High-quality sound Engine

[LGHRM]

I would like the feature that if the recorded audio of UTAU VB is of high quality, such as 24bit/48kHz, the output audio will be of high quality as well. (Sorry for DeepL English)

this is dependent on resamplers, meaning every resampler dev would have to add support, which is not likely as most resamplers have ceased development

[BagelHero]

What nagotown said is true... However, it is possible to implement new renderers like WORLDLINE-R... Perhaps a new renderer might be able to have support for variable bitrates. Unfortunately, I think the difference in audio output quality would be minimal as most of the quality issues associated with UTAU are to do with the method of re-timing and re-pitching samples, rather than the samples themselves.
