of recording used to generate binaural recordings. The tracks are then listened to through headphones allowing for the listener to hear from the dummy’s perspective. The dummy head is designed to record multiple sounds at the same time enabling it to be exceptional at recording music as well as in other industries where multiple sound sources are involved.

The dummy head is designed to replicate average sized human head and depending on the manufacturer may have a nose and mouth too. Each dummy head is equipped with pinnae and ear canals in which small microphones are placed, one in each ear. The leading manufacturers in Dummy Head design are: Neumann, Brüel & Kjær, Head Acoustics GmBH, and Knowles Electronics.

Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments. This effect is often created using a technique known as “dummy head recording”, wherein a mannequin head is outfitted with a microphone in each ear. Binaural recording is intended for replay using headphones and will not translate properly over stereo speakers. This idea of a three dimensional or “internal” form of sound has also translated into useful advancement of technology in many things such as stethoscopes creating “in-head” acoustics and IMAX movies being able to create a three dimensional acoustic experience.

The term “binaural” has frequently been confused as a synonym for the word “stereo”, and this is partially due to a large amount of misuse in the mid-1950s by the recording industry, as a marketing buzzword. Conventional stereo recordings do not factor in natural ear spacing or “head shadow” of the head and ears, since these things happen naturally as a person listens, generating their own ITDs (interaural time differences) and ILDs (interaural level differences). Because loudspeaker-crosstalk of conventional stereo interferes with binaural reproduction, either headphones are required, or crosstalk cancellation of signals intended for loudspeakers such as Ambiophonics is required. For listening using conventional speaker-stereo, or mp3 players, a pinna-less dummy head may be preferable for quasi-binaural recording, such as the sphere microphone or Ambiophone. As a general rule, for true binaural results, an audio recording and reproduction system chain, from microphone to listener’s brain, should contain one and only one set of pinnae (preferably the listener’s own) and one head-shadow.

SENNHEISER  The elegantly designed AMBEO® VR Mic has been developed in cooperation with VR content producers and fine-tuned through an extensive creators’ program with participants from across the audio and VR communities. The mic caters exactly to the needs of VR content creators, letting you capture the experience and spirit of any location enabling the listener to be immersed as if they were there.

Four mono channels, matrix into one mono in the middle, up down stereo and a left right stereo and front stereo.  When you move around the sound stays with the visual experience, losing the illusion.

AMBEO A-B format converter plugin.  The capsules of the Sennheiser AMBEO VR Mic deliver A-format, a raw 4-channel output that has to be converted into a new set of 4 channels, the Ambisonics B-format. This is done by the specifically designed Sennheiser AMBEO A-B format converter plugin, which is available as free download for VST, AU and AAX format for your preferred Digital Audio Workstation for both PC and Mac. B-format is a W, X, Y, Z representation of the sound field around the microphone. W being the sum of all 4 capsules, whereas X, Y and Z are three virtual bi-directional microphone patterns representing front/back, left/right and up/down. Thus, any direction from the microphone can be auditioned by the listener during playback of Ambisonics B.

MUSIC as a NARRATIVE DEVICE

Guest Blog from our partners Audio Network Director Brandon Faris knows the powerful effect music has on any production. Below he explains how he uses music to amplify the tone and emotion of a story.

One Sunday morning, Pastor Coots reached into a box and pulled out a rattlesnake. I was so transfixed by the rockabilly gospel playing that instead of being terrified, I was mesmerized. I was filming my short documentary Venom & Fire and at that moment I realized the power of music as a narrative device.

As a filmmaker, I have devoted much of my time to commercial and documentary work. Sometimes I feel confined by the script or testimony. Music, however, gives me the ability to transform content, allowing me to tell the story that’s in my mind’s eye.

After selecting the right music, I look for space in my edit where it will naturally push the story along. Constant music throughout an edit can make a video feel pre-fabricated. Think of music as a breath, knowing when to inhale and exhale. I use silence as a mechanism to contrast with my tracks – it helps build an emotion or transition to a new idea. When you mute the dialogue tracks, you should be able to hear the story arc in the music. This is how you know you have selected music that is working hard to support your story. When done right, the viewer should barely notice the music because they are consumed by the story.

I have developed a few exercises that help me select music with a purpose and not out of a necessity that I’d like to share.

Lose yourself in the music

I’m not talking about getting high on recreational narcotics and staring at the cosmos, I’m proposing that you let go of your personal music bias and open yourself to the story. Dive deep into the culture of your subject, even if it goes against anything you would publicly admit you have listened to.

While making Hoofer, a short documentary about a tap dancer, I selected cheesy teen pop music for a dance montage. I don’t usually listen to teen pop house, but it brought the scene to life and our film was awarded Best Music at the International Documentary Challenge.

Listen to your surroundings

When you are on set, it’s easy to be consumed by the visuals. In an industry obsessed with the next big thing in video resolution, filmmakers often omit the importance of sound. As a documentary filmmaker, I’m always listening to the room. Something playing in the background could be an indicator of the general tone of your subject: consider it a gift.

While filming Venom & Fire, I asked the daughter to sing her favorite hymn for me. I recorded her and captured what would become the theme for the film. By setting it against simple Dobro slide chording, it came to life.

