-if there is no result in 7 days, I will try to send bug report or email.
--------

-Known problems:
-	- iOS or macOS Safari: Call the 'MediaStream' object obtained by 'MediaDevices.getUserMedia({audio:true})', 'MediaStream' first use is no problem, but if 'MediaStream' second use will be a problem. If you call 'MediaDevices.getUserMedia({audio:true})' again to get 'MediaStream', there will be no problem.
-	- iOS: if any audio has been played before calling 'MediaDevices.getUserMedia({audio:true})', recording will not be possible at all. If the getUserMedia is called first and then the audio is played, there is no problem.
-	- chrome and firefox don't have any of the above problems.
-
-Test flow:
-	1. use 【iOS】 or 【macOS】 Safari:
-		step:
-			1. reload page
-			2. click 'Open Stream', grant permission
-			
-			//first recording
-			3. click 'rec start'
-			4. recording for a period of time, click 'rec stop'
-			
-			//keep stream, second recording
-			5. click 'rec start'
-			6. recording for a period of time, click 'rec stop'
-			
-			//new stream, third recording
-			7. click 'Close Stream'
-			8. click 'Open Stream', grant permission
-			9. click 'rec start'
-			10. recording for a period of time, click 'rec stop'
-		problem:
-			- first recording and third recording was right. but, second recording was wrong, the data transmitted by the browser seems to be fake.
-	
-	2. use 【iOS】 Safari:
-		step:
-			1. reload page
-			2. click 'Play mp3'
-			3. click 'Open Stream', grant permission
-			4. click 'rec start'
-			5. recording for a period of time, click 'rec stop'
-		problem:
-			- time varies abnormally slowly(onaudioprocess callback).
-			- almost no animation on the recording volume. 
-			- playing record discovery: recorded data is wrong.
-		
-	3. use 【chrome】 or 【firefox】
-		Retry '1.' and '2.' above. no problem at all.
