spectrum into some
number (e.g., 32) of
subbands. The
psychoacoustic model looks at the
energy in each of
these subbands, as well as in the
original signal...
- 320 kbit/s for mono and 512 kbit/s for
stereo streams. It uses 4 or 8
subbands, an
adaptive bit
allocation algorithm in
combination with an
adaptive block...
-
quadrature mirror filters (QMF) to get two
subbands of the signal. When the
ADPCM bitstream of each
subband is obtained, the
results are multiplexed, and...
-
amplitude information of the
subbands of a
modulator signal (such as a voice) and uses them to
control the
amplitude of the
subbands of a
carrier signal (such...
- (generally

leading to
energy levels called "energy
subbands", i.e., the
carriers can only have
discrete energy values. The concept...
- the VIF
index is
defined as VIF = ∑ j ∈
subbands I ( C ¯ N , j ; F ¯ N , j ∣ S N , j = s N , j ) ∑ j ∈

signals are
typically stored in two sub-bands. Note that
signal in odd
subbands is
stored frequency inverted. PQF
filters are used in MPEG-1
