Which audio format should I choose?
MP3 plays on every device. M4A (AAC) sounds a little better at the same size and suits Apple devices. OGG is an open format used by some games and apps. WAV and FLAC are lossless: WAV is uncompressed and very large, while FLAC is compressed without losing quality.
For MP3, M4A and OGG you can choose 128 to 320 kbps; 192 kbps sounds transparent for most music. Files are converted in your browser and never uploaded.
