UnverifiedFor developers who need to use both text and reference audio simultaneously, a pragmatic approach is a combined pipeline: first generate base material with a text-to-audio model, then use audio processing or style transfer models to make secondary adjustments with the reference sample.75% similarUnverifiedSpectral mask methods typically process only magnitude information and reconstruct each stem's waveform using the phase information from the original mix, and this phase approximation introduces additional distortion when stems are heavily aliased.74% similarUnverifiedText-based methods flatten the word frequency distribution, increasing the occurrence rate of low-frequency features by 37% to 38%, thereby reversing errors on tones and palatalization.73% similar
