To investigate the "hiss" issue using WMP as a player and also varying quality settings and bitrates.
To convert an m4a files into mp3 using faad, use the following commands issues from a command prompt. The following command converts the file test.m4a into a raw WAV file test.wav. faad -w -f2 test.m4a >test.wav The following command converts the raw WAV file test.wav into an MP3 file test.mp3 lame --resample 44100 -q 2 -b 320 -x -r test.wav test.mp3 The option after "-q" is the quality of compression (1=slow good, 9=fast,poor) and the values after "-b" is the bit rate. You can also compare against the standard SC conversion using mov123 The following command converts the file test.m4a into a raw WAV file test.wav using mov123. mov123 test.m4a >test.wav The WAV->MP3 conversion is similar but I think you need to omit the "-x" lame --resample 44100 -q 2 -b 320 -r test.wav test.mp3 -- bpa ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=53021 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
