什麼叫音質?
補充:
重點如引,這先定義出來,不然只怕許多人的定義都有所不同,討論就更形差異.(漸漸有人意識到有些討論在定義上的重要性了,呵.)
如WIKI也會有"音質"之篇文,裡面也會談到客觀評價與主觀評價,及其評價法,樓主所欲言的音質是否與WIKI所言的一樣呢?(無人能知),因此這事兒若起頭不一,後面也可想而知.

音質(おんしつ、英: sound quality)とは音や声の品質を表し、多くの場合電子機器などのオーディオ出力や音声出力の良し悪しの意味で用いられる。品質の内容はアプリケーションにより異なり、高音質のオーディオ機器では聴感上の原音への近さが、電話では明瞭度や了解度が重要になる。
音質は、人間が実際に音を聞いて判断する主観評価や、音の何らかの性質を測定して決める客観評価で定量化することができる。 音の物理的特性だけではなく人間の聴覚システムの特性が音質に大きな影響を与えるため、主観評価が音質評価の基本になるが、多くの評価者や専用の評価設備が必要で時間・コスト共に掛かり環境や評価者による評価のばらつきがあるため、音の物理的特性から主観評価値を推定する様々な客観品質評価法が研究されている。

Sound quality is typically an assessment of the accuracy, enjoyability, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to the sound or gauge its perceived similarity to another sound.
The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, processing and mastering done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it. In some cases, processing such as equalization, dynamic range compression or stereo processing may be applied to a recording to create audio that is significantly different from the original but may be perceived as more agreeable to a listener. In other cases, the goal may be to reproduce audio as closely as possible to the original.
When applied to specific electronic devices, such as loudspeakers, microphones, amplifiers or headphones sound quality usually refers to accuracy, with higher quality devices providing higher accuracy reproduction. When applied to processing steps such as mastering recordings, absolute accuracy may be secondary to artistic or aesthetic concerns. In still other situations, such as recording a live musical performance, audio quality may refer to proper placement of microphones around a room to optimally use room acoustics.
