I am using MediaRecorder API (https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder) to record/capture an audio from the browser. It works fine on chrome. But audio starts recording after few seconds delay on firefox (not every time). Struggling to solve this issue last 2 days. I ended up here for the help. I'm sure that someone might have faced this issue earlier. Can somebody help me on this? Same sample code has been used from the above link. I can provide my working code if needed.
