目前,电脑声卡音频,MP3,MP4(自解码)及CD,SACD,DVD甚至蓝光碟及双模光碟等多媒体音源,多为解压缩数模转换流,通常用晶体管或集成电路音频放大器放音,具有犀利的分析力和强劲的动态,给人以朝气蓬勃、催人奋进的感召力,把铜管乐、打击乐及各种交响乐等演绎得淋漓尽致。但由于音响或音乐作品内容五彩斑斓,乐声又有轻重缓急,纯粹使用或长时间使用晶体管或集成电路放大器,实践表明其表达弦乐人声或特殊音源如数码音源等,感觉音域略显狭窄单调、泛音少;音律转换速率稍快,音质有感直白生硬,缺泛情调
At present, multi-media audio sources such as computer sound card audio, MP3, MP4 (self-decoding), CDs, SACDs, DVDs and even Blu-ray Discs and dual-mode discs are mostly decompressed digital-to- analog conversion streams, usually with transistors or integrated circuit audio amplifiers, With sharp analytical and dynamic, giving a vibrant, inspiring charisma, the brass, percussion and various symphony deduced most vividly. However, due to the colorful musical or musical compositions, the music has its own priorities. The use of transistors or integrated circuit amplifiers for a long time or simply means that the sound field is slightly narrower and monotonous , Less overtone; temperament conversion rate slightly faster, the sound quality is straightforward, lackluster mood
