On the other hand, a suspense scene permits the use of very low sound levels. Generally, for dialogue an effect can be obtained not by the absolute level of the sound but by the contrast: a burst of sound will be much more effective if it is preceded by a passage at a moderate level. This trick is well known amongst cinema “mixers"- the level is lowered before a forte. When should compression be done? a) Recording intended to be transferred on to a disc. The signal-to-noise ratio of the modern disc is excellent. but it is necessary that the noise level of the tape should not be transferred. If a compression is decided upon, it should be done at the original recording. otherwise an increase of the pianissimi will also increase the sound level of the tape noise. it is difficult to use the complete dynamic range of the recorder without the risk of exceeding the maximum level when a fortissimo is produced. For this reason, it is prudent to work simul- taneously with two or three tape recorders in parallel. but whose input sensitivities are varied by a few deci- bels. The tape which has been recorded at the highest level, but without the maximum level having been exceeded. will be the one used for playback. Also, it will be possible to choose, during editing, certain passages from tape No. 1 and others from tape No. 2 etc.
