too high a level causes distortion The mixer also has EQ (equalization) controls which adjust bass and treble The output form each channel is fed to a track on a multitrack tape recorder After the music has been recorded on the multitrack, it is mastered down This means that it is fed back through the mixer to adjust the levels of vocalist and instruments in relation to each other At this time, effects can be used to alter the sound One of the most common is reverb (reverberation) which can made the music sound as if it was recorded in a very large building or a very small room The edited sound is recorded on a two-track mastering machine to produce a master tape The master is then used to make records, cassettes, CDs or MDs Language studyDescribing a process In English the passive often used to describe processes Study these examples: Each instrument is recorded Speccial effect are used Copies can be made The passive is made using the verb to be (be, is, are, ect) and the past participle of the verb Most technical verbs are regular so the past participle is made simply by adding –ed ( Example 1) Watch the spelling of the past participle of verbs like control (controlled ) and use ( Example 2) The passive infinitive is used in the same place as ordinary infinitives, for the example after verbs like must and can ( Example 3) Task 3: Complete this summary of how to make a recording, by putting each of the verbs in brackets in the correct form Each instrument is recorded using a microphone The sound are fed to a mixing desk The recording level are controlled and the EQ is adjusted by the sound engineer The output is recorded on a multitrack The sounds from the multitrack are mastered back through the mixer The tape is remixed until the musicians are happy with the sound Special effects can be added on the mixing desk Theremixed tape is mastered down to produce a master tape This can be used to produce copies in many different formats Task 4: Listen Task 5: Word study One way of remembering new word is to group them into topic sets according to their area of meaning The words in Task are all concerned with making a recording They fall in to three topic sets: people, olace, and equipment Make your own topic sets for other units in this book Place Studio People Musician Sound enginner Vocalist Equipment Master tape Microphone Multitrack recorded Mixer Task 6: Writing Describing a process There are many stages involved in the production of CD discs The more important ones are shown in fig.1 You can describe the whole process of CD production: Fistly, a blank perspex disc is grinded and poslished to optical flatness Next, it is washed and spin-dried It is then coated with a thin layer of photoresist and cured in an oven After that, as the disc is revolved, a laser beam is used to mark audio information pattern on its surface This process is known as ‘cutting’ disc The photoresist is then developed and etched to produce pits in the disc’s surface These pits represent the digital audio pattern The disc is then given a thin silver coat to make it electrically conductive Next, the electroplanting is used to make a series of positive and negative copies of the master disc The final negative copy is used to make a large number of indentical CDs The surface of CD containing the pits marks is then coated with a 10 mm layer of aluminium, followed by a protective layer of plastic Afterpunching the centre hole,a label is applied and the CD is packaged
