1. MP3 (MPEG-1 Audio Layer 3):
- MP3 is a digital audio encoding format that compresses audio files to reduce their size without significantly affecting the quality of the sound.
- It was developed by the Moving Picture Experts Group (MPEG) as part of the MPEG-1 standard.
- MP3 files typically have the file extension ".mp3" and are widely used for storing and playing music on various devices.
- MP3 files only contain audio data and do not support video or other multimedia content.
2. MP4 (MPEG-4 Part 14):
- MP4 is a digital multimedia container format that can store audio, video, and other multimedia content in a single file.
- It was developed by the Moving Picture Experts Group (MPEG) as part of the MPEG-4 standard.
- MP4 files typically have the file extension ".mp4" and are commonly used for storing and playing videos on various devices.
- MP4 files can contain audio, video, subtitles, and other multimedia content, making them more versatile than MP3 files.
In summary, MP3 is a digital audio encoding format that compresses audio files, while MP4 is a digital multimedia container format that can store audio, video, and other multimedia content. MP3 files only contain audio data, while MP4 files can contain a variety of multimedia content.

MPEG-1 Audio Layer 3 (MP3)
- Audio-only format designed for efficient compression of digital audio.
- Uses a perceptual audio coding scheme, removing inaudible information to reduce file size.
- Bitrates typically range from 32kbps to 320kbps, with higher bitrates providing better audio quality.
- Suitable for a wide range of applications, including music playback, podcasts, and online streaming.
- Supported by most media players and devices.
MPEG-4 Part 14 (MP4)
- Multimedia container format that allows for the combination of audio, video, subtitles, and other data into a single file.
- Uses various codecs to compress the different components, including H.264 for video and AAC for audio.
- Supports a wide range of video resolutions and bitrates, enabling flexible file sizes and quality levels.
- Ideal for storing and distributing streaming video, digital movies, and TV shows.
- Also used for mobile video playback, web video, and social media sharing.
Key Differences:
- Purpose: MP3 is an audio-only format, while MP4 is a multimedia container format.
- Content: MP3 contains only audio data, while MP4 can contain various media types.
- Compression: MP3 uses perceptual audio coding, while MP4 supports a range of codecs, including AAC.
- File Size: MP3 files are typically smaller than MP4 files, as MP4 contains more data.
- Applications: MP3 is commonly used for music playback, while MP4 is used for streaming video and multimedia storage.
