About MP3 files
MP3 (MPEG-1 Audio Layer III) is a widely used digital audio format that compresses sound files with minimal quality loss, making them smaller for easy storage and streaming. Developed in the 1990s, it became the standard for music sharing and portable players. MP3 uses lossy compression to remove inaudible frequencies, balancing file size and audio fidelity. Though newer formats like AAC and FLAC offer better efficiency or quality, MP3 remains popular due to its universal compatibility across devices and platforms.
About WAV files
The WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM. It stores high-quality audio data without compression, resulting in large file sizes but excellent sound fidelity. WAV is widely used in professional audio production, sound editing, and as a reference format for audio mastering. While not ideal for portable storage due to its size, it remains a standard for preserving audio quality in studios and broadcasting.
