Every entry point that conditions on a reference clip now takes the
waveform in memory: the vendored loaders gained load_audio_at (path,
ndarray or tensor -> float32 mono at the target rate, soundfile +
torchaudio, no librosa), and the resamples ride the new dsp module. The
node hands over preprocess_comfy_audio output at the right rate per
site (S3Gen 24k for conditioning, the tokenizer's 16k for the VC
source), so temp_wav_path and its temp-file machinery are gone -- which
also removes the 16-bit PCM quantization the file round-trip imposed.
Resampling is the one deliberate numerical difference: torchaudio's
sinc kernel instead of soxr, touching only clips supplied at call time.
The built-in-voice shared-assets E2E stays byte-identical
(md5 370acf3f9469d55759c3d6096b2628ff); the reference-clip E2E changes
measurably in the last digits, as expected and reported.
