Faust version 2.88.0

Change log

WARNING: to get the source version

• be sure to download the faust-2.88.0.tar.gz file to get a complete source folder (in particular, with all the libraries).
• on macOS, binary files are still to notarise, you may have to use the xattr -rd com.apple.quarantine file command to remove the com.apple.quarantine extended attribute. See the xattr man page for details on how to use that tool. MacOS Monterey is now the minimal version.

New

• cpp vector backend: a read-write table keeps its write and its reads in one loop.
• cpp vector backend: a shared delayed read at a non-simple delay gets a loop of its own.
• cpp vector backend: the loops of a level are emitted by creation rank, not by address.
• cpp vector backend: a recursive read reserves its delay line and defers the write.
• Parallelize ARM64 Docker build.
• Produce a properly code signed .mxo in faust2max6, and stop leaving temporaries.
• tests: heatmap.py names an elected set that is a leg by the leg.
• tests: the generated bodies go outside the source tree by default.
• tests: remeasure.sh times the elected option sets with the bench instrument.
• tests: summary.py reads the legs by header, not by position.
• tests: heatmap.py runs with the python that has matplotlib.
• tests: the bench measures named legs, heat-maps of the efficiency per grid.
• tests: the bench summary reports the efficiency per unit of work.
• tests: a bench round lasts at least 100 ms.
• tests: a bench for the synthetic tests, cpp against ocpp per family.
• tests: synthetic tests, one file of named entry points and a checker.
• emitter: Int32 add, sub and mul wrap through the faust_wrap_* helpers.
• cpp compiler: members stored in topological order, past reads by interval.
• cpp compiler: a further access to a pending line only uses its name.
• emitter: the soundfile pointer is declared initialized.
• emitter: non-finite real constants take their macros.
• emitter: a read at delay 0 is the signal itself.
• emitter: a negation read delayed takes the cache route.
• scheduling: the frequency sorts of the shape classes get a total order.
• -sig --signature : the program's static signature becomes an option.
• scheduling: the shape colour is the shape tree's serial, not its address.
• the branch's environment variables are gone : 67 FAUST_* names, three families.
• loop split: the harvested display tail is emitted on the split path.
• loop split: keep the displays -- no harvest under -ls, widgets in the tail cost.
• help: every shipped scheduling option gets its line.
• genetic: expose the search hyper-parameters and a gene restriction.
• -rp --ring-preload: the ring-preload regime gets its flag.
• fine-grain tail cost: do not walk descriptor branches as signals.
• treeorder sweep completed on master-dev-kept consumers (merge wave A-bis).
• the auto-pilot and the harness (merge wave J).
• the scheduled emitter, whole (merge wave F2+G+H+I).
• the guarded regimes, two gathering completions, and a B+C erratum (merge wave F1).
• the gathering: reveal, kernel normal form, and their ocpp emission (merge wave E).
• the signals library and the fixpoint typing, decoupled together (merge wave B+C).
• the tlib socle, and the determinism gate armed (merge wave A).
• impulse-tests: two witnesses shaped like their bugs (merge wave T).
• Add oteyPiano examples.
• Updated with matched noise and improvements.
• Backends and constant folding: explicit wrapping int semantics.
• Fix WASM build with current Emscripten.
• Make wasmtime embeddable and cut host-call cost on math imports.
• Declare a Faust instrument as an instrument, not an audio effect.
• Rebuild the dynamic CLAP path on a working threading model.
• Rework faust2clap into a working faust2xx tool.
• Document FTZ exponent masks.
• Add NNX backend and migrate JAX backend to Linen (-lang nnx / -lang linen).
• tlib: sync with standalone library (explicit init, local deBruijn2Sym memo).
• tlib: faster version of the Tree library (array-based make, non-virtual Garbageable).
• Introduction of a binary memoization primitive : property2.
• tlib+propagate: lazy per-node properties, fast-path slot, tuple memoization.
• make CTree/Symbol hash tables grow instead of fixed-size.
• faust2daisy improvements & bugs fixed. Support for Patch, PatchSM, hardward PWM, soundfile, and serial communication.

