Web13 jun. 2024 · 因此，基於PCM編碼的WAV被作爲了一種中介的格式，常常使用在其他編碼的相互轉換之中，例如MP3轉換成WMA。 簡單來說：pcm是無損wav文件中音頻數據的一種編碼方式，但wav還可以用其它方式編碼。 網上很多資料都是移除wav文件的頭部44個字節後，獲取的就是pcm。 WebWe automatically scale the data from int16->float32 upon reading it in xarray (if decode_cf=True). There's no way to turn that off and still get automatic scaling, so the best you can do is layer on int16->float32->float64, when you might prefer to only do int16->float64.
