音を分離して区別して知覚される単位あるいは部分に分けることを「聴覚イベント分析」あるいは「聴覚情景分析(ASA)」と称することがある。Albert S. Bregman著「聴覚情景分析−音の知覚組織化」(マサチューセッツ工科大学、1991年、第4刷、2001年、MITプレスペーパーバック第2版)は、聴覚情景分析について広範に説明している。さらに、Bhadkamkarらの米国特許第6,002,776号(1999年12月14日)は、「聴覚情景分析による音の分離に関する先行技術作業」として1976年にさかのぼる文献を述べている。しかし、Bhadkamkarらは聴覚情景分析の実用的使用を勧めず、「聴覚情景分析に含まれる技術は、ヒトの聴覚処理のモデルとしては科学的観点からは興味深いが、基本的進歩がなされるまでは、現在のところ音分離の実際的技術として考えるにはあまりにコンピュータ的に要求が多く専門化しなければならない」と結論付けている。
自動ゲイン制御(AGC)とダイナミックレンジ制御(DRC)の技術は、周知であり、多くの音響信号経路で普及している。概要として、両方の技術は、音響信号のレベルを測定し、測定したレベルの関数であるアマウント(amount)により信号のゲイン変更をする。線形の、すなわち1:1の動的処理システムでは、入力音響は処理されず、出力音響信号が入力音響信号と理想的にマッチする。さらに、入力信号を自動的に測定し、その測定と共に出力信号をコントロールする音響動的処理システムを想定する。入力信号のレベルが6dB上昇し、処理された出力信号が3dBしか上昇しないとすると、出力信号は、入力信号に関して2:1の比率で圧縮されたことになる。
