I was thinking about adding full music in a animation, so I thought to myself if it can work, but I don’t think it’s gonna work
it’s gonna take a lot of frame stretching. you can add audio by clicking on the upload asset button and add your file, then dragging the audio asset into a frame if you don’t know how to stretch frames, you can drag the edge of a frame to extend it. then you just have to make the frame the same length of the song.
Also, something that can help is you can change the length of a frame in the inspector. Changing the “Frame Length” value to (FPS * Seconds in Your Song) will make the frame as long as your song.
