Task 1 Discuss these questions:

  1. What do you think a drum machine does?

  2. What do you think these keys refer to on a drum machine?

kick snare closed hat open hat

Task 2 Match each text on the following page to the correct step in the process of

sampling and reproducing the sound of a drum digitally.

с

(I

When the drum pad is pressed, the stored information is decoded and produces an electronic signal.

The signal is sliced into many 'samples', each one a snapshot of the strength of the signal at one particular moment. This information is converted into binary code and then stored in the machine's memory. When the drum is hit, it produces sound waves.

The signal is turned into sound waves through an amplifier, and the drum sound is heard.

The sound waves reach the microphone and are converted into an electrical signal.

Reading 1 Recognizing topic

A useful reading skill is skimming, which is to be able to recognize quickly which part of a text deals with a particular topic. Paragraphs usually deal with one topic or sub-topic.

Task3

Read through the text quickly to find which paragraphs describe:

a analogue recording

b what quantize means

с the advantage of digital sound

d what happens when one of the drum buttons is pressed

e how sound samples are stored in a drum machine

f in brief what the machine does

para

A drum machine stores sound which has been recorded digitally. The machine's read-only memory (ROM) stores sounds which have been pre-recorded from the original instruments. By pressing the pads which correspond to particular sounds, you can create your own songs and rhythms without ever touching a drum kit. Each sound can be played at any speed and in thousands of different combinations.

When we hear sound, our ears are detecting changes in air pressure. These changes in pressure, which might be caused by vibrating a guitar string or banging a drum, are sound waves. To record these, the wave patterns in the air are converted by a microphone into electrical signals. The voltage and frequency of these signals correspond exactly to the fluctuations in pressure of the original wave. This is called analogue recording.
