Description

The standard broadcast chain: a high-pass to kill rumble, optional 60/120/180 Hz hum notches plus FFT denoise, a 4:1 compressor, loudness normalisation to target_lufs, and short in/out fades.

Usage

broadcast_audio(input, output, dehum = TRUE, target_lufs = -14, fade = 0.06,
                highpass = 80, overwrite = TRUE, dry_run = FALSE)

Arguments

input	Path to input audio (or A/V) file.
output	Path for output file.
dehum	Apply the 60/120/180 Hz hum notches + FFT denoise (default TRUE).
target_lufs	Integrated loudness target in LUFS (default -14).
fade	In/out fade length in seconds (default 0.06).
highpass	High-pass corner frequency in Hz (default 80).
overwrite	If TRUE (default), overwrite output file.
dry_run	If TRUE, return the FFmpeg command without executing.

Value

Invisibly returns the output path. If dry_run, returns command string.
