WaveMachine Labs ReStem Pro

A Stem Separator Exclusively for Drums

Meet ReStem (formerly ReBeat), an AI-powered stem separator designed exclusively for drum tracks.

Unlike generic stem separation tools, ReStem focuses solely on your drum mix.

Whether you're working with live recordings, electronic beats, or full mixes, ReStem delivers precision by separating your drum tracks into six distinct stems: kick, snare, hi-hat, toms, ride, and crash.

Built on decades of drum recording expertise and trained with thousands of hours of in-house drum performances, ReStem gives you the clarity and control you need to perfect your drum sound.

From mixing and editing to creative experimentation, ReStem is the ultimate tool for anyone serious about drums.

ReStem is intentionally designed as a non-realtime stem separator, prioritizing quality over speed.

While real-time separation tools may offer instant results, they sacrifice precision and clarity to achieve that speed.

ReStem takes a different approach by processing your tracks after playback to ensure the highest level of accuracy and detail.

Custom-Trained AI Model

At the heart of ReStem is a custom-trained AI model, purpose-built for drum separation. General-purpose stem separators attempt to handle everything from vocals to guitars, but ReStem’s AI focuses exclusively on drums.

Using thousands of hours of meticulously recorded in-house drum performances, we trained the model to recognize the unique characteristics of each drum element - kick, snare, hi-hat, toms, ride, and crash.

ReStem doesn't just excel with isolated drum tracks, it also performs remarkably well on tracks that contain drums along with other instruments.

Even in dense mixes, the AI can pinpoint and separate drum elements, ensuring clean professional-grade stems that sound natural and ready for mixing.

Whether you're isolating a snare from a live recording, separating cymbals in a full mix, or eliminating bleed from other instruments, ReStem delivers results that generic tools simply can't match.

Built-in Effects

The Pro version of ReStem goes beyond separation by offering a suite of built-in processing tools designed to give you even more control over your drum stems.

Drumagog

Included within ReStem is the industry-leading Drumagog drum replacer, allowing you to replace or augment your kick and snare stems with high-quality samples.

Choose from the comprehensive Drumagog sample library or load your own samples for endless creative possibilities.  

Look-Ahead Noise Gate

Tighten up your drum stems and remove unwanted bleed with ReStem's powerful noise gate.

The look-ahead functionality ensures seamless gating, even with fast transients, making it ideal for both live and electronic drum tracks.  

Transient Shaper

Sculpt the dynamics of your drums with precision.

Boost the attack for a punchier sound, reduce sustain to tighten up resonance, or fine-tune both to fit your mix perfectly.

Local Processing

ReStem is designed with speed, privacy, and reliability in mind, which is why all processing happens locally on your computer.

Unlike many stem separation tools that rely on cloud-based servers, ReStem performs every step of the separation and processing directly on your machine.

This means no extra fees, no waiting for uploads or downloads, no interruptions due to internet connectivity, and complete control over your workflow.

Local processing also ensures your audio files remain private.

Whether you're working with sensitive client material or personal projects, your tracks never leave your computer, giving you peace of mind and full ownership of your work.
