![]() ![]() I guess MP4Box won't be my saviour after all. Better quality stereo 48Kbits/sec files (also created by Streamripper) result in the expected 2-channel files. MP4Box takes a 22050Hz stereo file and spits out a single-channel mono file - must be a bug. Actually the files end up a little smaller - it seems that using the above comand, MP4Box is dumping some header information, namely the track title/album information - which to me is a bummer! What do I have to include in the above command to preserve this information?Įdit: Just discovered another problem. I saw your post, tried it and was elated to find that the file sizes and audio quality stay the same. Given that the originals are of low quality to begin with, I find these trade-offs unacceptable.Įnter MP4Box. But much more annoying, despite setting the bit-rate, ffmpeg refuses to encode at anything lower than 59kbits/sec, so I end up with files 3-4 times larger than the originals. The problem with ffmpeg (and re-coding in general I suspect) is that there is a loss in audio quality when I do this. What I have been doing till now is using ffmpeg to recode them, ending up with files that are recognised and have title/album info included. I have lots of Streamripper-ripped aac files that many media players recognise as unknown files, or audio files of zero length, the reason being that Streamripper doesn't include header information with the 'raw' aac data.
