cricodecs v1.0.2

CriCodecs

CriWare codecs for Node.js. Uses Rust WASM modules for fast audio decoding.

Supports

• Node: v18.0.0+
• Extracting:
  • ACB
  • AWB/AFS2
• Decoding:
  • HCA
• Building/Encoding: Not supported yet.

Example

import { ACB, AFS2 } from "cricodecs";
import { writeFile } from "fs/promises";
const key = 1234n; // bigint

// Decode ACB
const acb = await ACB.fromFile("audio.acb");
await acb.decodeToWavFiles(key, "path/to/acb_out", (current, total) => { // Optional progress monitor
    console.log(`Progress: ${current}/${total}`);
});
// Dump HCAs
await acb.walk(async (hca, awbKey, isMemory, index) => {
    const path = `path/to/acb_out/${index}.hca`;
    await writeFile(path, hca.buffer);
});

// Decode AWB
const awb = await AFS2.fromFile("audio.awb");
await awb.decodeToWavFiles(key, "path/to/awb_out", (current, total) => {
    console.log(`Progress: ${current}/${total}`);
});
// Dump HCAs
for (let i = 0; i < awb.files.length; ++i) {
    const path = `path/to/awb_out/${i}.hca`;
    await writeFile(path, awb.files[i].buffer);
};
