Best Audio Format for Storage?

What is the best format settings to store a physical music?

I did look at Flac but the data is almost the same size as the uncompressed Wav and none of my devices or self hosted services seem designed to play flac files. Everything gets converted.

What are people using?

  • I use FLAC for long-term storage, 256kbps Ogg when transcoding for mobile devices.

    Opus is the best lossy codec in terms of efficiency, but many devices/apps don't properly support it.

  • That depends. Are you looking at preserving the music without loss of information? Then you need to use a lossless format like flac. Formats like aac, mp3, opus can throw away information you're less likely to hear to achieve better compression ratios. Flac can't, so it needs more storage space to preserve the exact waveform.

    You can use a lossy format if you want. On most consumer level equipment, you probably won't notice a difference. However, if you start to notice artifacting in songs, you'll need to go back to the originals to re-rip and encode.

  • I'm transcoding everything to 320kbps MP3s. It's much much smaller than flac, and I can't hear the difference even if I try.

  • If I had infinite storage, for archival I’d preferably use FLAC at its default level 5 compression. But like you and others, I thought the file sizes were quite big for a sizeable collection. So my personal compromise was AAC at 256kbps encoded with Apple’s QAAC. It’s small in size, vastly superior to MP3, and almost as universally compatible as MP3. There’s a reason why iTunes has stuck with it for so long, it’s an incredible encoder. I would never be able to hear a difference compared to lossless, at least on my equipment. So I went with it.
