キーファインダー

リミックス、サンプリング、ハーモナイズ、ピッチシフト、または新しいパーツを追加する前に、任意の曲のキーとスケールを検出しましょう。

トラックをアップロードし、次のステップへの明確な調性の切り口を得ましょう。検出したキーをサンプルのマッチング、メロディ作成、ボーカルパーツの準備、ステムの調整、またはアイデアを ACE Studio に持ち込んでボーカル、楽器、深度のあるプロダクションに活用しましょう。

ファイルはプライベートです。すべての分析はブラウザ内でローカルに実行され、音声はアップロードされません。

その他のAI音楽ツールを探索

任意の歌のキーを調べる

ボーカル、サンプル、コード進行、または新しい楽器レイヤーを追加する前に、曲の音楽的中心を知ることが重要です。

ACE Studioのソングキーファインダーは音声を分析してキーとスケールを検出し、プロダクションの意思決定に役立つ実用的な参考値を提供します。ループの確認、リミックスの準備、アカペラをインストに合わせるとき、ハーモニーを作成するとき、または既存のトラックをベースに新しいアレンジを構築するときに活用してください。

キーを知ることで、より意図的に制作に取り組めます。フィットするサンプルを選び、ボーカルをより扱いやすい音域に移し、曲を支えるコード進行を構築し、または無理にならない自然な新しいパーツを作成できます。

ソングキー検出後にできること

トラックに合うサンプルを探す

サンプルは単独では強力なことがありますが、セッションに入れると違和案に感じることがあります。往々にして問題はテクスチャやクオリティではなく、キーにあります。

ソングキーファインダーでループ、メロディ、ボーカルチョップ、フルトラックの調性の中心をプロジェクトに入れる前に確認しましょう。キーを知れば、互換性のあるサンプルを選び、パーツをより注意深く移調し、ミックスの問題になる前に音符の衝突を避けられます。

特に以下のような場合に役立ちます:

  • ボーカルチョップ
  • メロディクループ
  • ギターまたはピアノのサンプル
  • ベースライン
  • フル参考トラック
  • リミックス素材

キーを見つけた後は、ACE Studio でステムの分離、新しいボーカルの作成、または曲の和声的方向に合ったサポート楽器レイヤーの構築を続けられます。

歌曲のキーまたはピッチを変える

元のキーを知れば、ピッチ変更がより音楽的になります。

トラック、ボーカル、またはサンプルを新しいキーに移調して、シンガー、コード進行、リミックス、またはアレンジに合わせましょう。ボーカルをより扱いやすい音域に移したり、ビートに合わせてサンプルを移調したり、同じアイデアの明るいまたは暗いバージョンを試したりできます。

小さなピッチ調整でパーツを自然にまとまりやすくでき、大きな変化はムードを大きく変えることができます。キーの結果は参考点を提供し、サウンドがどこから始まったかを準備で山岡する必要がなくなります。

ボーカル作業には、AIボイスチェンジャー がフレーズや音楽的アイデアを変えずに、異なるボーカルタイプを探索するのに役立ちます。

ボーカルをより良くフィットさせるための準備

ボーカルはキーの問題が最も明らかになる場所です。ラインの緊張感、低さ、薄さ、またはインストからわずかに浮いた印象を受けることがあります。

ボーカルパーツを作成、調整、交換、または再構築する前に、ソングキーファインダーでキーを確認しましょう。アカペラをビートに合わせる場合、検出されたキーはボーカルを移調するか、インストを変更するか、または新しい和声サポートを作成するかを決めるのに役立ちます。

ACE Studio 内では、AIボーカルシンセサイザー を使ってMIDIと歌詞からボーカルを作成し、ピッチ、最後呈滝、タイミング、ボーカルコントロール、デリバリーを精密に調整できます。検出したキーを音楽的ガイドとして、演奏を一音ずつ塑形します。

ハーモニーとバッキングボーカルを作成する

強力なハーモニーはキーを知ることから始まります。

ソングキーを検出した後、リードを塩っませずにサポートするバッキングボーカルを作成できます。さんど、五度、オクターブダブル、問いかけ答え形式のパーツ、またはより幅広いコーラスタイルのレイヤーを構築する際の参考値としてキーとスケールを活用してください。

ACE Studio では、AIボーカルツール を使ってMIDIと歌詞からリードボーカル、ハーモニー、多層構造のボーカルアレンジを作成できます。音符、フレーズング、感情表現はあなたが決め、ACE Studio が曲に合ったボーカルパフォーマンスを塑形する手助けをします。

以下の用途に役立ちます:

