Kirin Mastering launches Kirin OS 1.0 for audio measurement and comparison

Kirin Mastering released Kirin OS 1.0 on July 22 for macOS and Windows, offering local audio measurement, song-based record keeping and a 14-day full-featured evaluation. The app is built to help producers compare versions, inspect audio events and keep stems, notes and credits tied to each song without uploading files to a cloud service.

Why it matters: - Kirin OS is built for engineers and producers who want to compare audio changes without losing the context behind each decision. - The app keeps measurements, versions, stems and production records together by song, which can make revisions easier to review and hand off. - The software works locally, so audio files and records stay on the user’s device.

What happened: - Kirin Mastering released Kirin OS 1.0 on July 22, 2026. - The desktop app is available for macOS and Windows. - The product includes a one-time purchase option and a full-featured 14-day evaluation. - Daisuke Nishio, founder of Kirin Mastering, described the product as a tool for making final music decisions with “your own ears.”

The details: - Kirin OS does not process or alter audio. - The app measures files, returns users to recorded timecodes for listening, and saves the resulting records with the song. - READ shows loudness, True Peak, phase, width, crest factor and loudness range on a timeline. - INSPECT lists detected hiss, click and crackle events by timecode. - Versions stores revisions of a song in one Work and allows playback to switch from the same position. - MASKING shows where multiple files overlap across time and frequency bands. - Kirin Hypha, the free companion plug-in, records PRE and POST measurements inside a DAW. - TRACE in Kirin OS lets users review those PRE and POST records as absolute values and differences while listening. - Works keeps measurements, stems, versions, artwork, credits, notes and related files together. - Stage organizes live-show information and can exchange that information as HTML between performers and venues. - The app uses Nishio’s “Keep the bug” approach, which records measurements without labeling results as good or bad.

Between the lines: - Kirin OS is positioned as a documentation and comparison tool rather than an automated audio fixer. - The product’s focus on timecodes, versions and song-level records suggests an emphasis on repeatable review across production stages. - The no-cloud approach may appeal to users who want to keep audio assets and production notes fully local.

What's next: - The full-featured 14-day evaluation begins when its license is first activated. - No payment information, subscription or automatic billing is required for the evaluation. - Saved Work and measurement records stay on the device, and activating a permanent license preserves them. - Kirin OS 1.0 supports macOS 12 or later on Apple Silicon and Intel Macs, and Windows 10 or 11 x64. - A license can be used on up to three devices. - The Launch Menu price is US$297 through Sept. 30, 2026, then US$497 starting Oct. 1. - Kirin Sense is US$39 during the same period, and Kirin Hypha is free. - The Kirin OS product page includes the evaluation, permanent license, current system requirements and a 93-second walkthrough using application screens and audio. - The Kirin OS 1.0 press kit includes release facts, product images and downloadable media assets. - More information is available on the Kirin OS product page and the Kirin Hypha page.

The bottom line: - Kirin Mastering is betting that audio professionals want measurement tools that preserve context, keep work local and make version-to-version comparison easier.
