Transcoding between lossless formats, bitrates, and preserving lossy content 2020-05-29 08:43:58 Hi all,If I have a lossy file and (in lieu of getting a better/lossless copy), would like the file in a different format - what advice can you give regards the conversion?A few examples of the kind of thing i'd like to know - would going up a bitrate retain all of the audio (i.e. 192k AAC > 256k MP3)? Does Stereo vs Joint Stereo in the compressed source or output file matter? Would it be best to convert to a lossless format to retain all of the already-lossy audio?Ignore the 'why' - let's assume an incompatibility between a player and an audio file perhaps.I'm just interested in the differences between popular lossy formats and what happens if you go from one to the other. Will you further lose fidelity, and if so how much? 1%, 10% etc. And also, if you flip back and forth between two lossy formats, will you ultimately end up with a stable/unchanging file or will every conversion yield more and more and more loss? Specific to MP3 - would a 10-15yr old MP3 at 320k be worse/same/better than a modern MP3 rip at 192k for example?I posted this on Reddit to r/audiophile and was advised to check here. I've searched the forums here but not exactly found a post to answer the above.
