how to video to mp3 for speech and meetings
- drop a video from your device onto the box above.
- optionally set start and end to keep only one part.
- choose mp3 (or another format) and a bitrate; tick mono for speech.
- press extract audio and download the file.
for speech, 64 kbps mono at 22 khz keeps the voice clear and makes a file of about 0.5 mb per minute. an hour-long lecture comes to roughly 29 mb instead of 85 mb at 192 kbps stereo. the preset also lifts the volume by 3 db, which helps with quiet meeting recordings.
most transcription tools accept mp3 and perform as well on 64 kbps mono as on high bitrates. if the recording has music or you need to hear fine detail, switch to 128 kbps and stereo.

frequently asked questions
will speech still sound natural?
yes. 64 kbps mono is above the quality of an old phone call and fine for listening and transcription.
can i make it louder?
the volume slider goes up to +12 db. very high values can distort loud parts, so raise it a few db at a time.
what about a long meeting?
trim off the waiting time at the start and end with the sliders. the conversion takes less time than the recording.
