Assignment 4

September 14, 2009

1) Harmonic

For this section, I used a note held on a violin, found on Freesound  here: http://www.freesound.org/samplesViewSingle.php?id=1269

The graphs show that for this note, the brightness and loudness hold constant, with the pitch fluctuating slightly as the violin settles on a final pitch, but hovering around the same level at 246 Hz.  Because the note is held for the whole period of time, the graphs stay pretty much level throughout the analysis.

Brightness:
Lucy Bailey
Loudness:
Lucy Bailey
Pitch:
Lucy Bailey

2) Speech
For this section, I used this sound from Freesound of a woman saying the word “group”: http://www.freesound.org/samplesViewSingle.php?id=72634

Compared to the violin sound, the Brightness, Loudness, and Pitch analyses are significantly different for the speech sound.  All three of the characteristics fluctuate heavily throughout.  The spot where the pitch leaps up for a brief period probably indicates the vowel section of the word being spoken.

Brightness:
Lucy Bailey
Loudness:
Lucy Bailey
Pitch:
Lucy Bailey

    These are good. Simple but very clear. If we would have taken a longer speech phrase we would see more the typical fluctuations of speech.
