Stereo-Mono Issues

Quote:

Oh and weedwacker if you think SD is west enough to have coyotes everywhere and their so easy, come on out and give it a whirl. We all are at risk of seein the bullst-t flag being thrown when you start sayin numbers.



Red Randi, I see people all over SD killing coyotes. I take it you're having a problem getting a few. /ubbthreads/images/graemlins/laugh.gif Maybe you should try the new Scorpion. And be sure to place it WAY upwind as I'm sure they could smell your BS from a long way off. /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif /ubbthreads/images/graemlins/laugh.gif
 
Hey Randy, last time I spoke to Scott he said that mange had reduced the population densities in S.D. to 40% of previous years. Is that true in your district? If so how are you state trapper/predator control specialists earning your paychecks?

In 2002, the Jesamine County Gazett newspaper did a full page artical about the hundreds of coyotes Possumal has killed in Ky. He's been steadily putting them on the ground since then. Last weekend he called in 12. That's a typical weekend for him. You would have to look long and hard to find anybody in the East that kills anywhere near the numbers he does. 12 may not sound like a high number to people out West were there are coyotes everywhere, but here in the East that's quite a feat. I doubt that very many Western hunters could come over here and call in those kind of numbers.



Those #'s sound kinda inflated for KY.
 
Rich there are still going to be a certain % of those coyotes regardless of population trends that are going to kill lambs, ewes and calves. How many coyotes have you seen that get to killing lambs and they just stop killin?

Our #1 priority is to our producers first and foremost, but we also do antelope aerial surveys, doe/fawn deer surveys, grouse Lek surveys, fish surveys,pheasant roadside surveys, dove roadside surveys, prairie dog control,plague monotoring in coyotes and p-dogs. Fish spawning, duck counting, beaver control, coon control, posting of signs at WIA's and GPA's. Give talks to school groups and other org's.

As our coyote numbers rebound the time we have available for these other activity's is less, as again our producers are our top priority. The population trend isn't the same state wide and what the producer perceives as a problem varies as well.

If we want to debate numbers and what ADC is about then we can start a new thread. Good day.

Weedwacker, once again you side step the post, if ya have something to prove the original post to be valid post it. I have not seen it, prove me wrong.

If you are questioning my ability or experience, look around, you will find a post or two to verify it.

Once again a stereo or mono factual statement with proven results would be nice. Not a 20 years ago, well maybe now it's 5 years ago, and hundreds to 4-6 pics. Then 12 a weekend to what's next. Your losing ground everytime you post. There are alot of coyote callers here that are smelling a rat!

Rich as you know the SD is not a federally run program but a state program and thus is run accordingly. We are active in all aspects of the GFP in certain degrees. Livestock loss is our #1 concern but as ADC stated we wear many hats. Our plates are always full! Especially here in the capitol!

The one thing about numbers we are basing the 40% off peak years and as I have witnessed this year denning we are seeing an increase in litter sizes, 8-10's were common, where 4-5 is the norm. Mange is clearing up in some areas and off they will go. Facts you are well aware of my friend.

WW maybe if you go back and edit the original, like you have edited the others, to say something like Al takes more coyotes here in KY than most, and has some unusual methods that work for him. If ya want we can start another thread and post the proof and stop hijackin this one.

My apologies to the PM staff.
 
I find this intentional changing of a users name when addressing them rather childish and surely shows signs of ignorance, bordering on stupidity.........
 
Not quite yet, since the back and forth brought up several salient points that deserve a response.

Without going too deeply into Al's bone fides, suffice it to say he shoots way more than his fair share of monster eastern coyotes, but no where near the numbers that were mentioned above. Al has shot 20-30 coyotes each of the last several seasons himself, and called another 20 for guests he has taken hunting in the East. He's a Kentucky rifleman, who uses an FX5 placed on the edge of cover well in front of him, utilizing remote at longer ranges, in conjunction with scents and decoys.

Al is also one of the few posters with any experience with other callers like the WT and Minaska. And he's also one of the few posters who edits his own sounds to any great degree. Al puts together long sound sequences that change volume and sometimes fade out entirely without requiring a single touch of the remote. He, like me, cannot read the display on his TX200 remote, and has been vocal about this shortcoming, and relies to a great extent on his expertise at sound editing rather than remote control to produce the desired calling effects. Anyone interested in Al's sequences can find a few examples at Varmint Al's website (no relation to Al P.).

