The corrections
Posted: Sat Jul 14, 2018 4:36 pm
Howdy , for those who want to know , I've finished the new chart . This was bugging the living hell outa me because I put so much work into it and to fail over some kilobytes was unexceptable , it had to be corrected .
Here's how it happened .
I went back into the forest just on dark and set up a table with all 4 audio recorders .
I walked about 10 steps at every 2 metres all the way up to 30 metres away from the audio recorders .
Each footstep was measured from all 4 audio recorders which meant 8 measurements and then an average was taken . Each average of each footstep was then added together to arrive at a final average . This was done 15 times for each 2 metre increment .
The new chart has more than 1 BLUE column to indicate the unknown subject at various distances and not an average like before , this is a much more accurate representation of the subject thanks to Slats idea of distance . Also , each column may represent more than one footstep at a particular distance indicating the subject moving towards and away from the audio recorder .
The problem with this chart is that I still can't tell how big anything is . For example , a large subject may be tip toeing around the audio recorder giving me a false reading , or on the other hand a small subject may be walking heavily also giving me a false indication of distance . This will also be the case with stomping subjects .
Another problem is fallen logs , stumps , trees , boulders and heavy foliage partially block the sound from footsteps reaching the audio recorder which results in the subject appearing to leap from 10 to 30 metres in one single step and then back to to 9 metres distance .
The good thing is that the subjects can't hide their impacts and although the measured distance of the subject may not be the precise distance , the impact measurements speak for themselves .
Having measured the subject from video 47 and 4 seperate subjects from video 48 only 1 has turned out to be what is more than likely a wallaby . It's pretty obvious when you see it in the chart .
The new chart contains 3 wallabies at known distances and at known volumes . Ambience is taken into account to measure the distance of the subject however I've yet to find audio which is more than 4% different from the original recording of myself . For example , a subject who appears to be at 13 metres and after adding or subtracting the 4% only makes it's distance at 12.48 or 13.52 metres , so you can see , a small amount of 520 mm cannot be transfered to the chart .
The green columns are wallabies , the orange columns are myself and the blue columns are the unknown subject . The shortest columns are the heaviest impacts .
I understand some may have doubts as to whether this is accurate or legitimate but I can't see anything that I've missed , maybe you can .

The above video has the 1st subject in question and the charts below are named . Judge it for your selves .

The above video starts at the first unknown subject which is more than likely a wallaby .
The names of the pictures have the video times of the subjects .
