一首歌竟然能有多種風格？谷歌的新技術燃炸了

Facebook's AI Research (FAIR) division has created the neural network capable of hearing, for example, a jazz band play a song, and then is able to output that exact song in a completely different style of music, say, as if played by a punk rock band.
臉書的人工智能研究（簡稱FAIR）部門創造出具有聽覺能力的神經網絡，比如一首爵士樂隊演奏的歌曲可以轉化成一種完全不同的風格，像是朋克風格的演奏。

The result is nothing short of jaw-droppingly impressive–something even Facebook's AI researchers aren't shy of boasting about: Our results present abilities that are, as far as we know, unheard of.
轉化的效果除了震驚還是震驚，連臉書人工智能的研究者也毫不保留地對此稱道：我們展示的這項技術據我們所知應該是沒有人聽說過。

Asked to convert one musical instrument to another, our network is on par or slightly worse than professional musicians. Many times, people find it hard to tell which is the original audio file and which is the output of the conversion that mimics a completely different instrument.
談到歌曲在不同樂器轉換時，研究人員表示我們的這項技術和專業音樂人相比，旗鼓相當或稍遜色一點而已。人們很多次都聽不出哪個是原版哪個是由完全不同樂器的翻奏。

You can listen to a series of original inputs (songs played by a real band) and the AI's outputs (the same song then translated into a different style) in the following video. Jump to the 4:14 mark to see a great example where an original MIDI of Elvis Presley's “Always On My Mind” is translated into a symphony piece as if it were played by Mozart.
你可以在下面的視頻中聽一系列的原聲帶（也就是由真人樂隊演奏的歌曲）以及聽通過AI技術輸出的不同風格的音樂輸出音頻。跳到視頻的4:14秒，你就能聽到由埃爾維斯·普雷斯利演奏的《永遠在我心中》的原聲帶被完美地翻奏成就好像是由莫扎特演奏的交響樂。
