Extracting raw audio streams from Zoom meetings can be beneficial for various applications such as real-time sentiment analysis, transcription, and capturing action items. To achieve this, developers need to use the Symbl.ai SDK, which provides a JavaScript library to connect with Zoom's PSTN mode. The process involves initializing the SDK, setting up the DTMF sequence, and establishing a connection with the meeting. Once connected, the developer can subscribe to the live events on the connection to receive real-time transcripts, which can be used for various purposes such as sentiment analysis or action item capture. By using raw audio streams, developers can work with unaltered data, providing better opportunities for reading and analyzing the audio in its original form.
