Decoding MP3 to WAV
FFmpeg decodes the MP3 frames and writes them as pcm_s16le samples at the original sample rate and channel count. The WAV sounds the same as the MP3 but is far easier for software to cut, mix and loop because no decoder is needed and every sample is directly addressable.
Typical reasons: a video editor or presentation tool that misbehaves with MP3, an IVR or announcement system needing WAV, or burning an audio CD. A four-minute song becomes roughly 40 MB, so convert only what you need.
Limitations
- The WAV cannot recover detail removed by MP3 compression.
- Systems demanding 8 kHz mono or a specific sample rate need a separate resampling step; this tool keeps the source rate.
- ID3 tags and album art are not carried into the WAV.
Frequently asked questions
Why is the WAV ten times bigger?
MP3 is compressed; WAV stores every sample raw. A 128 kbps MP3 becomes about 1,411 kbps as 44.1 kHz stereo WAV.
Can I use the WAV to burn an audio CD?
Audio CDs need 44.1 kHz, 16-bit stereo. If your MP3 is already 44.1 kHz stereo, which most are, the WAV meets that.
