A bounce rendered the whole mix (or bus) into memory and then encoded a
second copy, and the render silently stopped at 2^29 samples: about 93
minutes of stereo at 48 kHz, 31 of 5.1, 15 of 7.1.4. Longer bounces came
out cut short while file.bounce_mix still reported the requested length.
- audio-io: FileEncoder writes WAV/BWF (RF64 above 4 GiB), AIFF and FLAC
block by block into any Write + Seek, byte for byte what encode writes
for the whole buffer. check_room fails up front when an AIFF (4 GiB) or
a FLAC (2^36 frames) can't hold the bounce. AIFF and FLAC encode run on
the same writers; their output is unchanged.
- mix: RangeRender renders the main mix or one bus over a range of any
length, a block at a time; render_range and render_bus (in memory,
still capped) are built on it.
- engine: io::Bounce streams the main mix or a bus, or its stereo
fold-down, into "<name>.part" next to the target, syncs it and renames
it into place, so a failed bounce leaves no partial file and keeps the
old one. In the browser it encodes into memory (failing instead of
aborting when memory runs out) and delivers the file as before.
Normalize renders twice (peak, then the scaled write); levels are
measured as blocks are written. Stems stream the same way and share the
4-hour limit.
A 100-minute bounce of the demo session now writes all 288,000,000
frames with 83 MB peak memory.
* Progress docs to the craftrules standard; full re-measure against Pro Tools 2026.4.1
Stage: alpha. Menu breadth 482/512 (94.1%, measured), feature breadth ~70%,
ready for real work ~40%; ~350-570 agent-hours to beta, ~950-1,450 to full parity,
calibrated on this repo's PR history.
- ROADMAP.md rewritten: stage banner, two numbers, dimension/feature/language tables
- docs/target-app-parity.md: authoritative assessment (area table moved from ROADMAP)
- docs/gaps.md: 22 ranked gaps with evidence and estimates
- docs/roadmap.md: milestones, current focus, beta plan
- docs/ui-, file-format-, hardware-, plugin-, localization-parity.md: new checklists
- docs/parity.md -> docs/parity-checklist.md (generated by cargo xtask parity)
- architecture.md: video, vst3-host, au-host crates; device I/O limits

* Stage: pre-alpha under the core-workflow gate
Add the alpha gate to docs/roadmap.md: interface recording at a chosen buffer
size, MIDI recording, and session interchange with Pro Tools fail, so the stage
moves from alpha to pre-alpha (~5 points and ~110-180 agent-hours to alpha).
Mark the alpha blockers in docs/gaps.md; update ROADMAP.md, target-app-parity.md
and README.

* Add mainstream-practitioner and essentials-user readiness numbers
Mainstream practitioner ~36% (weekly-area depth 50.6% x 0.90 interaction x 0.92
stability x 0.85 file exchange) and essentials user ~57% (core-feature depth
72.4% x 0.90 launch/stability x 0.90 discoverability x 0.97 files), with written
weights, discounts and GitHub user evidence. Full ready-for-real-work checked
against its written dimension weights (40.6%); unchanged at ~40%, stage unchanged.

* Readiness by audience: hours to ~95% for full, mainstream and essentials
Full ~40% / 950-1,450 h, mainstream ~36% / 380-600 h, essentials ~57% / 110-200 h,
calibrated on this repo's PR history. The full number is already an additive
weighted sum over the written dimension table; method unchanged.

The desktop app installed no logger, so every log::warn!/log::error! in
the workspace was discarded: the engine's panic report, audio devices
that failed to open or broke, plugins that refused their stored state or
failed to activate, CLAP plugins' own log messages, files that failed to
open. A launch from a desktop menu has no terminal either, so there was
nothing to attach to a bug report.
apps/soundcraft/src/logging.rs (no new dependency):
- standard error plus <settings dir>/logs/soundcraft.log (beside
ui.json, Autosave/ and Presets/); each launch rotates the previous log
to soundcraft.1.log and .2.log, so the log of a run that crashed
survives the next start; the file is capped at 16 MiB
- records logged before the settings directory is known are buffered
(bounded) and written once the file is attached
- default levels: info for soundcraft*, warn for everything else;
RUST_LOG replaces them with env_logger-style directives
- never panics: an unusable directory or a failed write leaves standard
error as the only sink; a poisoned lock is tolerated
- runs with SOUNDCRAFT_NO_PREFS (agents' test runs) log to standard
error only, so they don't rotate away the user's own logs
Realtime audio: a record takes a lock and does I/O, which the audio
callback must never do, yet code on the audio thread logs (the cpal
error callbacks, the synth's full event queue, a hosted plugin's failed
process, a CLAP plugin calling the host's log, the panic hook). The cpal
callbacks now mark their thread (soundcraft_mix::mark_audio_thread,
re-exported by soundcraft_playback), and the mix engine carries the mark
into the rayon workers that render strips for it. A record from a marked
thread is not written there: the first is kept in a fixed buffer
(try_lock, no allocation, never waits), the rest are counted, and the UI
thread writes them every frame (any other thread before its own next
record).
The logger is installed first in main (before the engine's panic hook)
and the file is opened after argument parsing (--version leaves no
file). The settings directory moves out of prefs_path into config_dir.
The control server's eprintln!s go through the logger (the
SOUNDCRAFT_CONTROL_PORT line on standard output stays). Documented in
README.md (Getting started > Logs) and docs/architecture.md (Audio).
