Convert MP3 to AIFF
What is MP3?
MP3
MP3 uses lossy psychoacoustic compression based on Modified Discrete Cosine Transform (MDCT), reducing audio file size approximately 10:1 by removing frequencies outside human hearing range or masked by louder sounds. Supports constant bitrate (CBR) and variable bitrate (VBR) encoding from 32kbps to 320kbps. Standard CD-quality approximation achieved at 320kbps. Universally compatible across all playback devices and software.
- MP3 encodes audio using lossy compression at various bitrates
- Lossy source limits AIFF quality ceiling—cannot restore removed frequencies
- Sample rate and bit depth preserved or downsampled for AIFF compatibility
- Perceptual coding removes frequencies inaudible to human hearing
- Universal browser and device support—no compatibility concerns
What is AIFF?
AIFF
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format storing PCM waveform data at CD quality (44.1kHz, 16-bit) or higher. Similar to WAV but Mac-native. Large file sizes (10MB per minute at CD quality) but perfect audio fidelity. Converting to other audio formats involves compression decisions.
- AIFF encodes audio using lossless compression at various bitrates
- Lossless audio data provides full fidelity for MP3 conversion
- Sample rate and bit depth preserved or downsampled for MP3 compatibility
