Creative reverb from real places
Capture a space. Take its sound with you.
One clap. A stairwell, a tunnel, a tiled bathroom, caught in sound. Spaceprint turns the character of a place into a reverb you can hear, see and keep. Watch its sculpture take shape, hear instruments inside it, then export a WAV impulse response for your music.
- Capture with one clap
- See and hear its character
- Standard WAV export

What it is
Every room has a sound. Now you can keep it.
Clap in a stairwell and listen: the sound rings, bounces and fades in a way that belongs to that place alone. An impulse response is a recording of exactly that, and a convolution reverb uses it to put any other sound in the same place.
Spaceprint captures that character with your iPhone. Make one sharp clap and let the space ring out. Hear a snare, voice, piano or synth through the result, collect it with a photo and a note, and take it into your DAW as a WAV impulse response. The little imperfections are part of the sound: this is a creative reverb tool, made for finding places you want to hear again.

Capture
A moment in a room. A sound you can keep.
One sharp clap starts it. Spaceprint listens while the room answers.
-
01 / Listen
Clap once. Let it ring.
Start the capture, wait for the countdown, then make one sharp clap. Keep the phone still and stay quiet. Spaceprint listens for the tail to fade, while an acoustic bloom follows the sound.
-
02 / Discover
See what you heard.
The recording becomes a reverb sculpture you can turn with a finger. Its shape responds to the sound and builds again as you audition it. An impression of the room’s voice, rather than a model of its walls.
How it works
Five steps from a place to a print
Find a space
Anywhere with a sound of its own: a stairwell, a church, a tunnel, a tiled bathroom, a parking garage.
Place the phone
Put it where you’d like to hear the room from, then take a couple of steps away.
Clap once
Start the capture, wait for the countdown and clap sharply. Stay quiet and still while the space rings out.
Listen
Hear a snare, voice, piano or synth through the space, or replay the original clap. Compare Dry and Wet to hear the difference.
Keep it
Name the space, add a photo or note, and export its impulse response as a WAV for a compatible convolution reverb.
Features
Everything it does
Built for collecting character and putting it to use in music.
One-clap capture
A countdown, one sharp clap, then the room ringing out. Spaceprint automatically listens for the tail to fade.
Acoustic bloom
A living visual follows the capture as the room rings out, then gives way to the finished reverb sculpture.
A sense of character
Plain descriptions and an estimated decay help you recognise the sound. Long, bright, dense: keep the spaces that speak to you.
Hear the space
Audition snare, voice, piano and synth, or replay the captured clap. Compare Dry and Wet, then adjust Mix and Pre-delay.
Decay
How long the space rings, estimated for every capture and shown at a glance.
Helpful capture advice
If the clap is clipped, too quiet or obscured by noise, Spaceprint explains what to try for a better take.
Reverb sculptures
Turn a shape made from the captured sound. Watch it build again as you listen. Its form expresses the reverb, not the geometry of the room.
A collection of places
Save and name each space, add a photo, and write down where you were and what you heard. Reopen it whenever a track needs that character.
WAV export
An ordinary WAV impulse response, through the share sheet and the Files app, never locked into an app.
Clean recording
Captures use the microphone in measurement mode, without voice processing or automatic gain.
iPhone and iPad
Made for the phone in your pocket, so any room you walk into can be captured.
Private by design
No account, no tracking, no ads. Your spaces stay on your device.
Screens
Every space has a shape of its own.

