Abstract:
1. A method for digital signal manipulation, comprising: receiving an acoustic analog signal at a user system; converting the analog signal to a digital signal; canceling noise from the digital signal to form a processed digital signal; detecting user speech in the processed digital signal by evaluating change in amplitude sign of the processed digital signal; and if user speech is detected in the processed digital signal, packaging the user speech into speech packets to form a packaged voice signal; selecting a transmission format compatible with the packaged voice signal; and transmitting the packaged voice signal to a server; receiving non acoustic data at the user system; and if user speech is not detected in the processed digital signal, packaging the non acoustic data into data packets to form a packaged data signal; selecting a transmission format compatible with the packaged data signal; and transmitting the packaged data signal to a server.
