Baxandall EQ/Baxandall 3 Band EQ

The Baxandall EQ is a smooth, wide-band tone control circuit widely used in audio systems, offering gentle boost or cut for bass and treble frequencies. Its simple design and musical response make it ideal for achieving natural tonal adjustments. Implementation is using the standard shelf filter equations from the Audio EQ Cookbook by Robert Bristow-Johnson

Parameters:

audio self explanatory...
bass_gain_db Bass gain in decibels
mid_gain_db Mid gain in decibels
treble_gain_db Treble gain in decibels
low_freq : The corner frequency for the low shelf (e.g. ~100 Hz).
mid_freq : The center frequency for the mid peaking filter (e.g. ~1 kHz).
high_freq : The corner frequency for the high shelf (e.g. ~10 kHz).
mid_q : Quality factor for the mid peaking band. Adjusting Q controls the bandwidth of the mid peak. A typical Q might be 0.7 for a broad bell.

Enhance Harmonics

Harmonic enhancer boosts selected harmonics to enrich the sound.

Parameters:

harmonincs comma separated numbers of harmonics to boost
mode whether to automatically detect base frequency based on an audio or use manual setting
base_frequency base frequency to use in manual mode
gain_db How much to boost harmonics
gain_db Width of the filters

Normalizer

Normalizer is an amalgamate of multiple normalization approaches, including Loudness Units Full Scale (LUFS) with standard default set to -14db.

Parametes

audio_input: audio input
mode: "lufs","rms","peak","auto"
target_rms: The desired RMS value for the audio signal. Default is 0.1, which corresponds to a moderate average signal level.
target_lufs_db: The desired loudness level in LUFS. Default is -14.0, which is a common loudness target for streaming platforms like Spotify.
target_peak: The desired peak amplitude for the audio signal. Default is 0.9, meaning the loudest sample will be scaled to 90% of the maximum possible amplitude.
target_auto: The desired amplitude level for the audio signal. The algorithm scales the audio to match this level. Default is 0.7 (normalized scale from 0 to 1).
target_auto_alpha: The smoothing factor for the gain adjustment. A smaller value of alpha makes the gain adjustment slower and smoother (avoiding sudden jumps). A larger value makes the gain adjustment faster but potentially introduces abrupt changes.

Loudness

The get_loudness function calculates the integrated loudness of an audio signal in LUFS (Loudness Units relative to Full Scale). This is a perceptual measure of loudness, taking into account the human ear's sensitivity to different frequencies and the entire audio signal's duration.
