v1.10.1 — Polish

Polish

• Prevent screen lock during playback — isIdleTimerDisabled now stays on while playing, not just recording
• Red delete buttons — mixer trash button uses .tint(.red) for clear destructive intent
• Record button haptic fix — trigger on tap count instead of state boolean, fires reliably every press

v1.10.0 — Low-Latency Engine

Low-Latency Engine + Concurrency Hardening

Performance

• 5ms hardware IO buffer (setPreferredIOBufferDuration)
• 256-frame tap buffers for tighter loop boundary detection
• Accelerate DSP: vDSP_measqv (RMS), vDSP_maxmgv (peaks), vectorized vDSP_vsmul + vvtanhf (tape warmth)
• Pre-allocated double-buffered metering — zero heap allocation on real-time audio thread
• Coalescing dispatch prevents unbounded meter queue growth under load

Concurrency Hardening

• OSAllocatedUnfairLock for all cross-thread shared state (meter levels, tape warmth flag)
• TaskGroup for bounded concurrent waveform loading
• Task { @MainActor [weak self] } replacing DispatchQueue.main.async throughout
• Proper [weak self] on all AdManager delegate callbacks
• PurchaseManager transaction listener handles nil-self gracefully
• Synchronous silence prefill to prevent file corruption race

Other

• Bluetooth latency warning resets each session (was permanent dismiss)
• Test target deployment aligned to iOS 17.0
• 100 unit tests passing

v1.9.0

What's Changed

• Analog-style VU meter tweening + playback metering by @thorbjxrn in #18
• Ballistic smoothing + fade-on-stop for live waveform by @thorbjxrn in #19
• HIG 8pt spacing grid polish by @thorbjxrn in #20

Full Changelog: v1.8.0...v1.9.0

v1.7.3

What's New

• Screen stays awake during recording — the display no longer goes black mid-session; auto-lock resumes when recording stops
• New default theme — blue-toned theme replaces the previous default
• Natural waveform rendering — smoother, more organic waveform display

App Store

• Headline overlays and card framing for screenshots

v1.7.2 — Ad optimization & library fix

What's New

• Medium rectangle ad on export — replaced 50pt banner with 300x250 MREC for higher revenue
• Combined waveform preview — single time-aligned waveform for M4A/WAV export preview
• Premium stems gate — inline upsell when selecting Stems format

Bug Fixes

• Library delete when ads blocked — fixed inability to delete more than one project when VPN blocks AdMob
• Stable ad row IDs — list no longer thrashes on project deletion
• Ad retry cooldown — 60s cooldown prevents shimmer→fail cycling; session-level failure skips network calls entirely

Removed

• Interstitial ads after export (replaced by MREC revenue)
• Tape gap toggle on export (always included when enabled in settings)

Technical

• Removed dead interstitial loading code (wasted memory/bandwidth)
• Time-aligned combined waveform (layers of different lengths now display correctly)
• Session-level native ad failure tracking to minimize unnecessary network requests

v1.7.1 — Record from current playback position

What's New

• Record from current playback position — hit record mid-playback and the new layer starts at the playhead, not from the beginning
• Loop-mode offset fix — backing layers now play from the correct position when overdubbing mid-loop
• Gap countdown stability — fixed timer stuck at 0 and stale deferred-recording state

Bug Fixes

• Fix loop-mode backing layers ignoring playback offset
• Fix pendingOverdubOnGapEnd not cleared on stop
• Fix gap countdown timer stuck at 0 with self-clearing pattern
• Guard against double-start in startRecording()

Tests

• 19 new GapCountdownTests covering timer/state machine edge cases
• OverdubOffsetTests for silence-padding alignment
• SilencePaddingTests for buffer correctness

v1.5 — Immersive Themes

What's New

• Immersive themes — Porta, Synth, and Sampler themes now go beyond accent colors with full background, surface, and control styling
• Realistic VU meters — Hardware-inspired VU meters for the Portastudio theme with stereo, summed, and waveform modes (tap to cycle)
• Deeper light modes — Porta and Synth light modes have richer, more distinctive palettes
• Themed views everywhere — Settings, Mixer, Library, Export, and Paywall all respect the active theme
• App Store screenshot previews — Debug gallery for capturing pixel-perfect screenshots

Fixes

• Fixed NaN crash from empty audio buffers during route changes
• Fixed Form icon tinting not responding to theme accent color
• Fixed OnboardingView missing environment objects in fullScreenCover
• Unified Porta waveform color with the orange accent family
• Replaced Task churn with DispatchQueue.main.async for audio level updates
• Tracked Xcode shared schemes for reproducible builds
