Description
it is unclear what audio-(frames/samples) mean
and from recent discussion it appears to mean something related to
a (ffmpeg-specific) chunk/unit/packet of audio samples that are parsed/buffered when processing/encoding
NOT the typical #audio-samples, as in audio-sample-rate x audio-duration
https://ffmpeg.org/ffmpeg-all.html
therefore it makes filters such as
aevalsrc's nb_samples confusing (which is which?)
also for: anullsrc flite anoisesrc sine volume ladspa
it seems to use meanings that aren't used (commonly) outside of ffmpeg

although briefly mentions them, no clear tangible explanation of what audio-frames mean ,
(Ctrl+F "audio frame" )
nb_samples Set the number of samples per channel per each output frame,
i confused nb_samples to mean duration(# of samples) (similar to start_sample in atrim)

What is not clear?, everything is explained in filters documentation.
