It makes a file, but I presume I have the options wrong (or I need a compile without 'libsndfile') because the result sounds awful. | lame -r -s 48 --little-endian - lame-test.mp3 WARNING: libsndfile may ignore -r and perform fseek's on the input. Compile without libsndfile if this is a problem. Assuming raw pcm input file LAME 3.100 64bits (http://lame.sf.net) Using polyphase lowpass filter, transition band: 16452 Hz - 17032 Hz Encoding <stdin> to lame-test.mp3 Encoding as 48 kHz j-stereo MPEG-1 Layer III (12x) 128 kbps qval=3 -- John. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
