2.
Next, calculate the number of frequency points.
num points = (Stop Frequency - Start Frequency)/ Bin Spacing
For our example this would be:
num points = (2.65 GHz - 2 MHz) / 625
num points = 4,236,800
3.
Now, calculate the host computer memory required.
num data points = num points
×
bytes required per data point
For our example this would be:
bytes = 4,236,800
×
4
bytes = 16,947,200
For this example, almost 17 MB of RAM is required. The value you would assign to the
resource is in points.
Example:
*dataBufferSize: 4,300,000
The software fails when it cannot allocate the amount of memory you specify.
defaultAudioExtension
type: XmRString default: *.wav
Specifies the default extension for audio files. The possible audio extensions are:
*.u MuLaw (u-law)
*.al ALaw (A-law)
*.au Sun (NeXT)
*.wav Microsoft RIFF waveform
