Reading this answer here and questions like:
...has made me really wonder about whether I'm handling my music in the most efficient way; whether I'm converting my music collection to too high a bitrate.
At the moment, my strategy for my music collection is pretty crude; I download the songs from my YouTube playlists (using youtube-dl) in the best quality M4A versions available, and then mass-transcode those to a bitrate of 192kbps using Format Factory. If any of the downloaded files are already 192kbps or below, then I leave them as is.
I'm wondering whether forcing all my M4As to 192kpbs or below in this way is the most efficient way to go. Is it possible that 192kbps is wasteful/inefficient - that M4A files can tolerate much lower bitrates while retaining the same quality - or is this entirely dependent on the bitrate of the file and/or other factors? I'm wondering how everyone else approaches this situation. Also, while I'm at it, if the encoding/transcoding experts can spot any other point of my working process where I might be sabotaging the quality of my files, I'd really appreciate that being pointed out to me.
