I am converting my old tapes to digital. An album recorded at 43 minutes in length, exported into mp3 seems to be 43 mb. Is that a typical file size? It seems very large to me.
That would be about 430 MB on a CD (i.e. similar to a WAV file). So you’ve gotten about 10-to-1 compression. Pretty typical for mp3. You could set the bit rate lower to get a smaller file but the audio quality would suffer.

1 meg per minute is about average for medium quality MP3 (stereo)
10 meg per minute for CD quality WAV.
