On page 223: https://books.google.com/books?id=w0... 0audio&f=true
The word 'waveform' should be replaced with 'envelope'. |

Trevor, geoff:
Well, it's still a fine line. In the book, the image shows individual up&down spikes, of a piece of sound a couple minutes long. To me that's a waveform. If I zoom out so that the spikes & lines all blend together, it "could be" an envelope. Not the one in the book, but: http://www.zytrax.com/tech/audio/note-adsr.gif In that link, the dotted lines along the peaks to me are the envelope. The up & down squiggly line is the waveform. That image clears things up nicely. |

Trevor, et al:
Well, thanks for nothing guys. I posted this as a test, and you all failed with flying colors. If that textbook calls it a waveform, and that book helped graduate multitudes of audio professionals, then I ain't disputing it. As for envelopes, here's the best example I've yet found: http://acad.carleton.edu/courses/mus...inEnvelope.png NO spikes, no frizzies, no wigglies - just an outline. And if this ain't a WAVEFORM: http://www.sonycreativesoftware.com/...2013-05-01.jpg then I'll eat it! |

But no, he was just playing his usual role in the "Magic Shortbus" sitcom. Magic Shortbus main title theme He was "testing" the people who have been doing audio production for decades, and he says they "failed". laugh track When he was younger, he always did poorly in school because all his teachers "failed" his "tests". He shows the pictures (although his original links seems to have "failed the test"), and then blubbers about them without a clue. Then he points at the pictures, and says, "you failed". laugh track And he moans about forums where nobody responds to a thread where he's soiled himself like this. FCKWAFA. NO spikes, no frizzies, no wigglies - just an outline. I'll eat it! Bone apple teat. |

" You can't make any presumptions as to what I know and don't know about audio Trevor. Not that anyone in this good-ol-boys club has been of any help to me... Your own descriptions(not just Trevor's) of at what point a visual representation of sound becomes an envelope or a waveform are at LEAST as vague as in that book I linked to. The point at which a waveform begins to resemble an envelope has more to do with the size of your working monitor and also with how zoomed in or out the image is. There is no rigid definition, and that's why you haven't been able to provide a straight answer. |
