From a seed file (code.wav), decode the audio file (Bell 202 format at 200 bits/sec) into a binary stream and then convert the binary stream into a decimal vector (uint8) that should be hashed using SHA - 224, 256, 384, or 514 based on the function input. Output the hexadecimal hash (in lower case).

200 bits/sec - do you mean 1200?

No, 200 bits/second is correct for converting the .wav file into bits. The sampling rate is 1e5 and is part of the audio file.
