On a very basic 233 MHz Pentium-1 laptop with 32 Mb RAM, image processing took (nearly) forever-just four seconds The table below lists the processing times for the same WAV file on a variety of computers. The new sample-rate value will be stored for future use.Дecoding is highly processor-intensive and the time taken to produce your images depends crucially on the specification Select a weak but 'clean' signal, and set the sampling frequency mid-way between the upper and lower values at which lock A good way to determine the optimal value is to

Option which permits you to adjust the sample-rate by 1-Hz increments. vertically aligned) images, use the Sample frequency вЂ“ If this still fails to provide straight (i.e.

Outside this range, it is likely that there is something wrong with the wave file or, less likely, with your soundcard. Recommend a revised value if this is in the range 11,010 to 11,040Hz, accept it. May differ slightly from this figure (even a 5В Hz deviation will make the decoded images slant), and Satsignal will However, if you are using a slow, older computer, the sample-rate This to be accurate, processing starts immediately. The WAV files from weather satellite APT are always created with a nominal sample-rate of 11025 Hz. Start by loading this file into Satsignal byД¬licking on the main menu-bar, selecting, then navigating to the folder containing the WAV file itself.Дouble-click on the entry for this WAV file to initiate processing (for your first attempt, try to choose a good Such as Wxsat, WXtoImg, Recall or APTDecoder.

In order to use Satsignal you must already have available a NOAA satellite WAV file that has been created using software The channel A tab showing a visible light image The channel-4 infrared image side by side On the main Satsignal screen as shown below.ДЄ raw image consisting of the channel-2 visible image and Satsignal simultaneously decodes each WAV file into four separate images which can be viewed on the four tabs Result, performance is not hardware-related and anyone following the methods outlined below should obtain top quality Wx-receiver output level and the type of soundcard), Satsignal takes much of the hassle out of APT image processing byДЇully analysing each WAV file prior to decoding, and optimising basic decoding parameters before creating images. Unlike some other software packages, where results can depend critically on the hardware you use (specifically your Image Processing with SatSignal (unregistered version)
