Features

• Data-Over-Sound Transmission - Sends small amounts of digital data between devices using audio speakers and microphones without a network connection.
• Audio And Sounds - Provides a library for processing and synthesizing the audio waveforms required for data-over-sound communication.
• Frequency-Shift Keying - Uses frequency-shift keying modulation to encode binary data into audible sound waves.
• Acoustic Data Decoding - Converts incoming audio waveforms back into binary data using frequency analysis and error correction.
• Acoustic Data Encoding - Transforms binary data into audio waveforms for transmission between devices via speakers and microphones.
• Acoustic Data Transfers - Implements a protocol for encoding and transmitting digital data using audible sound frequencies between devices.
• Audio Data Modems - Acts as a software modem transforming digital information into sound and back into data via frequency analysis.
• Multi-Tone Demodulation - Extracts binary data streams by simultaneously monitoring multiple frequency bands during the decoding process.
• Raw Audio Streamers - Provides low-level interfaces for writing raw PCM samples directly to audio hardware for transmission.
• Waveform Generation Engines - Provides a cross-platform tool for creating raw audio samples and WAV files for short-range data transmission.
• Raw Audio Sample Streaming - Generates raw PCM audio samples to be pushed to audio backends for data transmission.
• Acoustic Air-Gap Transfers - Moves information between isolated systems by converting data into sound waves and decoding them on the receiving end.
• Fourier Transforms - Implements fast Fourier transforms to convert audio signals into frequency components for data decoding.
• Error Correction Codes - Employs Reed-Solomon error correction codes to detect and fix bit errors in transmitted audio data.
• Acoustic Pairing - Links two devices together by playing a unique sound code from one and listening for it with the other.
