Abstract: A method and system of streaming media content is disclosed. The method and system includes a process step and structures for inputting the live feed into a first audio card having an output. Another process step and structures are provided for inputting the output of the first audio card into a FIFO buffer having an output. Another process step and structures are provided for inputting the output of the FIFO buffer into a virtual audio card having an output. Another process step and structures are provided for inserting additional content into a second audio card by replacing content to be substituted where the additional content and the content to be replaced do not have to be of the same duration. Another process step and structures are provided for mixing the output from the first audio card and the additional content by the second audio card to provide a mixed output. Another process step and structures are provided for inputting the mixed output of the second audio card into an encoder having an output.
