[ 01 ] // The opportunity

People who make edits
from their own song files

Changing a song’s speed and pitch is now an ordinary way to listen and post. Nightdrive is for the people who make those versions themselves and want a finished file at the end.

Listeners with no audio experience

You like slowed and sped-up songs and have never opened audio software. Basic is four guided steps: add a song, pick a sound, adjust six sliders, download an MP3.

People who have recorded or mixed

You want every effect with exact values, in and out points, presets you can save, batch export, and loudness and true-peak control. That is the Advanced studio, and every value can be typed.

Edit makers

You need several versions of one song fast. One export gives you four: slowed + reverb, super slowed, sped up and nightcore, each keeping your trims and fades.

Independent artists and small labels

You own the masters and want official slowed and sped-up versions of your own releases. The alternative today is doing each one by hand in a recording program.

Sleep and study listeners

You want a long, calm version. Nightdrive can extend a song to 10 or 30 minutes, folding the reverb tail onto the start so the seam is clean.

Anyone who would rather say it

You know what you want it to sound like and not which sliders make it. Highbeam takes a sentence and builds the effect chain.

[ 02 ] // The product

Three ways
to make a sound

Basic for people who have never touched audio software, Advanced for people who have recorded or mixed before, and Highbeam for anyone who would rather say it in words.

Basic

Four guided steps

Add a song, pick a sound from twelve tiles, adjust six sliders, and download an MP3. Slowed + Reverb, Sped Up, Nightcore, 8D Audio, Bass Boosted, Super Slowed, Lo-fi, Phonk, Another Room, Underwater, Concert and Sleep.

Speed, Pitch, Reverb, Bass, Tone and 8D surround
MP3 at 320 kbps, loudness matched

Tap a sound while it plays

Recorded in the app.

Highbeam

Describe the sound you want

Type what it should sound like and Highbeam builds the effect chain. Then keep talking to it while the song plays: “less reverb”, “more bass”, “first 30 seconds”, “make 4 versions”, “undo”. Save the result to My Sounds with the whole chat, and use it on the next song.

[ 03b ] // The sounds, in detail

Twelve sounds in Basic,
each there for a reason

The presets came out of a review of 14 consumer tools and of how people make, name and search for these edits. The top twelve are the tiles in Basic. All 26 are in the Advanced studio.

Sound	What you hear	Why it is in Basic
Slowed + Reverb	Slower and deeper, with a dreamy hall echo	In every one of the 14 tools reviewed. The style dates to 2017 and surged in 2020 and 2021.
Sped Up	Faster and brighter	Labels now release official sped-up versions of their own songs.
Nightcore	High, fast and hyper	In about 10 of the 14 tools reviewed.
8D Audio	The song circles your head. Use headphones	Common on video sites since 2016 to 2018 and still widely made.
Bass Boosted	Bass that hits hard	A preset or a headline control in about 8 of the 14 tools.
Super Slowed	Extra slow, heavy and huge	A standard label on phonk uploads.
Lo-fi	Warm, dusty and calm	Among the most common genres in study and sleep playlists.
Phonk	Dark and gritty, made for edits	Splice and MIDiA report that phonk reached the mainstream in 2025.
Another Room	Muffled, like music through a wall	The “song playing from another room” edit, a format since 2016.
Underwater	Deep and blurry	A standard variant of slowed edits.
Concert	Like hearing it live in a stadium	Apps that add stadium and arena sound have an audience of their own.
Sleep	Soft, slow and calm for bedtime	A 2023 study of 985 sleep playlists found sleep music is quieter and slower, and much of it is familiar pop.

Preset research, November 2026. Trend notes are from third-party sources cited in that research.

The rest of the 26 live in Advanced, among them Slowed + Bass, a sped-up version that keeps the vocal in its original key, Late Night, Chopped & Screwed, Daycore, Vaporwave and a 432 Hz retune. Any preset is a starting point. Change a value and save the result as your own.

[ 04 ] // Architecture

Everything happens
on your device

You bring a song and say what it should sound like, with a tap on a sound or a sentence to Highbeam. Highbeam’s model runs on your device and turns the words into an effect chain: tempo and pitch, tone, reverb, 8D and a limiter. You hear every change live, while the song plays.

The result goes where you want it: exported in five formats, saved to My music as a new version, or kept in My Sounds with the whole Highbeam chat. Your original file is never changed, and a shared sound is a link with the settings only, never the music.

Architecture

[ 04b ] // How it works, step by step

One effect chain,
live and in the export

What you hear while the song plays is what you get in the file. The export renders the same chain, in the same order, then sets the loudness.

Module	Order	What it controls
Tempo and pitch	1	Speed up to 2×. Pitch can follow speed or move on its own, so a faster song can keep its key. Tuning to 440, 432, 444 or 528 Hz.
Tone and EQ	2	High and low cut, bass, and an equalizer for the bands in between.
Texture	3	Saturation, bit crush, tape wobble and vinyl noise.
Echo and chorus	4	Echo that can lock to the beat, and chorus.
Reverb	5	Room, Hall, Plate, Cathedral or Shimmer, with a low cut that applies to the reverb only.
8D and width	6	Stereo width and the 8D pan that moves the song around your head.
Output	7	Compression, gain, fades and a limiter with a ceiling you set.

