JAGUAR has a wide selection of different type of FILTERS and these can be tuned with several tools. However, JAGUAR LITE only offers one fixed filter (STOCK). JAGUAR's filtering is implemented in the time domain using 100-ms slices at a time (0.1 sec thus being the smallest operational "audio unit" in JAGUAR).
The following filters are available in JAGUAR PRO:
AM MODE is not actually a filter but a different demodulation mode; the filter itself uses JAZZ filter processing. It can be handy to have AM MODE as "one of the filters" when trying to find the optimal audio output in each case.
Each filter can be used in three modes: BASE / STEEP / STUDIO. These modes have different attenuation curves at the filter edges.
The bandwidth and offset of the STOCK filter cannot be set; STOCK is the fixed "reference filter".
The filters can be rotated with the "F" key (however, the first "F" press does not change the filter, it just opens the FILTER applet). The desired filter can be selected also by:
The filter characteristics can be changed by means of:
See the corresponding HELP for AUDIO, AUDIOBAR and BOTTOM WINDOW.
STOCK is the standard reference filter in JAGUAR. STOCK (as any JAGUAR filter) can be used in the BASE filter mode or in the STEEP / STUDIO filter modes. The bandwidth of the STOCK filter is 3.0 kHz and the filter offset is 0.3 kHz. The STEEP/STUDIO modes provide additional attenuation to the low and high ends of the filter. The effect can be seen in the AUDIO WINDOW and heard in the headphones. Sometimes you will get a clear improvement in the audio by using the STEEP mode.
CALLIOPE is a filter used for test purposes. The CALLIOPE filter can leak audio +/- 96 kHz away from a frequency of a nearby powerhouse. It is never a problem if you listen to the frequencies of your local continent but can be an issue when listening to trans-oceanic signals, and the frequency you are listening to is matching that 96-kHz difference from any nearby broadcaster.
JAZZ is probably the best JAGUAR filter in most cases.
