22" Paiste Symphonic Gong Spectrum

Paul,

Hello.

I've uploaded a 25 second sample of a 22" Paiste Symphonic Gong (44.1
kz), and my FFT values (in an Excel file), to the files section of
Egroups.

In the folder: "Ligon FFT".

Notes about my values:

FFT Size: 65536

The selected FFT size directly affects the resolution of the
resulting spectra. The number of spectral lines is always 1/2 of the
selected FFT size. Thus a 1024 point FFT produces 512 output
spectral lines.

The frequency resolution of each spectral line is equal to the
Sampling Rate divided by the FFT size. For instance, if the FFT size
is 1024 and the Sampling Rate is 8192, the resolution of each
spectral line will be:

8192 / 1024 = 8 Hz.

Linear Averaging

Linear - this method is a straight linear average of the spectra over
time. Each spectra block contributes equally to the average. This
type of averaging is also known as "stable averaging".

Averaging Block Size: 1

The averaging block size determines how many spectra blocks are
averaged together to compute a moving average. For instance, if the
averaging block size is set to 4, the spectrum currently displayed is
an moving average of the previous 4 traces.

Let me know how your results differ.

Thanks,

Jacky
