Data Rates
Telephone quality voice:
8000 samples/sec, 8 bits/sample, mono
64Kb/s
CD quality audio:
44100 samples/sec, 16 bits/sample, stereo
~1.4Mb/s
Communications channels and storage cost money (although less
than they used to)
What can we do to reduce the transmission and/or storage costs
without sacrificing too much quality?
