Abstract
【解決手段】パラメータ変換器106は、マルチチャンネルのスピーカの構成に関するマルチチャンネル音声信号の第1および第2音声信号のエネルギー関係を示しているレベル・パラメータを生成する。レベル・パラメータは、ダウンミックス・チャンネルに関連する複数の音声オブジェクトのためのオブジェクト・パラメータに基づいて生成される。それは、音声オブジェクトに関連するオブジェクト音声信号を使用して生成される。オブジェクト・パラメータは、オブジェクト音声信号のエネルギーを示しているエネルギー・パラメータを含む。コヒーレンスおよびレベル・パラメータを導き出すために、パラメータ・ジェネレータが、使用される。そして、エネルギー・パラメータとオブジェクト・レンダリング・パラメータとを合成し、所望のレンダリングの構成に依存する。

そのような、ユーザは、
−(カラオケ・タイプのアプリケーション)を協力するためのある機器を抑制し/減らす。
−それらの選択(例えば、ダンス・パーティに対するドラム音が大きく、弦楽器音が小さいか、リラクセーション音楽に対するドラム音が小さく、ボーカルが大きい)を反映するために元のミックスを修正する。
−それらの選択にしたがって、異なるボーカル・トラック(弾性のリード・ボーカルを介した女性のリード・ボーカル)の間で選択する。
