Release notes2026 · 07
Older iTunes libraries, decoded again.
Dkompos 1.6.6 fixes a narrow ISO-MP4 compatibility regression in
1.6.5. Zero-filled metadata padding is now treated as padding—not as
a nested media atom—so affected AAC and M4A files open normally.
Compatibility
Legacy M4A restored
Older iTunes-authored files with padded metadata lists now open and decode normally.
Scope
One bounded fix
Only free and skip padding classification changes; strict atom boundaries remain intact.
Proof
The reported album passes
All 12 affected tracks decode completely with zero wrapper-versus-reference sample mismatches.
A parser edge case, not an AAC failure
- Symphonia 0.6 correctly found the AAC stream but misclassified zero-filled
ilst padding as a metadata container.
- Dkompos now ignores
free and skip atoms in that metadata list, matching their ISO-MP4 purpose.
- Malformed nested atoms still fail closed; the broader size and allocation hardening remains unchanged.
Qualified on the exact affected structure
The release adds an end-to-end padded-M4A regression fixture and
passes the full Rust workspace, release-profile allocation tests,
arm64 bridge and native app builds, Developer ID signing, Apple
notarisation, stapling, Gatekeeper assessment, and checksum
verification.

Release notes2026 · 07
A newer decoder, with the same honest output.
Dkompos 1.6.5 moves its Rust audio stack to Symphonia 0.6 while
preserving the playback contract around it. The migration is backed
by deterministic media fixtures, stricter format policy, richer
library discovery, and explicit resource limits for malformed files.
Audio
Proven fidelity
A deterministic 17-format corpus checks exact decoded samples and bridge parity instead of assuming an upgraded decoder sounds the same.
Library
Better metadata
Typed tags, chapters, Matroska audio discovery, and quieter scan diagnostics carry more useful structure into the library.
Security
Bounded parsing
Untrusted lengths are capped, allocations are fallible, and malformed-media behavior is exercised outside the app process.
Symphonia 0.6 without decoder drift
- FLAC, ALAC, PCM, and MP3 handling use explicit codec and container policy rather than broad accidental acceptance.
- ALAC magic-cookie data is preserved through decoder setup, and MP3 selection follows its canonical codec identifier.
- End-of-stream, truncated-input, and recoverable decode conditions are classified consistently at the application boundary.
- A deterministic corpus across 17 formats verifies exact samples, frame counts, and Rust-to-Swift bridge parity.
More of the file becomes useful library data
- Typed metadata values retain their meaning instead of being flattened prematurely into arbitrary strings.
- RIFF INFO compatibility and ID3 chapter parsing recover common titles, people, dates, and audiobook structure.
- Matroska audio files are included in supported library discovery.
- Repeated scan failures are aggregated into quieter, actionable diagnostics rather than flooding the log.
Malformed media gets a bounded answer
- Length-derived allocations are capped at 64 MiB before memory is requested.
- Fallible reservation maps invalid declarations and allocation failure to explicit errors instead of process aborts.
- Adversarial fixtures run in disposable child processes so a regression cannot take the qualification harness with it.
Signed, notarised, and transparently qualified
The release passed locked Rust compilation, formatting,
warnings-as-errors Clippy, the complete Rust workspace suite,
production bridge regeneration, native application compilation,
Developer ID signing, Apple notarisation, stapling, Gatekeeper
assessment, DMG verification, and checksum verification. The hosted
full-Xcode XCTest job did not execute because of current CI
infrastructure and remains tracked release debt.
Release notes2026 · 07
Exact playback, calm interaction.
Dkompos 1.6.4 makes direct-output replacement an ordered, observable
lifecycle. It also completes the geometry, motion, and accessibility
pass across the whole application without replacing the design you
already know.
Audio
Deterministic routes
Exact-output transitions coordinate, verify, release, and recover in a strict order without weakening the bit-perfect claim.
Motion
Smooth and scoped
Home scrolling no longer competes with shell, carousel, banner, hover, or selection animation.
Interface
One geometry system
Collections, tables, settings, playlists, audiobooks, Now Playing, and DJ surfaces share consistent responsive rules.
A route lifecycle that finishes what it starts
- A new direct route waits until the outgoing lease has finished restoring and the device is quiescent.
- CoreAudio formats are read first, and only mismatched sides are written before bounded convergence.
- Registration, start verification, passive convergence, and one safe restart recovery remain separate phases.
- Progress-aware watchdogs no longer tear down a healthy route merely because one coarse wall clock expired.
Reliable queue advance across format boundaries
- Natural completion and manual Next use the same supervised transition rules.
- Constant-rate changes such as 24-bit to 16-bit at 44.1 kHz no longer expose a restore-versus-coordinate race.
- Processed fallback cannot start while exact device restoration is still in progress.
- The Bit-Perfect badge still requires live non-mixable integer formats, exact native rate, exclusive ownership, and verified callback activity.
The same design, made structurally consistent
- Home, collection, panel, feedback, hover, focus, and selection motion is scoped to the state that owns it.
- Responsive grids, table rows, controls, empty states, and shell columns now derive from shared geometry rules.
- Reduce Motion, text scaling, keyboard focus, VoiceOver labels, cursor feedback, and localisation are applied more consistently.
- Persistent bounded logs retain enough route evidence to diagnose a playback failure after the session ends.
