Oboe Vs. Voice (assign 4)

September 14, 2009

Okay, so the oboe analysis was frankly, rather boring. It was beautifully constant throughout the sound sample, in pitch, loudness, and brightness. There was a decrease in each at the very end, which makes sense, since the sound is dying out. The oboe sound is very constant and pure, with clearly defined partials (can be seen from a spectrometer analysis), which is why it is used as a tuning instrument for the orchestra.

The voice was much more interesting. It varied throughout the entire duration of sound, in pitch, loudness, and brightness. Of course, most of this is not readily discernible just from listening to the human voice (…it’s actually very musical! even when the language being spoken is not tonal)(I did pick a particularly charismatic voice sample, though – a speech by John F Kennedy.); sonic visualizer’s breakdown of the sound reveals the great range of nuances in the voice.

    The pitch plot of the oboe is not clear at all, you should have narrowed the frequency range in the analysis so we would see the frequency around 440Hz.

    Also the pitch plot in the speech is not clear, buy narrowing the range maybe it could have been shown better.

    Good for the rest.
