What is a WAV file?

WAV is Microsoft and IBM’s RIFF‑based wrapper for PCM or ADPCM audio. It stores data in little‑endian ‘fmt ’ and ‘data’ chunks, making parsing trivial and ensuring universal DAW support. Introduced in 1991 alongside Windows 3.1’s Multimedia Extensions, WAV replaced raw VOC and AU formats. Its 4 GiB limit was a drawback until RF64 and W64 extensions arrived, but for most pop songs the cap is moot.

What is a MP3 file?

MP3 is the ubiquitous lossy audio format that shrank the music industry onto the early Internet. Employing perceptual coding, it removes frequencies masked by louder sounds, producing acceptable fidelity at 128‑320 kbps. The Fraunhofer team finalised MPEG‑1 Layer III in 1994, but it wasn’t until Winamp (1997) and Napster (1999) that MP3 exploded. Patent pools expired between 2012‑2017, freeing open‑source encoders like LAME. Streaming giants now favour AAC or Opus, yet MP3 remains the safest choice for maximum backward compatibility.
