“连续音的”可以翻译为 “continuous-sound(此处作为形容词性表达,不过更常见的是用短语形式来准确传达含义)”,更准确自然的表达方式是使用短语 “of continuous sound” 或者描述为 “featuring/involving continuous sounds” 。
例如:
The characteristic of this musical piece is of continuous sound.(这首曲子的特点是具有连续音。)
This instrument can produce sounds featuring continuous sounds.(这种乐器能发出连续音。)
