class TinySoundFont::SoundFont

• TinySoundFont::SoundFont
• Reference
• Object

Overview

High-level wrapper around LibTSF::TSF Note: Thread safety depends on the underlying C library.

Defined in:

tiny_sound_font/sound_font.cr

Constructors

• .from_memory(data : Bytes, sample_rate : Int32 = 44100, output_mode : LibTSF::OutputMode = LibTSF::OutputMode::StereoInterleaved, gain_db : Float32 = 0.0_f32) : self

  Load from memory buffer

• .new(filename : String, sample_rate : Int32 = 44100, output_mode : LibTSF::OutputMode = LibTSF::OutputMode::StereoInterleaved, gain_db : Float32 = 0.0_f32)

Class Method Summary

• .open(filename : String, sample_rate : Int32 = 44100, output_mode : LibTSF::OutputMode = LibTSF::OutputMode::StereoInterleaved, gain_db : Float32 = 0.0_f32, &)

  RAII helper that ensures close is called

Instance Method Summary

• #active_voices : Int32
• #bank_note_off(bank : Int32, program : Int32, key : Int32) : Int32
• #bank_note_on(bank : Int32, program : Int32, key : Int32, velocity : Float32 = 1.0_f32) : Int32

  Notes using bank/program

• #channel(index : Int32) : Channel

  Channel access

• #close
• #closed? : Bool
• #finalize

  Rescue-only finalizer to avoid leaking native handle

• #handle : LibTSF::TSF
• #max_voices=(n : Int32)
• #note_off(preset_index : Int32, key : Int32)
• #note_off_all
• #note_on(preset_index : Int32, key : Int32, velocity : Float32 = 1.0_f32) : Int32

  Notes using preset index

• #preset_count : Int32

  Presets

• #preset_index(bank : Int32, program : Int32) : Int32
• #preset_name(index : Int32) : String
• #render_float(samples : Int32, mixing : Bool = false) : Slice(Float32)
• #render_float!(buffer : Slice(Float32), samples : Int32, mixing : Bool = false)
• #render_short(samples : Int32, mixing : Bool = false) : Slice(Int16)
• #render_short!(buffer : Slice(Int16), samples : Int32, mixing : Bool = false)

  Rendering API samples is the number of frames per channel

• #reset

  Global controls

• #sample_rate : Int32
• #set_output(mode : LibTSF::OutputMode, sample_rate : Int32 = @sample_rate, gain_db : Float32 = 0.0_f32)

  Configure output again if needed

• #volume=(v : Float32)
