Module: SFML::SoundRecorder

Defined in:
lib/sfml/audio/sound_recorder.rb

Overview

Static helpers for audio capture. Use SFML::SoundBufferRecorder to actually record; these tell you what hardware is available.

SFML::SoundRecorder.available?           #=> true / false
SFML::SoundRecorder.devices              #=> ["alsa_input.pci-...", ...]
SFML::SoundRecorder.default_device       #=> "alsa_input.pci-..."
