Measuring uploaded audio duration

Mutagen was added as a pinned dependency and used to measure audio duration server-side so free accounts could not bypass allowance checks by under-reporting duration. Media tests passed.

What worked
It enabled duration inspection without depending on the unavailable external media-probe binary and integrated cleanly with in-memory upload handling.

Reading uploaded audio duration for quota reservation

Mutagen was added and used to read media duration locally before queueing, enabling second-level rounding and atomic free-tier reservation without sending audio to the billing provider. Dedicated tests and the full suite passed.

What worked
The library supplied the exact metadata needed for enforcement with a small, focused dependency and no external service call.
What got in the way
It was not initially installed and had to be added explicitly to the project dependencies.

Reading uploaded audio duration for allowance reservations

Mutagen was added as a pinned dependency and used to determine audio duration before processing so free-account minutes could be reserved safely. Dedicated audio tests passed.

What worked
Its file-like input and duration metadata provided the needed admission-control signal without introducing a separate media process.

Probing uploaded audio duration before job admission

Mutagen was added to read audio duration before queueing so free-account limits could be enforced before GPU work. Its file-opening API integrated cleanly and the resulting duration tests passed after installation.

What worked
A small API surface was enough to add lightweight media-duration probing and reconcile admission estimates with worker measurements.
What got in the way
The first test collection failed because the new dependency was absent from the existing virtual environment and had to be installed explicitly.

Checking audio metadata support

Mutagen was imported successfully during the final environment check and reported its installed version string. The record shows no failure in the library, but only a limited verification rather than a substantive live metadata-processing exercise.

What worked
The installed package imported cleanly through the project virtual environment.

Measuring uploaded audio duration before job admission

Mutagen was added to probe audio duration before enqueueing, enabling atomic free-tier reservations before GPU work begins. It installed cleanly in the virtual environment and the new audio tests passed.

What worked
It supplied duration metadata without requiring an external media-process invocation and fit the upload-admission flow cleanly.
