Nixie tube audio spectrum analyzer
Electronics enthusiast and developer Juergen Grau has returned to Kickstarter for 7th time to launch his new Nixie tube audio spectrum analyzer. Watch the demonstration video below to learn more about his latest creation which is now available priced from €149 or roughly £134 and is fitted with six unique Nixie tubes to display readings.
“So Mr. Nixie has taken the EM800 Magilyzer and the former Nixielyzer kit, which is sold out, put them in a pot, added a hefty dose of the legendary Mr. Nixie Magic, and finally a new kit, the IN-9 Nixielyzer was created. The IN-9 Nixielyzer now separates this audio signal into six selective bands and show their special audio level within this frequency range:
#8211 63 Hz = Low Bass (e.g. Bassdrum) #8211 150 Hz= Mid Bass (e.g. Bassguitar) #8211 330 Hz = Low Mid (near concert pitch of the most musican instruments) #8211 1 kHz = Mid of voice frequency (e.g. the #8220beep#8221 sound for indecent words in interviews) #8211 3.3 kHz = Presence (e.g. #8220sch#8221 in the word Schedule or the imitated sound of a steam locomotive) #8211 10 kHz = Heights (e.g. #8220sssss#8221)
“And as an absolute unique feature, the IN-9 Nixielyzer displays the level not on #8220ordinary#8221 LED display or VFD display or on a computer screen or even in an App of your mobile phone but on six IN-9 Nixie Bargraph tubes made as surplus in the end of the 80#8217s in USSR.”
