Question 1

Is AI Master My Song really free?

Accepted Answer

Yes — four mastering presets (Warm, Punchy, Balanced, Club) are completely free, up to 5 tracks per day, no account needed. Pro presets and unlimited masters are available on a $9/month subscription.

Question 2

How does AI mastering work?

Accepted Answer

Your track is processed through a chain of digital signal processors: high-pass filter, multiband EQ shaping, bus compression, stereo widening, ITU-R BS.1770 LUFS normalization, and a true-peak limiter. Each preset configures these stages for a specific sonic character — warm and analog, punchy and forward, neutral reference, or club-loud.

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 delivered as a 320 kbps MP3. Pro users can also download 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 focuses on instant, free mastering with no signup required. Free users get 4 expressive presets and 5 tracks per day; LANDR's free tier is limited to one preview download per month. Quality-wise the engine uses real ITU-R BS.1770 LUFS 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.