Signed, notarised, and verified
The release passed Rust formatting, locked compilation,
warnings-as-errors Clippy, the complete Rust workspace suite,
production bridge regeneration, native application compilation,
Developer ID signing, Apple notarisation, stapling, Gatekeeper
assessment, and checksum verification. Exact-output queue advance
was also exercised against a physical Chord Mojo 2.
Release notes2026 · 07
Motion that preserves your place.
Dkompos 1.6.3 turns the shell and library into one continuous native
workspace. Drawers allocate real space, warm collection state
survives navigation, and page scrolling stays independent from the
motion around it.
Shell
True sibling columns
The sidebar collapses to an icon rail and the queue opens beside the content at desktop widths, without covering Home.
Library
Continuous navigation
Albums, Artists, and Genres keep their completed results, controls, artwork, and scroll position across route changes.
Motion
Scoped and stable
Panels, tabs, active rows, and artwork atmosphere use focused, reduced-motion-aware transitions that do not restart page layout.
Drawers that behave like desktop columns
- The full sidebar and compact icon rail remain mounted while only their clipped column allocation animates.
- The queue keeps its final internal width during open and close, preventing repeated text, artwork, and list remeasurement.
- Narrow windows retain intentional off-canvas panels; normal desktop layouts never overlay the library.
- Rapid reversals preserve motion continuity, and the queue returns correctly after expanded Now Playing closes.
Collections without the click flash
- Store-owned browse snapshots preserve filters, sorting, readiness, completed results, and scroll anchors.
- Refreshes replace the visible projection only after the new result is complete.
- Clicking the active sidebar destination is a genuine no-op instead of republishing the whole workspace.
- Warm album art, artist portraits, album tracks, genre tracks, and discographies paint immediately on revisit.
- Home shelf width updates are debounced, and carousel corrections no longer compete with vertical scrolling during drawer movement.
- Album detail keeps its warm content visible while current data refreshes.
- Genre Albums and Tracks share one header and viewport, cross-fading while the native track table stays outside SwiftUI animation transactions.
- Queue sections own one vertical layout, preventing current and upcoming tracks from overlapping as playback changes.
The build you validate is the build you opened
Development bundles are now visibly named Dkompos Dev and use a
separate bundle identifier and app path. Release builds retain the
production Dkompos identity, and launch tooling targets the exact
executable instead of a shared process name.
Built and qualified for distribution
The release passed the complete Rust workspace gate, production
bridge regeneration, generated-binding drift verification, native
app compilation, Developer ID signing, Apple notarisation,
stapling, Gatekeeper assessment, and checksum verification.
Release notes2026 · 07
One playback truth, from tap to hardware.
Dkompos 1.6.2 replaces competing playback state with one supervised
lifecycle. Source identity, transport, position, active route, and
fidelity evidence now move together as one coherent snapshot.
Playback
One supervisor
Music and audiobooks share preparation, transport, seek, completion, failure, and recovery mechanics without sharing their queues or history.
Outputs
Automatic transfer
Connecting a DAC or changing the Bluetooth default rebuilds the route and preserves the latest playback intent without an app restart.
Library
Stable under load
Home commits shelves in canonical order, artwork work is bounded and coalesced, and large-library pages retain a controlled window.
A coherent playback lifecycle
- Play, pause, seek, source replacement, completion, stop, failure, and route recovery publish through one managed supervisor.
- Rapid commands use latest-wins semantics, preventing stale play or pause acknowledgements from reversing the visible state.
- Audiobooks use the same reliable runtime while retaining isolated progression, history, and queue context.
- Device and stream handles are rebuilt when hardware changes; removal follows the configured managed-route policy.
- Independent Home sources run concurrently but publish in a fixed order, so slow work cannot make shelves pop, reorder, or suppress one another.
- Component timing and outcomes are observable, while candidate-cache writes happen after the visible snapshot is published.
- Artwork extraction and image decoding are capped at four concurrent operations, with duplicate requests coalesced and result order preserved.
- Large track libraries retain a bounded LRU window without evicting requests that are still in flight.
Deeper analysis without an arbitrary ceiling
Offline semantic analysis no longer stops at a fixed 3 GiB
application limit. It remains cancellable and isolated in a
disposable worker process, so macOS can manage demanding model and
library workloads without putting playback or the main app at risk.
Fidelity remains continuously verified
The coherent runtime snapshot includes the live route and fidelity
evidence. Direct, processed, shared, and bit-perfect transitions are
explicit, and a hardware or runtime change revokes an outdated claim
immediately.
Qualified as a release, not just a build
The candidate passed locked workspace compilation, warnings-as-errors
Clippy, the complete Rust suite, Swift bridge generation, production
app assembly, Developer ID signing, Apple notarisation, stapling, and
Gatekeeper validation.
v1.6.12026 · 07
Bit-perfect, proven route by route.
Dkompos no longer treats “Hi-Res,” exclusive access, or a file extension
as proof. The Bit-Perfect badge appears only after the live playback
contract has been qualified and remains under supervision while the
track is playing.

