AI Mastering API
Overview
AI Mastering is an API that automatically applies professional audio mastering to your music files using AI algorithms. You upload a track, choose your target loudness and style, and receive a mastered version back — no audio engineering expertise required. It is perfect for indie musicians and developers building music production tools.
Beginner Tip
Upload uncompressed WAV or AIFF files for the best mastering quality, as highly compressed MP3s limit what the AI can improve. Start with the default preset before customizing loudness targets to hear a reference result first.
