unfortunately the cylinder is REALLY limited in frequency response, basically the same as a battery powered cassette tape recorder. 200hz to 4,000hz with a few transients in the 5,000hz range, but deaf to anything above that, bass is limited as this is an acoustic recording, the diaphragm is glued d...

this is an mp3 transfer to an original 1920 brown wax columbia recording blank, playing through a guitar amplifier, this sounds like a tape recorder !!!

experimenting with a new recorder, this is a transfer from a 78 rpm disc recorded on a 1920 brown wax recording blank. this blank has an anomaly in the wax so i use these for doing test recordings. this is recorded at 160 rpm.

the museum had this machine overnighted to korea. the crate and machine weighed in at 85 pounds. this will be in the museum day after tomorrow. this is a delicate machine made almost entirely of wood, it has a long way to go. i spent 4 weeks working on this machine. i am biting my nails hoping it wi...

the machine will be leaving in the next few days. had the crate built and will be packing the machine in the next day or so. the museum asked me to make a series of recordings to be left on the mandrel, so will be doing the final recordings tonight probably. to my knowledge no one has ever recorded ...

this will leaving first of next week for the museum in south korea. it was a privilege to be able to work on a phonautograph, i will never see another. there was only one working phonautograph in the world in a museum in France, now there are two. a challenge and a lot of fun. this is going to be a ...

a very special day. i have been working on this machine for weeks, this is going to the national museum of south korea. i just got the machine completed today and am doing a series of experiments. this was the first machine in the history of the world to record sound, it cannot reproduce it, but it ...

i found a box of 50 original 1920 recording blanks, these are deep chocolate brown unlined recording blanks made by Columbia. until 1906 columbia bought all of its recording blanks from Thomas Edison, Edison said " your going to have competition anyway, why not make a profit at it" . these are reall...

built the new stylus, stylus holder, new gaskets and diaphragm, used a 400hz tone for the first test and got some feeble modulation on the paper. i need to smoke the paper to actually test how well this will work. the machine is recording sound... -vTcc5O28lI 1857 phonautograph / first recording Tes...

20 years before Edison recorded and reproduced sound eduard leon scot de martinville constructed this machine to trace sound waves on to blackened paper. the stylus would scribe a lateral modulated line into the paper as a waveform, this allowed you to actually "see" sound waves, much like a modern ...

recorded on a 92 year old dictation machine that has been modified into a 6 minute cylinder phonograph. this is an ACOUSTIC recording playing through a walmart transmission funnel...

rebuilt recorder with "new" stylus. the recording stylus on these acoustic machines is a cupped tip sapphire rod .031" in diameter. over the last 90 years these styli become dull and no longer engrave the wax, this is a vertical cut format. i heated the stylus holder with a soldering iron, this soft...

an experiment that worked...

still not perfect but getting better, this is the first cylinder recording blank that is not based on the original Edison aluminum soap formula. the blank is completely synthetic, non toxic and does not require 400+ degrees with 5 hour cooking time, this is melt and pour, once i get this perfected i...

THERE IS NO LEAD IN EDIPHONE OR DICTAPHONE CYLINDERS, I PROVED IT !!! same crap over and over, people publishing bullshit rather than doing a real test, real testing cost money, bullshit is free. i tested every dictation cylinder i have, nuphonic, edison, standard. NONE OF THEM CONTAIN LEAD. you are...
