Analysis Credits Explained

What "Analyze on Upload" does, how analysis credits work, and why re-importing an Ableton file never costs you one.

Analysis is the thing you came to Pliris™ for. It's what turns a folder of raw stems into a fully programmed song — no tapping tempo, no transcribing lyrics, no marking sections by hand. This article explains what it does and how the credits behind it work.

What "Analyze on Upload" does

When you upload stems into an arrangement, look for the "Analyze on Upload" toggle before you confirm. When it's on, Pliris listens to your stems and automatically extracts:

  • Key — the song's key signature.
  • Tempo — the base BPM (and a full tempo map for warped material).
  • Time signature — 4/4, 6/8, whatever the song is in.
  • Lyrics — auto-extracted and time-synced, with the current line highlighted during playback.
  • Chords — chord data rendered as a chart that follows playback.
  • Song sections — Intro, Verse, Chorus, Bridge and the rest, placed on the timeline so you can jump between them.

All of it, from the stems alone. When analysis finishes, your key, tempo, and time signature populate, and the Lyrics and Chords tabs fill in. Anything that came through wrong you can edit by hand.

Pro tip: Rename your stems before analysis kicks off — Guitar, Lead Vocal, BGVs, Synths, Drums — so Pliris routes each one to the right group. Not sure what a stem is? Click into it and press Shift + Space to preview it. Press Tab to jump between stem names quickly.

How credits work

Each song analysis uses one credit. That's it — one credit covers the full extraction of key, tempo, time signature, lyrics, chords, and sections for that arrangement.

  • Free accounts: 3 credits per month.
  • Paid accounts: 35 credits per month.

One credit per analysis, so a free account can fully analyze three songs a month at no cost, and a paid account can do thirty-five.

Re-importing Ableton does NOT cost a credit

Here's the part worth remembering. After you download an arrangement as an Ableton Set and make edits in Live — relabeling a section, tweaking the arrangement — you'll come back to Pliris and re-import the .als file to sync your changes.

That re-import does not use a credit.

If you're out of credits, you'll see a warning when you upload the file. Ignore it. Re-importing an .als isn't re-analyzing anything — there are no stems to listen to and nothing to extract. It's just pulling your section changes back into Pliris so the app and your Ableton session stay in sync. It's essentially instant, and it's free every time.

Credits are spent on analysis of audio (the "Analyze on Upload" pass on your stems), not on syncing an Ableton file back in.

When to spend a credit

Spend a credit when you have new audio Pliris hasn't heard yet — a fresh set of stems, or a new arrangement of a song you want fully analyzed from scratch.

Don't spend one to:

  • Re-import an edited .als file (free — see above).
  • Edit lyrics, chords, or section labels by hand (editing analyzed data is always free).
  • Play back, mute, solo, or rehearse an already-analyzed arrangement.

Frequently asked questions

How many analysis credits do I get each month?

Free Pliris accounts get 3 analysis credits per month and paid accounts get 35 per month. Each song analysis uses one credit, so a free account can fully analyze three songs a month at no cost, and a paid account can do thirty-five.

Why do I see an out-of-credits warning when re-importing an Ableton file?

The warning appears on upload when your credit balance is empty, but you can safely ignore it — re-importing an .als file never uses a credit. There are no stems to analyze; Pliris is just pulling your section changes back in so the app and your Ableton session stay in sync, and it's free every time.

Does editing lyrics, chords, or section labels cost a credit?

No. Editing already-analyzed data by hand is always free in Pliris — credits are only spent on the "Analyze on Upload" pass over new audio.

What does one analysis credit cover?

One credit covers the full analysis of one arrangement: Pliris extracts the key, tempo (including a tempo map for warped material), time signature, time-synced lyrics, chords, and song sections from your stems alone.

When should I spend an analysis credit?

Spend a credit when you have new audio Pliris hasn't heard yet — a fresh set of stems, or a new arrangement you want fully analyzed from scratch. Re-importing an edited .als, editing analyzed data by hand, and playing back an already-analyzed arrangement are all free.
