NAudio.Midi 3.0.2-preview.2

NAudio.Midi

Nuget

MIDI support for NAudio. Dual-targets net9.0 (cross-platform: the MIDI event model and file reader/writer) and net9.0-windows10.0.19041.0 (adds WinRT live MIDI I/O on Windows).

What's included

  • MidiFile for reading Standard MIDI Files (SMF)
  • MidiEventCollection and MidiEvent hierarchy (NoteEvent, NoteOnEvent, ControlChangeEvent, PatchChangeEvent, TempoEvent, TimeSignatureEvent, MetaEvent, SysexEvent, …)
  • MidiFileWriter helpers to produce MIDI files from a MidiEventCollection
  • Enumerations for General MIDI patches, drum notes, controller numbers, etc.
  • Windows only: WinRTMidiIn / WinRTMidiOut — live MIDI input and output backed by the WinRT Windows.Devices.Midi API (present only in the net9.0-windows build; the cross-platform net9.0 build omits them)

What's not here

Sending or receiving live MIDI through the legacy winmm-backed MidiIn / MidiOut uses the Windows Multimedia API and lives in the NAudio.WinMM package. (The WinRT-backed WinRTMidiIn / WinRTMidiOut above are the modern alternative and ship here.)

See the NAudio documentation site for tutorials and the full API reference, or the GitHub repository for full documentation and tutorials on working with MIDI files and events.

  • Fixed Mp3FileReaderBase seeking silently restarting playback from the beginning of the file on MP3s with a Xing/Info header — the lazy frame index was gated on IsLengthExact, which such a header sets without any frame having been scanned. Also fixed seeks landing on the wrong frame when the target fell exactly on a frame boundary, and Xing/Info header frames being indexed as audio (shifting every seek in those files ~26 ms early). A 3.0.0 regression (#1419)
  • Fixed WdlResamplingSampleProvider losing samples, and eventually returning 0 permanently, when asked for more output than the source could supply — a 3.0.0 regression that broke the common pattern of reading generously from a BufferedWaveProvider-backed capture chain. WdlResampler.ResampleOut also no longer drifts in input-driven (feed) mode when handed fewer samples than ResamplePrepare requested (#1412)
