How We Benchmarked 3 AI Vocal Removers with SI-SDR, SI-SIR, and SI-SAR

Disclosure: NeuralSound designed and conducted this benchmark. Moises and Fadr did not review or approve the test. The same input files and evaluation pipeline were used for all three services. Comparing AI vocal removers is harder than uploading one song and deciding which result sounds louder or cleaner. Cloud services may introduce timing offsets, export different file lengths, apply different output levels, and update their models without exposing a version number. A fair comparison…
