Why is the audio encoder output timestamp different from the input timestamp #803

`const init = { format: "s16", sampleRate: 48000, numberOfFrames: PCMData.length / 2, numberOfChannels: 1, timestamp: inputTimeStamp, data: PCMData, }; const frame = new AudioData(init); this.AudioEncoderObj.encode(frame);

output(frame, meta){ let outputTimeStamp = frame.timestamp; }`

why the outputTimeStamp is different from the inputTimeStamp?
