HanoLab Mastering vs Quantara Music

HanoLab Mastering is a browser-based mastering tool within HanoLab’s broader set of AI audio tools for music generation, voice conversion and stem separation. It can move a mix toward a commercial reference’s loudness and tonal balance, or toward a streaming loudness target. Uploads can be MP3, WAV, FLAC or M4A, and mastered tracks export as lossless 24-bit WAV. Each mastered track uses one subscription credit; the listed REST API rate is $0.02 per track. The browser canvas combines generation, stem splitting, voice conversion and mastering without installation. The free plan includes 30 monthly credits, but its outputs expire after seven days and are for personal and evaluation use. Credits reset monthly, do not roll over, and generation pauses when they run out until renewal or upgrade. Paid plans start at $19.90 a month and grant a commercial license for outputs generated while the plan is active. Free accounts have model-improvement data sharing enabled by default; paid accounts have it disabled by default. Users can change that preference in Account Settings.
