The OpenMPT/libopenmpt project released the latest stable libopenmpt version:

libopenmpt 0.5.5 (2021-01-31)

  • [New] Makefile CONFIG=emscripten now supports EMSCRIPTEN_TARGET=audioworkletprocessor which builds an ES6 module in a single file with reduced dependencies suitable to be used in an AudioWorkletProcessor.

  • [Bug] stb_vorbis: Fix decoding of Vorbis streams without comments which affected most Vorbis samples since stb_vorbis v1.20.

  • openmpt::ext::interactive::set_pitch_factor wasn’t applied to OPL voices.
  • OPL channel state (in particular current patch) is now updated when seeking.
  • The FT2 tremolo quirk is now also applied to MOD files. FT2 just copied the quirky code from ProTracker!
  • DMF: Preserve effects better in some situations where there is more than one effect in a pattern cell.

  • DMF: Improve import of finetune effect with parameters larger than +/-15.

  • mpg123: Update to v1.26.4 (2020-12-24).
  • pugixml: Update to v1.11.4 (2020-12-22).
