Kalmori accepts the following audio containers at upload: WAV, MP3, FLAC, AAC/M4A and OGG. Every upload is parsed as real audio — corrupt files, renamed non-audio files and clips shorter than 3 seconds are rejected immediately.

About MP3
MP3 uploads are accepted, but a lossy file cannot be improved later and some platforms treat lossy masters as lower quality. Whenever you have the WAV export, upload that instead.
What Kalmori stores
The exact file you upload is stored in full and delivered as your master. Kalmori does not shorten, re-encode or replace it. The duration shown after upload is measured from the real file.
Tip:
Tip: Export the master directly from your DAW or mastering session rather than converting an MP3 back to WAV — that does not restore lost quality.
