好きな曲を着信音に: ファイルをドロップし、ベストな20〜30秒をハンドルで囲み、フェードをオンのままにしてきれいに始まり終わるようにして、ダウンロード。すべてブラウザ内で完結 — 何もアップロードされません。
音声ファイルをここにドロップ、またはクリックして選択
MP3・WAV・AAC/M4A・OGG — ローカルでデコード、アップロードなし
Android: MP3でダウンロードし、Ringtones フォルダに移動(または設定 → サウンド → 着信音 → ストレージから追加で直接選択)。 これで完了 — ほとんどのAndroidはMP3着信音をそのまま受け付けます。 iPhone: Appleは30秒未満のM4R形式しか 受け付けず、ブラウザはM4Rを作れません。確実な無料ルート: ここでWAVをダウンロードし、 iPhoneで無料のGarageBandを開き、空のプロジェクトにクリップをドロップして、共有 → 着信音を選択 — GarageBandが変換してインストールします。切り出す場所は賢く: イントロよりサビ、そしてフックの1拍前から始めると脳が曲を認識する時間ができます。
曲を読み込み、ベストな20〜30秒(たいていサビ)をハンドルで囲み、クリック音が出ないよう「フェード」をオンのままにして、Android用はMP3、iPhoneのGarageBandルート用はWAVでダウンロード。編集はすべてブラウザ内で行われます。
AppleはM4R形式を要求しますが、ブラウザでは作れません。確実な無料ルート: カットをWAVでダウンロードし、iPhoneの無料アプリGarageBandを開き、空のオーディオプロジェクトにクリップをドロップして、共有 → 着信音。GarageBandが変換・インストールし、設定 → サウンドに現れます。カットは30秒未満に — iOSの制限です。
iOSは最大30秒を強制。Androidは何秒でも再生しますが、留守電に切り替わるまで着信が鳴るのはせいぜい25秒です。フックの少し前から始まる20〜30秒が実用上のベスト — 選択が超えるとツールが警告します。
波形の途中から始まるカットは、可聴のクリック音(プチッ)から始まります — 着信音の音量では耳障りです。0.4秒のフェードが端を滑らかにします: クリック音を消すのに十分な長さで、曲がすぐ始まる短さです。
