Vocos
The 24 kHz waveform decoder in every bundle (litert/, onnx/, webgpu/, coreml/, coreai/) and in pytorch/vocoder.pt is
fine-tuned from the Vocos model charactr/vocos-mel-24khz (https://github.com/gemelo-ai/vocos).

BigVGAN
The singing waveform decoder (vocoder_bigvgan components in litert/, onnx/, coreml/, coreai/, and pytorch/bigvgan_v2.pt) is
fine-tuned from the BigVGAN v2 model nvidia/bigvgan_v2_24khz_100band_256x (https://github.com/NVIDIA/BigVGAN).
