Attack

A dynamics descriptor. Transient response. Specifies whether the drumbeats and percussion, etc. are accurate and precise, i.e., if you can hear the actual strokes from the drumstick, the plucking of the strings, and such. It is also expressed as the ability to reproduce each audio source transient cleanly and separated from the rest of the sound image. Imprecise Attack is understood as having an unclear or muted impact. Scale applied in listening tests: Imprecise - Precise. [Reference: Report ITU-R BS.2399-0]
