Can magnetic core memories be used to process audio signals?
Edit
This question is in relation to another question I asked previously -
"Does magnetic flux density have a measurable tonal characteristic in audio?"
(feel free to answer this as well if you'd like to, plus it explains why I am interested in the possible use of this technology. Just click my name to see my other question on my page)
So, THIS question is-
Can magnetic core memories be used to process audio signals?
Question expanded is, Can magnetic core memories be used to process audio signals in terms of voltage throughput, and if so is it possible to control the adjacent magnetic flux behavior of a single 'stream' or path of throughput (audio path) voltage stream by using the nearby and directly adjacent core groupings?
If you know what I am driving at here then give me a sign:)
My purpose for researching this has entirely to do with gaining a better understanding of magnetic flux behavior as it relates to audio. I am working toward something big for audio that I'd rather not go into detail about, but it relates to how MEMS can be integrated with analog and digital components to achieve a far superior tone generation resource for music and audio HIFI playback systems using digital purely for controls and data storage and acquisition.

Best Answer: When you say 'tone generation', are you talking about DAC or amplifier?
In any case - that answer to your question will depend on the internal structure of your 'magnetic core memory'. The only magnetic core memories I remember went out of fashion with the invention of the RAM and ROM cells and field effect transistors, so you'll need to be a bit more specific.
Usually, though, memory systems are built to minimize the effects between adjacent memory cells, sou you'll be looking at low-level side effects.
Otherwise, you seem to be talking about either hall effect or field effect transistors.
As to your other question about magnetic flux density and tonal characterisitics - that depends on how you set up the connection between the magnetic flux and the audio (which is, after all, just moving air). As long as you keep within the linear part of the magnetization curves of whatever material you are talking about, there should be no influence on the tonal characteristics. Leave the linear region, ad the influences can become quite drastic - as usual.
If you want to go deeper, dig into the design of valve amplifier output transformers.

No, the magnetic flux takes the form of an S shaped Hysterysis loop. Digital only.- It's been a while since I asked this question and I really appreciate the answers. They have helped me tremendously. In my question and statements I didn't really get into the intended purpose for using magnetic core memory in an audio related circuit. Markus pointed out that by staying in the linear part of the magnetization curves there should be no influence on tonal characteristics. And that leaving the region could have a drastic effect. My goal is to better replicate the much desired tonal characteristics found in discrete transistor and vacuum tube circuitry of electronic, electromagnetic, and electrostatic Musical Instrument tone generation circuitry ( analog electronic organs and synthesizers).
FET's ( field effect transistors) in guitar amplifier designs are a good example of one such method for better replicating vacuum tube characteristics, but without the bulk, heat, power consumption, fragility, and expense of physical vacuum tubes. FET's are close, but no cigar when it comes to precisely achieving the same tone, overload clipping (desirable in tubes for guitar,organ), and dynamic response of a real tube. However, FET's brought to music their own unique variations on these particular desirable qualities even if they weren't ideal substitutes.
As a musician with 38 years playing electric guitar ( AMPLIFIERS with tubes, transistors, and a modeled versions which are sub par in person), and 18 years now playing electric TONE GENERATOR based organs ( Hammond discrete tone wheel, Wurlitzer electrostatic reed, Conn fully vacuum tube, Gulbransen Master oscillator IC , and Hammond discrete transistor), I have a deep understanding of what makes for a great sound in terms of tone and response. Bottom line is that in a live situation where the musician relies on the most minute detail of their 'sound' as much as the obvious details ( actually minute details EVEN MORE because these are what inspire and push the rest of the music) emulation falls short. Now you might beg to differ. Most engineers do, but fact is that the better products were those in which real musicians were brought in during R&D and stayed throughout the engineering. The best example of this is the Hammond X66 organ. Musicians were given full credit for it's sound and features due to their constant involvement. Also the cabinet design was an art contest in which the winners were given very top awards for it's very unique highly futuristic, yet timeless appearance.
At any rate, I seem to be the only person I know of that is doing what he can to take tone generation to the next level, realizing the great importance of taking advantage of the organic nature of what makes for a perfect tone and bringing it accurately as a PARTICIPANT in the field of microelectromechanical, electromagnetic, and electrostatic systems for serious professional musical instrument technology.paulj0557-vacuum cleaner expert · 1 sec ago
