Intro To Media Tech Lecture 10

Front 1

Audition:

Back 1

Industry standard software; many parallels with Avid Pro Tools

Front 2

Wave form editing

Back 2

Manipulating audio wave forms by cutting and pasting sections and/or applying filters and effects

Front 3

multi-track editing

Back 3

combining multiple wave forms into multi- track compositions

Front 4

basic waveform editing

Back 4

removing sections, artefacts;

extend or shorten a musical backing track;

add new sounds

Front 5

Zero Crossings

Back 5

if you delete a section where there is a non-zero crossing there will be audible clicking

Front 6

EQing

Back 6

adjusting different frequencies to exacerbate sounds

Front 7

graphic equaliser

Back 7

boost or attenuate frequency bands in a track

Front 8

graphics eq ad/disad

Back 8

ad: simple to use

disadvantage: lacks precise control

Front 9

parametric

Back 9

allows you to boost/attenuate specific parts of the signal, using bands/stages

Front 10

Stages

Back 10

Gain (amplitude)

Frequency (centre frequency)

Bandwidth (Q)

Front 11

EQ-ing

Back 11

involves changing amplitude of certain frequencies, often results in change in amplitude

remember to adjust gain where you have applied EQ effects

Front 12

Audio Restoration

Back 12

Removing imperfections in recordings;

background noise,

pops and crackles,

hisses and mains hum

Front 13

Constant background noise

Back 13

can be removed by identifying said background frequencies and attenuating them

Front 14

Noise Reduction tool

Back 14

sample region that should be silent;

remove frequencies from said sample

Front 15

One-off Artifacts

Back 15

these can be identified and deleted from the spectogram

Front 16

Multi-track editing

Back 16

combining multiple sounds together into a composition

Front 17

Frequency masking

Back 17

instruments often mask each other if their in same frequency rang

Front 18

solutions

Back 18

Pan each to different speakers;

Use eq to mix to decide which sounds occupy which frequencies
