- -out_sample_rate 48k
- Sets the audio sampling frequency to 48 kHz. This can be omitted to use the same sampling frequency as the input.
- -qscale:a 1
- This sets the encoder to use a constant quality with a variable bitrate of between 190-250kbit/s. If you would prefer to use a constant bitrate, this could be replaced with
-b:a 320k
to set to the maximum bitrate allowed by the MP3 format. For more detailed discussion on variable vs constant bitrates see here.
