Sound Resynthesis

A good analogy to keep in mind when Resynthesizing is: 'Load, Aim and Fire'.That is, 'Load' the sample, 'Aim' by adjusting the Resynthesis controls and 'Fire' by sending the sample to the desired Keyboard Zone.

If desired you can change the import resolution by selecting the RESOLUTION (Normal, High, Best) options in combination with the 'Import charged sample' step.

If you have resynthesized a sample and the sound is still out of tune (and you have set the Resynthesis DETUNE range to the max) the following method may help: 6.1 If you don't need to preserve Detune settings on other Spectra, turn down the 'Control Range' Detune slider (on the main interface) to the minimum setting.

BALANCE - Adjust the TEST playback balance between the original sample (fully left) and the resynthesized sound (fully right).

The default is a 50/50 mix of the original and resynthesized sounds and is a good starting position as you use the Note & Detune controls to fine-tune the tone of the resynthesized sound to match the original.

The optimization criterion in VAEs being the sum of the reconstruction error and a regularization term, it naturally leads to a lower reconstruction accuracy than DAEs but we show that VAEs are still able to outperform PCA while providing a low-dimensional latent space with nice "usability" properties.

We also provide corresponding objective measures of perceptual audio quality (PEMO-Q scores), which generally correlate well with the reconstruction error.

Note that you can load your own custom Noise Samples to the library if needed.

'Fire', shoot the resynthesized sound to a Zone: Open the SPECTRUM menu and import the Spectra into the selected Zone (Import charged sample).

CHARGE SMP - Charge Sample opens a Load Dialog to browse and load (Charge) samples.

Clicking the button again when a sample is loaded will 'Uncharge' the sample, clearing it.
