Waveform Renderer is a lightweight and customizable TypeScript library for rendering audio waveforms on HTML canvas. Its primary function is to create visual representations of audio files.

Features:

• Highly customizable appearance.

• Performant canvas-based rendering. This indicates that the library uses the HTML canvas element for efficient drawing of the waveforms.

• Responsive and touch-friendly, making it suitable for various devices.

• Real-time progress updates, allowing users to see the current playback position.

• Interactive seeking, enabling users to navigate through the audio by interacting with the waveform.

• Written in TypeScript with full type support, which enhances code maintainability and provides better developer experience.

• Resolution independent with HiDPI/Retina support, ensuring crisp visuals on high-resolution screens.

• It offers various configuration options to control the waveform's appearance, such as color, background color, bar width, gap, and progress line styling.

• It provides support for events such as renderStart, renderComplete, seek, error, destroy, ready, resize, and progressChange, allowing developers to respond to different states and interactions.

• The library exports a main WaveformRenderer component and a utility function getPeaksFromAudioBuffer for calculating waveform data from raw audio.

• It includes methods to setOptions, setPeaks, setProgress, and destroy the waveform instance.

• Waveform Renderer is designed to be a focused alternative to larger audio libraries like wavesurfer.js, concentrating solely on waveform visualization and thus having a smaller bundle size and optimized performance for waveform rendering. It does not include features like playback, regions, or spectrograms.

• It supports modern browsers that support Canvas and ES6.
