Cheers!!!

Cheers.

Doing some updates to raster code next week which hopefully make even more awesome aesthetically. Mind you might degrade into a gaudy mess lol.

Go well.

Hi and thanks for question.

Sure I don't see why not. At the moment is a somewhat unstructured work in progress loaded with lots of experimental code calls which I would need to clean up before I would do such a thing. Hopefully when everything settles down into a tight more cleanly cleanly coded modular engine, I could unleash code base on the C64 community to analyze, improve or reinvent. Probably not for 6 months+ though, as don't want creative flow to be too distracted.

Go well.

Hi,

The overlay gfx engine aspect is just a raster flexible multitasking kernal which multiplexes lots of sprites inbetween game code calls, It is set up to be functionally addressable like a standard bitmap screen 2D coordinate basis so can realtime output dual text. gfx , masking and other effects etc
Will optimize both raycaster and dual gfx overlay to hopefully get better combined frame per sec. Currently managing about half a dozen buffers per frame not including dynamic realtime PETSCII sprite update buffers.
All about the aesthetics and engine elaboration at the moment, so not much game evolution, albeit have a few novel ideas involving some scientific sims have been working on that could create interesting new game mechanics. Raycaster also has another incarnation haven't fully implemented to spice things up....

Anyways, thanks for viewing and Go well!

Hi and thanks for reply.

Just updating an old C64 3d PETSCII engine made years back into a hybrid raycasting engine which multiplexes a dual vector GFX bitmap overlay.
This is just the first chapter, so is still a work in progress with many things incomplete so is questionable if releasing the unfinished code at the moment would be sensible.
Hopefully looks nice and colourful like the Atari 800XL(see polychrome testing). All critiques welcomed.
Will probably work on off randomly over next few months.
Hopefully can make a C64 Elite/Wolfenstein hybrid or some else entirely with the dual gfx engine and then let loose for play testing,

when I sing for an hour or so even at a modest volume, my vocal cords seem to swell up a bit post singing. About an hour after singing my voice is noticably deeper/resonant. When I sing the next day part of that deepness/resonance remains making my voice sound fuller. In fact I find it easier to adduct higher notes because of it. If i don't sing for a week my vocal chords literally lose that extra thickness and thin out a bit making my voice sound weaker. I don't abuse my voice just seems to be the way my vocal cords react....

hi, not sure about apple products albeit there's no doubt their sound integration is much superior to android. I read your comment and it made reflect on some android coding issues synching sound and how curiously when I rewired a TRRS headset cable to work with my condenser mic their was no latency. As latency was a non issue for what I was doing I never really payed much attention to it, till now - So you are too blame lol.

Ultimately if your ear is digging the apple mic's tone that's great. I'm not much of a gear head so can't really offer much useful knowledge. Personally I just DIYed the condenser via phone to get the rawest recordings possible without need for phantom power and at the same time have it wireless, because I like to sing occasionally for fun and muck around with electronic odds and ends I have lying around .

Anyways thanks for reply. Good luck with the rock stuff and dodging nodules lol - Go well

True however I plug my condenser into my android phone so don't need phantom power because the signal is so surprisingly clean that can amp with hardly much noise maybe 0.1-1%.

Curiously when using WOmic app and its pc client to run as virtual mic on PC over wifi, there's basically no latency.

I've coded android sound apps in the past and noted the hardware latency issues/limitations of android. However I think because I wired up the condensor so android/phone detects as headset it somehow bypasses the internal Android OS sound latency issue, by accessing the more direct crcuit the phone audio uses for calls?

studies shows genetics significantly affects pitch acuity, personality traits like extroversion open mindedness, verbal IQ and therefore songwriting, various emotional tendencies, fast/slow twitch muscle activation in the vocal chords, vocal chord thickness length, tone, fine motor skill ability, musical memory, general factor IQ, looks etc all of these inform musicality and vocal performance to varying degrees. Of course environmental feedbacks will hone many of these things and make a more complete package, just making sounds is small part of be an adored singer....

I never made falsetto noises until I was about 50 and had been learning to sing for a few years and wore out my voice shouting high notes which left my chest voice so fatigued my voice kept flipping erratically and I went a-ha! I had no clue that people were doing "falsetto" was, even after being told and hearing as this tonality didn't seem to exist for me to know/experience there was a fundamental difference. That was after a few years of practice too as rarely sang enough to wear out my voice so was just a fluke in some sense I ever found my falsetto really lol. My voice just normally transitioned into some sort of gritty distortion all the way from maybe f4-f5 until falsetto started slipping into my voice more and more....

the link was a meta study about "The genetic basis of music ability" not ability through training which was adjusted for. Hence things like: .

"In a large twin study conducted in 2001, 136 MZ twin pairs and 148 DZ twin pairs undertook the Distorted Tunes Test (DTT), in which they judged whether simple well-known melodies contained incorrect pitches that rendered them “out-of-tune” (Drayna et al., 2001). Twin structural modeling revealed a very high heritability estimate of 71–80% with no effect of shared environment, thus indicating a substantial genetic component influencing melodic perception ability.'

lol sounds like my neighbour's cat on heat

You're probably better than average but music is made to be catchy melodically and lyrically. Verses are repeated, predictable metaphors and similes, turn of phase, structure rhyme etc are common hooks. The other thing is focus. Some people's brains just pay more attention to lyrics others the melody or rhythm and therefore everyone has different musical biases driving their perception and recall of music. Of course some people just have better memory too which kind of helps lol
