[#1] 真的可將youtube convert to wav? Download youtube to wav的軟件真的有用嗎?youtube 上載時質量,上載後還可以再解成wav file?不是應該怎樣都不會超出原上載時的質量嗎?有勞各位師兄指教 |

[#2] 真的可將youtube convert to wav? 會唔會wav的意思只是一個檔案格式,不代表他的解像度質量,一個MP3質量的歌都可以製成wav檔案,跟聲音質素沒有關係。 你都可以把一個CD質素解像度的檔案放入dsd檔,只不過重播出來的效果就只有CD的解像度⋯⋯ |

[#3] 真的可將youtube convert to wav? wav file 大很多,如果不能提升質量,那有什麼必要去轉wav,那這種軟件亦沒有存在價值了 |

[#4] 真的可將youtube convert to wav? 其實有好多野製造出來都冇乜價值,哈哈。 我冇用你講嗰個軟件,但係或者佢有內置oveesampling 技術,用換算程式嘗試「extrapolate」一些本來失去的資訊也不奇⋯⋯我只係亂咁估 |

[#5] 真的可將youtube convert to wav? 如果上載時已經遺失的訊息還可以尋回就真係幾神奇,點解總係覺得好多似是而非的事物根本在欺騙我們,我們是不是被玩了? |

[#6] 真的可將youtube convert to wav? 多去了解便好了 電腦確實是有能力做到無中生有的,但能力有多高?大家自己衡量好了 |

[#7] 真的可將youtube convert to wav? Oversampling是可以把本來失去的訊號「猜回」,這就是oversampling的作用,絕對唔係咩新鮮野。佢用一些數學algarithm去「估、算、猜」出來,不會是真的跟原來一模一樣,但未必個個人聽得到分別。 最後修改時間: 2019-06-08 15:35:08 |

[#8] 真的可將youtube convert to wav? Oversampling and upsampling are not exactly the same... With oversampling, extra copies of the same sample are added to the original one. With upsampling, the levels of extra copies are determined by extrapolation. Over/Up sampling can be used to shift quantization noise to ultra-sonic territory, thus ensuring DACs to reach 16bit resolution or beyond. |

[#12] 真的可將youtube convert to wav? https://en.wikipedia.org/wiki/Oversampling The term oversampling is also used to denote a process used in the reconstruction phase of digital-to-analog conversion, in which an intermediate high sampling rate is used between the digital input and the analogue output. Here, samples are interpolated in the digital domain to add additional samples in between, thereby converting the data to a higher sample rate, which is a form of upsampling. When the resulting higher-rate samples are converted to analog, a less complex/expensive analog low pass filter is required to remove the high-frequency content, which will consist of reflected images of the real signal created by the zero-order hold of the digital-to-analog converter. Essentially, this is a way to shift some of the complexity of the filtering into the digital domain and achieves the same benefit as oversampling in analog-to-digital conversion. ------------------------------ in digital-to-analog conversion, the so-called oversampling actually doing interpolation to increase sample rate. that's upsampling oversampling is related to converting analog signals to digital at higher sampling rates than the target rate. that's it takes more samples per unit time from analog signals. hardware vs software is just a matter of implementation. nothing to do with methodology. |
