日本の救急車のサイレンアプリ「PiPO」です。 ※※※必ずお読み下さい※※※ 日本特殊車両サイレンアプリ 救急車サイレンの姉妹アプリです。類似アプリにつき、ご購入の際は、間違えないようご注意下さい。 サイレンアンプ機能は付いておりません。よって、手動や周波数が下がっていき消音する機能は搭載しておりません。 録音したサイレンや音声を再生しているだけで、サイレンアンプの機能を再現しているものではありません。 また、「弱」ボタンのハーモニックは、端末によっては一部の周波数の音が表現できない場合があります。 姉妹アプリ「日本特殊車両サイレンアプリ 救急車サイレン」との違い ・ボタンや音声ボタンのデザインが違います ・サイレンの音質が若干違います ・左右折の注意音声の最初に「救急車が」がつきません ・自動のサイレンが付いています (ピーポーと自動サイレンは同時に鳴らすことはできません) ・ボタンタップ時、ピッと音が鳴ります(音は消せません) 収録音 ・ピーポー(約1分) ・自動サイレン(約1分) ・救急車の音声3種類(1ch-3ch) 録音機能 4chに好きな音声を録音できます。 録音した音声は、繰り返し再生できます。 警光燈機能 画面の上下が、ランダムフォーに似たパターンで点滅します。 【音声録音方法】 音声合成ボタンをタップし、右下の数字を4にします。 数字が4の時、音声CHボタンをロングタップすると録音確認メッセージが表示されるので、OKをタップすると録音を開始します。 録音のを止めるには、停止ボタンをタップします。
