The core team of
nFore Technology has decades of experience in air acoustic physics,
the goal is to pack various acoustic signal processing know-hows
into DSP or easily applicable SoC format. We are also Bluetooth
application specialist and very familiar in Bluetooth profiles and
stack structure.
1. Speech
A. AEC(Acoustic
Echo Cancellation) and Noise Canceller
(1) nFore's
AEC solution is adaptive echo cancellers to remove echo
quickly at the start of call, as well as really full-duplex
solution without echo or voice clipping at the beginning or
end of a double talk voice spurt.
(2)
Dynamically track echo path changes and handle background
noise even in car environment.
B. Microphone
Array
nFore's two
omni-directional microphones solution can is able to remove
unwanted noise for communication applications. Noise can be
no-stationary (e.g. another person's voice) or stationary (e.g.
wind from a fan). It is assumed that the direction of the
microphone is pointed on where the source of the desired signal
is. Sound originating from any other direction is ideally
removed with little to no distortion of the desired signal.
C. Active Noise
Cancellation
nFore's Active
Noise Cancellation technology can be used in noise-canceling
headphone. The performance of the noise canceling is able to
reach 90% reduction which means you'll hear more clear voice
(music) in less plane/train/bus/others noise.
2. Audio Software
Component
A. PowBass
(1)
Bass-boost enhancement solution for headphones.
(2) Although
headphones generally claim to be able to manage the
frequency ranges as low as 20Hz, in practice it is not the
case.
(3) Physical
limitations exist in headphones that make it difficult for
such low frequencies to be produced for the human ear to
hear.
PowBass
utilizes unique human auditory characteristics to reproduce
these low frequencies in a less conventional method, makes human
ears to perceive these sounds.
B. VRSound
(Virtual Reality Sound)
(1) VRSound
is a solution for headphones.
(2)
Reverberation is a familiar concept, enhancing the listening
experience by mimicking the acoustics of your favorite
environment.
(3) VRSound
effectively emulates preset room acoustics and brings your
music to life. Another feature of VRSound for headphone
applications is its ability to "auralize" the sound which
means for more comfortable listening.
C. VSS (Virtual
Stereo Sound)
(1) VSS is a
solution designed for compact-sized speakers.
(2) The step
towards compact-sized multimedia devices in today's markets
naturally reduces the space available for stereo speakers.
(3) The
stereo effect is limited when the physical distance between
speakers is smaller.
(4) VSS
removes such limitations by modifying the sound waves
traveling between the listener and the device to recreate
the stereo effects.
3. Bluetooth
Bluetooth profiles
customization and integration.
nFore also
has the ability to service and support the Bluetooth integration and
all kinds of Bluetooth profiles customization design. following
solutions are successes ported on customer's device
A. Headset/Handsfree
profile
B. A2DP/AVRCP
profile (Source or Sink.)
C. FTP/OPP OBEX
related profile (Server or Client)
D. DUN profile
E. Phone book
solution (GSM07.07 relative commands, Sync., OPP, PBAB profiles)
F. Plug in USB
integration HS/H/F profiles for VoIP solution. (e.g. Skype)
G. 2 Audio
Gateway.
