var filename = "test.mp3";
var fileSource = new UniversalSourceBlock(await UniversalSourceSettings.CreateAsync(new Uri(filename)));

var adpcmEncoderBlock = new ADPCMEncoderBlock();

pipeline.Connect(fileSource.AudioOutput, adpcmEncoderBlock.Input);

var wavSinkBlock = new WAVSinkBlock(@"output.wav");
pipeline.Connect(adpcmEncoderBlock.Output, wavSinkBlock.Input);

await pipeline.StartAsync();
