10:50 <@scottvr> someone with the ability should do me a favor.. remember the tone
	     progression  (beeps and boops) that you'd hear as the leader 
             tape spooled on a CrO2 cassette tape back in the 80's?
10:51 <@scottvr> I want those tones.. if you have a tape deck and a cromium dioxide
             store-bought tape, and can digitize that 'boo boop boop beep boop'
             sound for me, I'd appreciate it
11:00 <@scottvr> i can't even find a reference explaining the frequencies and
             durations of the beeps.. I am not opposed to generating sine waves
             into a wav file, I already have code to do that for dtmf
11:00 <@scottvr> but since my googling fails, I suspect finding someone to record
             it for me will be the only way
11:06 <@cz-h> i have a tape deck
11:06 <@cz-h> but uhh
11:06 <@cz-h> tape deck -> digital is another matter
11:06 <@cz-h> and right now it's time to go find brenden a basketball hoop
11:08 <@Channone> bleh
11:08 <@Channone> need change for laundry
11:09 <@scottvr> you know the beeps I'm talking about, right? I think they were
             auto type selector or something and iirc, you only heard them if
             playing a cro2/type II tape on a regular fe tape deck
11:11 <@cz-h> i know the sound
11:14 <@scottvr> well, at the end of my latest track
             (http://killsignal.net/~scottvr/selfdestruct-firstdraft.mp3) I've sampled
             the sound of a non-auto-returning record stylus sitting in that
             last groove on a record
11:14 <@scottvr> so, at the beginning of the cd, I want that cro2 beep sequence
11:16 <@scottvr> ok well, I've found that the auto tape selector was based on the
             holes in the top of the cassette
11:25 <@scottvr> ok one usenet post form a guy saying he still has his copy of
             Synchronicity and that he always thought the beeps were an
             uncredited bonus track
11:28 <@scottvr> damn I'm good and damn this was the hardest reference search I've
             ever encountered
11:29 <@scottvr> googling for
11:29 <@scottvr> CCIR NAB IEC AES tones
11:29 <@scottvr> is what I needed
11:29 <@scottvr> gee.. shoulda been obvious
11:56 <@scottvr> ok.. so the specific ones I want are most likely XDR

11:56 <@scottvr> "11 tones, .175 seconds in length, each on octave apart"
11:56 <@scottvr> doesn't tell me *which* note
11:57 <@scottvr> hmm
11:57 <@scottvr> ok ok ..
11:57 <@scottvr> cro2 dynamic range is  20~17000 Hz
11:58 <@scottvr> so then 20,40,80,160,320,640,1280,2560,5120,10240,20480 would have
             to be it!
11:58 <@Oxf10d> success!
11:58 < ubu> success is, like, not the key to happiness
11:59 <@Oxf10d> one day ubu, I'm going to kill you
11:59 <@scottvr> well, now I gotta write out 11 sine waves of .175seconds each
11:59 <@scottvr> but that will be trivial compared to finding this information :)
12:24 <@scottvr> haha.. kickass

12:26 <@scottvr> boy howdy, the hardware, and most certainly the headphone speakers
             of today sure have better range than the tapes and decks from back
             in the day
12:26 <@scottvr> I can hear all 11 tones :)
12:52 <@scottvr> err.. not anymore
