"THX audio test" -is music, or is not music?

[Opcom]

"THX audio test" as in the AM vault here. What are the opinions as to whether this is considered "music" (to include other prohibited transmitted sounds in the rules)

Not music - there's no melody. It is harmonious modulated tones, but lacks necessary elements of music.
Not intended to attract attention to oneself - it is a test signal as opposed to something like a 'noise toy' sound that is usually repeated many times.

It is a good measure of the subjective transmission path from speech amp input to the receiver's speaker.

I've never heard it used. The user would have to have a huge signal to do it right.

The sound as presented is two channels. Should those considering sending or receiving it use C-Quam or ISB? Two channels either way would be a challenge. Maybe stereo is a bad idea but someone did put it there.

I think you're safe, unless you come up with some lyrics and leave the mic open while it plays.

My main audio processor, the K06NM "DAP 610," has a built-in pink noise generator for testing and setup. Mike designed this processor along music theory, and maybe the tones produced could be considered musical, too.

This website provides audio files as examples and a brief descriptions:

Pink noise is similar to white noise, it also contains the wide range frequency signal in the spectrum. It is commonly found in nature environment. Unlike white noise, listening pink noise is more comfortable. The sound is quite similar to ocean. Some people play it in the office for relaxation and concentration.

What passes as "music" these days is totally subjective anyway.  Ever twirl through FM radio?

How do you access it?  I clicked on the link in the upper left-hand "On AMfone" box, and got this error message:


! Error !

Sorry
You are not authorized to access this area

What do I have to do to become "authorized"?  All the other links worked.

This older IE Browser at work had to install some sort of add-on to play it.

Works FB with the right plug-in.

That file will make your head spin around if you turn it up loud, especially with headphones on!

Wants to add a Windows Media Player extension. You get the "add-on" message with any version of Firefox (including the latest Version 8 ) and any version of IE unless you have the plug-in already installed.

An excellent way to see if your modulator overload relays are set just right!

Sounds like a bunch of square waves to me, but I haven't looked at it on a scope.

Same error message.  I use Firefox.  What plug-in do I need?

[kb3ouk]

that sounds more like a problem with the site itself, not the browser.

[k4kyv]

I copied and pasted the URL into IE and tried it, and it worked.  Must be a plug-in problem with Firefox.  I'm using the older version of FF: 3.6.23

Maybe the Latest and Greatest would work?

Back to the topic, regarding the "music", the audio clip sounds like something I would hear on "Hearts of Space".  

The definition of music lies in the ears of the beholder. What about singing, without instrumental accompaniment? That's nothing more than a matter of intonation of the voice. I could sing the words like Sinatra used to, chant like a monk, or speak them with a Jamaican, American Black or Irish accent; it's still the same thing, spoken words and the intonations you use with your voice. Who's to say that one is "music" and the other is not? Ever notice that singers, when they are not deliberately trying to put on an obvious "accent" (e.g. country music singers, blues singers and Kevin Bloody Wilson), all sound about the same whether they hail from Nashville, UK or Mid-America?  I remember a disc jockey back in 1963 who observed that the early Beatles recordings sounded just like the Liverpudlian vocalists were right out of Vicksburg, Mississippi. It's all a matter of the "melody" one uses with one's words. When one sings, the melody of the song replaces the melody of the native accent.

The same goes for sound effects and test tones.

I'm using FF 3.6.24, and it works for me.

[k4kyv]

I upgraded to FF 3.6.24 and still get the same error message.

Mine plays it in the quicktime plugin.
firefox 3.6.13
quicktime plugin 7.6.9

I think you're safe, unless you come up with some lyrics and leave the mic open while it plays.

Mr. VUs' rendition of that cheerful tune of the season, 'Ding, rice are done'..
Without accompaniment, is that music?  I don't consider it music -singing a capella seems exempt when part of a QSO.
Don't worry, I will never be singing into the mike except in an emergency!

Reading and understanding is important.

In Firefox, go to Tools (it's at the top), click it on, and check your "Add-ons" to see what plug-ins you have or don't have, enabled or disabled.
In I.E., go to Tools ( it's at the top), click it on, and check your "Manage Add-ons" to see what plug-ins you have or don't have, enabled or disabled.

For this Audio Test software activity, browser stuff Tools-Add-ons is a don't care for Firefox and I.E. The software is looking at your Windows Media Player, or whatever your media playing software is, for the proper plug-in.

Ding! Lice all done.

Testing the ole AM transmitter out.
OK in a dummy load.
The Feces prohibit even a test tone on the air.

An Aside note:
No Money Mike, KO6NM is a genius. And a helluva guy. Too bad he invested so much money on the Short wave station for the blind and was over ruled by crooked lawyers.

The THX clip played fine here.........FF used.
And it sounds great on a surround sound system with woofer.

I have done the THX test on a dummy load before useing a mp3 player in my transmiter see how much low end the transmitter will pass and high end was pretty cool watching on the scope cause seeing and hearing at same time was like wow!! there's more there then my ears can hear!

Where in Part 97 does it say that?

As I recall, when they prohibited music for "test purposes" some time in the late 1930s, they added a provision that simple tones were legal for "brief" tests. That leaves it open to interpretation what is music and what is a "simple" tone, and how much time it takes to exceed "brief".  Are two-tone slopbucket tests illegal? What about slopbucket "peckers"?

[N8ETQ]

  Quite True, Anyone up for a little "MCW" ?  Like everything these days
it's "Subjective" = "open to interpration" = "Who gets pissed off" = "who do they know who can Screw U"? Were a country of laws that can only be translated by our elected "inferiors". I think Plato mentioned something about that.  OTOH I'm always amazed to meet "Long time Ham's" who don't even
own one.

  I couldn't make it a day without my 3.
