1. A computer implemented system that preprocesses audio portions of communication to enrich multiparty communication environments, comprising: a connection component that hosts or joins a multiparty communication session in which at least one party is a remote party; an interface component that provides a public channel to present or transmit a public communication received by substantially all connected parties, and that further provides a private channel, simultaneously with the public channel, to present or transmit a private communication received by a selected subset of all connected parties; and an audio transformation component that applies an audio transform to an audio portion of a communication over the public channel or the private channel in order to preprocess the audio portion prior to presentation or transmission of the communication by the interface component, the audio transform being based at least in part on a target audience of the communication.
