AAC
Advanced Audio Coding (AAC) is a sophisticated lossy compression audio format developed by MPEG. It's known for its superior audio quality compared to MP3 at similar bitrates, making it a popular choice for digital audio broadcasting, streaming services like Apple Music and YouTube, and mobile devices. AAC utilizes more advanced psychoacoustic models than MP3, allowing for greater efficiency in encoding audio data, often resulting in smaller file sizes for comparable sound fidelity. It supports multi-channel audio and higher sampling rates.
MP2
MPEG-1 Audio Layer II (MP2) is another lossy audio compression standard developed by MPEG. While it predates AAC and is less efficient, MP2 remains widely used in digital radio broadcasting (like DAB and DVB), and on some older audio hardware and consumer electronics. It offers a good balance between compression and audio quality for its time, though it generally requires higher bitrates than AAC to achieve similar perceptual quality. MP2 is simpler in its encoding structure compared to AAC.
为什么转换 AAC → MP2?
You might need to convert AAC to MP2 for several reasons. Older audio equipment or specific broadcasting systems may not support the AAC format, requiring MP2 compatibility. Some video editing software or legacy systems might also be better suited to handle MP2 files. If you are archiving audio for long-term playback on diverse hardware or need to ensure maximum compatibility across a range of devices, converting from AAC to MP2 can be a practical solution. This ensures your audio content remains accessible and playable even on less modern platforms.
AAC vs MP2
AAC and MP2 are both lossy audio compression formats but differ significantly in efficiency and quality. AAC, being a newer standard, generally offers better audio quality at lower bitrates than MP2, making it more efficient for storage and streaming. MP2, while older and less efficient, is known for its broad compatibility with older broadcasting standards and hardware. If compatibility with legacy systems or specific broadcast requirements is paramount, MP2 is the choice. For modern applications prioritizing audio fidelity and file size efficiency, AAC is typically preferred. Converting AAC to MP2 is often done to bridge this compatibility gap.
