As described in the paper, we compare three audio-score alignment methods:
Here we show four examples, one for each polyphony. We show the results by time-warping the original mixture according to the output alignment of each score follower/aligner. You may follow the following steps to get a feel for these examples:
|Polyphony||Score||Original audio||Time-warped audio by SF-Pitch||Time-warped audio by SF-Chroma||Time-warped audio by Scorealign|