I've been toying with stereo versions of calling sounds for a couple of years, and actually got started many years ago using converted car stereos and a boombox with limited remote capability using an RC car/airplane control. None of these original callers were satisfactory due to the difficulty I encountered editing reel-to-reel, 8-track, and eventually casette tapes with a razor and scotch tape. Long ago, these crude callers were relegated to the rubbish heap and I drifted back to mono for calling, the JS 512 on the ground and a PA on the truck. Editing stereo sounds to any great degree has only been made possible by the development of micro computers and digital sound storage. Even as recently as 5 years ago, digital media was so expensive that calling sequences were still better stored as short mono sounds as exemplified by the early WT's use of 32KHz mono files. New sound editing software is amazing. And finally, just in the last 24 months, with a Gig of storage now approaching $10., it's possible to play with stereo cards on a remote machine again. There are very few guys out there with any experience hunting with stereo files. It's a brand new feature.

Up to this point even Al hasn't had any experience with stereo. His Fx5 is mono. And FXP files are not editable by the user. If Al edits any stereo for his new Scorpion to throw barks or whines as I described above he will have to rely on his WT or JS sounds as a source, or on one of the Dillons to do his editing for him.

The Minaska Big Country is a stereo caller I've used for 2 years now. When I originally posted my question about my FX caller's poor performance handle-to-handle next to the BCB at the club demos and the camp out, I really thought mine was flawed. My own stereo files sound awful on my FX5 and dynamite on the BCB. Now, after this last trip, there are also 200+ hardcore predator callers out there who will for the most part agree with my results. Are stereo sounds useful in a hunting context? That remains to be explored. I think they really help display the differences between the two-speaker callers to human ears - but as for the coyotes, they're not talking. If stereo sounds are not an important feature, why is FoxPro introducing two new brand new callers featuring totally redesigned stereo circuits? You know for sure they don't like my comparisons or criticisms or playing catch up with Minaska. It cost them plenty to introduce these two new callers. I'll also go out on a limb and predict they'll be mixing some new totally discrete stereo sounds like those I've described for users of the new Scorpion and Prarie Blaster soon, just to show off the stereo capability of their new callers.

Will that make the FX3 and FX5 obsolete?

That says alot right there. It seems that calls are being developed to satisfy the "wants" of the hunter. Forty years of using hand-calls and a crappy ol' cassette player has shown me that the animals could care less.

You are probably right. Hunters wanted "scent-lock" suits, breath killing gum, odorless gun cleaning solvent, camo that would make them invisible, etc. All of those things weren't necessary before and they aren't necessary today. Predators and other animals have been called and killed for years without any of that. It's the hunters thinking they need it that has created a market for it. I hold no ill will towards the companies that market these things. They are providing what "people" want, not necessarily what is "needed" to call and kill animals.

I couldn't begin to count the number of animals called with this cassette player. The speaker is a cheap Fanon, public address speaker, 7.5 watts, 8 ohms. It worked 40 years ago and would still work today. After having Foxpro remote callers I don't want to go back to it, but I could call animals with it just like before.
 
Darn Nahuatl, you are going to give away some of my best kept secrets if you don't watch out (lol). It appears that some of the fellows have been jerking each other's chain a bit in earlier posts, and I agree with Weasel that we can cease and desist on that. I agree with you that other points have been brought up. As for numbers of coyotes taken, I have never felt that I needed to brag about numbers or size. At the time Ricky Elkins wrote an article about me in the Jessamine County Journal, April 2002, I had just completed my 11th year of coyote hunting, and had killed just under 400 coyotes, an average of about 35 per season. Mr. Elkins saw ample photos and logs to back up the numbers. I hunted mostly solo until I started training two grandsons year before last, and I take a lot of pride in their accomplishments so far. As far as my experience with stereo callers, I had a lot of experience in that area when I was helping Chris Talley of Idaho when he was developing the Critter Magnet modular system, and we learned lots of interesting things about stereo sounds as it applies to coyotes. As for the current field testing, several of the Foxpro Field Staff members have been using the Scorpion. I know Glenn Guess has had some success and haven't read much about the other testers. I have had the unit out a total of 5 different days, using only the onboard built in speaker. I have made a total of 12 stands, calling in 15 coyotes, 8 of which are now dead. I am getting ready to do some testing on the stereo aspects if I ever get over a bad case of flu. I do appreciate the remarks about expertise at sound editing, but I was using that feature before the FX-5 was even out. I use sequences to cut down on movement and to keep my concentration on the terrain, and to present as realistic a scenario as I possibly can. Your methods obviously work well for you, and I have posted before that I thought Minaska made a wise choice in naming you to their field staff. Nothing has happened to make me change my mind.
 
