class Raudio::Wave

• Raudio::Wave
• Reference
• Object

Overview

Wave represents raw audio data Use this for loading and manipulating audio waveforms

Defined in:

raudio/wave.cr

Constructors

• .load(filename : String | Path) : self

  Load wave data from file Supported formats: WAV, OGG, MP3, FLAC, QOA

• .load_from_memory(file_type : String, data : Bytes) : self

  Load wave from memory buffer

Class Method Summary

• .load(filename : String | Path, &)
• .ready?(handle : LibRaudio::Wave) : Bool

  Check if wave data is ready

• .unload_samples(samples : Slice(Float32))

  Unload wave samples data Only call this on samples returned by #load_samples

Instance Method Summary

• #channels : UInt32

  Number of channels

• #close
• #copy : Wave

  Copy wave data

• #crop(init_sample : Int32, final_sample : Int32)

  Crop wave data to specified samples range

• #export(filename : String) : Bool

  Export wave data to file

• #export_as_code(filename : String) : Bool

  Export wave data as code (.h)

• #finalize
• #format(sample_rate : Int32, sample_size : Int32, channels : Int32)

  Convert wave data to desired format

• #frame_count : UInt32

  Frame count

• #load_samples : Slice(Float32)

  Load wave samples as a floats array Returns a Slice of Float32 containing the sample data Note: You must manually call .unload_samples on the returned pointer when done

• #ready? : Bool

  Check if this wave is ready

• #release
• #released? : Bool
• #sample_rate : UInt32

  Sample rate

• #sample_size : UInt32

  Sample size (bit depth)

• #to_unsafe : Raudio::LibRaudio::Wave

  Get the underlying C struct
