Behold:

https://www.researchgate.net/figure/Electrical-conductivity-of-banana-at-different-ripening-stages-with-the-help-of_fig5_317486785

5.4 Electrical Conductivity Measurement This method includes electrical impedance spectroscopy (EIS) and dielectric analysis (DEA). The physical state of a material is measured as a function of frequency in EIS and the frequency ranges from 100 Hz - 10 MHz. It is simple and easier technique used to estimate the physiological status of various biological tissues49-52. Experimental frequency response of impedance is characterised by electrical equivalent circuits of materials. The physical properties of materials can be quantified by monitoring the changes in parameters at the equivalent circuit, among various equivalent models proposed53-54. DEA measurement is used in high frequency areas, generally 100 MHz - 10 GHz. DEA is used in moisture estimation and bulk density determination

So a overripe banana is an interesting high-pass filter, kinda like a capacitor, though the big takeaway is the conductance vs ripeness.

So if you want to test if a banana is ready to eat, hook it up… preferably with several other bananas in series. If the music is too loud, they are ready. Too quiet, and it’s not time yet.

The moment you give me a link to a banana tree/MP3 player/ripeness tester/EQ:

I only listen to music with overripe bananas. It sounds best that way. Copper wire just doesn't sound as good. Believe me: My ears are very sensitive and superior to yours.

You get much better conductivity with plaintains because the cross-sectional area is bigger.

But because my ears are so discerning, I only put my audio jacks in jackfruit.

Most people can’t tell the difference between a 320kbps mp3 and lossless, but hey if folks really want to waste their money on snake oil like gold-plated cables then I say let ‘em.

[–] Elgenzay@lemmy.ml 3 points 2 hours ago

Reminds me of the lengths people go with their peripheral purchases to save 1-2ms of input latency for playing games with like a 20 TPS tick rate on a wifi connection

At that quality of MP3 you'd really need either a track that specifically pushes the limits of the codec on technicalities, or a one in a million hearing + high precision monitors.

Albeit FLAC is generally a better option still because it compresses things losslessly, reducing raw file size 50-70% (comparable to MP3 at 128kbps bitrate) and is a royalty-free, meaning it can be freely implemented as a hardware codec.

For example, a bunch of microcontrollers in the ESP32 family have built in FLAC codecs that outperform their MP3 counterparts, meaning a FLAC library can be directly streamed to them, and with the right DAC combo, one can build inexpensive, low power adapters to hook their existing AV systems up to Sonos-style streaming. And with many AV systems supporting bidirectional RS232 (or other serial) communications for controlling the system and querying it's state, you can literally smartify them completely AND provide high quality audio streams to them.

I'd be surprised if anyone could.

However, 128kbps vs. 192kpbs+ is like night and day, and it's especially obvious with better equipment.

People who say 128kbps mp3 is fine, are full of shit. I've been to weddings where it's been so obvious that whoever's in charge of the music is just blasting 128kpbs mp3s and it's brutal.

The funny thing is that the people who can afford all that overpriced garbage are usually so old, they can't hear all that well anymore.

I did a blind test, and found it depends on the genre.

Slow, chill music is completely transparent when compressed, no matter how hard I “audio peep.” It’s not even a question.

But something “dense” like System of a Down has audible distortion. It loosely (not always) coincided with the bitrate of the flac files, which kind of makes sense, though even the extreme end is hard to notice unless you know the particular song very well.


Also… a lot of recordings kind of suck. It’s crazy to worry about tiny bits of distortion when a bit perfect master is already noisy and distorted.

I listen to QUAD 77-11L speakers from like a lifetime ago, and a cheap class-D thing from Aliexpress. It's fine.

[–] SreudianFlip@sh.itjust.works 12 points 3 hours ago (1 children)

HugeNerd is correct, 90+% of audio quality is in the mic and speakers. Transducers make electro acoustics real, everything else is support.

Get really great used speakers cheap and an adequate amp just good enough to drive them. Your shit will sound excellent for anyone.

[–] HugeNerd@lemmy.ca 5 points 3 hours ago (2 children)

Well, I'd argue the placement and room are an integral part of it as well.

But did they use oxygen-free copper (OFC) wire? Because otherwise the results are skewed as regular copper sounds just as bad as a banana stuck in wet mud.

[–] HeyThisIsntTheYMCA@lemmy.world 5 points 3 hours ago

i'm into oxygen free listening lately

Audiophiles get a lot of friction, but this kind of person exists in almost any hobby. People fascinated by equipment and ascetics who loose the plot about what their hobby is all about.

[–] klymilark@herbicide.fallcounty.omg.lol 21 points 5 hours ago (1 children)

Or wet mud

Does dry mud exist? I'm pretty sure we just call that dirt xD