Source
Exact stereo PCM
Qualifying 16-bit or 24-bit lossless audio, decoded without changing the sample values.
Route
Native and direct
Native source rate, direct non-mixable CoreAudio I/O, a compatible integer container, DSP bypassed, and software gain at unity.
Runtime
Continuously verified
Underruns, callback starvation, route changes, format changes, and runtime failures revoke the claim immediately.
How 1.6.1 handles different qualities
-
Bit-Perfect
16-bit and 24-bit PCM
FLAC, WAV, AIFF, and other qualifying stereo lossless sources.
Native rate, value-preserving integer output, DSP bypassed, unity software gain, and verified direct device ownership.
-
Direct Decode
MP3
Decoded once to canonical 32-bit integer PCM.
Native rate with no DSP, resampling, or software gain; never labelled bit-perfect because the encoded source is lossy.
-
Processed
Managed sources and DSP
AAC, OGG, Opus, Vorbis, unsupported layouts, EQ, ReplayGain, crossfeed, software volume, resampling, or channel adaptation.
Played through the managed floating-point path and labelled as processed or shared.
-
Converted
DSD · DSF · DFF
FIR-decimated to PCM.
No native DSD bitstream claim is made.
-
Dedicated
DJ and audiobooks
Purpose-built processed playback contracts.
Kept outside the transparent music contract and never given a bit-perfect badge.
Hardware evidence, not allow-lists
Device capability is inspected live. The release was validated against
direct integer playback on the FiiO K11 R2R and against the Chord Mojo 2's
capability-selected 32-bit container while preserving exact 16-bit values.
Dkompos also restores device state when the route closes.
The rest of the release
- Unifies Home, All Tracks, Albums, Artists, Genres, Hi-Res, Mixes, playlists, Audiobooks, and Now Playing around one charcoal, content-first system.
- Stabilises Home shelves, listening statistics, Continue Listening, and More like this with deterministic, evidence-based recommendations.
- Makes scrolling consistent and responsive across library surfaces, with stable compact playlist headers and a responsive, album-led Now Playing page.

v1.5.4
2026 · 05
Library-scale search, Hi-Res pagination, and interface control polish.
This build moves global search and Hi-Res browsing onto backend
paginated summaries, keeps literal wildcard searches honest, and
tightens virtualized list refreshes so stale async page loads cannot
disturb a newer view.

- Search now uses backend counts and paginated summaries instead of materialising large libraries in the UI.
- Hi-Res browsing is paginated and searchable without pulling every hi-res track into memory.
- Search treats percent and underscore characters literally, while also matching album artist, genre, and path.
- Virtualized lists ignore stale page loads and stale errors after invalidation.
- Track, queue, playlist, and shelf actions use explicit controls with stronger keyboard and popover behavior.
v1.5.3
2026 · 05

- SQLite connection pooling and blocking I/O isolation keep the interface responsive during heavy scans and imports.
- Folder automation now detects added and removed files, keeps Recently Added current, and avoids stale library rows crashing playback.
- Audiobooks sit outside the music category with chapter progress, resume behaviour, and folder-structure tolerant import rules.
- Music tracks longer than 30 minutes are separated into Mixes so albums, tracks, and audiobooks stay clean.
- Playback highlighting, progressive all-tracks queueing, output-device fallback, and album disc grouping are hardened.
v1.3.0
2026 · 04
Professional audio settings, signal-path clarity, DJ workflow.
Direct and DSP signal-path readouts, ambient mixing behaviour,
ReplayGain and crossfeed controls, DJ triage, crates, set composition,
and an export workflow that lands files where the booth expects them.
