What is AI Mastering?
AI Mastering is an automated audio mastering service that uses an open-source AI algorithm to process and enhance audio files. Accessed via a drag-and-drop web interface or an offline application, its core mechanism employs a proprietary limiter to balance loudness and dynamic range. The system provides detailed spectrum and loudness analysis, allowing for precise customization of target loudness and mastering levels. It supports high-resolution audio (up to 24kHz with a 48kHz+ source) and includes a dedicated bass preservation option for low frequencies. The tool is designed for independent musicians, podcasters, and audio producers who need a quick and consistent final master. For instance, a musician can upload a final mixdown from their digital audio workstation to create a release-ready track, adjusting loudness to meet specific streaming service requirements. A podcaster can process an episode's audio to normalize volume levels and improve clarity, ensuring a professional sound for their audience before final export and distribution across listening platforms.
