MP3 and WAV side by side

You start with an MP3 converter to WAV, so the output is already set. Here is what changes in the file.

DetailMP3 compared with WAV
CompressionMP3 is lossy and compressed. WAV is uncompressed PCM: every sample is stored as it is.
File sizeMP3 at 192 kbps is about 1.4 MB per minute. WAV at 44.1 kHz, 16-bit stereo is about 10 MB per minute, seven times more.
MP3 to WAV 44.1kHz 16-bitThe WAV is always 16-bit. Keep the sample rate, or set 44.1 kHz for CD and for most audio editors and samplers.
48 kHzSet 48 kHz when the WAV goes into a video project.
QualityNo quality gain: the WAV sounds the same as the MP3. Detail that MP3 removed does not come back.

  • Why WAV

    Audio editors, samplers, CD burning programs, and some upload forms ask for WAV. They read it with no decode step, and edits do not remove more detail.
