I need to burn an audio file received from a computer sound card. But in the new version of the gnu radio, I found that the "Wav File Sink" and "Wav File Source" blocks were gone. Tell me, how can I write to the WAV file now?
I am using the graph as in the picture, but the recorded file cannot be opened by the audio player: I get the error "The file cannot be played. The file format may not be supported, the file extension is incorrect, or the file is damaged". In this case, in the "file sink" block, I manually wrote the file extension ".wav"
