ART Coach is a planning workspace for Dirac Live Active Room Treatment (ART) calibration. Describe your system once, and a seven-step wizard turns it into a structured plan: speaker groups, support relationships, per-group starting values, and a target curve that matches how you listen. ART Coach does not measure your room and does not replace the correction process. It organizes the decisions that come before measurement, then exports everything for review and manual entry. WHAT YOU CAN DO (FREE) • Define your speaker layout, channel counts, and low-frequency limits • Derive speaker groups and support relationships automatically • Choose a Sound Strategy that fits your room and subwoofer layout • Set a listening intent for movies or music, chosen from 13 presets • Review Fsiso, support levels, and bandwidth for every group • Check room background noise before you measure; audio is analyzed in real time, never recorded or stored • Export a Setup Sheet and Detailed Reference (TXT, PDF, or clipboard), plus a Target Curve file ART COACH PRO (ONE-TIME UNLOCK, NOT A SUBSCRIPTION) • Save every configuration in the ART Library • Shape bass with Pro Bass Shaping and the Target Curve Editor • Organize repeat calibrations with folders and templates • Sync your library across devices with iCloud • Review version history and compare configurations side by side • Add notes and custom group names; import and export configurations • Use Home Screen and Lock Screen widgets, Spotlight Search, and Siri Shortcuts ART Coach is a planning and education tool. Its outputs are structured starting points, not final acoustic results. Final settings depend on your room, speakers, equipment capability, placement, listening level, and your measurements. Always validate settings against equipment limits and safe listening practices. ART Coach is an independent application and is not affiliated with, endorsed by, or sponsored by Dirac Research AB.

Apply that same file to L/R, Center, surrounds, heights, and the Primary LFE group when present; each group follows only the range inside its measured correction curtains. - Choose one of four purpose-built profiles: Movie Reference Level, Movie Everyday Volume, Music Reference Level, or Music Everyday Volume. - Intent, Emphasis, Curve Shape, and Pro Bass Shaping refine the bass region without creating different curves by speaker role. Sound Strategy remains separate and controls how ART groups cooperate. - Keep Speaker Voicing preserves your established full-range speaker targets and exports one bass-only curve through 160 Hz for the Primary LFE group or identified bass destination. - New configurations start with House Curve and Everyday Volume. Configurations saved before v1.0.5 retain their bass-only behavior until you intentionally change the target approach. - Screen 6 now presents the approach, profile, control points, and application guidance in one clear vertical flow. Screen 7 exports one directly importable target-curve file for the selected approach. - Systems without subwoofers now receive explicit guidance for the actual main-speaker bass destination and its measured usable range. - Individual grouping now preserves each speaker's calculation role, so front, center, surround, and height speakers keep the intended support policy when split into separate groups. - Cross-subwoofer support stays within each target group's usable range. When you load a saved configuration, ART Coach now rebuilds group assignments, Fsiso, and support recommendations from the saved inputs instead of relying on cached calculated values. - Onboarding, the Guide, setup sheets, and technical references now explain both approaches, Movie and Music voicing, correction curtains, and the simplified export workflow. PDF pagination and long-name wrapping are also improved. ### v1.0.4 — 2026-08-02 This update improves recommendation consistency, applies speaker and nearfield subwoofer limits more reliably, and makes infra-bass decisions using the complete channel group. Older saved configurations refresh with the latest calculation rules. • Nearfield subwoofer limits and the speaker capabilities you enter are now applied more consistently, including when using Custom Emphasis. • Support recommendations stay within the capabilities you provide. When a group has no usable support range, ART Coach now explains why instead of showing a misleading value. • Infra-bass target points now consider the complete channel group, so a limited speaker or subwoofer does not make the whole group appear infra-bass capable. • Older saved configurations refresh using the latest calculation rules while preserving custom group names and preferences. • Parameter review checklist changes now save automatically. ### v1.0.3 — 2026-07-27 This update makes guidance clearer and improves reliability throughout ART Coach. • Strategy and intent labels now identify only constraints found in the system you entered. Expanded cards explain that no label means no known limit, not a recommendation, and show both when to choose an option and when to consider another. • Strategy tradeoffs now appear in text and PDF exports. Switching between Movie and Music also asks before discarding a preset or emphasis. • Corrected nearfield and combined-sub calculations. Older saved configurations refresh from their original inputs when loaded. • Improved the reliability of saved and shared configurations, widgets, Siri Shortcuts, Spotlight, and version history. • Fixed Pro purchase and restore handling when App Store confirmation arrives after the purchase sheet closes, with clearer messages for pending, cancelled, and not-yet-confirmed purchases. • Improved VoiceOver, Dynamic Type, and accessibility descriptions across strategy, intent, grouping, chart, and tool controls. • Fixed additional export, file-handling, room-noise, microphone-calibration, and audio-analysis edge cases. ### v1.0.2 — 2026-07-25 This update improves iCloud sync reliability and display consistency. • Fixed an issue where Pro's first iCloud sync on a new setup could fail before any configurations were saved. • Group summaries now always show F-support values you can enter directly: a speaker rated between entry steps (for example 51 Hz) previously showed its raw rating in the group summary while the entry rows showed the next step up. • The target curve chart caption now uses the same one-decimal precision as the curve values table. ### v1.0.1 — 2026-07-17 This update refines the recommended support settings to draw even more from your speakers and subs. * Subwoofer support now starts at the subwoofer's own usable low-frequency floor instead of where the assisted group leaves off, so supported height and bed channels can draw on your subs' full depth. * Support Level recommendations are now tailored to speaker position, placement, and strategy, replacing maximum-contribution defaults. * Your chosen strategy is reflected in the levels again, not just the ranges, and choosing an Emphasis refines the recommendation without shifting those levels. * The primary LFE group's own row now covers its full recommended range at the appropriate contribution. * Recommended frequencies no longer round below a speaker's rated extension. * Combined subwoofer groups now receive the same recommendation regardless of the order the subs were added, and mixed placements keep the most protective frequency limits. * Setup sheets are clearer about omissions: - Unlisted supporter relationships should stay unchecked. - An intentionally omitted within-group row now says so. * Clearer labels distinguish the primary LFE group from the timing-only LFE Reference setting. * The LFE Reference recommendation now matches the calibration software's own selection rule. * Fixed Professional PDF layout issues where the LFE guidance block or the Setup Notes list could split across pages. * Fixed an issue where marking a speaker as reviewed was not saved until another edit was made. * Improved VoiceOver on the Parameters step: each supporter row now reads as one complete relationship. If you entered values from an earlier version, we recommend generating a fresh setup sheet and re-entering the updated recommendations. Your speakers, groups, and preferences are unaffected. ## Related topics [artcoach](https://appshunter.io/ios/topics/artcoach) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
