TrillBit's data over sound technology is facilitated through the following protocols:

  1. VoIP protocol: Transmission of data over sound via phone line.

  2. Audible protocol: Most applicable to use-cases where audibility of sound transmitted is required or desirable.

  3. Frequency of 16 KHz: Most applicable for Embedded devices supporting this sampling rate.

  4. Ultrasonic protocol: This supports data transmission that is inaudible with frequencies of 17-20KHz.

Additional protocols for user specific use-case, are available on request.
