MP2 vs TTA
Ein detaillierter Vergleich von MPEG Layer 2 Audio und True Audio Lossless — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
MPEG Layer 2 Audio
Audio FilesMP2 (MPEG-1 Audio Layer II) is an audio compression standard that preceded MP3. It remains the standard audio format for digital radio broadcasting (DAB) and digital television (DVB) due to its lower encoding delay and better error resilience.
Über MP2-DateienTrue Audio Lossless
Audio FilesTTA (True Audio) is an open-source lossless audio codec that provides real-time lossless compression with hardware-friendly decoding. It achieves compression ratios similar to FLAC while maintaining very low CPU requirements during playback.
Über TTA-DateienVorteilsvergleich
MP2 Vorteile
- Robust against transmission errors — designed for broadcast.
- Lower CPU demand than MP3 — mattered for 1990s receivers.
- Universal playback via every audio player.
- ~30 years of broadcast field experience.
TTA Vorteile
- Lossless bit-exact reproduction.
- Fast, low-memory decoding.
- Open-source reference.
- Cue-sheet support.
Einschränkungen
MP2 Einschränkungen
- Worse compression than MP3 at the same quality.
- Largely obsolete for new content.
- Patent licensing never fully cleared (though most expired by 2017).
- Consumer ecosystems chose MP3 and never came back.
TTA Einschränkungen
- Compression ratio worse than FLAC.
- Niche tooling.
- Hardware support died with 2000s DAP era.
- Eclipsed by FLAC.

Häufig gestellte Fragen
MP2 (MPEG Layer 2 Audio) is an audio file format used to store sound recordings — music, voice, podcasts, sound effects. The format defines how the audio samples are compressed (or stored raw), what bitrates are supported, and how metadata such as title, artist, album, and cover art is embedded. It is part of the audio files family.

VLC, foobar2000, and the default media players on Windows and macOS handle MP2 natively. On mobile, iOS Music and Android media apps vary in their support — popular formats work everywhere; niche ones may need a dedicated app. If playback fails on a device, converting to MP3 or AAC usually solves it.

Upload the MP2 to KaijuConverter and pick MP3, WAV, FLAC, AAC, OGG, or any other target. Our FFmpeg pipeline decodes the audio and re-encodes to the target format at sensible default bitrates (VBR ~190 kbps for music, 96 kbps for speech). Metadata and cover art travel with the audio where both formats support them.
MP2 can be lossy or lossless depending on the specific variant. Lossy variants (smaller files) discard some audio detail during compression in ways tuned to be inaudible; lossless variants preserve every sample exactly but produce larger files. For distribution, lossy at high bitrate is standard; for archival, lossless wins.
