Frequently Asked Questions
Apple devices support AAC, MP3, WAV, AIFF, and FLAC natively in the Music app, but OGG Vorbis is not included due to Apple's focus on its own codec ecosystem. Third-party apps like VLC can play OGG on iOS.
Yes. Both OGG Vorbis and AAC (in M4A) are lossy codecs. Converting between them involves generation loss. At high output bitrates (192+ kbps AAC), the quality degradation is minimal.
Basic metadata like title, artist, and album will typically transfer. However, OGG uses Vorbis comment tags while M4A uses iTunes-style MP4 metadata, so some field names may differ or not map perfectly.
Yes. Drag and drop the M4A file into the Apple Music window, or use File > Import to add it to your library. Apple Music will recognize and display the M4A file with full metadata support.
Yes. Android natively supports M4A/AAC. Most Android music players, including Google Play Music and built-in media players, handle M4A files without additional codecs.
FFmpeg encodes the M4A at a standard high-quality AAC bitrate appropriate for the source material. For music, 192-256 kbps AAC delivers near-transparent quality.
