Unit 48: Composing using Music Technology

Samples

A sample is a short audio clip that is taken from an existing piece of music in order to reuse is to create a new piece of music. To be able to do this, went on the internet to download various audio tracks, being songs and sound effects. Usually, samples will be manipulated by using various different techniques, such as; pitch shift/changing the key of the sample, reverse and time stretching. The Beatles are well know as being on of the first people to ever experiment and use sampling. This technique can be sound on their song 'Yellow Submarine'. A sample of a brass solo was added to the song, from Sousa by by George Martin and Geoff Emerick. The sample was added to the song and kept in the exact same key, cut into small segments and re-arranged to for a brief solo.
Here is a screenshot of the work completed today, above. We downloaded 5 sound effects tracks and imported them into Cubase and then continued to apply affects to them, such as; compression, pitch shift, reverse and EQ. Another way Samples can be used is by using them as a loop. This means to take a short sample and repeat it continuously, almost like creating a beat and also sound like they are played together on the same track. Percussion samples are commonly looped in order to create a drum beat from various different drum samples.

Reverse

I used this affect to reverse my samples. What this does is flips the track round and plays the sample backwards. Here is an example of me applying the reverse affect to a sample. 

Pitch Shift 

Pitch shift is when you take a sample and key the key or notes within the sample. This will enable you to make the sample sound high or lower than the original sample/track. Here is an example of me apply Pitch Shift to a sample, making it higher and then lower.

Time Stretch 

This affect makes the duration of the sample longer than the original. This affect can make the sample sound slower or fast the normal. Here is an example of the original sample when sped up and when slowed down.
