Description
本発明は、サウンド処理、および、より具体的には、車両用オーディオシステムのデジタルサウンド処理およびオーディオ信号の等化に関する。
車両用のオーディオシステムの設計には、複数の異なったファクタが考慮されている。オーディオシステム設計者は、車両におけるスピーカの位置および数を選択する。各スピーカの所望の周波数応答もまた決定されなければならない。例えば、インストルメントパネル上に配置されるスピーカの所望の周波数応答は、後部ドアパネルの下部分に配置されるスピーカの所望の周波数応答とは異なり得る。
本発明による車両用オーディオシステムのデジタルサウンド処理設計システムは、コンピュータ、および、このコンピュータによって実行される設計ツールを備える。デザインツールは、ユーザが、テンプレートファイルに格納されるサウンド処理基準を定義することを可能にする。オーディオ信号プロセッサは、オーディオソースの第1および第2のリアルチャネル入力に接続される。オーディオ信号プロセッサに結合されるメモリは、テンプレートファイルを格納する。オーディオ信号プロセッサおよびメモリに結合されたサウンド処理エンジンは、テンプレートファイルを実行時に読み出して、サウンド処理基準を取得する。サウンド処理エンジンは、サウンド処理基準を第1および第2のリアルチャネル入力に適用する。設計ツールは、ユーザがバーチャルチャネル入力、および、部分的に第1および第2のリアルチャネル入力に基づく出力を生成することを可能にする。
次の詳細な説明は、好適な例示的実施形態のみを提供し、かつ、本発明の範囲、適用性または構成を制限することは意図されない。むしろ、好適な例示的実施形態の次の詳細な説明は、当業者に、本発明の好適な例示的実施形態を実装を可能にするための説明を提供する。添付の特許請求の範囲に示される本発明の主旨および範囲から逸脱することなく、エレメントの機能および構成において種々の変更がなされ得ることが理解される。
