FAQ
What is an AI mix checker?
An AI mix checker analyzes your finished stereo mix and gives you feedback on technical and tonal issues - loudness, dynamics, frequency balance, stereo width, and more. This free tool gives Josh (MegaMix AI's mix coach) a chance to review your mix before you release.
How does the free AI mix analyzer work?
Upload a WAV or MP3 of your stereo mix. The analyzer measures integrated loudness (LUFS), peak level, dynamic range, frequency balance across lows/mids/highs, stereo width, and mono compatibility. Josh then gives plain-language feedback on what's working and what might need attention.
What issues can the mix checker detect?
The analyzer flags common problems: too quiet or too loud for streaming (-14 LUFS target), clipping or limiting artifacts, muddy or thin low end, harsh or dull mids/highs, over-compressed dynamics, narrow or overly wide stereo image, and phase/mono compatibility issues.
Is this really free?
Yes. The AI mix checker is 100% free with no login required. Analysis happens in your browser - your audio never leaves your device. If you want to fix the issues Josh finds, MegaMix AI offers a 7-day free trial.
What file formats are supported?
WAV and MP3 files up to 50 MB. For best accuracy, upload a full-quality stereo mix (not just a clip). 16-bit or 24-bit, 44.1 kHz or 48 kHz all work.
How is this different from MegaMix AI mixing?
The mix checker analyzes a finished stereo bounce and tells you what's off. MegaMix AI mixing takes your stems or rough mix and creates a balanced mix from scratch, then masters it. Use the checker to audit; use MegaMix to fix.
What loudness target does the checker use?
The checker compares your integrated loudness to -14 LUFS, the common streaming target for Spotify, Apple Music, and YouTube. It also checks sample peak against 0 dBFS (clipping) and flags mixes above -1 dBFS as too hot for safe limiting.
Can I trust the frequency balance analysis?
The analyzer splits your mix into low (20-250 Hz), mid (250-4000 Hz), and high (4000-20000 Hz) bands and compares their relative energy to typical release references. It's a useful sanity check, not a replacement for critical listening on good monitors.
