How to convert video to MP3
“Video to MP3” and “extract audio from video” are the same job: keep the words, drop the picture. WaveSmith opens MP4, MKV, MOV, WEBM and writes MP3 or WAV from the same Convert window.
Trim slates and coughs on the wave before you export. The NLE may still want a 48 kHz WAV — use the Video WAV preset. The host wants MP3 — pick Lossy → MP3 in the same dialog.
“Video to MP3” and “extract audio from video” are the same high-intent job. Open the MP4 like a WAV. WaveSmith pulls the soundtrack with FFmpeg on this PC — the picture never has to upload.
How to do it in WaveSmith
File → Open the .mp4 (or .mkv / .mov / .webm).
Step 1 Wait for the waveform. Trim the parts you do not need.
Step 2 Ctrl+Shift+X → Lossy → MP3 (or Video WAV if picture still needs the file).
