class Raudio::AudioStream

• Raudio::AudioStream
• Reference
• Object

Overview

AudioStream represents a custom audio stream Use this for procedural audio or custom audio processing

Defined in:

raudio/audio_stream.cr

Constant Summary

NOOP_CALLBACK = ->(buffer : Pointer(Void), frames : UInt32) do end

NOOP callback retained to avoid GC (used when clearing callbacks)

Constructors

• .load(sample_rate : UInt32, sample_size : UInt32, channels : UInt32) : self

  Load audio stream (to stream raw audio pcm data)
