ffmpeg -i input_file.wav -write_id3v1 1 -id3v2_version 3 -dither_method modified_e_weighted -out_sample_rate 48k -b:a 320k output_file.mp3

This will convert your WAV files to MP3s.

ffmpeg
starts the command
-i input_file
path and name of the input file
-
-sample_fmt s16p
sample format. This will give you 16 bit audio (To see a list of supported sample formats, type: ffmpeg -sample_fmts)
-
-ar 44100
Sets the audio sampling frequency to 44.1 kHz (CD quality). This can be omitted to use the same sampling frequency as the input
+
-write_id3v1 1
Write ID3v1 tag. This will add metadata to the old MP3 format, assuming you've embedded metadata into the WAV file.
+
-id3v2_version 3
Write ID3v2 tag. This will add metadata to a newer MP3 format, assuming you've embedded metadata into the WAV file.
+
-dither_method modified_e_weighted
Dither makes sure you don't unnecessarily truncate the dynamic range of your audio.
+
-out_sample_rate 48k
Sets the audio sampling frequency to 48 ksps. This can be omitted to use the same sampling frequency as the input
+
-b:a 320k
This sets the bit rate at the highest rate the mp3 format allows. Reduce this to 160k for mono files.
output_file
path and name of the output file
