Using ffmpeg to optimize vocals in recordings – any advice?
Hello. We need to use ffmpeg to remove non-vocal frequencies from audio files in order to make the voices in the recordings easier to hear. ffmpeg offers various ways to do that, including bandpass, highpass, basscut, equalizer, all of which could potentially do the job. Trouble is the explanations ( https://ffmpeg.org/ffmpeg-filters.html ) are extremely technical and despite my best efforts I haven’t been able to figure them out. I think all we really need to do is reduce or remove all sound at frequencies below, say, 200 Hz. Does anyone know how to convert that requirement into the ffmpeg parameters? Thanks!

thanks reuben! ffmpeg’s documentation is somewhat cryptic and something like this is just helpful. 😀
