Question 1

Is AI Master My Song really free?

Accepted Answer

Yes, completely free. No account, no credit card, no daily limits. Master as many songs as you want and download both the Free and Pro master styles as 320 kbps MP3 or 24-bit WAV.

Question 2

How does AI mastering work?

Accepted Answer

Your track is processed through a chain of digital signal processors: high-pass filter, gentle multiband EQ shaping, bus compression, stereo widening, ITU-R BS.1770 loudness normalization, and a true-peak limiter. The Free Standard Master is balanced and broadcast-safe; the Pro Master is streaming-loud with an air shelf and wider stereo.

Question 3

What audio formats are supported?

Accepted Answer

You can upload WAV, MP3, FLAC, AIFF or M4A files up to 35 MB. Output is available as a 320 kbps MP3 or a 24-bit WAV.

Question 4

Are my files stored on the server?

Accepted Answer

No. Audio is processed in memory and discarded immediately after the mastered file is delivered. We never keep your tracks.

Question 5

How is this different from LANDR or BandLab Mastering?

Accepted Answer

AI Master My Song is 100% free with no signup. LANDR's free tier limits you to one preview download per month. Quality-wise the engine uses real ITU-R BS.1770 loudness targeting and a true-peak limiter — the same metering standards professional mastering engineers use.

Question 6

How long does it take?

Accepted Answer

Around 5–15 seconds per track on a normal-length song. Bulk mode masters multiple tracks sequentially.
