What is digital sample manipulation?
This is when you control a sample in different ways to change how it originally sounded.
Digital: discrete signal, represented as binary (0s and 1s).
Sample: a piece of recorded audio.
Manipulation: to control or change something.
What could you use a sampler to control?
Loop: repeat a sample until they key is released.
Truncate/Trim: change the length of the sample.
Pitch Map: speed up or slow down the sample to change the pitch.
How could you manipulate a sample?
Audio effects plugins.
Time stretch.
Transpose.
How could you use plugins to manipulate a sample?
Use a reverb to space the sample in a different space.
Add distortion to change the tone of the sample.
Use EQ filters to make the sample sound further away.
Use EQ filters to make the sample sound as though it is coming from a small speaker or headphones.
What is time stretching?
Time stretching can be really useful when working with effects library samples.
Often the sample will not be synchronized with the action on screen.
Subtle amounts of time stretch to make a sample slightly faster or slower can be really effective.
What are spot effects?
Sounds which are generated to enhance particular moments in a form of media.
This could be to add impact to an action on screen or add emphasis to text on screen.
We can use musical instruments to create spot effects.
What are environmental sounds?
The background sounds of a place or space.
Why must environmental sounds recordings be long?
Our brains are able to notice patterns very easily. For example:
A five-second recording of an environment looped, would become very repetitive.
Our brains would very quickly recognize that this was not real.
This could ruin the illusion of realism.
What could be the potential problems with trying to record long environmental sounds?
Sounds that are not desired for the recording are recorded.
These sounds cannot be removed.
Requires portable equipment.
Equipment that requires a power source.
Requires travel to specific locations.
If it is windy day, this can cause the microphone to distort leaving the recording unusable.
Why are environmental sounds best recorded in stereo?
Because it will give the listener a sense of physical space.
This means that you will use two microphones to capture the sound.
The most appropriate stereo microphone technique would be XY coincident pair.
