# Optional audio-transcription dependencies (Basic Pitch).
#
# Requires Python 3.11 on macOS. (basic-pitch's tensorflow-macos<2.15.1
# constraint excludes 3.12+ - no compatible tensorflow-macos wheel exists.)
# Linux is more flexible; 3.11 or 3.12 both work there.
#
# To enable MP3 / audio-to-MIDI transcription on macOS:
#   brew install python@3.11
#   /opt/homebrew/bin/python3.11 -m venv .venv
#   source .venv/bin/activate
#   pip install -r requirements-transcribe.txt
#
-r requirements.txt

# setuptools < 81 is required because basic-pitch's dependency `resampy`
# still imports `pkg_resources`, which setuptools 81 (released 2025) removed
# after years of deprecation. Until upstream resampy migrates to
# `importlib.metadata`, we pin to the last setuptools major that ships
# pkg_resources (80.x).
setuptools<81

# `[tf]` extra is REQUIRED since basic-pitch 0.4+ made the model backend opt-in.
# Without it, basic-pitch installs but `predict()` fails (no TensorFlow to load
# the ICASSP_2022_MODEL_PATH saved model). The `[onnx]` extra would be lighter
# (~10 MB vs TF's ~500 MB) but our service uses the TF saved-model format.
