If you record a sentence at a normal speed

but play it at twice the speed, not only does the sentence end in half of the time (meaning the tempo is quicker), you will also hear the pitch go higher. The voice of an adult will sound like a child. Sometimes changing both tempo and pitch simultaneously is unwanted, that' why people come up with other more advanced functions: changing pitch without changing the tempo, and changing tempo without changing the pitch.

• 改變speed同時改變tempo與pitch我可以理解, 但改tempo不改pitch我不理解如何做到的. -移花接木- ♂ (0 bytes) () 04/06/2022 postreply 14:00:01

• 這個是專門的音樂軟件，比如midi時，你的曲子的tempo是可以改變的。每個音符的pitch不變。唱歌的聲音是單獨一軌。 -梅雨潭- ♂ (0 bytes) () 04/06/2022 postreply 15:55:16
