Changelog

All notable user-facing changes to DSPark are documented here.

[1.7.0] - 2026-08-21

Added

  • OnsetDetector, BeatTracker and LoopFinder for transient analysis, tempo/phase tracking and bounded crossfade-ready loop discovery.
  • LoudnessNormalizer for offline LUFS normalization under a true-peak ceiling.
  • TimeStretch, PitchCorrector and SpectralFreeze for phase-vocoder time, pitch and spectral processing. Spectral freeze retains captured magnitudes while phases advance, are reconstructed or are decorrelated according to the selected mode.
  • FlacFile for dependency-free native FLAC decoding, MidiFile for Standard MIDI File reading and writing, and KeyDetector for major/minor key estimation.
  • Public Biquad::setCoeffsNow() for coefficients computed by the stream owner and for single-threaded or offline processing.
  • Deterministic installed-header, include-order, dependent-comparison, concurrent-suite and float-cast-overflow sanitizer checks.

Changed

  • Automatic analysis windows now preserve their time span across sample rates. Resolved sizes are exposed through the relevant size getters, including PitchDetector::getWindowSize().
  • Audio-thread staged-state adoption is bounded. A contended update may be deferred to a later processing call instead of making the callback wait for the control thread.
  • BiquadCoeffs is a non-template, double-precision coefficient set, and the Biquad recursion remains in double precision for both float and double buffers.
  • AudioBufferView converting and pointer-array constructors express const-correctness as constraints, so type traits and requires expressions now report the legal conversion direction.
  • AudioProcessor now describes a genuinely in-place processor. Read-only analysers no longer satisfy the concept.
  • CI treats supported compiler warnings as errors and runs AddressSanitizer, UndefinedBehaviorSanitizer and float-cast-overflow coverage with GCC and Clang.

Fixed

  • Hardened WAV, MP3, FLAC and MIDI parsing against malformed sizes, truncated data and invalid metadata without adding runtime codec dependencies.
  • Preserved valid processor state when prepare() receives non-finite or non-positive sample rates, including PitchCorrector.
  • Left AudioBuffer safely empty after an allocation failure instead of retaining dangling channel views.
  • Hardened plugin and DSParkLab host-input, shared-state and editor-lifetime boundaries while preserving real-time processing contracts.
  • Removed shared fixed temporary filenames from the I/O test suite so parallel test processes remain isolated.

Migration

Source and latency changes are covered in the v1.7.0 migration guide.

[1.6.1]

  • Added the AlgorithmicReverb Eco quality mode.
  • Added impulse-response decay scaling and tape-speed-style stretching to ConvolutionReverb.
  • Added matching DSParkLab controls for the new reverb options.
