Web Audio Software Coding

Prompt

Act as an expert audio software engineer and design a robust, high-performance, browser-based audio mastering workstation using modern web technologies. The core architecture must support a professional-grade, modular signal chain with advanced mastering capabilities—such as multi-band equalization, dynamic range compression, mid/side processing, limiting, and real-time spectral analysis. Ensure the application runs entirely client-side, prioritizing low-latency playback and highly efficient memory management for handling large audio buffers without relying on backend server processing. For the output pipeline, construct a bit-perfect rendering engine that guarantees absolute audio integrity from the final mastering stage to the downloaded file. You must implement client-side encoding to support lossless, high-fidelity exporting specifically in WAV, Apple Lossless Audio Codec (ALAC) M4A, and Free Lossless Audio Codec (FLAC) formats. The final solution should pair this uncompromising sonic quality with an intuitive graphical interface, allowing users to seamlessly import tracks, tweak their mastering chain, and export their final masters natively within the browser.
