128 to 320 kbps
128 kbps is efficient for speech. 192 or 256 kbps balances size and sound, while 320 kbps prioritizes music quality when the source supports it.
Verified codec
FFmpeg extracts and encodes the audio, then FFprobe confirms that the result contains a genuine MP3 audio stream and no remaining video track.

Choose 128, 192, 256 or 320 kbps
128 kbps is efficient for speech. 192 or 256 kbps balances size and sound, while 320 kbps prioritizes music quality when the source supports it.
Why 320 kbps cannot repair a poor source
A higher output bitrate reduces additional encoding loss but cannot restore detail missing from the original video. toTube states the output target without claiming to improve the source.

Which bitrate works for music, speech or a car stereo?
For lectures and podcasts, 128 to 192 kbps normally gives clear speech in a compact file. Music benefits more from 256 or 320 kbps when the source is good enough. MP3 remains the safest option for car stereos, USB drives and older players. Compare the result on the device you actually use: a higher bitrate takes more space and is not automatically audible in every listening environment.
Estimate file size from duration
For the same duration, a 320 kbps MP3 is roughly two and a half times the size of a 128 kbps file. One hour of audio is approximately 58 MB at 128 kbps, 86 MB at 192 kbps and 144 MB at 320 kbps, excluding metadata. These are planning estimates rather than guarantees because exact size depends on the encoder and source.
What if the MP3 does not play?
Let the download finish and confirm that the file ends in .mp3. Try a current media player or the browser before converting again. A zero-byte file, implausible duration or saved HTML page points to an interrupted transfer rather than a bitrate problem. toTube checks the final audio stream, but the local transfer can still be stopped by browser settings or insufficient device storage.
Frequently asked questions
Frequently asked questions
01Is the MP3 really encoded at 320 kbps?
When selected, FFmpeg receives a 320 kbps target. The audible result still depends on the source audio.
02Which bitrate is best for speech?
128 or 192 kbps is usually enough for lectures, podcasts and interviews.
03Will the file play on my phone?
Yes. MP3 works with nearly every phone, car system, computer and audio player.
