(1)DAT与CD都采用16bit的PCM技术,但各自采用不同的取样频率。DAT为48kHz,而CD则为44.1kHz,对CD来说它不能直接进行数字——数字录音,原因是选择了不同的取样频率。 (2)音质上DAT磁带与CD唱片相同。DAT有明显的优点,即消费者可以自己进行录音。但目前已出现一种可录音的CD唱片格式。 (3)DAT放音时间长。一盒标准数字音频磁带最长放音时间为2小时,CD唱片最长放音时间约为1小时。 (4)预录磁带方面,与CD相比,DAT优点是适用于小汽车,DAT磁带包装较CD唱片小且比CD唱片容易
(1) DAT and CD all adopt 16bit PCM technology, but each adopt different sampling frequency. The DAT is 48kHz, while the CD is 44.1kHz, which can not be directly digital-to-digital for CDs because of the different sampling frequencies chosen. (2) Sound quality DAT tape and CD record the same. DAT has the obvious advantage that consumers can make their own recordings. But now there is a recordable CD record format. (3) DAT playback time is long. A box of standard digital audio tape playback time up to 2 hours, CD record playback time is about 1 hour. (4) Compared with the CD, the advantage of DAT is that it is suitable for a car in the pre-recorded tape. The DAT tape package is smaller than a CD record and is easier than a CD record
