LANDR processes your track and hands back a finished master. SongTools' mastering tools tell you what's actually wrong with the one you already made. They solve different problems — here's how to tell which one you need.
Search for "AI mastering tool" and LANDR and SongTools can both show up, which makes them sound interchangeable. They aren't solving the same problem.
LANDR is an automated mastering *service*: you upload a mix, its algorithm analyzes it and applies processing — EQ, compression, limiting — and hands you back a finished master. You don't see what it changed or why; you get a file.
SongTools' mastering tools (Session Audit and Mastering Check) work the other way around. They analyze a mix you've already made — or already mastered elsewhere, including with LANDR — and tell you specifically what's off: loudness relative to streaming targets, frequency balance issues, phase problems, sections that don't sit right. Nothing gets processed for you. It's a second opinion, not a finished product.
Upload a mix, LANDR's algorithm processes it, you get a mastered file back. Pricing runs roughly $11–25/month depending on tier (unlimited masters at the higher end), or about $10 for a single one-off master. It's built for artists who want a finished master without hiring an engineer or learning mastering themselves — speed and convenience are the whole pitch.
The tradeoff is the same one with any black-box process: you get an output, not an explanation. If the result doesn't sound right, LANDR doesn't tell you *why* — you're stuck re-running it with different settings or reference tracks and hoping.
Session Audit and Mastering Check don't produce a mastered file. They analyze what you already have — loudness (LUFS) against real per-platform streaming targets, frequency and stereo balance, clipping and phase issues — and tell you specifically what to fix and why, in terms you can act on whether you're mastering it yourself, sending notes to an engineer, or deciding whether a LANDR pass actually got your track streaming-ready.
That also means SongTools isn't a replacement for the mastering step itself if you don't want to do it by hand — it's a diagnostic layer on top of whatever produced the mix or master you're checking.
- If you want a finished, ready-to-upload master with no manual work and you're comfortable not knowing exactly what got changed, that's LANDR's whole job.
- If you want to understand what's actually wrong with a mix or master — including one LANDR (or an engineer) already produced — before you release it, that's what Session Audit and Mastering Check are for.
- Plenty of artists reasonably use both: run a LANDR pass for the finished file, then check it against real streaming-platform targets before uploading.
LANDR trades transparency for speed — you get a result fast, but not an explanation. SongTools trades a finished file for that explanation — you still have to act on what it tells you, whether that's remixing yourself, adjusting settings, or briefing an engineer. Neither is strictly "better"; they're built for different points in the same workflow.
