Compress an uncompressed WAV recording down to a 320 kbps MP3 that takes a fraction of the space and plays everywhere. Ideal for moving studio recordings, podcast masters, or sample exports onto phones and shareable platforms.
WAV is uncompressed PCM audio — the same lossless signal a CD or studio session uses. A three-minute WAV is roughly 30 MB versus 7 MB for MP3, but every sample is preserved. Use WAV when you plan to edit, master, sample, or archive the audio and need zero generation loss.
MP3 is the most compatible audio format ever made. It plays on every device built in the last 25 years, from a $5 Bluetooth speaker to a Tesla, and 320 kbps MP3 is sonically indistinguishable from CD for most listeners. Pick MP3 when you want a file that will simply play, everywhere, without anyone asking what a codec is.
