I am trying to write a buffer coming from a wav audio file to file.
By using an HTTP endpoint and then saving it from there, I get the file fully working.
By saving it using the File Node in binary encoding, it gets messed up and it is different from the buffer that originated it.
Here is a test flow (thanks to @BartButenaers) :
