Realtime audio processing
in your browser for free 🤘

Play like

Name a song. Get its sound.

Pick your instrument, then type a song, an artist or a sound you like. NowDSP sets up the effects for it, with a preset for each part of the song, so you tap Intro, Verse and Chorus as you play.

All in one

One digital processor. Everything in it.

65 effects that would otherwise fill a pedalboard. Tap Original to hear the plain recording, then tap an effect: it switches over while it plays, so you hear exactly what changes.

What every effect does and every slider means: effect reference · glossary · formula reference

Stack them in any order, and drag them around while you play.

Open formulas

The actual processing, right at your fingertips.

Every effect is a few lines of maths you can read. Open one, change it, and hear the difference while you keep playing. Read the reference: the formula language, all 65 effects and every slider.

Multi-device

Every device joins. One workspace.

Share and other devices join with a short code. In the browser they control and watch your workspace. With the app, any input on any device: your phone with the guitar plugged in, the laptop with the mic, the singer's phone running the vocals, the sound sent straight between the apps.

See where the sound goes

The Routing panel shows every device in the workspace, its inputs and outputs, which rig runs where, and how the sound travels: solid on a device, dashed over the network. The wires move with the sound. Tap any block to switch it on or off.

Rigs

Several rigs. One device.

Run several rigs at once, each with its own input and its own effects, mixed together.

Pedals and looper

Stomp on it. Loop it. Play over it.

Switch to Pedals and every effect in your chain becomes a big tile you can hit mid-song. The Looper records in whole bars, so you can build a backing and play on top.

Tools

Everything to shape and keep your sound.

Everything around the effects that makes dialling in a sound quick, and keeps it for next time.

Plug in. Play.

Playing through a computer shouldn't be a project.

Every time you want to plug an instrument into a computer, it turns into a project. NowDSP skips all of it: open the page and you're playing.

Wherever you play

No pedalboard to carry, nothing to install on a borrowed machine. The same processor on your laptop, tablet and phone, and your setup is still there next time.

Eight things for the best sound

• Keep the NowDSP tab open. The sound runs in that tab, so leave it open while you play.
• Allow microphone access. Your browser asks for it: that is how your instrument gets in.
• Avoid Bluetooth. Wireless headphones and speakers add a delay you can hear.
• Use a USB audio interface. It keeps hum and hiss out of your signal.
• Use a guitar cable. Plugged straight in sounds best.
• Use wired headphones or a line out. To hear yourself without a delay.
• Use Chrome, Edge or Safari. They process audio fastest.
• Close other tabs and apps. So NowDSP gets all the processing power.

Native apps

Want it tighter? Go native.

The browser version is free, with every effect: up to four at a time in each rig, an hour every 12 hours. The app also unlocks your browser, with no limits. But a browser can only get so close to your audio hardware. When every millisecond counts, on stage or in the studio, the NowDSP app talks to your hardware directly.

The apps for Android, iPhone and Windows are coming soon. See what the app adds
