AUDIOBAR contains a set of buttons used for music and language recognition and quick finetuning of audio characteristics. If you need more tools and also want to see the exact effect of your changes in the audio frequency spectrum, you must open the BOTTOM WINDOW > AUDIO.
Audio finetuning: when clicked, the buttons normally toggle/rotate the allowed values. In addition to changing values by mouse-clicking, you can also move the mouse over any button and scroll with the mouse wheel, or use the left/right arrow keys.
AUDIOBAR is always visible when JAGUAR is active, containing the following buttons:
(( SONG ID BY SHAZAM: "LISTENING" ... ))
When clicked, the system tries to identify the music played, music audio data is collected and sent to the Shazam server. If the identification is successful, Jaguar triggers the Shazam web page for the music in reference. If the music can't be identified within 15 seconds, "NO MATCH" message is given. You can also cancel the process left- or right-clicking the button before 15 seconds has passed. More information can be found in the SHAZAM help.
(( TRANSLATE BY WHISPER AND GOOGLE: "LISTENING", "ANALYZING" ))
The TRANSLATE function can be used for speech signal processing to identify the language and to transcript and translate it to English - all you need to do is to click the TRANSLATE button. You can also cancel the process left- or right-clicking the button before the analysis phase. More details in the TRANSLATE help.
(( CR OFF | CR xx ))
CLICK REMOVER - Toggle the Click Remover ON and OFF, or change the active ON level by scrolling between Low (CR LOW), Average (CR AVG), and High (CR HIGH). More about this in the CR and APPLETS > WAVE help.
(( AGC ON | AGC OFF | AGC OFF+ ))
AGC (Automatic Gain Control): Rotate the AGC modes by left-clicking the mouse: AGC ON > AGC OFF > AGC OFF+. Scrolling will change the gain to the desired value and will set the mode to OFF (i.e. to the manual gain control). More info in the AGC help.
(( LSB | USB ))
SSB (Single-Side Band): Toggle the Lower Sideband (LSB) and Upper Sideband (USB). Not availabe if the AM MODE filter is selected.
(( AUDIO | HISTORY | BANDVIEW ))
The BOTTOM WINDOW is opened / closed with the selected topic. See BOTTOM WINDOW for more details.
(( STOCK | JAZZ | CALLIOPE | AM MODE ))
FILTER
Select the filter to be used: STOCK > JAZZ > CALLIOPE > AM MODE. The full range of filters is available only in JAGUAR PRO; in JAGUAR LITE, the only available filter is STOCK. More info in the FILTERS help.
FILTER CURVE
(( BASE | STEEP | STUDIO ))
STEEP and STUDIO are the "power filter" modes. The BASE mode allows some audio frequencies to leak in from outside the offset/bandwidth range; the audio output is soft and sounds like an old tube radio. The STUDIO mode creates a "brickwall", eliminating low and high audio frequencies as can be seen in the AUDIO WINDOW; the audio output is harder and sounds more like a "scientific" SDR audio. Often you will get a better output from weak signals using the STEEP/STUDIO filter modes but some use also the BASE mode often.
The audio response of these three filter curves can be visualized in the BOTTOM WINDOW > AUDIO (JAGUAR PRO only):
BASE is the basic audio filter curve:
STEEP cleans up more audio frequencies than the BASE mode. The effect of STEEP can be clearly heard in the headphones: audio with STEEP is crispier than in the BASE mode; however, we have lost some audio frequencies beyond the selected audio spectrum limits, but there is also a considerable suppression in the amplitude of the lowest (non-speech) audio frequencies. The filter curve is also much "steeper" at the filter edge than in the BASE mode.
STUDIO provides a more thorough clean-up of audio frequencies than the STEEP mode, and much more than the BASE mode. The effects of STUDIO can also be clearly heard in the headphones: the audio with STUDIO is the crispiest; however, we have lost more audio frequencies beyond the selected audio spectrum limits. In STUDIO, a lot of attention has been paid for eliminating the lowest frequencies. Even though most of these are located in the sub-audible frequency area, they may have some negative impact on the audio result / waveform. By default, in STUDIO we want to cut off everything as much as possible below the 80-Hz limit (= the lowest main frequency of the human speech). The filter curves are much steeper at the edges than in the other modes.
BANDWIDTH
(( BW x.x ))
Select the filter bandwidth in the range of 1.0 to 8.0 kHz in the steps of 0.1 kHz. Available only in JAGUAR PRO; in JAGUAR LITE, the only available filter bandwidth is 3.0 kHz. The available bandwidth range of the CW filter is 0.1 - 0.5 kHz (with a larger OFFSET range).
OFFSET
(( OFF x.x ))
Select the filter offset from DC (defaulted to 0.3 kHz). Available only in JAGUAR PRO; in JAGUAR LITE, the only available filter offset is 0.3 kHz.
DEFAULT (JAGUAR PRO)
(( DEFAULT ))
The DEFAULT button can be used to restore your "favorite audio settings" (as defined in SETTINGS > AUDIO > DEFAULT_FILTER | DEFAULT_MODE | DEFAULT_BW | DEFAULT_OFF) for the currently played frequency.
