CEDAR Cambridge

CEDAR Cambridge is a modular 64-bit system for speech enhancement and high-resolution audio restoration, built for work ranging from forensic audio to broadcast and mastering. It suits teams and specialists who need configurable processing, automation and track-level reporting. Its breadth is compelling, but the hardware-led configuration and custom pricing make it a considered purchase rather than a straightforward software download.

Overview

Cambridge combines restoration and speech tools in a system that can be configured around the work. Modules can be automated, and the system can process audio at up to 100 times real time, depending on hardware. That speed and automation can matter for large collections or repeatable workflows, but actual throughput depends on the chosen setup.

It can integrate with media asset management systems, adding track reports and associated metadata to a user’s database. For workflows where processed audio must remain traceable, the Report Generator can create a record for every track in PDF, HTML or XML. PDF reports include graphic-handling and page-numbering improvements made in response to ISO/IEC 17025 requirements; that is a targeted reporting feature, not a claim of general certification.

Key features

Speech cleanup is a core strength. DNS, DNS Two, FNR and VoicEX target noise in contaminated audio, while NR and Auto Dehiss are designed to reduce noise alongside artefacts, dullness and compression. Forensic options add impulse-noise reduction, adaptive filters and Trinity Enhance tools intended to suppress background noise and improve speech intelligibility.

Cambridge also covers spectral editing and broader restoration. Retouch lets users identify and manipulate individual sounds; dynamics, loudness and EQ modules include normalisation, compression, expansion, limiting and equalisation. Click and crackle removal, hum removal, declipping and batch processing extend its reach beyond speech work. Source separation can identify and separate sources in a live stream or recording, but it requires a suitable microphone array.

The system’s hardware choices shape who it fits. Silent 1 is a compact, silent host for an individual user; Series V is intended for batch processing in archives, libraries and forensic laboratories. Series V can support multiple users with the optional Server Pack and XML Extension. Audio I/O can use an internal RME card for digital I/O, an Apogee desktop interface for analogue I/O, or both together.

Pricing

CEDAR Cambridge is paid, with pricing from £349 and a 14-day trial. The Cambridge system itself has custom pricing: it is a modular hardware-and-software system whose options and configuration vary, and prospective buyers are directed to contact CEDAR Audio for a quote. The entry figure does not establish the cost of a complete system or a particular configuration.

There is no free plan. Buyers should clarify the hardware, modules and any optional Series V components needed for their workload before comparing total cost. The trial provides a limited evaluation window of 14 days; the available pricing terms do not state renewal conditions or seat limits.

Platforms

Cambridge supports macOS and Windows. Its standalone workflow and dedicated host options make it a system-level choice rather than a plug-in-only restoration purchase.

Who it's for

Cambridge is best suited to audio-forensics and security specialists, archives and libraries, broadcasters, and mastering professionals who need more than a single-purpose cleanup tool. Its automated processing, batch capability and per-track reports are especially relevant when work must be repeated or documented. Individual users can look to Silent 1, while organisations handling larger batch workloads can consider Series V; multi-user use on Series V requires the optional Server Pack and XML Extension.

It is less suited to someone seeking a low-cost, simple app for occasional repairs. The modular system and hardware configuration require more purchasing decisions, and the system price is custom rather than a fixed checkout price. CEDAR offers support through an account-based support team, and its Cambridge v12 announcement described training on host systems, processing modes, batch processing and modules.

Pros and cons

• Pros: Broad speech, forensic, spectral and restoration tools make one configurable system relevant across several demanding audio workflows.
• Pros: Automation, batch processing and reports for every processed track support repeatable, documented work.
• Pros: Series V can serve multiple users with the optional Server Pack and XML Extension, and both listed audio I/O options can be installed together.
• Cons: Custom system pricing and variable configurations make it harder to establish the full cost before speaking with sales.
• Cons: The 14-day trial is brief for evaluating a complex system, and there is no free plan.
• Cons: Source separation depends on a suitable microphone array, so it is not a self-contained option for every recording setup.

Alternatives

For a wider comparison, start with Audio Restoration Software or AI Audio Restoration Software.

• VinylRest is a free option on Linux, macOS and the web; its public-beta Live plan requires a license for processing and allows up to three active Mac installations.
• Neiro is a free alternative available on Linux, macOS, Windows, web and self-hosted setups.
• Cathar is a free Linux and macOS alternative, with no free trial.
• Wave Arts Master Restoration Suite 6 costs $99, paid once for five restoration plug-ins and suits buyers who want plug-ins, provided they have a compatible audio plug-in host.
• SpectraLayers Pro is a paid macOS and Windows option focused on spectral editing, audio repair and restoration, with AI-assisted processing.
• LANDR ReHance is a paid macOS, web and Windows option at $11.99 a month on annual billing; it requires a LANDR Studio subscription.
• Acoustica is a paid macOS and Windows option with Standard and Premium editions for different channel counts.
• Diamond Cut Audio Restoration Tools 11.09 is a Windows-only alternative at $59, paid once, with one year of free support.

Verdict

Choose CEDAR Cambridge if you need configurable speech and restoration processing paired with automation, batch workflows and detailed track reports. Its main advantage is the range of specialised tools within one system; its main drawback is the custom-priced hardware configuration, which demands a larger buying decision than a fixed-price app. For occasional cleanup or a tighter budget, a free alternative or a focused plug-in suite is a more proportionate place to start.
