Play audio from buffer

[xoapit]

Hi all,

I am trying to join buffer and playback it. Does anyone have a idea for this case.

Thanks in advance.

@xoapit did you find a solution for this?

[xoapit]

Actually, I cannot do it. I have some ideas to record VOIP in android device. But most of them are not supported to record VOIP so I tried to do this in the server.

Someone could find a solution for this? @xoapit @GiampaoloComida @brycepavey

@eduardotamaki my colleague created a fork where we use a circular buffer.
This was for a client project so it's not maintained beyond our requirements for that, but it might still be able to help you. Check it out here though https://github.com/dreamwalk-os/react-native-audio-record

@brycepavey that's awesome!
We'd love and welcome a PR to roll that functionality into the main library if you're able.

@brycepavey Awesome, I will have a look to it...

I already resolve this, basically, data return from on('data', (data) =>{} is base 64 encoded for pcm format. It's almost the same as wav but missing the wav header

I do it in a tricky way, I don't care much about the header and the config is not usually change so I get the normal output wav (from result file path) and extract the header bytes (first 44 bytes). Every time I want to stream audio file, I stream these header bytes first, others bytes from base64 chunks will be sent later. (buffer is bytes array)

If your guys have better ways to build wav header, please let me know

A good package we're using at the moment is ffmpeg this allows you to create and convert audio files from mp3, wav etc... might help as we're using it to stream and build files in the server.