  • ポップフック
  • コーラスタイルのバックグラウンドボーカル
  • ダンストップライン
  • デモボーカル
  • レイヤードアドリブ
  • リミックスのボーカルセクション

和声編集のためにステムを分離する

トラックの内部を深く掘り下げたい場合は、まずキーを見つけてから各パーツを分離しましょう。

曲の調性的中心を理解した後、ステムスプリッター でボーカル、ドラム、ベース、楽器を分離してください。セクションの再構築、衝突するパーツの除去、インストゥルメンタルの作成、または元の和声に合わせた新しいレイヤーの作成が容易になります。

例えば、フルソングのキーを検出し、ボーカルを分離してから、その下に新しいインスト編曲を作成することができます。またはベースと和音を分離し、同じ和声的基盤に従った新しいAI楽器パーツを持ちます。

キーが分かれば、曲を塑形しながらも曲とのつながりを保つことができます。

同じキーでAI楽器パーツを作成する

キーを知れば、そのトラックに属する新しい楽器パーツを作成できます。

キーを AI楽器 ワークフローに持ち込んで、MIDIを作成またはインポートして弦楽器、金管楽器、木管楽器などのパーツを塑形しましょう。検出したスケールをガイドに、メロディ、カウンターメロディ、ベースの動き、和声的サポートを導きます。

以下のような場合に役立ちます:

  • コーラスの下に弦楽器を加える
  • ボーカルの周りにカウンターメロディを作る
  • シネマティックなブリッジを作る
  • リミックスに金管楽器や木管楽器の色彩を加える
  • 折りたたみのMIDIスケッチをより表現力の高い演奏に置き換える
  • 曲のアイデンティティを変えずにアンサンブルの幅を広げる

ACE StudioのAI楽器はMIDIベースなので、音楽制作は常にあなたの手にあります。音符、タイミング、アレンジを制御し、アーティキュレーションと表現を精密に調整して演奏を仕上げます。

新しい音楽レイヤーを生成する

キーが明確になれば、最初から曲に合った新しいレイヤーを作成できます。

ソングキーを念頭に置きながら、プロンプトベースのツール(例: レイヤーを追加)を使ってループ、テクスチャー、または音楽的アイデアを生成しましょう。トラックのムードをサポートするレイヤーをリクエストし、アレンジの実際のニーズに合わせて精密に仕上げましょう。

キーはアイデアの着地点を提供し、ACE Studio がそれを実用的な音楽パーツに塑形する手助けをします。

FAQ

歌曲のキーとは?

歌曲のキーとは、トラックの主要な調性的中心です。メロディ、和音、ハーモニーのほとんどが周りに八り絶うルートノートとスケールです。キーを知ることで、曲と協力しながら作業できます。

音楽のスケールとは?

スケールとは、固定の音程パターンに基づいた音符のグループです。長調スケールは明るく解決感があり、短調スケールはより暗く緊張感があります。スケールはキーに含まれる音符とその関係を明らかにします。

ソングキーファインダーはどのように機能するのか?

ソングキーファインダーは音声内の音符と周波数を分析し、最も頻繁に現れるピッチとその関係を調べ、既知のキーとスケールに対応させます。本ツールはEssentia音声分析ライブラリを使用し、ブラウザ内で完全に動作します。

ソングキーファインダーの結果は信頼できますか?

このツールは良い起点を提供します。フルミックス、和声コンテンツが明確なループ、またはインストゥルメンタルトラックで最も実力を発揮します。山のディストーションの強い音声、打楽器主体の素材、こく短いクリップなどは結果が異なる場合があります。信頼度指標を参考にしてください。

アップロードできる音声ファイルの形式は?

MP3、WAV、FLAC、OGG、AAC、M4Aが対応しています。ファイルは50MB未満かつ5秒以上である必要があります。

音声ファイルはアップロードされますか?

いいえ。本ツールはWeb Audio APIとWebAssemblyを使用してブラウザ内で完全に実行されます。ファイルがデバイスを離れることはありません。

ACE Studioで検出したキーを活用できますか?

はい。AIボーカルの作成、楽器用MIDIの作成、ハーモニーの構築、または新しいレイヤーの生成時のガイドとして使用してください。ACE Studioはキーに封じ込められることはありませんが、知ることでより良い制作上の判断ができます。

歌曲のキーをリミックスやプロダクションに活用できますか?

はい。検出されたキーは、サンプルのマッチング、互換性のあるループの選択、ステムの移調、コード進行の作成、オリジナルトラックに合った新しい編曲要素の構築に役立ちます。
