How can I convert my AAC and MP3 audio files to FLAC?
Your mentioning of bitrate and “better than CD” quality indicate that you’re missing out on a couple fundamental bits of info. 1. Compressed audio formats can be categorized as either “lossy” or “non-lossy”. Examples of lossy formats are MP3, Ogg, AAC. These formats actually sacrifice quality in exchange for incredible compression, making the most of limited disk space. Lossy formats have a bitrate associated with them (or a “quality” setting), which allows you to determine what level of trade-off space vs quality is acceptable to you. Non-lossy formats, FLAC for example, do not sacrifice any quality in the transition. They make a perfect digital copy of every bit from the original source. The bitrate is not a measure of quality anymore, it’s simply a measure of how much compression the software was able to achieve, without sacrificing any data. These files are generally much larger than lossy formats, and, in my opinion, the quality issue is negligible (FLAC vs 192kbps ogg, for exampl
