I don't get why one would want to convert _to_ AAC. It's a format both bad and proprietary, thus hardly supported by free software at all. It wins with mp3 only at very low bitrates and is actually _worse_ (although usually within the error margin) than mp3 on high bitrates. If your target machine is anything non-ancient, you want opus, it thoroughly beats both mp3 and aac at any bitrate. Even I, with untrained ears and shitty gear, can ABX 320kbit mp3 on some samples. Never tried with aac but it's said to be similar. On the other hand, pretty few people can ABX opus at just 96k, so encoding at 128k is fine if you're paranoid about quality. Yes, it is that much better. If your target _is_ ancient, you want mp3 for compatibility. You'd need to encode at a crap quality to let aac be significantly better. > but AAC does not present itself as an available target It's patented out of the wazoo. -- An imaginary friend squared is a real enemy. _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
