Use case
Separate film audio into dialogue, background music and effects for dubbing and post-production mixing.
Choose a model for your material and purpose, and review the examples before submitting.
Cost, time, formats and parameters depend on the selected model.
Include the tool name, steps and the problem in your feedback. Screenshots can help us locate it.
Export dialogue, music and effects as three stems for dubbing, video editing and background remixing.
A band-split network separates dialogue, music and effects; compare dialogue leakage and background detail.
A time-frequency model for three film stems; this is TIGER DnR, distinct from the two-speaker TIGER model.
Separate film and video audio into dialogue, music, and sound effects. Outputs 44.1 kHz mono audio; stereo input is downmixed to mono first.

3 output categories
Only records with verified public inference implementations and matching weights are shown; algorithms requiring no weights are also eligible. Closed services, unreleased weights and unmatched experiment versions are excluded. This is not an all-model leaderboard.
Each set of weights appears once per benchmark, using its best published result for the selected metric. An overall score comes from one evaluation. Expand to compare evaluations and settings.
Public weights do not establish a fully open-source license. Expand the data for declared weight licenses and access conditions. Undeclared licenses are marked separately.
Markers identify models or components used here. Scores and settings come from the cited tests, not a new evaluation of the complete site pipeline.
Choose a dataset to view all metrics for each model. Rows follow the official rank or selected metric. Bold marks each column’s best comparable value, including ties. Different evaluation protocols are ranked separately; missing scores are shown as -.

A complete public inference package for these experiments has not been verified. Other weights with the same model name do not qualify.

SI-SDR reported by the authors on 973 complete DnR v2 test tracks. Each model uses its official window and hop; the mean covers music, speech and effects. These are not TelkNet measurements and are kept separate from other datasets or training setups.
