About Audio converter
Change the format of a recording so it plays where you need it. MP3 and M4A suit phones and sharing, WAV and AIFF keep raw uncompressed sound for editing, FLAC is lossless but smaller, and OGG or OPUS are efficient for web and voice. Converting lossy to lossless cannot restore lost detail.
