v3.2.0

What's Changed

• PolyBLEP oscillators rewritten in C++ for improved performance
• Bugfix in sampleseq event timing
• Updated event emitter in web and offline renderer for improved type interface
• Decorated the Renderer and web-renderer with a promise-based API
• Added setCurrentTime API for web and offline renderer
• Add el.sampleseq2 node: similar to sampleseq but with pitch shifting and time stretching behavior

New Contributors

• @johncalvinroberts made their first contribution in #36

Full Changelog: https://github.com/elemaudio/elementary/compare/@elemaudio/core@3.1.0...@elemaudio/core@3.2.0

v3.1.0

Feature

• New el.sampleseq node for sequencing sample playback (similar to el.sparseq2)
• New el.round node to complete the trio with el.floor and el.ceil
• New el.skcompress soft-knee compressor (#34 by @Mozoloa)
• Runtime::snapshot method for capturing the internal graph state

Improvement

• Added a CMake namespace alias so that linking against the runtime subdirectory can be written elem::runtime

Bugfix

• Fixed a bug in el.compress which had inverted the behavior of the ratio parameter (#34 by @Mozoloa)

v3.0.0

Breaking

• Virtual File System no longer supports overwriting entries
• Composite nodes are no longer supported

Feature

• Refs and core.createRef
• el.sparseq2 for value sequencing as a function of time
• el.mm1p and el.prewarp, a multimode TPT one-pole filter from "The Art of VA Filter Design" and a corresponding cutoff prewarp utility
• el.sphasor, an explicit version of el.phasor for accepting a sync signal

Improvement

• No longer compiling with wasm-exceptions enabled (better cross-platform/cross-browser support)
• Drop dependency on mpark::variant
• Add ElemNode type def to the core library
• Drop the optional sync signal from el.phasor (hence the explicit el.sphasor) which gives an explicit API and slight performance win

Bugfix

• Add more headroom to el.capture to prevent dropouts in recording

v2.1.0

Deprecating

• Deprecate virtualFileSystem overwrite behavior
  • v3 will remove this behavior, ensuring immutable access to the shared resources
• Deprecate composite nodes
  • v3 will remove composite nodes to support refs and proper memoization

Feature

• Remove 8 child limit
• Add types to event emitter events @bgins
• Update virtual file system to support listing known paths and pruning unused entries
• Update bleptriangle coefficients for better discontinuity prevention @pauliusuza
• Add capture node for recording signals with sample-accurate timing

Performance

• Improve wasm event batch processing and web-worker communication overhead using transferables

Bugfix

• Fix tap promotion, no more buzzing from feedback taps in new graph structures
• Fix event propagation from idle graph nodes
• Fix loading the web-renderer virtualFileSystem from the worklet processorOptions

v2.0.1

Minor

• Refactor cli tool to more easily enable devs to make custom builds (#11)
• Remove composite node memoization, fixing a long standing bug
• Fix cli documentation

v2.0.0

Breaking

• Dropped support for the plugin-renderer and node-renderer package
• Convolve, Metro, Time, and FFT nodes now only available by default in the WASM (web-renderer, offline-renderer) packages
• Table, Convolve, Sample, and any other nodes which depend on static audio buffers now only respond to a path property which resolves against the virtual file system
• TapOut no longer accepts a size property; all tapOut nodes have an implicit block-size delay

Features

• Open source, opening up the Runtime API for custom native integrations and extended audio processors
• Introducing a new svf and svfshelf node
• The internal implementation of the lowpass, highpass, bandpass, lowshelf, highshelf, peak, and notch filters now use the above svf nodes
• New generic Renderer API in @elemaudio/core for writing custom rendering utilities

Minor

• Significant CPU and memory usage improvements
• Significant performance improvement on the frontend reconciliation algorithm
