The record

What it does: DDSP-SVC is an open-source project for real-time singing voice conversion.
Local processing: The README describes installing dependencies and running the conversion GUI locally with Python.
Real-time conversion: Its real-time interface uses sliding windows, cross-fading, SOLA-based splicing, and contextual semantic reference.
Offline conversion: The command-line interface converts an input WAV file to an output WAV file and accepts pitch-shift and speaker options.
Model training: The project documents preprocessing audio datasets and training a model with a rectified-flow script.
Multi-speaker support: Training supports multi-speaker models configured with a speaker count and speaker-numbered audio folders.
Model components: The setup instructions support ContentVec or HubertSoft encoders, an NSF-HiFiGAN vocoder, and the RMVPE pitch extractor.
Integrations: The README recommends installing PyTorch and documents TensorBoard for viewing training status and generated test audio.
Hardware and setup: The README says its default configuration suits 44.1 kHz training with an RTX 4060 and reports a working Python 3.11, Windows, CUDA 13.0, PyTorch 2.9.1, and torchaudio 2.9.1 setup.
Dataset guidance: The project recommends about 1,000 training clips and about 10 validation clips, with each audio clip at least two seconds long.
Data and legal use: The author asks users to train only with legally obtained authorized data and not use models or generated audio for illegal purposes.
Intended users: The project describes its goal as developing free AI voice-changer software that can be used on personal computers.
