I think one big reason nobody uses 44100 is that when you pull up/down you drop/gain .001 seconds of audio samples. That works out nicely with 48000 because the difference works out to +/-48. But with 44100 you get a fractional +/-44.1 samples which doesn’t work. And I think most broadcast engineers would not be too fond of the idea of dropping the audio fidelity to 32k. -Reube n _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
