my brain will never be able to process how this translates into sound, no matter how many times I read how it's done. it's fascinating as hell.

I can understand making the vibrations just fine, but the different tones/instruments/fine sounds, it's nuts.

The purple gooop is the soul of dead musicians

The needle follows the records track and wiggles up/down. The wiggles are translated via magnets into an electrical signal that runs through several stages of amplification until its audible. Get close and you can just barely hear the music from the needle itself

The grooves in the disc makes a needle vibrate. A microphone right next you the needle picks up the sound and then an amplifier and speakers increase the volume

A vinyl record works by converting physical grooves etched into its surface into an audible sound through a series of mechanical and electrical transformations. Here's how the process works: Recording Process: Sound Waves to Grooves: The original recording is captured as sound waves, which are then converted into an analog format. These sound waves are used to cut grooves into a master lacquer disc with a cutting stylus. The depth and shape of these grooves correspond directly to the waveform of the music. Playing Back the Record: Spinning the Record: The vinyl record is placed on a turntable, which rotates it at a constant speed, typically 33 1/3 rpm for LPs or 45 rpm for singles. Stylus and Grooves: The needle (or stylus), usually made of diamond or sapphire, is positioned in the outer groove of the record. As the record spins, the stylus moves through the grooves. These grooves are actually a continuous spiral, with varying distances and depths that represent different sound frequencies and amplitudes. Vibration to Electrical Signal: The grooves cause the stylus to vibrate, mimicking the original sound wave patterns. These vibrations are transmitted to: The Cartridge: This is where mechanical vibrations are converted into electrical signals. Inside the cartridge, there's a small magnet and coil system. The vibrations of the stylus move this magnet, which induces an electric current in the coil. Alternatively, some cartridges use a piezoelectric crystal which generates an electrical charge when compressed or expanded by the stylus movements. Amplification: The electrical signal from the cartridge is very weak, so it needs to be amplified. It's first sent to a preamplifier (often built into the turntable or an external component) which boosts the signal. This preamp adjusts the signal to match the RIAA equalization curve, compensating for the initial recording process where bass frequencies were reduced, and treble frequencies were boosted. Sound Reproduction: The amplified signal is then sent to a power amplifier, which further boosts the signal to drive speakers or headphones. The speakers convert these electrical signals back into sound waves, using a diaphragm that vibrates with the electrical impulses to recreate the music in the air. Why Vinyl Sounds Different: Vinyl records produce an analog signal, which some listeners describe as "warmer" or more "authentic" compared to digital formats. This is due to several factors: Analog Fidelity: The continuous nature of the grooves allows for a very high resolution in sound reproduction, capturing minute details in the music. Surface Noise: Vinyl has inherent noise from the physical properties of the material and the playback process, which can add a texture to the sound that some listeners prefer.

So on a record the needle sits on a physical imprint of the actual Soundwaves.

This isn’t the whole process. The grooves haven’t been made yet

Same. I still can't understand live tv or how tv works

One of the most mind blowing experiences I remember having as a kid was when I decided, out of curiosity, to put the needle and turn the disc by hand with the machine turned off, and I could still hear the song, at a very low volume, but I could clearly hear it.

Anyone else disappointed the record wasn’t the song they were playing?
