--- Comment #4 from postix <[email protected]> --- (In reply to Bernd from comment #3) > Hmm, according to the ffmpeg libavfilter library, the valid range for gain > is -900 to 900. Yes, thanks for the hint! This range has been introduced with commit [1]. It tells us, that the units of gain is dB and the description reads in [2] > Give the gain at 0 Hz. Its useful range is about -20 > (for a large cut) to +20 (for a large boost).
