AAC vs MP2 Format Comparison

Aspect	AAC (Source Format)	MP2 (Target Format)
Format Overview	AAC Advanced Audio Coding AAC is a lossy digital audio compression format designed as the successor to MP3, offering better sound quality at similar bit rates. Widely used in streaming, digital music stores, and mobile devices. Lossy Compressed	MP2 MPEG-1 Audio Layer II MP2 is a lossy audio compression format standardized as part of the MPEG-1 specification in 1993. It offers lower complexity encoding and good resistance to data loss, making it popular in broadcasting applications. Lossy Compressed
Technical Specifications	Sample Rates: 8kHz - 96kHz Bit Rate Modes: CBR, VBR Profiles: LC, HE, HEv2, LD, ELD Channels: mono (1), stereo (2), multichannel (up to 48) Extensions: .aac, .m4a, .mp4, .3gp	Sample Rates: 32kHz, 44.1kHz, 48kHz Bit Rate Mode: CBR only Bit Rates: 32–384 kbps Channels: mono (1), stereo (2) Extensions: .mp2, .m2a
Advantages	High audio quality at the same bitrates as MP3 Supports VBR Low computational complexity for decoding Wide support on modern devices	Low computational complexity for encoding and decoding Robustness to bit errors—suitable for broadcast environments Widely supported in professional broadcasting Simple bitstream structure
Disadvantages	Lossy compression—some audio data is permanently discarded Limited compatibility with older devices Commercial licensing may apply	Less compression efficiency compared to MP3 and AAC Limited support in consumer playback devices Fixed bit rate only (no VBR) Aging format with fewer modern features
Compatibility	Excellent: iOS, Spotify, YouTube, Modern Android devices Good: VLC, Windows Media Player, Modern browsers Limited: Older car stereos, Legacy audio equipment	Excellent: DAB digital radio systems, MPEG-TS streams, Professional broadcast equipment Good: VLC, Foobar2000, Winamp Limited: Most consumer MP3 players, Mobile devices without MPEG-2 support
Common Uses	Music streaming (Spotify, Apple Music) Digital downloads (iTunes Store) Podcasts and audiobooks Audio tracks for video files	Radio and television broadcasting (DAB, DVB) Digital audio delivery in MPEG streams Archiving broadcast content Low-latency live audio applications

Why Convert AAC to MP2?

Converting AAC to MP2 provides a format optimized for broadcasting, offering low-latency and robust error resilience. While AAC excels in streaming and storage efficiency, MP2 ensures compatibility with professional broadcast systems and simple bitstream processing.
