Every sample library hides a question: where does the sound end so it can begin again? Every printed code hides another: will this still scan when part of it is gone? Seamcode answers both with numbers.
Audit the seam
Import-style seeds or build a fresh pad, then drag the loop region on a real waveform. Seamcode measures the seam the way your ears do, but with better memory:
- Seam K — how many "normal sample steps" the jump at the seam is worth. Under 2, you will never hear it.
- Wrap — the loudness step when the loop wraps around, in dB. A crossfade can hide a click; nothing hides a 6 dB jump.
- Period correlation — is your loop a whole number of cycles, or is it drifting?
- Snap — one tap moves the loop end to the cleanest same-slope zero crossing within your tolerance, and tells you exactly how far it moved.
Each loop gets a verdict — PASS, WARN, or FAIL — with a reason code like `preFadeClick` (the raw seam clicks, but your crossfade erases it on export) or `levelStepHard` (fade cannot fix loudness). Tail-gated drum loops are measured with the wrap check waived, honestly labelled in the report.
Export the looped region as WAV with the equal-power crossfade baked in, plus markers JSON, waveform SVG, and a plain-text seam report.
Audit the symbol
Encode EAN-13 with full L/G/R pattern tables and check-digit validation, or QR codes up to version 4 with all four error-correction levels. Under the hood Seamcode runs real Reed–Solomon over GF(256): every symbol it builds is verified by decoding it back — syndromes must vanish and the payload must return intact before the verdict says PASS.
- Capacity bar shows bytes used against the version ceiling before you type the last character.
- Mask selection follows the standard penalty rules (runs, blocks, finder look-alikes, dark ratio) — or lock any of the eight masks by hand.
- Live preview always renders black on white, the way the printed symbol will look, with a configurable quiet zone.
- Export SVG, PNG, module matrix TXT, and a report listing version, codewords, spare bytes, and penalty scores.
One idea, two domains
Loop points and error-correcting codes are the same story told twice: discrete data that must survive a cut. The Audit tab puts them side by side — every clip and every symbol with its metrics, verdict, and reason code — and writes the whole ledger out as one report. Nothing is scored by vibes; every PASS has a number behind it.
Samples included
Seamcode ships with three synthesised loops — a clean 120 BPM pad, a drum loop dragged deliberately out of phase, and a fading wash whose wrap betrays it — plus an EAN-13 reference and two QR tags. Together they demonstrate all three verdicts on first launch, so the app teaches its own thresholds before you touch anything.
Private by construction
No network access. No analytics. No account. Your audio and your codes never leave the device, and the privacy manifest declares exactly that: no tracking, no collected data.
For sample-pack builders, live performers, label printers, and anyone who believes "it sounds fine" is not a measurement.
