Precept, week 7:

• EIN[LS95] wraps audio around your C code. It runs on the MECA machines from /u/paul/m325/bin/ein.
  
  
• Audio signals: Getting hold of the numbers inside a formatted audio file (like .wav, .aiff, or .au) can be tricky because of the header formatting and weird storage conventions. To circumvent those problems, and also facilitate conversion to sound, we'll use EIN, a tool developed for COS/MUS 325. EIN is accessible on the MECA lab machines, and a paper describing its use in the article [LS95] mentioned above.
  
  
• Download some .wav files from the web (use a search engine to find them), and convert them to .aiff format using MediaConvert on the MECA machines. Or make your own files and do the same; there's a microphone somewhere on the machines in the MECA lab. Use EIN to look at the spectrogram of vowels in human speech, animal sounds, musical instruments, etc. To get started, tryhere for some sounds from Italy.
