AudioImporterSampleSettings

Эта структура содержит набор настроек, используемых для определения того, каким образом должен быть импортирован AudioClip.

Unity использует эту структуру с AudioImporter для определения того, как импортировать и загружать AudioClip в Scene. Это полезно, если вы хотите изменить настройки импорта группы аудиоклипов на те же самые настройки программно. Вы также можете изменить их в Inspector аудиоклипа.

// This script creates a custom menu item. If you click this item, it reimports the audio files
// (from a certain directory) with new import settings. The settings contain overrides for 
// multiple platforms (Default, Standalone, and Android).
