Abstract: Methods and systems are provided for reusing audio streams in an audio mixing environment such that processing resources (e.g., CPU cycles) are not wasted on encoding the same audio streams multiple times (e.g., more than once). Instead, processing resources are conserved without comprising audio quality. The methods described herein are particularly useful when a participant transitions from using a shared encoder to using the participant's own encoder, and when the participant transitions from using the participant's own encoder to using a shared encoder.

Abstract translation: 提供了用于在音频混合环境中重用音频流的方法和系统，使得在对相同音频流多次编码（例如，不止一次）时，处理资源（例如，CPU周期）不被浪费。 相反，处理资源是保守的，而不包括音频质量。 当参与者从使用共享编码器转换到使用参与者自己的编码器以及当参与者从使用参与者自己的编码器转换到使用共享编码器时，这里描述的方法特别有用。
