Describe the bug A clear and concise description of what the bug is.

Thank you a lot. It's a cool sound plugin. After i used FlutterSoundRecorder to record a pcm16 codec sound , then FlutterSoundHelper failed to get that sound file duration ,with a error above.

Please look to this :

Note the following limitations in the current Flutter Sound version :

• The stream is PCM-Integer Linear 16 with just one channel. Actually, Flutter Sound does not manipulate Raw PCM with floating point PCM data nor with more than one audio channel.
• FlutterSoundHelper duration() does not work with Raw PCM file
• startPlayer() does not return the record duration. withUI parameter in openAudioSession() is actually incompatible with Raw PCM files.

This will be certainly alleviated in future.

Thanks a lot. Could you tell me how to prepare network sound? It costs many seconds to waiting for sound after calling startPlayer(remoteUrl) .

ok i will try startPlayer(fromDataBuffer)

Another Flutter Sound user had the same problem than you : the delay when starting a playback from a remote site was too long for him/her. This is another point that we will work on soon.

Yes, if you download your remote song, there will be no delay when startPlayerFromBuffer()
