I have a buffer containing audio data representing a voice recording, and I need to determine its loudness in Node.js. I tried using the fluent-ffmpeg library, as it seemed to offer functionality for audio analysis. However, my attempts to use it to analyze the loudness of the audio buffers were unsuccessful.
Could someone please suggest a reliable approach or provide a code example to help me analyze the loudness of the audio buffers accurately in Node.js? Any guidance or assistance would be greatly appreciated.
