DROffline is a cost-effective software designed to complement the DRMeter real-time dynamic range estimator plug-in. It provides essential file-based metering options including official DRi Dynamic Range, SPPM Peak, and RMS amplitude measurements. Users can analyze single audio files or perform batch measurements on entire directories, making it suitable for evaluating albums or large collections of tracks efficiently in the background.

This application faithfully recreates the classic TT DR Offline Meter for use on modern macOS and Windows systems, catering to audio engineers and enthusiasts focused on dynamic range quality. DROffline offers two primary modes for assessing dynamic range, enabling detailed analysis of individual tracks or bulk processing of directories. It fills a key gap for professionals concerned with maintaining dynamic range integrity throughout the production process.

Dynamic Range (DR) has become a widely accepted standard since 2009 for measuring the amount of compression applied to popular music. DROffline generates an official integrated DRi value to quantify this compression. Audio engineers commonly use DROffline alongside the DRMeter plug-in to monitor dynamic density in real time during mixing and mastering, ensuring that audio maintains its intended dynamic characteristics.
