Is FFTFrame giving the full Fourier Transform of one time-boxed section of the music, or one time-boxed part of the full Fourier Transform of the music?

The clarify: in my head there is a certain music track that I feed into this library. When I get an array of FFTFrames back, is each FFTFrame a Fourier Transform of the next, say, 1ms of the music? Or is each FFTFrame a 1ms chunk of the full Fourier Transform of the whole music? I guess a Fourier Transform would be different for 1ms of a song than for the whole song, so I'm confused which one this is. Thanks!

The array of FFTFrames would be a Fourier Transform of the next window of music (the former rather than the latter in your question).
