WAV vs MP3: What Every Beginner Should Know
If you have never converted audio before, here is the essential background. WAV is what your recording software saves by default — it is uncompressed, perfect quality, but enormous. A single 3-minute song can be 30–50 MB.
MP3 is the compressed version. It uses a clever trick called perceptual audio coding — it removes sounds the human ear cannot easily detect (very high frequencies, sounds masked by louder sounds). The result sounds nearly identical but is 5–10x smaller.
When should you convert WAV to MP3?
- You want to share a track via email or messaging — WAV is too large
- You are uploading to SoundCloud, YouTube, or a streaming platform
- You want to load tracks onto your phone without filling up storage
- You are a DJ preparing a USB drive for a gig
- You are exporting a podcast episode for distribution
When should you keep WAV? When you are still editing, mixing, or mastering — always work in WAV and convert to MP3 only for the final output.
