MP2 vs VOC
Ein detaillierter Vergleich von MPEG Layer 2 Audio und Creative Voice — 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-DateienCreative Voice
Audio FilesVOC (Creative Voice) is an audio file format created by Creative Labs for Sound Blaster sound cards. It was a dominant PC audio format in the DOS gaming era, supporting multiple data blocks with different sample rates within a single file.
Über VOC-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.
VOC Vorteile
- Retro-gaming archive format.
- Supported by DOSBox and SoX.
- Block-based structure allows streaming.
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.
VOC Einschränkungen
- Legacy — no new content since mid-1990s.
- Limited sample rates (up to 44.1 kHz).
- No metadata.

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.