Seems to me like there'd be a rather narrowly-restricted usefulness to stereo sound in actual predator calling situations.

Absent highly directional speakers bouncing the L/R channels off a distant canyon wall, unless there's a substantial amount of speaker offset (and sheesh, does this mean we're back to using very long speaker cables once again-- negating one of the few advantages to using radio remotes?), parallax is going to be almost nil beyond few dozen yards.

Meaning, at most normal shooting distances, when considered from the critter's perspective, both components of the sound will be coming from very nearly the same direction. Now, I can see where once the animal gets close in, say to within a couple or three dozen yards, it might be possible to get it to hang around a little longer to look left and right, momentarily confused. Which all might have some limited utility for us photographer types, (maybe even bowhunters) but probably isn't worth all this splitting hares, to most fellers.

Anyway, what's to prevent someone from doing this better, and more wirelessly, using two wireless callers-- say for example, two original-style Foxpro units, controlled by one switched transmitter?

Gary,

I was using a "stereo" boom boxes many years ago. I would bet I was not the only one using this type of caller in the 80’s and early 90’s.

Mixing sounds in the analog domain is a bit more challenging but do able all the same.

Your right the digital world has made it easier. I started using digital audio software in the very early 90's.

I think you should buy Jay Nistetter's and Al Lux's book "PREDATOR CALLS the First Fifty Years" and turn to page 273 you will find an old "stereo" commercial electronic game call add... In part the add reads...

"The dual speakers and stereo sound provide more realistic calling noises..."

This may not be the first stereo one either as I'm not claiming to be a historian but it is from the 80's.

You may need your reading glasses to read this old add as it has pretty small print. It is quite a bit smaller then the print on the TX-200.

Are we all possibly playing catch up from this manufacture that had this "brand new" feature you described long ago?

It is a big world... I can tell you we are not the only 2 manufactures or individuals past or present that have had or have interesting ideas for predator hunting. I remember being told long ago by a few old timers of them attaching a feather or two to the platter of a record player... a caller with built in decoy from long ago!!!

There are a lot of cleaver and bright individuals in this world that can come to the same conclusions as to what features are needed and what methods of hunting that works. A lot of this is evolutionary not revolutionary.

Look at the home theater and home audio markets to find some cool features that may come to callers in the future... Moore’s Law is great.

Should we add some Baxandall or other tone filters? My boom box had them. I'm sure your car stereo callers did as well. Would this be a new feature? Maybe with presets...

I have a few of the Minaskas callers in our possession and I have yet to see any of their sounds mixed in true stereo format, meaning different data on left and right channels. Can you tell me what I'm missing? If this was such an important feature why are the sounds that are mixed not in true stereo format? The same data is on both channels. I am not knocking them for this, as we don't have any true stereo sounds either... yet.

Your right we may mix sounds in stereo if that is what our customers want. Are we wrong in doing this for our customers who don't want to mix their own sounds?

You seem to be making a bigger deal out of this mono/stereo then we or they are... If the customer wants to use this "new feature" great, if he chooses not to he can set it up in mono and that is fine as well.

I also wonder why you never made big deal about stereo until we came out with a stereo unit. If it was so important why did you not share this "new" found method with everyone? Why does this appear to rub you the wrong way that we came out with a possible useful feature for our customers?

