I want to send a wav file to my project. I tried encoding the wav using base64_encode(file_get_contents()) which created a base64 string that I can pass successfully to Godot I tried to decode and create a new stream

var buffer = PoolByteArray() # Array that will hold the data.
    
var file = base64String
    		
buffer = Marshalls.base64_to_raw(file)
var stream = AudioStreamSample.new()
    
stream.format = AudioStreamSample.FORMAT_16_BITS
stream.data = buffer
stream.stereo = true

audioStreamPlayer.stream = stream

But sadly that doesn’t produce the audio that is being sent. Does anyone knows how to implement this?

did you set stream.mix_rate (for example 44100)?

you can also skip the first 44 bytes of the wav file as that contains the wav headers

stream.data = buffer.subarray(44,buffer.size()-44)

I haven’t tried with base64 encoded data but got it working with pure binary
