What bit rate is required to equal the quality of FM radio?

[TheZMan]

“Thus = 12 x 30,000 x 2 (2 channels) = 720Kbps (CD is 1411kbps) that is uncompressed.”

The table below can help you estimate the kind of mp3 quality/compression and bit rates to use for your own applications. We also give you approximate file sizes to help you compare.

Format	Bit rate	Compression ratio	File size per minute	Notes
WAV	uncompressed	1:1	10 MB	If the wave wav file was sampled at 16 bits/44.1kHz, you've got CD quality sound
MP3	160 kbps	9:1	1.5 MB	Very low compression, superior sound quality
MP3	128 kbps	11:1	1 MB	The standard "CD quality" bit rate
MP3	96 kbps	15:1	700K	Considered "near CD quality"
MP3	64 kbps	22:1	400K	About the same quality as an FM radio station
