Field notes
The guide separates audio transcription from ordinary format conversion and describes the inferred MIDI output as a draft requiring manual repair. Its concrete installation notes include Python 3.7, librosa 0.9.2, and a documented PyTorch/CUDA dependency path. The page also distinguishes its benchmark context—clean, professionally recorded solo piano—from harder inputs such as phone recordings, mixed instruments, vocals, drums, and reverberant performances.
