Waveform
See the Sound. Shape the Silence.
Experience the new generation of waveforms - intuitively structured, visually distinct, and instantly adjustable. Zoom, scroll, and edit with precision as each sound takes clear, controllable form.
Toolbar
Cut. Swipe. Boom. Done.
Trim, split, fade, move - editing is fast, intuitive, and fun. With instant shortcuts and Smart Toolbar, your ideas keep flowing without missing a beat.
Split
Perfect Split - Every Time
The Split Tool makes editing ultra-fast and endlessly flexible - precision cuts with unlimited undo and redo deliver maximum control. Every edit is non-destructive, so you can experiment freely and never lose a thing.
Preview
Spot It. Hear It. Nail It.
Zoom in on any sound, any time. The Speaker Tool gives you instant solo preview and crystal-clear feedback on what's playing, where, and how loud. It's like a spotlight for your music - giving you instant visualization of sound, position, and volume in one clean view.
Fade
Fade It. Shape It. Smooth It.
Linear fades, S-curves, swoops, swells, exponential & logarithmic curves - pick your vibe. Just choose your shape, drag the handle, and dial in the perfect fade-in or fade-out. Mix, match, and tweak with the built-in Fade Editor - it's fast, flexible, and addictive.
Open Source Multitrack Recording
MARS is an open source project that is dedicated to making professional multitrack recording simple, accessible, and enjoyable. We believe pristine audio quality should be a standard, not a luxury - and available to everyone without prohibitive costs.

Our mission is to deliver a recording system that is stable, nondestructive, efficient, and build for real world productivity. Whether you're a musician, producer, podcaster, or audio enthusiast, we invite you to try MARS and share your experience.

Open Source, with Responsibility

MARS is fully open source: you are free to study, modify, and adapt it to your needs. If you develop enhancements that could benefit others, we welcome contributions for potential inclusion in the official release.

To keep MARS open & actively developed, redistribution is not permitted.

Instead, we encourage you to focus on what matters most - creating, recording, and sharing your work with the world.
