SPIRAL vs the Alternatives
Why free, local, browser-based mastering beats upload-based subscriptions. An honest, data-backed comparison.
SPIRAL wins on price, privacy, and control
Free forever · Full mastering chain · Local processing (no uploads) · Built by a real producer
Why SPIRAL Wins on Privacy
LANDR, eMastered, and BandLab all require you to upload your audio to their servers. For unreleased tracks, stems, or client work, this is a non-starter. SPIRAL processes everything locally in your browser using the Web Audio API. Your tracks never leave your machine. No data is stored or tracked , ever.
Why SPIRAL Wins on Control
LANDR and eMastered are "black box" AI mastering , upload a track, get a result, no adjustments. SPIRAL gives you a full professional mastering chain: High-Pass Filter, Corrective EQ, Saturation, Compression, Tonal EQ, Mid/Side control, and brickwall limiting , all with real-time metering (LUFS, true peak, stereo correlation, RMS).
Why SPIRAL Wins on Speed
Upload-based services mean waiting. Upload, process, download, listen, re-upload if you want changes. SPIRAL is real-time. Every adjustment is audible immediately. A/B between original and mastered with one click. Loop a section and tweak until it is perfect , no waiting, no re-uploading.
Why SPIRAL Wins on Price
SPIRAL is free forever , no trial, no credit card, no "pro tier" paywall. LANDR starts at $9/month. eMastered at $13/month. Even BandLab's free tier pushes you toward paid features. SPIRAL has no such limitations: unlimited tracks, full chain access, reference matching, AI analysis , all free.
When SPIRAL Is the Best Choice
