Class EventBufferQuery

Namespace

NAudio.Sequencing

Assembly

NAudio.Core.dll

Stateless per-buffer event query — the dispatch math used by SequencedSampleProvider<T>, exposed as a standalone API for consumers that don't want to route events through a MixingSampleProvider (e.g. a VST3 instrument provider feeding events into a plugin's process() event input).

Remarks

Stateless by design: the caller supplies an arbitrary [startFrame, endFrameExclusive) range, so a host that pulls e.g. 4096 frames from WASAPI can split the work across multiple downstream process() calls if the plugin's max block size is smaller. The dispatcher receives each event with its effective absolute tick (after the position transform and, in a loop, after iteration translation) and a sample-accurate frame offset relative to startFrame. Queries are audio-thread friendly: they run over the timeline's lock-free immutable snapshot (see EventsInRangeSpan(long, long)) and perform no heap allocations.

Methods

Query<T>(EventTimeline<T>, ITempoMap, IPositionTransform, LoopRegion?, long, long, int, Action<SequencerEvent<T>, int>)

Invokes dispatcher once per event whose effective fire-frame lands inside [startFrame, endFrameExclusive).
