Frequently Asked Questions
What is M4A format?
M4A is a file extension for MPEG-4 audio files, typically using AAC encoding. It's the standard audio format for iTunes and Apple Music, offering better sound quality than MP3 at similar bitrates.
Is M4A the same as AAC?
M4A is a container format that typically contains AAC-encoded audio. While AAC is the codec, M4A refers to the file format used primarily by Apple. M4A can also contain ALAC (lossless) audio.
What bitrate should I use?
256 kbps is the standard for iTunes Store and Apple Music, offering excellent quality. 192 kbps provides very good quality for most listeners. 320 kbps offers near-transparent quality.
Will converting from FLAC to M4A lose quality?
FLAC is lossless while M4A with AAC is lossy, so there will be some quality loss. However, at 192 kbps or higher, the quality loss is minimal and imperceptible to most listeners.
What devices support M4A?
M4A is natively supported by all Apple devices, iTunes, most Android phones, and modern media players. It has excellent compatibility across devices and platforms.
