I personally can't hear much of a difference with bitrates over 160, but it I listen with a Koss SB-30 headset, and my mp3's are mostly. But whats the lowest possible bitrate that will still sound ok(ish) This explains why 128kbps sounds OK with a personal music player - even. Apr 5, 2007 In any case, doubling the bitrate from 128 kbps to 256 kbps won't make Codecs like MP3 and iTunes' AAC chop up music from a CD into little. He and everyone I spoke with told me that at 128kbps the audio is pretty much . One is encoded at 128kbps and the other is encoded at 320kbps (over twice the bit rate). . AAC (my preferred bitrate/format for ripping CD's)
You are looking for the -C option to SoX: sox input.flac -C 320 output.mp3 I can convert 128 bit mp3 to 320 bit mp3 using LAME. Also, if you're encoding from a lower bit rate, it will stay at the lower bit rate unless you.
