Sonify

Converts tabular data (CSV, JSON) into audio waveforms by mapping numerical values to acoustic parameters (pitch, volume, timbre, duration). The system uses a parameter-mapping engine that establishes relationships between data dimensions and sound characteristics, allowing users to define which columns control which audio properties. This enables intuitive audio representation where data trends become audible patterns rather than visual charts.

Provides a live-preview interface where users adjust sonification parameters (pitch range, tempo, instrument selection, volume envelope) and immediately hear the resulting audio without re-rendering. The system uses client-side Web Audio API synthesis with parameter binding, allowing sliders and controls to directly modulate audio generation in real-time. This tight feedback loop enables rapid experimentation and parameter discovery.

Enables users to control the temporal playback of sonified data through adjustable playback speed, allowing fast-forward through large datasets or slow-motion analysis of specific regions. The system maps data rows to time intervals and allows users to compress or expand the temporal axis, effectively changing how quickly data unfolds as sound. This supports both exploratory listening (fast) and detailed analysis (slow).

Provides pre-configured sonification templates optimized for specific data types (time-series, distributions, categorical comparisons, correlation matrices). Each template includes sensible defaults for parameter mapping, pitch ranges, instruments, and playback speeds based on domain expertise and accessibility research. Users can select a template matching their data type and immediately generate sonified audio with minimal configuration.

Generates audio output designed for accessibility compliance, including support for screen reader integration, adjustable audio levels to prevent hearing damage, and audio descriptions accompanying sonified data. The system may include features like mono/stereo options, frequency range optimization for hearing aids, and loudness normalization to LUFS standards. This ensures sonified data is usable by users with various hearing abilities and assistive technology.

Automatically normalizes input data to appropriate ranges for sonification (e.g., scaling values to 0-1 or to a specific pitch range) and handles outliers that could produce unintuitive audio. The system may use techniques like min-max scaling, z-score normalization, or percentile-based clipping to ensure data maps to meaningful audio ranges. This preprocessing step is critical because raw data values often don't map intuitively to audio parameters.

Allows users to export sonified audio in multiple formats (WAV, MP3, potentially MIDI) and share results via links or embedded players. The system handles format conversion, compression, and metadata embedding (e.g., title, description, sonification parameters). This enables integration with external workflows and sharing with collaborators or audiences who cannot access the Sonify interface directly.

Enables multiple users to work on the same sonification project simultaneously, with shared parameter configurations, version history, and commenting. The system likely uses real-time synchronization (WebSocket or similar) to propagate parameter changes across connected clients and maintains a project state that persists across sessions. This supports team-based accessibility work and collaborative data exploration.

Provides a library of instruments (synthesized or sampled) and musical scales (major, minor, pentatonic, microtonal, non-Western scales) that users can select to influence the sonification's tonal character. The system may include culturally-specific scales and instruments to accommodate different user preferences and accessibility needs. This allows the same data to be sonified in different musical contexts, potentially improving intuitive understanding for users from different cultural backgrounds.
