Adsterra privacyVaporwave takes a track down to roughly two-thirds speed, rolls off the high frequencies, and adds a wide, drifting reverb. The result sounds like music heard from another room in a memory — which is precisely the aesthetic.
The four ingredients:
- Speed around 65% is the genre standard. Slower feels drugged, faster loses the signature drag
- Top-end roll-off removes the crispness that the original relied on. This is not a defect — the softened high end is what makes the style recognisable
- Reverb at around 60% wet turns a slow track into a hazy one
- Chorus drift adds a slight pitch wobble, imitating worn tape
How it differs from slowed + reverb: slowed and reverb keeps more of the original's presence and mostly adds space. Vaporwave deliberately degrades the top end and adds modulation, which is why it sounds older and less defined rather than simply slower.
Try this: a low-pass setting around 8–10 kHz is the sweet spot for most material. Above 12 kHz the effect is barely audible; below 5 kHz the track becomes a muddy wash with no detail.
Rights note: a vaporwave edit is a derivative work. Decoding, processing, and encoding all run in this browser tab. The file you select is not uploaded, and the rendered audio is not stored on any server.
Supported Formats, File Limits & Local Privacy
Formats & Codecs
| Input formats | MP3, WAV, FLAC, OGG, Opus, M4A, AAC, plus MP4 & WebM audio tracks |
|---|---|
| Output formats | Uncompressed 16-bit PCM WAV; MP3 at 128, 192, or 320 kbps |

Size Limits & Privacy
- No server upload cap: files never leave your browser tab, so there is no remote file-size paywall.
- Memory ceiling: decoded audio is held in browser RAM as 32-bit float PCM (~10 MB per minute of 44.1 kHz stereo). Tracks under 30–45 minutes run reliably on standard laptops.
- Zero data retention: closing or refreshing the tab clears every audio buffer from memory immediately.
How This Compares to Cloud Audio Tools
Most browser-based audio utilities (such as 123apps or Clideo) upload your media to remote processing queues. Here is how OfflineTTS differs:
| Criterion | OfflineTTS (Vaporwave Maker) | Typical Cloud Web Editors |
|---|---|---|
| File upload | None — decoded & rendered in your browser tab | Audio file uploaded to remote servers |
| Account / daily cap | No signup, no daily file quota, no watermarks | Often gated by daily file limits or paid tiers |
| Speed on large files | Instant start (no upload wait); bounded by device RAM | Upload + queue wait, then server-side CPU render |
| Works offline | Yes, once the page is loaded | Requires active network round trip |
How It Works
Load a track
Add the song you want to turn into a vaporwave edit.
Slow it down
65% is the standard; adjust between 55% and 80%.
Soften the top end
Roll off above 8–10 kHz and add reverb and chorus.
Render and export
Preview the haze and download WAV or MP3.
Features
Genre Standard 65%
The speed the style is built around, adjustable from 55% to 80%.
Tape-style Roll-off
Removes the top end so the track sounds older than it is.
Reverb Wash
Up to 90% wet for the characteristic hazy depth.
Chorus Drift
Subtle modulation that imitates worn analogue tape.
Slowing, Filtering, and the Aesthetic
Vaporwave's signature is degradation used deliberately. The style grew out of slowed, repitched, and filtered versions of 1980s corporate and lounge music, and the softened, slightly unstable quality of those edits became the point rather than a side effect. That is why the roll-off control here goes as low as 2 kHz: it is a creative parameter, not a defect to be minimised.
The interaction between speed and filtering is what defines the result. At 65% speed with a 9 kHz roll-off, a bright pop track becomes hazy and distant. At the same speed with no filtering, it just sounds slow. If the render does not sound like vaporwave, the filter is usually the parameter that was left at its default.
Extremes, Levels, and Rights
Pushing the speed to 55% while also rolling off aggressively produces something almost unrecognisable, which can be the goal — but it also exposes phase-vocoder artefacts heavily. Drums turn into smeared thuds and consonants lose their definition. That is a legitimate aesthetic choice, but it is worth knowing that it is the algorithm's limit rather than a subtle effect.
Reverb, slowing, and filtering all reduce perceived level while the peak can still rise, so check the processed preview against the original before publishing. If the result sounds quiet, the fix is a small output trim rather than more reverb.
Every effect here is deterministic: the same file and the same control values produce the same output. That means you can reproduce a result later, but it also means the tool will not guess what you intended — check a short excerpt before rendering a long file, and keep the original.

Vaporwave Maker — FAQ
What speed is vaporwave?
Around 65% of the original tempo, which is roughly two-thirds speed. The genre's early releases were often made by simply slowing tracks in a sampler or player without pitch correction, which is why the pitched-down character is part of the sound.
How much should I roll off the top end?
A low-pass around 8–10 kHz suits most material. Below 5 kHz the track loses all definition; above 12 kHz you can barely hear the difference and the effect disappears.
Do I need the chorus?
No, but it helps. The chorus introduces a slow pitch drift that imitates a worn cassette, which is a large part of the aesthetic. At 30% it is subtle; above 60% it becomes an obvious wobble.
What is the difference between vaporwave and slowed + reverb?
Vaporwave is slower, rolls off the high frequencies, and adds modulation. Slowed and reverb keeps the original's tonal balance and mostly adds space. They sound related but distinct.
Can I sell a vaporwave edit of a commercial track?
No, not without a licence. Slowing and filtering a track does not create a new original work for copyright purposes. Personal and classroom use are separate questions from commercial distribution.
