How to yt-dlp extract youtube audio-only to 32-bit float 48000 .wav? [closed]
28 April 2024, by Rowe MorehouseMy use case: Extract just the audio from a youtube URL directly to a
.wav
at 32-bit float 48000.

Preferably without any post process args or secondary passes or after-the-fact conversion or muxing.


I want f32le, aka PCM_f32le, aka PCM 32-bit floating-point little-endian, which is supported by
ffmpeg
. Also want 48000 sample rate, as stated.

Is this possible?


My current command:


yt-dlp -f bestaudio --extract-audio --audio-format wav --audio-quality 0



What do I need to add to achieve my use case / job-to-be-done??
