Tunebat vs SESSION™ Key
Tunebat analyzes files in a browser. SESSION™ Key also analyzes dropped files, and adds live Mac output, microphone input and supported DAW sends. The choice is no longer file analysis versus live analysis alone.

The workflow difference
Tunebat's analyzer provides key and BPM estimates, and its documentation says those calculations run inside the browser. Calling every browser analyzer an audio-upload service would misdescribe this tool. Tunebat also has a song database, which is a different source of information from analyzing a file.
For an occasional file, open the analyzer and check its result against the music. For repeated references across browser playback, files and the DAW, SESSION™ Key keeps those inputs in one menu-bar workflow. A database result should be matched to the exact recording or remix before using it.
SESSION™ Key at a glance
- Price
- $49 once
- Requirements
- macOS 14.4 or later on Apple silicon. One license covers up to three Macs.
- Input and setup
- Read system audio, use the microphone, or drop an audio or MIDI file on the menu bar. Live analysis follows the passage playing; a file gives the analyzer a different span of material.
- Working with it
- Optional Beta sends connect the reading to supported DAWs and Auto-Tune. The fields and setup vary by destination. Check the integration guide before purchasing for a particular send.
- Before the session
- The outline marks a locked reading; green and amber communicate confidence separately. A locked reading can still be uncertain. Listen, check the musical context, and use the half-time or double-time control when the pulse needs it.
Before the first session
A relative-major/minor disagreement needs a musical check. Neither a free price nor a paid license proves the key of an ambiguous passage.

Questions before choosing
Does Tunebat send analyzer files to a server?
Tunebat's analyzer page says its analysis runs inside the browser and files are not sent to another machine. That statement applies to the analyzer described there, not every service on the internet.
When should I choose SESSION™ Key instead?
Choose SESSION™ Key when a reference needs to become a reading beside your open Mac session, followed by a supported project send. Use Tunebat when its focused file or song-lookup workflow is all the job needs.
What does Tunebat cost compared with SESSION™ Key?
Tunebat key/BPM analyzer: Free basic analysis. Optional features have separate limits and prices. SESSION™ Key costs $49 once.
