The final output of the Demucs is influenced by both the configuration of the technical parameters and the quality of the source material. Professional users need to make sure that they get the best possible separation with the right settings, which is especially important in commercial grade applications.
Key quality influences include:
- Input Format: Lossless WAV files are recommended, lossy formats such as MP3 will lose high frequency detail.
- Model selection: htdemucs_ft fine-tuned model improves separation accuracy by about 151 TP3T compared to the base version
- Audio Characteristics: Complex arrangements require a larger segment value, it is recommended to set -segment 10 or more.
- Hardware configuration: GPU processing reduces artifactual noise by about 30%, especially effective for vocal separation
Tests have shown that processing 24bit/96kHz WAV files using the htdemucs_ft model results in separation quality approaching that of professional audio plug-ins on RTX 4080 graphics cards. This controllable quality allows Demucs to adapt to a wide range of needs from hobbyists to professional studios.
