Audio porn, a buzzy new genre of X-rated erotic recordings, is the latest tool for intimate exploration — and the greatest, if you ask its flushed community of fans. Sexy startups like Quinn, Dipsea and Ferly are leaping off the popularity of podcasts and making major investments in listening pleasure. You can think of them as the Spotify of smut.

On Quinn, a free, YouTube-like website to which users produce and upload their own recordings, stars like Hank Miller serve up titillating content designed to tickle your ears and more.

“I can be as naughty as you want; I can be as dominant as you want,” he tells The Post.

Miller’s vibe is personal and participatory. In one popular track, he coos as an assured, seductive “daddy,” guiding the listener to a toe-curling climax in their sister’s guest bed. In another, tagged “Rough,” he’s growling as your obnoxious next-door neighbor, pinning you down for an aggressive encounter in your building hallway. In a gentler audio, he’s your super-supportive boyfriend, agreeing to a drunken three-way with you and a cute guy pal.

Miller, 55, works in machine maintenance by day. He records his erotica in his Ontario home studio, layering in suggestive sound effects and just enough detail to place the listener in the scene. Listeners have no idea what he looks like — if he has a ripped body or giant bulge. His stud status is all about the voice box.

“What I look like is up to you,” he says. “I can be anyone.”

And his fans like what they hear.

“This was so damn sexy,” a satisfied reviewer named Laura recently wrote of the daddy track. “Those beautiful, delicious moans!!”

Quinn, a Brooklyn-based company that launched this spring with a reported $1 million backing from Silicon Valley, aims to produce sexy sounds for a range of predilections. The content has a woke bent: Some traditional kinks, like incest and nonconsent, are banned because they’re problematic. Others, like spanking and voyeurism, are fair game. And then there are the audio-specific kinks — sexy voicemails, erotic ASMR and moan tracks. There’s even a tag for British accents.

“We have everything . . . all different stuff,” founder Caroline Spiegel says. “You might find yourself exploring content you never thought you would explore. And that’s one of the goals.”

Since June, Quinn has grown its user base 11% on average every week, and listeners now hail from 200 countries and territories, a company rep says.

Dipsea, another leader in the realm of audio porn, is a $9-per-month app that launched in December with $5.5 million in funding. Unlike Quinn, it operates as a self-contained content studio. San Francisco-based co-founder and CEO Gina Gutierrez oversees a creative team that crafts diverse, steamy stories (and related wellness audios) and disseminates them over a cheery, millennial-friendly interface.

Gutierrez says that sensual listening has its advantages over visual pornography.

“It can make you feel in touch with your sexuality without having to have it explicitly put in front of you, like, ‘These are the bodies, these are the people, this is the room that they’re in,’” she says. “It’s much more subtle. It’s much more intimate.”

Sex therapist Jesse Kahn, director of the Gender & Sexuality Therapy Center in Midtown, agrees that erotic audio can liberate listeners to unlearn narrow definitions of “sexy” that pictorial porn tends to perpetuate.

“Because audio porn doesn’t have visuals, it can create a different type of space for imagination and creativity, which can energize our inner sense of eroticism,” Kahn says.

That was the case for one local Dipsea user, a corporate diversity consultant who lives in Clinton Hill and prefers to remain anonymous. They tell The Post they’ve had mixed experiences with adult content in the past.

“I’m transgender; I’m nonbinary; I’m a queer person — there’s always a question of how inclusive these types of platforms will be,” the 36-year-old says.

But with Dipsea, they feel safe and seen.

“The spirit is one of curiosity and adventure, rather than, ‘Ugh, is this gonna be weird? Am I weird for liking this?’”

For a Quinn user, who also asked to remain anonymous, audio porn feels less “gross” than conventional adult sites, with their explicit ads and bouncing body parts. It’s also helped her articulate what she likes in bed.

“What you don’t get with visual porn is the language aspect,” says the 25-year-old hospitality pro, who favors British-accent recordings. “Quinn has made me more comfortable using words and just asking for what I want.”

The Dipsea user has gotten so into audio porn, they’re considering going pro.

“I was actually thinking about auditioning to be a voice actor,” they say. “I love it so much, I want to be part of this journey.”

Here’s what listeners are swooning to on Dipsea and Quinn right now.

“Eavesdropping,” Quinn

Your mom is throwing a party, and one of her guests — a sexy older man — takes a call outside of your bedroom. You get turned on spying on him. He catches you.

You let your longtime friend crash on your couch. By the morning, you’re more than just friends.

“Babysitter,” Quinn

You’re a babysitter, and the kids’ dad is late. He’s had a stressful night, and could use a drink — and some company.

A woman runs into her cute former boss at a bar. Professionalism’s held them back . . . until now.

A moaning lover whispers sweet nothings to you. Complete with sound effects.
