### Single Speaker (8x upscaling)

Next, we look at 8x upscaling. Again, the super-resolution algorithm recovers a large fraction of the high frequencies.

### Sample 1

### MultiSpeaker (2x upscaling)

Next, we look at the more interesting setting where we train on one set of speakers, and test on a second set of speakers. At 2x upscaling, the task is not too difficult and our methods reconstructs almost perfectly the original sample.

### Multispeaker (4x upsampling)
### MultiSpeaker (4x upscaling)

Next, we look at the more interesting setting where we train on one set of speakers, and test on a second set of speakers.
On the more interesting 4x task, our output is slightly noisier, but it also clearly outperforms the baseline.
