Adjustable octave warble tone generator

percy · 25th August 2009, 08:56 PM

Does anyone of a (free) software tone generator that will let me select not just the frequency of the warble tone but also how many octaves. Typically its 1/3 octave, but I'd like to use smaller octaves like 1/6th, 1/24th...

Do you know the Crawford Warble Oscillator published in Audio Amateur (many) years ago? Hardware....

No I dont, but I googled it up and found a couple of references. It was published in AudioXpress in '79, by Dick Crawford. http://www.audioxpress.com/bksprods/products/pcbk-3.htm

Is this the one ?

I wish there was some more additional information available. What kind of octave spread adjustment does it have ?

While searching for this I also happened to run into another interesting device made by the same author - http://www.audioxpress.com/bksprods/products/pcbc-6.htm .

Speaker Workshop to the rescue!
good ol' SW has a signal generator that can do warble tones and will let you adjust the range!

OK, I was going to dig out my AA's but it seems you've served well already!

Burn a CD with warble tones, generated with Cooledit or something? Or there's some test CDs that have warble tones or band-limited pink noise. Denon Audio Technical CD, for one. If it's out of print, evil people may have shared it as a torrent or something. There's some freeware audio test CDs too.

If you burn them as MP3s, an MP3 player would display the name (so you wouldn't need to count tracks on a CD player). A small (32M) (obsolete) flash player should be more than enough space.
