cpp>>Сколько можно! Собери все цепочку аудио стрима и рули ей как хочешь.

A>Да, конечно, я так бы и сделал, Просто неприходилось раньше работать со звуком. А нужно от звука немного. А есть где-нибуть образцы "всей цепочки аудио стрима" с простой функциональностью? Я бы глянул. (это не важно, просто любопытство )

Примерно так (дальше писать лень):
