WhitePrint AudioEngine is a web-based AI mastering platform for music producers, audio engineers, labels, and businesses building mastering workflows. It analyzes WAV and FLAC audio with BS.1770-4 loudness metrics, true-peak, LRA, spectral, and stereo measurements. Three AI models deliberate mastering parameters, while section-based processing applies different decisions across detected song sections. Users can provide files or cloud URLs, compare before-and-after metrics, and download mastered WAV files.

Pricing is structured around usage and workflow control. The Free plan costs $0 per month and includes 3 WAV masters per month, analysis, multi-LLM deliberation, section-based mastering, A/B comparison, and a metrics dashboard. Standard costs $67 per month or $648 per year billed annually, adding 30 WAV masters per month, custom LUFS and True Peak targets, 90-day analysis history, and email support. Pro costs $1,365 per month or $13,104 per year and adds unlimited masters, custom DSP parameter overrides, batch processing for up to 10 tracks, a priority queue, unlimited analysis history, and priority support. A 14-day free trial is also listed.

The strongest fit is for teams that need both mastering depth and programmatic access. The API plan costs $2,745 per month or $26,352 per year and includes REST API access, webhooks, 1,000 API calls per month, unlimited batch processing, custom LLM model selection, and dedicated support with an SLA. White Label costs $6,883 per month and adds a custom brand UI, custom domain support, unlimited API calls, dedicated infrastructure, custom DSP chain configuration, and 24/7 dedicated support. Google Drive, Dropbox, OneDrive, Amazon S3, and Google Cloud Storage support broaden file intake. Producers seeking occasional mastering may prefer the Free plan, while businesses needing API routes, automation, or branded delivery are the clearest candidates for paid tiers.
