ndsamples is a lightweight JavaScript library that wraps audio sample data in an **ndarray**‑style structure. It enforces a standard shape (`[samples, channels]`), stores PCM data as a `Float32Array` normalized to ‑1…1, and attaches format metadata (e.g., sample rate), making it easy for audio‑processing tools (like read‑audio or node‑audio‑rms) to manipulate multi‑channel audio buffers. The package is aimed at Node.js developers building or analyzing audio streams who need a simple, consistent representation of raw sample frames.
