Overview

Soren is a standalone desktop app for automated audio mastering, with mix analysis and controls for shaping the final output. It suits musicians and producers who want a local mastering workflow without a DAW plugin; it is a weaker fit for album sequencing or batch jobs, which it does not support.

Its mix guidance, reference matching and configurable exports make it more than a one-click mastering option, but the €249 starting price and desktop requirements call for a deliberate fit check.

Key features

The Mix Agent analyzes a mix before mastering and suggests corrections for tonal imbalance and resonances. Ten genre profiles and 27 curated Smart References offer starting points, while users can upload a reference track for analysis of spectral balance, dynamics and tonal qualities. That combination is useful for shaping a master toward a particular sound, though suggestions are not a substitute for deciding whether the mix itself needs revision.

Advanced controls include spectral and stereo processing toggles, custom LUFS targets and safeguards against over-processing. These give users more say over the result than a fixed-output workflow, but also make Soren better suited to people comfortable making mastering decisions than those seeking no-adjustment simplicity.

Exports include WAV at 44.1 or 48 kHz in 16- or 24-bit, MP3 at 320 or 256 kbps, and three True Peak limiting options. Processing happens locally, and Rast Sound says no internet connection is needed after initial online activation. The listed file support reaches 90 minutes on Apple Silicon M1 with 16 GB RAM; that specific configuration matters for longer material.

Pricing

Soren is paid, has no free plan and offers a free trial. Soren costs €249,149, paid once, billed Today's Offer, for a single user with two license activations, commercial use allowed and company use excluded. This is the individual option, but the company-use restriction rules it out for business deployment.

Soren Business costs €399,299, paid once, billed Today's Offer. It includes five license activations, multi-user access for up to three users, commercial use and company use. It is the relevant tier for a small team; its higher cost buys broader use rights and more activations, not a larger stated user allowance than three.

Platforms

The stated desktop requirements are macOS 12 or higher or Windows 10/11, with at least 8 GB RAM recommended. The maker also says Soren is available for iPhone and iPad. Soren is a standalone app rather than a DAW plugin, so buyers should confirm that this workflow fits their setup.

Who it's for

Soren is best for individual creators or small teams who want automated mastering with mix diagnostics, reference analysis and control over loudness and export format. It is not the right choice for users who need batch processing or album sequencing, or who require a plugin-based workflow.

Pros and cons

• Pros: Mix analysis and reference matching can guide corrections and tonal direction before mastering.
• Pros: Local processing, adjustable LUFS targets and multiple WAV and MP3 export settings support a configurable offline workflow after activation.
• Cons: The individual license excludes company use, while the business license is limited to up to three users.
• Cons: No batch processing or album sequencing means extra work for multi-track releases.
• Cons: The stated 90-minute file support applies to Apple Silicon M1 with 16 GB RAM, not every supported desktop configuration.

Verdict

Its local workflow and detailed controls are the case for paying; look elsewhere if you need batch processing, album sequencing, company use on an individual license, or a plugin workflow.