Loudness at the end. After the chain, Nightdrive measures the loudness of the whole result, sets the gain to the target and holds the peaks under a limit. The default is −14 LUFS with a true peak of −1 dBTP, in Basic and Advanced alike. In Advanced, Check loudness reports the level and true peak before and after.

How Highbeam understands you. Highbeam knows sound words and commands from a built-in Sound Bank. A model on your device helps with words the bank doesn’t know, and it can only pick from that bank. An off-topic request changes nothing. Undo takes back the last reply exactly.

From words to exact values. Fine-tune opens the Advanced studio with the settings Highbeam chose. Change them by hand, and the changes carry back into the Highbeam session.

[ 04c ] // What makes it different

The parts a speed slider
doesn’t give you

Use only part of the song

Drag two handles on the waveform, or tap First 15 s or First 30 s. Start and end times show as you move them, and Play this part lets you hear the cut before you save it.

Four versions in one export

Slowed + reverb, super slowed, sped up and nightcore from one song, keeping your trims, fades and length.

Several songs at once

Queue songs in Advanced, apply one preset to all of them and export the set. Songs with the same name are kept apart.

My music

Keep songs and every version you make of them in one place: search, favorites, and a main version for each song. A song that is already there is skipped when you add it again.

My Sounds

Save a sound from Highbeam with its whole chat. Rename it, edit it, use it on another song, or set it as the sound every new song starts with.

Same settings, same audio

Reverb and noise are generated from fixed seeds, so a sound you saved gives the same result the next time you use it.

[ 04d ] // How it is tested

A gate every build
has to pass

Nightdrive runs as two separate apps: a development build with its own test data, and the release. Nothing moves from one to the other without passing the gate and an explicit approval.

Test the installed app

An automated end-to-end run drives the installed development build with no window and no sound: every screen, the checks written for that change, and whether data survives quitting and reopening. The current build passes 63 of 63.

Check what is clickable

A screen’s text being present does not mean a person can use it. After every screen change the tests check that only that screen is showing and that its controls are the ones under the pointer.

Verify the release

After a release, a read-only verification runs on the released app, including real playback. The latest passed 25 of 25. A backup is taken before every release so it can be rolled back.

Highbeam has its own tests. They cover whether the Sound Bank is valid, whether requests are understood, safety, limits on every value, exact Undo, a round trip through a shared sound link, and 10,000 hostile links.

The library is tested at size. A test fills My music with 10,000 songs, scrolls, jumps to the end and searches. The measured median frame was 8 ms against a 20 ms limit, and search took about 200 ms against a 1.5 second limit.

The review panel was simulated. Ten simulated personas, five new to audio and five experienced, reviewed real screenshots of the build. They are not real users. Nineteen of their findings are fixed.

→
FixedSaving looked the same before and after. There is now a clear saved message
→
FixedChoosing part of a song showed no times. It now shows start and end, and plays the part
→
FixedA preset name read as an artist’s name. It is now Another Room
→
FixedLoudness defaults differed between Basic and Advanced. Both are −14 LUFS
→
FixedThe tempo was approximate and fixed. It can now be edited, halved or doubled

[ 04f ] // Questions people ask

Before you
ask about the beta

Do I need to know anything about audio?

No. Basic is four steps: add a song, pick one of twelve sounds, adjust six sliders if you want to, and download an MP3. Or type what you want in Highbeam.

What can I say to Highbeam?

Describe the sound, then keep going while the song plays: “less reverb”, “more bass”, “first 30 seconds”, “make it 30 minutes long”, “add a fade”, “make 4 versions”, “not that”, “undo”, “start over”, “save”.

Will it change my original file?

No. Originals are never changed. Every export is a new file.

Does my music leave my device?

No. Nightdrive runs on your own device, Highbeam’s model included, and your files never leave it.

What do I get at the end?

An audio file. Basic gives you an MP3 at 320 kbps. Advanced exports MP3, WAV, AIFF, FLAC or M4A, one song or several, with the loudness matched to the target you choose.

Can I reuse a sound on another song?

Yes. Save it to My Sounds and use it on any song, or set it as the sound every new song starts with. Using it on another song makes a new sound, so the first one is never overwritten by accident.

Can I send a sound to a friend?

Yes, as a link. It carries the settings only. Your friend opens it, tries it on their own song and chooses whether to keep it.

What does it cost?

Pricing is not set.

When can I get it?

The public launch target is Q2 2027. To ask about the beta, write to info@aurifex.com.

[ Au ] // The gold standard, here

How Nightdrive meets the Aurifex standard

Every Aurifex product must solve a real problem, be proven before it ships, and be effortless to use. Here is what that means for Nightdrive.

Real problem

The edits people want, slowed + reverb, nightcore, 8D, take real audio skills in today’s tools.

Proven

Every build passes an automated end-to-end test gate (63 of 63 checks on the current build) before anyone uses it.

Effortless

Four guided steps, one sentence in Highbeam, or the full studio. Your files never leave your device.
