How would one go about determining what effect to add for each cassette type? I don't know much about cassettes, I'm curious if this was something that could be done by ear or if these are commonly held opinions about the sound of each tape.
Again knowing nothing about tape, if I were tasked with this I would probably try to record the same audio to each of the tapes and then compare it with the original.
Similar to how the different film stocks affected the look of the image, the different tape formats would effect the sound similarly. Crudely explained, the more light brown the tape, the more noisy it would be. The darker the tape, the cleaner it could be. If you like the sound of someone standing behind you constantly saying shhhhhhhhhhhhhhhhhhhh, then choose a brown tape.
By now, the audiophiles have lots of profiles of what the various tape formats would sound like. It's been ages since I've looked at audio plugins, but I would be shocked if there's not presets to make your pristine audio sound like a Maxell cassette that's been played hundreds of times.
There's great VST plugins like "Sketch Cassette 2" that will do hiss, flutter, all of that, along with some great presets. That one's less about creating authentic sound profiles, more like creating lo-fi tracks and instruments for music production.
Of course ! By the way, I'd love to see more HN posts about NAM. I've been following the project since day one, and it's been an absolute game changer for guitar amp modeling. It's genuinely exciting to see an open-source project have such a profound impact on the entire industry,not just modelers but software plugins and hardware solutions
> CHOW Tape is an analog tape machine physical model, originally based on the Sony TC-260. The current version can be used to emulate a wide variety of reel-to-reel tape machines. Feel free to build and use for your own enjoyment.
> CHOW Tape is currently available in the following formats: VST, VST3, AU, AAX, AUv3, CLAP, LV2, Standalone plugin
That's like all of the DAW/DSP plugin formats.
Hopefully BespokeSynth VST3/LV2/CLAP plug-in hosting on Linux w/ Pipewire will be stable for it.
I found ToobAmp, which has a Neural Amp Modeler plug-in and also "TooB ML Amplifier" Artificial-Intelligence/Machine-Learning-based emulation of a number of different guitar amps and overdrive/distortion pedals based on Jatin Chowdhury's ML Amplifier library"https://github.com/rerdavies/ToobAmp

Basically, on analog media, playback speed isn't perfect. There's constant speedups and slowdowns. This creates a "waa waa" or "wow wow" effect that's noticeable when playing a constant pure tone.
Has anyone come across a Dolby B (or similar) encode / decode program?
I've been wanting to experiment with quantizing Dolby (or similar) encoded audio to 8 bits, and then unencoding to see how well it can sound.

To which analog gain would 0 dBFS be mapped?
Can this be modeled with Neural Amp Modeler (open source) and Tone 3000 like a Space or a Pedal or an Outboard? https://www.tone3000.com/amalgamaudio

If you're interested in this topic, here are a few projects I found particularly interesting :
LTSpice Guitar Pedals : A collection of LTspice simulations of classic guitar pedals, useful for studying, modifying, and experimenting with analog circuits. https://github.com/cushychicken/ltspice-guitar-pedals
spiceAmp : An analog guitar amplifier simulator based on SPICE, designed to model tube amp circuits with high fidelity. https://github.com/olegkapitonov/spiceAmp

What is "wow"?
Basically, on analog media, playback speed isn't perfect. There's constant speedups and slowdowns. This creates a "waa waa" or "wow wow" effect that's noticeable when playing a constant pure tone.
don't forget that tapes also stretch so that can also give similar sounds
It's a kind of pitch instability: https://en.wikipedia.org/wiki/Wow_(recording)
Interesting! What tape simulation do you find yourself favoriting?
