Otolith - Current Projects
is currently involved in several exciting projects in speech and audio
processing. Here is some information about what we're working on.
Please don't ask for the names of our clients, or for confidential
details of these projects, since we protect the confidentiality and
privacy of our clients. All of this information is made public with
the permission of the clients.
Speech research tools
The client is a major developer of workstation-based signal processing
tools and environments for acoustics research, particularly speech.
The client was contacted by a third party, a developer of PC-based
signal processing tools, offering to license the client's product and
distribute a PC-based version. The client had neither expertise nor
manpower to port the product, so they contacted Otolith. We have
worked with both the client and the third party to generate a detailed
specification of the ported product, and we are currently implementing
the first prototype code.
Music effects processing
The client is a manufacturer of high quality music synthesizers, and
desired pitch shifting and bending effects with higher quality output
than the current state of the art. The client contracted Otolith to
develop the algorithms. We have responsibility for the entire
project, from basic research and idea generation through code
development and test. We have delivered prototype versions of the
effects algorithms, and are currently working on real time
Low bit rate speech coding
The client is a startup company, identifying markets and applications
for very low bit rate speech coding, and contacted Otolith to provide
technical support. We have provided survey reports of the current
state of the art, generated innovative techniques for improving
existing algorithms, implemented a selected range of these techniques,
developed demonstration units, and performed experiments to measure
performance. We are currently investigating additional techniques for
improved quality and compression.
