a 1-bit delay line? basically could be used to store audio-rate impulses, clocks, and triggers. the buffer would be a bitbuffer, so it would be a very memory-efficient. the notion of feedback some kind of feedback could be compelling too… #halfbakedideas #1bit

saw this great writeup once on how somebody visualized data by drawing faces with them, and letting our brain’s natural face feature-extraction algorithms interpret the data. Kinda want to try to do that with some of these samples and waveforms I’m curating. #halfbakedideas

This morning I had this really weird notion of building a generative podcast complete with musical interludes and asemic speech using a speech synthesizer. It’d be interesting to have “interviews” with two distinct vocal characters. #halfbakedideas

added @!(sndkitref “bezier”)!@ to !sndkit today. coupled with @!(sndkitref “oscf”)!@, it is capable of making some really weird wet FM-y sounds. Me like! #updates #sndkit

the c64 method would be an even cheaper video storage mechanism, but you wouldn’t get constant 2-bit color.

so, having the etudes be ~20mb/minute for sound AND video ain’t too bad, and that’s before doing any sort of compression. My etudes are almost always 80-120 seconds long, so the total size of a lossless uncompressed etude would be ~40mb, consistently. #halfbakedideas

sound for #breathingcard etudes in 44.1 kHz mono 32-bit floating point sound. that’s about ~10mb a minute raw uncompressed audio. #halfbakedideas

my #breathingcard etudes are 128x64 resolution videos with 4x zoom, that normally use no more than 4 colors (2-bits) using a 2-bit color storage format, that’s ~7mb a minute for raw uncompressed 60 fps video. not bad. #halfbakedideas

I’ve been thinking about storing the output of some of my audio-visual etudes in a more portable lossless 4-bit indexed color format, rather than rely on x264 directly. #halfbakedideas #etudes #breathingcards #longterm

well, I missed my one-year #twtxt anniversary by a few days. yay?

also hoping to bring bits of #sndkit into #9front and #neindaw. maybe build a whole professional-quality music production platform around plan9 concepts instead of the tired cliche of emulating analog workflows? #halfbakedideas

this morning I planned lots of #halfbakedideas for #sndkit in the near-distant future: a ROMpler with crossfading capabilities and optional input, and vowel formant filter, paired with a physical model of the glottis.

!caisaichoh

huh. it seems that dumping + gzipping a SQLite database can sometimes have better compression than gzipping the SQLite database directly. cool. #sqlite

A fragment of my !monolith program has been woven to a !weewiki from !worgle using !sqlite. Find it for now at [[/proj/monolith/wiki/][the monolith project page]].

well, it seems like I managed to automatically weave all the !literate_programming parts into a !weewiki! It’s not all that helpful yet though, due to the fact that pages have autogenerated names like ‘wm_000_0002’. A table of contents comes next…

so, I actually did throw out my Csound book last night. Tore out all the pages and recycled them.

here is how to build a classic table-lookup oscillator: !osc

being able to render TeX math equations to PNG files is pretty empowering, because it allows me to write about more technical things here that would otherwise be more difficult to communicate in plaintext.

figured out how to render a single TeX equation to a PNG file today: !render_one_equation

I never thought I’d ever say this, but I am officially done with Csound. I’ve been using Csound since I was 16 years old, but now I feel like throwing my copy of the Csound book in the trash. Good riddance.

an extendable text editor inside of a Blit that tries really hard not to edit text. #halfbakedideas

at the end of the day, I do like the stiffness of the tactile grey switches, even if it means I don’t get to type as fast, or as long. they just feel great to me. #mk

I rotate out my !planck keyboards weekly. going from brown switches to tactile grey switches is always a bit of an adjustment! #mk #thumpthumpthump

somehow get !weewiki pages rendered in !btprnt. maybe build a btprnt backend for links browser? #halfbakedideas

The master plan is to export the !worgle bits of !monolith to a !weewiki, then begin adding user-level documentation that is able to dynamically reference bits of source code as another wiki page.
