Common Audio Formats
Common Audio Formats
AIFF (Audio Interchange File Format)
A high-quality, uncompressed format developed by Apple.
Compression: None
Use: Archiving, DJing, editing
Typical settings: 16-bit / 48 kHz
Pros: Lossless, high quality
Cons: Large file size
WAV (Waveform Audio File Format)
Similar to AIFF, WAV is an uncompressed format widely used in professional environments.
Compression: None
Use: Recording, mixing, DJing
Typical settings: 16-bit or 24-bit / 44.1 or 48 kHz
Pros: High fidelity
Cons: Large file size, lacks metadata handling
FLAC (Free Lossless Audio Codec)
A lossless compressed format, which reduces file size without losing audio data.
Compression: Lossless
Use: Archiving, audiophile listening
Pros: Smaller file size than WAV/AIFF, no quality loss
Cons: Not supported by all players
MP3 (MPEG Audio Layer III)
A lossy compressed format designed for size efficiency over quality.
Compression: Lossy
Use: Streaming, casual listening
Typical bitrates: 128–320 kbps
Pros: Small file size
Cons: Loss of audio detail, especially in lower bitrates
Bit Depth: 16-bit vs. 24-bit
Bit depth determines the dynamic range, i.e., how accurately loud and quiet sounds can be represented.
16-bit audio can represent 65,536 levels of loudness. It's standard for CDs and more than enough for most playback use cases.
24-bit audio allows over 16 million levels and is preferred in recording studios for mixing/mastering, where more headroom is needed.
Sample Rate: 44.1 kHz, 48 kHz, 96 kHz
Sample rate defines how often the sound is measured (sampled) per second.
44.1 kHz – Standard for CDs. Captures audio up to ~22 kHz, slightly above human hearing.
48 kHz – Common in video production and DJ tools. Offers better compatibility with modern equipment.
96 kHz – High-resolution format used in studios. Allows more accurate processing and editing but rarely provides audible benefits for casual listening.

Final Thoughts
For most DJs and listeners, 16-bit / 48 kHz files in AIFF or FLAC format offer excellent sound quality. Higher resolutions (24-bit or 96 kHz) are mostly relevant for recording and mastering workflows. MP3s are suitable for casual use but not recommended for professional settings.
