tained for a given output bitrate therefore changes with sample rate.

In the Antex software the bitrate is specified on a per-channel ba- sis. Therefore, requesting 64 kbits/s and stereo will result in a 128 kbits/s compressed MPEG stream. Supported bitrates (per channel) and compression ratios are as follows:

Layer I

32 KHz		44.1 KHz		48 KHz
Bitrate	Compression	Bitrate	Compression	Bitrate	Compression
(kbits/s)	ratio	(kbits/s)	ratio	(kbits/s)	ratio
32	16	32	22.1	32	24.0
64	8.0	64	11.0	64	12.0
96	5.3	96	7.4	96	8.0
		128	5.5	128	6.0
				160	4.8

Layer II

32 KHz		44.1 KHz		48 KHz
Bitrate	Compression	Bitrate	Compression	Bitrate	Compression
(kbits/s)	ratio	(kbits/s)	ratio	(kbits/s)	ratio
32	16	32	22.1	32	24
48	10.7	48	14.7	48	16
56	9.1	56	12.6	56	13.7
64	8.0	64	11.0	64	12.0
80	6.4	80	8.8	80	9.6
96	5.3	96	7.4	96	8.0
112	4.6	112	6.3	112	6.9
128	4.0	128	5.5	128	6.0
160	3.2	160	4.4	160	4.8
192	2.7	192	3.7	192	4.0
224*	2.3	224*	3.2	224*	3.4
256*	2	256*	2.8	256*	3.0
320*	1.6	320*	2.2	320*	2.4
384*	1.3	384*	1.8	384*	2.0

* These bitrates are available for mono files only.

Layer II uses a more sophisticated compression algorithm than Layer I, so it is recommended that Layer II be used wherever pos- sible.
