Digital Audio Speeds

32 kbit/s: AM radio quality
96 kbit/s: FM radio quality
160 kbit/s: low quality music mp3 from web
224 to 320 kbit/s: VBR to highest MP3 quality. 320 kbit/s comparable, virtually indistinguishable to CD quality.

0.8 kbit/s: Minimum necessary for recognizable speech (using speech codecs)
2.15 kbit/s: Minimum bitrate available through the open-source Speex codec
8 kbit/s: Telephone quality (using speech codecs)
32 kbit/s: Lossy audio as used in Ogg Vorbis
256 kbit/s: Digital Audio Broadcasting (DAB) MP2 bit rate required to achieve a high quality signal
400 kbit/s to 1,411kbit/s: Lossless audio as used in formats such as Free Lossless Audio Codec, WavPack or Monkey's Audio to compress CD audio
1,411.2 kbit/s: CD

16 kbit/s: Videophone quality (minimum necessary for a consumer-acceptable “talking head” picture using various video compression schemes)
128 to 384 kbit/s: Business-oriented videoconferencing quality using video compression
1.15 Mbit/s max: VCD quality (using MPEG1 compression)
3.5 Mbit/s typ: Standard-definition television quality (with bit-rate reduction from MPEG-2 compression)
9.8 Mbit/s max: DVD (using MPEG2 compression)
8 to 15 Mbit/s typ: HDTV quality (with bit-rate reduction from MPEG-4 AVC compression)
19 Mbit/s approximate: HDV 720p (using MPEG2 compression)
24 Mbit/s max: AVCHD (using MPEG4 AVC compression)
25 Mbit/s approximate: HDV 1080i (using MPEG2 compression)
29.4 Mbit/s max: HD DVD
40 Mbit/s max: Blu-ray Disc (using MPEG2, AVC or VC-1 compression)