Trust your emotions

Music has the power to shape your mood. The human experience has a broad range of emotions that you have been experiencing your whole life. Fear, joy, depression, and angst come naturally – so will the music. When you are selecting tracks to support or drive a story, allow yourself the space to feel the music. When you share a rough cut with people, ask them how it made them feel.

In an attempt to inspire my native Cincinnati, I carefully selected tracks for my short film Art & Craft: A Tale of Beer and Brushes. At the premiere, over 500 hometown supporters erupted into applause and you could feel the sense of pride in the room. With the wrong music, it would have just been some pretty pictures and an interesting interview.

As I think about my experience that day in the hills of Appalachia, I recall the charismatic sights and sounds. Although the people and stories were intriguing, it’s the music that haunts me. I witnessed something mystical, beautiful, and I will never forget what that sound looks like.

Brandon is the director of LEAPframe, a Cincinnati-based video production company.

SOME THEORY

KhanAcadmey on Amplitude, period, frequency and wavelength of periodic waves

Making Waves:  the visualisation of sound is  shown as a wave.  When a loud speaker vibrates it moves the air that generates sound waves.

Link on Waves

Amplitude:  how loud a song seems will depend on it amplitude and is measured in decibels or dB.

Wavelength: the distance between wave peaks or troughs

Frequency and Period: the frequency affects the pitch of sound and is how many times a wave passes a given point in a second or th timing of the waveforms. It is measured in Hertz Hz, kHz.

Kilohertz (kHz) to hertz (Hz) conversion calculator

Period is how long one cycle takes in seconds, could be 0.25 of a second.

Resonance: where a wave is reinforced at the right time.  The resonance frequency of a container is reached then the sound will become suddenly louder, like when you run your finger around the rim of a wine glass.

Tacoma Narrows Bridge Collapse “Gallopin’ Gertie”

Sample Rate:  how many times a second it is sampled, like video is frames or the speed at which the samples are collected. If the sound is sampled at more than twice the frequency contained in the sound you capture all the sound. CD’s = 44.1 kHz or 44,100 samples of music every second, professional audio at 48 kHz such as video. Can go as high as 96kHz, some people are capturing at 88.2 kHz which is twice 44.1 kHz and can cut in half for a CD.

Sample Rate Comparison

Bit Depth: the number of bits used to store the sound, 8, 16, 24 or 32-bit float. This determines the dynamic range of the file, the amount of information or sound levels that can be stored, the hight the bit depth the more information or dynamic range.

dB: how loud 2 sounds are with respect to one another, referring to the ratio of one sound level to another. The maximum sound level for a piece of equipment is often designated as 0dB.

VU Meter is a device displaying a representation of the signal level in audio equipment, averaging out peaks and troughs of short duration and reflects more the perceived loudness of the material.

Distortion:  is usually the alteration of the original wave shape and thus the sound.  A typical example is when the sound wave has been clipped when the level is too high.

Speech audio sample of clipping caused by poor amplifier quality or selection

Compression:  or Dynamic range compression, also called audio level compression, in which the dynamic range, the difference between loud and quiet, of an audio waveform is reduced.

File Formats: can be unchanged or compressed by either removing some of the audio or by cleverly merging sounds.

  • uncompressed: e.g. wav, diff,  BWF
  • lossless compression file formats: e.g. wma, m4a, flac, ape, WavPack, Monkey’s Audio, ALAC

A lossless compressed format stores data in less space without losing any information. The original, uncompressed data can be recreated from the compressed version.

  • lossy compression file formats: e.g. mp3, verbs, AAC

Lossy compression enables even greater reductions in file size by removing some of the audio information and simplifying the data.

An early example of this was on the soundtrack Tubular Bells by Mike Oldfield, in which up to 90 overdubs were made to allow 1 person (Oldfield) to seem to play a large number of instruments simultaneously. Tubular Bells was largely responsible for the early success of Richard Branson’s Virgin Records.

History of Multitracking  is a process where the tape is divided into multiple audio tracks parallel with each other. Because they are carried on the same medium, the tracks stay in perfect synchronisation.

MEG-H  allows for Scene-, Objects- and Channel-based audio formats to be transmitted simultaneously, eliminating the need for multiple mix formats such as stereo, 5.1, 7.1, 7.14 surround sound.  Scene-based audio is a loudspeaker agnostic format that is designed to adapt to the local loudspeaker geometry and acoustic landscape to offer optimal immersive sound playback in any location. MPEG-H Scene-based audio can deliver 3D sound to a variety of devices such as smartphone, tablets, STBs, speaker bars, smart TVs, AU receivers and more. Scene-based audio is said to work well for live recording because it captures a representation of the entire sound scene without requiring a human soul mixer. Also allowing listeners to interact with and personalise their audio experience.  Listeners can combine audio objects like dialogue and multi-lingual commentary with scene-based audio or manipulate the audio point of view. Object-based audio, meanwhile, allows content creators to nominate ‘objects’ within a mix-individual sounds such as cars, gunshots, aircraft etc – and specifically where those sounds objects should originate and how they should move Dolby atoms in an example of an object-based audio scheme. MPEG-H works for both live capture and for recorded content.
