Which Audio Format Should You Use?
The right format depends on your use case. MP3 is the most universally compatible format for music and podcasts. WAV offers uncompressed, lossless quality ideal for recording and editing. AAC is preferred for Apple devices and streaming. OGG is open-source and well-suited for web and games. FLAC is lossless compression — high quality with smaller files than WAV.
Will Converting Reduce Audio Quality?
Converting from a lossless format (WAV, FLAC) to a lossy one (MP3, AAC) will reduce quality slightly. Converting between two lossy formats (e.g., MP3 to AAC) may result in cumulative quality loss. For best results, always convert from the highest-quality source file you have.