Deprecated

• Remove -fwrapv C++ compiler option since the C/C++ generated code now correctly wraps int32 type.
• Replace the remaining deprecated -Ofast in the tools and impulse tests.
• Replace the deprecated -Ofast by -O3 -ffast-math in faustoptflags.
• Remove the obsolete Max5 tools: faust2msp and faust2w32msp.
• Remove the -diff automatic-differentiation feature.

Fixed bugs

• Destroy the Max/MSP OSCUI when the DSP is reallocated.
• Rebuild the Max/MSP multichannel adapter when the DSP is replaced.
• Serialize GUI registry access in the Max/MSP architecture.
• getErrorAfterException : say nothing when there is no message to say.
• fmod gets its own algebra operation : it is real, % on integers is not.
• Hash in a 64-bit word, not in a size_t : unbreak the wasm build.
• Avoid MSVC option parser nesting limit.
• evaluator: the compile thread gets a 256 MB stack.
• ocpp: refuse -sch cleanly instead of asserting.
• Fix faustbench: main() silently stripped out on recent macOS SDKs.
• Fix faust2clap: support single-dash -help like its sibling tools.
• Fix build against LLVM 23 (devel snapshot) API changes.
• Fade the second half of a stolen voice in, not only the first half out.
• Synchronize faustgen OSC UI lifecycle.
• Fix faustgen polyphony teardown order.
• Include the memory model in the wasm DSP factory cache key.
• Timothy Sikes polyphonic voice stealing order fix.
• Guard Windows code with _WIN32 rather than WIN32 in the compiler.
• Do not return an unwritten buffer from the Windows realpath() shim.
• Report ignored -I / -A directories instead of dropping them silently.
• Fix Faust library path resolution on Windows (#1283).
• poly-dsp.h: Fix division by zero when computing one frame and fading out.
• Correct math hyperbolic functions generation in AssemblyScript backend.
• Fix heap underrun in pathToContent when the file cannot be opened.
• Fix GCC and MSVC builds of the wasmtime runtime.
• Review pass over architecture/clap: leaks, bounds, state and size.
• implement bitcastinst for rust to make -ftz 2 work in rust.
• Set the JIT target before initJIT(), not after.
• Use isPythonBackend() for the negated backend checks too.
• Restore Windows Garbageable cleanup behavior.
• Add Windows faust path diagnostics.
• Fail Windows release on faustgen errors.
• Fix boxCos() and boxFmod() returning the abs primitive (#1264).

Libraries

• rangeOf: affine rules for exact-rational ranges — add/sub a constant, divide by a constant.
• motion.lib: two new pairs of envelopes, motionEnvelopeRange/totalAccelRange (dead-zone given by its two endpoints instead of a threshold plus gain) and motionEnvelopeUD/totalAccelUD (peak follower cascaded with a symmetric smoother, suited to slow gestures).
• Add a windowed-tap transposer and a live granulator to misceffects.lib.
• Add parametric and HRIR binaural rendering to spats.lib.
• Add LMS/NLMS adaptive filters and filter-bank spectral descriptors.
• Add EBU R128 loudness metering and true peak to analyzers.lib.
• Add mid/side encoding and dithered requantization to misceffects.lib.
• Define fi.hilbert, the approximate Hilbert transform.
• Add a window function family to analyzers.lib.
• Add ba.processArray to basics.lib.
• Add interpolators and mel helpers.

Deprecated:

• Mark the remaining music.lib leftovers (de.delay1s..fdelay43s, ba.millisec/time1s..time43s, ef.echo1s..echo43s) as deprecated.

Fixed bugs:

• motion.lib: mo.scale no longer clips the caller's dead-zone above 0.99, which silently rewrote a narrow dead-zone into one ten times too wide with no diagnostic.
• Repair boundFactor, which disabled the tube table interpolation in tubes.lib.
• Fix wa.highshelf2, which carried the lowshelf coefficient formulas verbatim and boosted the wrong band.
• Repair mm.atodb in maxmsp.lib.
