[edit] Dinosaur Fizzle Sounds

Besides the dinosaur_n, or dinosaur_noise .wav files, there have been 3 dinosaur_fizzle .wav files.

dinosaur_fizzle.wav was added in the first portal update.

dinosaur_fizzle2.wav and dinosaur_fizzle3.wav were added in the second update. No other dinosaur sound files were added in the second update.

[edit] Waveform analysis

This to note: The waveforms, when viewed with linear scale so as to see the amplitudes, does not have any DC offset or any strange appearance unlike dinosaur_noise.

The waveforms are generally similar, each clipping in the first few seconds, and then decaying afterwords.

[edit] Spectral analysis

Things to note: There is significant evidence of manipulation. Tones and temporal smearing are evident in all three, signs of varispeed pitch and speed adjustments are also visible. There is considerable reverb, or decay, and visible harmonic distortion.
