AI Mastering

Introduction

AI Mastering is a free online audio mastering service that uses artificial intelligence to automatically analyze and master your music tracks. Professional audio mastering has traditionally required expensive studio engineers and thousands of dollars per album. AI Mastering democratizes this process by offering automated, high-quality mastering that musicians, producers, and podcasters can access directly from a browser, with a free plan available for basic mastering needs.

AI Mastering supports common formats including WAV, AIFF, and FLAC. After uploading, the AI analyzes your track and applies mastering processing automatically. Within a few minutes, you can preview the mastered result and download it. The free plan provides basic mastering without a paid subscription.

First Project Tutorial

After signing up, navigate to the upload section on the dashboard. Upload a mixed but unmastered WAV file of your track. AI Mastering will scan the frequency content, dynamic range, and loudness of your audio. Within a few minutes, the mastered version will be ready for preview. Click the play button to A/B compare the original and mastered versions. If the result meets your expectations, download the mastered file. For platform-specific releases, adjust the target loudness setting to match the recommended levels for Spotify (-14 LUFS), YouTube (-13 LUFS), or Apple Music (-16 LUFS) before mastering.

Best Practices

• Upload clean, mixed tracks without any limiting or clipping on the mix bus for best mastering results.
• Set the target loudness appropriate to your distribution platform before processing.
• Compare the A/B preview carefully before downloading to ensure the AI mastering suits your genre.
• Use the offline version for batch processing large numbers of tracks without queue wait times.
• For critical releases, consider using AI mastering as a reference starting point and fine-tune with a professional engineer.
