MP3 is a compressed format that reduces file size significantly while maintaining good audio quality, making it ideal for music, podcasts, and web audio. WAV is an uncompressed lossless format that preserves full audio quality, perfect for professional editing and high-fidelity applications.
Higher bitrate (kbps) means more audio data per second, resulting in better quality but larger file size. Sample rate (Hz) determines how many audio samples are captured per second - 44.1kHz is CD quality, while 48kHz is standard for video production. For most uses, 128-192kbps MP3 at 44.1kHz offers excellent quality.