One click opens a pairing QR. Transfers stay on your local network. Your spaces live in a shared desktop library, and the selected impulse response is saved with the DAW project.
About the Windows preview
Windows 11 x64 tested, with a 64-bit VST3 host such as REAPER. Windows 10 execution and other hosts remain unverified. This is an unsigned preview build; Windows ARM is not verified.
Long impulse responses at 96 kHz with very small buffers can cause audio dropouts. REAPER offline-render repeatability and end-to-end physical iPhone transfer checks remain open. Try a larger audio buffer and verify rendered audio before relying on this preview in a project.
Windows guide
From download
to your first space.
01Install the Windows VST3
- Close your DAW, download the ZIP and extract it.
- Copy the entire Spaceprint.vst3 folder into
%LOCALAPPDATA%\Programs\Common\VST3\. Create that directory if needed. Keep the folder'sContentssubfolder and all its files together. - Reopen your DAW and scan for VST3 plug-ins. Add Spaceprint as an effect on an audio track or return channel.
To update, close the DAW and replace the existing complete Spaceprint.vst3 folder. The download is a plug-in bundle, not an installer or a standalone application.
02Find it in REAPER
Use 64-bit REAPER. Open Options → Preferences → Plug-ins → VST. If the user VST3 folder is not already scanned, add %LOCALAPPDATA%\Programs\Common\VST3 to the plug-in paths using its expanded folder path, then choose Re-scan.
Open a track's FX browser and search for Spaceprint. Midnight Studio is loaded by default; the space selector includes all five Factory Spaces and your own library. Play the track to hear the reverb and see the live spectrogram.
03Send a saved space from iOS
- Connect your iPhone or iPad and Windows computer to the same local network. The computer can use Ethernet while the phone uses Wi-Fi.
- In the VST, click Transfer from Spaceprint iOS. A QR code appears immediately.
- In the iOS app, open a saved space and tap Send to Desktop. Scan the QR, choose your captures and tap Send selected captures.
- The received spaces appear in the desktop library. The latest transfer loads automatically by default.
Send to Desktop requires the iOS full-version unlock. The iOS app's App Store availability is listed above. You can use Import IR with an existing WAV without the phone app.
Allow Camera and Local Network access for Spaceprint on iOS. If a connection fails, check that both devices are on the same private network and that the DAW is allowed through Windows Firewall on that network. Avoid guest Wi-Fi that isolates devices. Transfer settings → Network connection lets you select the correct adapter; create a new QR after changing it.
04Start with the sound
On a track insert, start with a modest Mix and adjust it while listening. On a dedicated reverb return, set Mix to 100% and control the amount with the send. Use Pre-delay to separate the dry attack from the reverb, and Length to shorten a long tail.
Low Cut and High Cut affect the reverb only. Ducking lowers the tail while the dry signal is present; Wet Level controls the reverb level before the blend. The blue and amber layers use the same level scale so you can see how these changes affect the audible result.
05Checksums, updates and feedback
Release 0.1.0-preview.1 · source revision 7d83e60. The download checksum lets you compare your ZIP with the published file. The archive also contains an installation guide and checksums for its contents.
This preview is unsigned, so Windows may identify an unknown publisher. Obtain it from this official page and follow your system's security guidance. Please report your DAW version, sample rate, audio buffer size and the steps that caused a problem to contact@nightlybuildaudio.com.

Spaceprint guide
A little guidance.
Then make it yours.
Find a place with a voice, then take a little of it home. These instructions follow the current development build.
01Capture your first space
Set the phone where you want to hear the room from and step back about two paces. Choose Capture a Space, then Start Capture. After the countdown, cup your hands slightly and make one sharp, loud clap.
Keep the phone still and stay quiet while the room rings. Spaceprint listens for the tail to fade and then prepares the result. Wait for a quiet moment before starting: voices, traffic and ventilation become part of the recording.
02Explore the reverb sculpture
Drag the finished sculpture to turn it. Its shape comes from the recorded sound; it is an impression of the reverb, not a scan of the room. The character words and estimated decay describe what you captured.
Play a test sound to see the sculpture build again as you hear it. Choose a capture for its musical character and use any capture advice to decide whether to try another take.
03Audition and compare
Under Play Test, choose Snare, Voice, Piano or Synth to hear it through the captured space. Clap replays the original capture. Tap the active sound again to stop it.
Switch between Dry and Wet. In Wet mode, Mix controls how much reverb you hear, and Pre-delay changes when it arrives. These are listening controls; the exported WAV is the impulse response itself.
04Save a place, photo and notes
Save the capture and give it a memorable name. Reopen it in My Spaces, then open its details to add a photo, place name or notes about the sound. Photos are optional; the sculpture can stand in for one.
The place is text you enter yourself. Photos and notes stay with the library entry and are not included in the exported WAV.
05Export an impulse response
Choose Export Space on the captured or saved space. It comes with the full version: Spaceprint is free to try, and one purchase, never a subscription, unlocks exporting and keeping as many spaces as you like. Use the share sheet to save the WAV to Files or send it to your music-making setup. Load it into a convolution reverb that accepts WAV impulse responses.
The file carries the captured acoustic character. Apply it to drums, instruments or voices in your reverb plug-in and set the blend there.
06Change the look or improve a take
Settings offers Midnight, Ember, Dusk, Aurora and Spectrum colour schemes. The current build also lets you explore Ripples, Nebula, Orb, Ridges and Terrain sculpture styles. These visual choices change how the sound is drawn, not the captured audio.
If a clap clips, move farther from the phone. If it is too quiet, move a little closer and cup your hands. For a noisy capture, wait for a quieter moment and let the whole tail finish before moving.
