Install requirements:

~ $ pip install -r requirements_dev.txt

To create a python package, go to inside tuned directory:

~ $ cd tuned

Build the package in an isolated environment, generating a source-distribution and wheel in the directory dist/ (https://build.pypa.io/en/stable/):

~$ python -m build

To install it:

~ $ pip install ./dist/tuned-0.3.0-py3-none-any.whl

Usage

Launch TunEd with standard tuning frequency (@440㎐):

~$ tuned

Global Parameters

• --frequency <int> / -f <int>: Sets the reference frequency for A4 (e.g., 442). Default: 440.
• --mod <mode> / -m <mode>: Chooses the detection mode.
• --verbose / -v: Increases the amount of information displayed.

Detection Modes

Note detection (default)

Detects a single note and displays its tuning accuracy.

~$ tuned -m note

• --monitoring: Activates audio monitoring (routes the input sound to the output).

Chord detection

Identifies the played chord and details its component notes.

~$ tuned -m chord

• --monitoring: Activates audio monitoring (routes the input sound to the output).
• --no-harmonics-identification / -nohi: Disables the identification of harmonics in chord analysis. This can improve performance but may reduce accuracy for complex chords.

Metronome

A visual metronome that displays the beat.

~$ tuned -m metronome

• --bpm <int>: Sets the beats per minute. Default: 60.
• --time-signature <n/d> / -ts <n/d>: Sets the time signature (e.g., '4/4', '3/8'). Default: 4/4.

Verbosity Levels (-v)

You can stack the -v flag to display more information.

• (no flag): Basic display for the selected mode.
• -v: Precision: Shows the tuning offset in cents.
• -vv: Frequency: Adds the frequency of the detected note(s) in Hz.
• -vvv: Signal Level: Adds the signal strength in dB.
• -vvvv: Execution Time: Adds the processing time for each analysis loop.
