Audio conversion & upsampling
High-quality conversion across PCM and DSD workflows, with explicit sample-rate and bit-depth targets, CD-ready conversion and high-resolution resampling / upsampling profiles.
CDR Audio Master is being built for controlled professional audio workflows — from high-quality PCM and DSD conversion to Audio CD authoring, verification and the next generation of delivery and archival tools.
CDR Audio Master is designed as a professional desktop workflow for preparing, converting, checking and delivering audio. The public release is not available yet; the status labels below distinguish what is already present in internal builds from what is still being developed or planned.
High-quality conversion across PCM and DSD workflows, with explicit sample-rate and bit-depth targets, CD-ready conversion and high-resolution resampling / upsampling profiles.
Prepare Audio CD projects, control track order and authoring details, run write simulation and burn using the connected optical-drive workflow.
Measure output audio and document the processing path with technical evidence, including level checks and verification reporting for completed workflows.
Work with DSD material and SACD ISO files already supplied by the user, alongside the PCM conversion and verification pipeline.
DDP tooling is being developed against real-world sets, including structure inspection, PQ parsing, CD-TEXT interpretation and validation.
Planned tools will extend the workflow to large collections, archival masters and multiple delivery targets while keeping processing rules consistent and reviewable.
Format support is being expanded deliberately. “Current build” means present in internal development builds — it does not mean the application is publicly available yet. Planned items may change before release.
* DFF support is subject to the final release decoder matrix and validation scope.
DDP inspection and validation are being refined against real-world test sets.

These areas are planned, not shipping claims. They describe the intended direction of the product after the core conversion, verification and authoring foundation is stable.
Create and preserve archival masters with the source, metadata and verification record kept together as a controlled workflow.
Queue albums and larger collections, apply consistent conversion and verification rules, and review results without processing each file manually.
Build multiple output targets from the same approved source workflow — for example CD, high-resolution PCM, archival and other delivery masters.
CDR Audio Master is in active development and validation on macOS. The final release feature set, supported format matrix, system requirements and commercial availability will be published when the product is ready for public release.
The application interface shown here is an illustrative preview. Features marked Planned are roadmap items and may evolve before implementation.
