Answer 1

I got it working !!

All I had to do is adjust the number of channel.

I've set FFMPEG to output mono audio and it worked like a charm. Here is my new FFMOEG command:

var ffmpeg = child_process.spawn("ffmpeg",[
    "-re","-i",
    "A.mp3",
    "-ac","1","-f",
    "f32le",
    "pipe:1"                     // Output to STDOUT
    ]);

Answer 2

You are taking chunks of data, creating separate nodes from them, and starting them based on network timing. For audio to sound correct, the playback of buffers must be without break, and sample-accurate timing. You need to fundamentally change your method.

The way I do this is by creating a ScriptProcessorNode which manages its own buffer of PCM samples. On process, it reads the samples into to the output buffer. This guarantees smooth playback of audio.
