Frequently asked questions
How much smaller is an MP3 than a WAV?
A 192 kbps MP3 is about a seventh of the size of CD-quality WAV; a 128 kbps MP3 is about an eleventh. Exact sizes depend on the length and sample rate.
Will I hear a difference?
At 192 kbps or higher most people cannot tell an MP3 from the WAV on normal speakers. Keep the WAV if you plan to edit the sound further.
Which bitrate suits podcasts and voice?
128 kbps is plenty for speech. Use 192 kbps for music and 320 kbps when you want the best MP3 quality.
