Stemrail WAV Delivery

Stemrail prepares already-separated audio tracks for collaborator handoff on your Mac. Import two to 32 local mono or stereo sources, inspect measured peak envelopes, audition an original track, and set its leading offset, delivery gain and output name.

Choose 44.1, 48 or 96 kHz and 24-bit PCM or 32-bit float WAV. Stemrail converts differing source rates, adds the offsets as leading silence, and pads every output to the same exact frame count with your chosen common tail. The source files stay untouched. PCM export rejects samples above full scale; floating-point export can retain headroom.

Each delivery includes numbered WAVs, Delivery.csv, Verification.json and Read Me.txt. Stemrail reopens the rendered WAVs to check their rate, channels, encoding and exact length, and records SHA-256 hashes of source and output files. This checks files; it does not certify musical alignment, loudness or compatibility with a particular DAW.

Save reusable .stemrail sessions containing source-file references and delivery settings. Reopen a session to remeasure its audio, or replace a missing source. Session files do not include copies of your audio.

Inputs: WAV, AIFF, M4A and MP3 when macOS can decode them; mono or stereo at 8–192 kHz. Deliveries are limited to 60 minutes, offsets to 60 seconds per track, and common tails to 10 seconds. No source separation, automatic timing alignment, mixing, recording or loudness mastering.

No login, subscription, ads, analytics or cloud processing. Audio is read and exported locally to a folder you choose.