I would have thought you would welcome the fact that we made a stereo caller with more control to add to the hunters "tool box". We believe that this was the time to add the stereo feature because it opens the door to different calling scenarios now that you can control this feature from the remote in our units. How much this will actually help is most definitely an unknown and remains to be seen. If this feature helps the hunter to feel more confident in his calling ability then why would we not want to help them? Confidence is as much a part of hunting as anything. Should we cry foul if any competition introduces this speaker on/off feature as well to help their customer base?

I do think stereo sounds have a LIMITED use. Can you tell me how much stereo separation remains at 50-200 yards? ...all of this with only a few inches between the speakers in the BCB and the PB. I believe stereo to be a more useful feature when you can turn the speakers on and off independently from a remote, imagine different species on each track. I believe this is more important then the perceived motion you may create by cross fading. I'm not discounting that possibility or scenario either. With some new modern DSP's you can do that without editing!

I also wonder how a controlled mono/stereo test could be implemented. I can see lots of variables coming into play. If one would see an increase in their predator harvest could they solely attribute it to these new audio set ups or could other variables be the reason? I am a believer in the empirical testing method but sometimes it can be easy to allow yourself to be fooled.

I certainly don't want to sell this stereo feature as some great magic elixir that will help you call more critters then ever before! How many furry backstops have been harvested with mono sounds?

Do you remember when we FOXPRO were accused of increasing the sounds on the FX5 only because the competition increased their capacity? We had to show the JUKEBOX mode on the FX3 to prove it was something we were looking at and working on. Does FOXPRO need to have a complete disclosure of all of the features and products we have talked about or the ones that are currently being worked on? Do you think we do not have our own ideas and thoughts? Is it wrong to allow a new feature to mature in engineering instead of running right out with it?

And the last question... If our FXP Foxpro files are not able to be edited or manipulated how in the world did the DSG Cottontail get in your Minaska game calls?

The consumers that are truly into editing sounds are already aware how this can be done as you are. Those that are just getting interested in mixing will soon learn how this can be done using their new found skills and software. I have said it before people are bright and resourceful. I think it is a safe bet to say most hunters remember the analog world.

One speaker blasting to the north, one speaker blasting to the south. Two distinct sounds, one close and one far? Isn't that how the a sound cone works? Siren coming toward you and one going away?
 
Dentra,

Do you use mouth calls? If you do here are a few things to try out. When you are blowing on a mouth call where do you perceive the sound is coming from? If someone is behind you where do they perceive the sound is coming from? What direction is the open end of the bell facing?

If a car blows the horn and you are facing the rear end of the car twenty feet behind it where do you perceive the sound is coming from? If you turn a speaker away from you where is the perceived sound source?

If you want to find out more about this do a search on polar responses, backscatter, infinite baffles, sound boards, etc.

Granted the higher frequencies are attenuated when off axis, but if a predator was never called before what bases of audio comparison does it have?

Have you ever had a coyote come in the back door of your set?

Best Regards,
Steve

Don't you think that distance is the hardest thing for a predator to figure out? I'm sure they can determine where a sound is coming from as far as the angle, degree or the azimuth is concerned. And they also can determine if the sound is coming from above, below or on the same plane as them. Do they determine the distance from past experience with choking rabbits. Why do coyotes throw their head up and back when howling?
 
Dentra,

I don't know how a coyote estimates distance. All I can relate to is how we humans who have somewhat poor hearing when compared to canines and other animals. We as humans can estimate distance… sometimes not very well. This is sometimes dependent on atmospheric and physical terrain and foliage, etc conditions. When humidity is up and cloud cover is heavy how do you hear things differently? I can hear trains that are far away under these circumstances. Is it fair to say animals have the cognitive ability to reason or do they just have a better grasp on where sounds are propagating from do to their highly evolved hearing? I would not want to credit the critters with the cognitive ability to reason. Isn’t that what separates us from animals?

I'm certainly no expert on coyote behavior or the physical make up of animals vocal chords and their respective physical science of their vocalizations. Why do coyotes tilt their head back? I cannot say as I am not the best one to answer that question.

If I would say anything it would merely be my interpretation and nothing more. Could it be to better align their tongue to manipulate the air chamber and vocal chords that would allow better control of the pitch of the howl? I certainly would not claim this to be true it is just a hypothesis. Your guess is as good as mine.

Regards,
Steve
