const transcoder = new AudioTranscoder(ffmpegPath);
const inputPath = '/path/to/input.mp3'; // Update this with your input audio file path
const outputPath = '/path/to/output.m4a'; // Update this with your output audio file path
await transcoder.transcode(inputPath, {
codec: 'aac', // optional
outExtension: 'm4a', // optional
bitrate: 128000, // optional
outDir: outputPath, // optional
logProgress: true, // optional
