Sound Delay is an auxiliary multi-channel signal delaying AAX, AudioUnit and VST plugin for professional sound and music production applications. You may specify delay time in both milliseconds and samples, with a high level of precision.

Sound Delay also features internal mid/side encoding and decoding, and allows you to delay mid and side channels independently.
