Accessible Tuner is a simple multi-tuner app created by LUCA, a blind developer, who has had some difficulties finding a VoiceOver-accessible tuner app in the past herself. It will start listening for any sounds when the START button is pressed, and will show the closest note, and wheather the note is too high, too low, or in tune. Since the result area changes live, I recommend stopping the function before checking it with VoiceOver. While the Beep sound toggle is turned on, a short beep will be played when the note comes in tune. Keeping this toggle off is recommended bwhen earphones are unconnected, ecause the microphone may pick up the sound. For your information, notes falling within a 10-cent range are determined as in tune. -------- Accessible Tunerは全盲の開発者、LUCAが自らウクレレやカリンバをチューニングする際にVoiceOverで使いやすいチューナーアプリがなく困った経験を元に、乏しいSwiftの知識でなんとか形にした、視覚障害者向けのマルチ・チューナーです。 「START」ボタンを押すと聞き取りが開始され、聴取された音に最も近い音階(A~G)と、それが高いか、低いか、丁度合っているかを表示します。聞き取り中はリアルタイムで結果が変わってしまうため、落ち着いてVoiceOverに読み上げさせたい場合には、音を鳴らした後に一度「STOP」を選択して、結果表示部をご確認ください。 「ビープ音」をオンにすると、丁度になった時に短い音が鳴ります。ただし、イヤホンを使わない場合はビープ音をマイクが拾ってしまうことがあるため、通常はオフがおすすめです。 なお、本アプリでは+-10セント以内を「ちょうど」と判定します。
