Edit sound

Business Sectors (Suites): Post Production
Developed by: ScreenSkills
Approved on: 01 Jan 2017


This Standard is about editing sound material to meet production requirements. It involves assessing the material to decide what sort of edit should be used, and dealing with difficulties in making the required edit. It is about selecting appropriate edit points, making technically accurate edits, assessing finished edits, and completing them by the deadlines you have been given. You may sometimes be working to tight deadlines and under pressure. This Standard should apply to anyone who is involved with editing sound.

Performance criteria

You must be able to:

  1. ascertain the technical, creative and commercial requirements for

    sound editing from reliable sources

    type of edit to be made

    1. explain to relevant people the implications to original material of

    recording with data reduced compression techniques

    1. suggest suitable solutions to decision makers to combat any

    difficulties in completing proposed edits

    1. organise tracks and materials in an appropriate manner to carry

    out your work

    1. select edit points which create required transitions and offer the

    greatest potential for meeting client or production requirements

    1. select edit points that achieve required duration, rhythm, pace,

    information and background; and when applicable support


    1. use an editing style that is appropriate to the material

    2. retain any required synchronisation in the edit

    3. select and mark edit points in an accurate and clear way

    4. use a type of edit which is appropriate to requirements

    5. make edits which are technically accurate, clean and artistically


    1. confirm that edits made meet client or production requirements

    2. complete editing within agreed deadlines and budget

    3. mark any trims and unlabelled source material in line with

    company systems, and store them so that they can be recovered

    if required

    1. confirm that non-volatile storage of edit data is kept up to date

    2. confirm that necessary back-ups are maintained, to preserve the

    integrity of audio and data

    1. confirm that original material is protected

    2. produce accurate and legible paperwork and labelling in the

    format required

    1. maintain security for files and other materials in line with company


Knowledge and Understanding

    1. the material to be edited, what the editing requirements are, and

    what types of edit are possible

    1. the legal limits and standards for sound files for distribution and

    delivery especially in relation to loudness, immersive audio and

    metadata and how to work creatively within them

    1. the importance of audibility of dialogue especially with regards to

    the impaired hearing of an ageing population

    1. effective strategies to enhance dialogue audibility

    2. where to acquire source materials

    3. the timescale and budget for the edit

    4. the documentation and format requirements

    5. any synchronisation requirements and their implications in the

    production process

    1. the implications for editing where sound supports picture

    2. edit point selection criteria, and how they are used to identify edit


    1. criteria for assessing the technical and artistic effectiveness of


    1. degrees of editing difficulty, and how to recognise and resolve

    1. common data reduction formats and techniques

    2. the implications of using and dealing with data-reduced

    including impedance, attenuation networks, phantom powering,

    and signal-to-noise ratios

    1. the relevant principles of acoustics and how they apply

    2. the performance characteristics of microphones including: size,

    weight, maximum output level, pick up pattern, sensitivity and

    susceptibility to handling noise

    1. the characteristics of amplifiers and loudspeakers
