Adaptive Noise Cancellation routine
$100-500 USD
着払い
Need a Windows DLL and source code for an adaptive noise canceller for PCM audio data.
It should be fast enough to operate in real-time for integration into a VoIP application. Common techniques for adaptive noise cancellation include LMS, RMS, neural and other appropriate methods.
The DLL needs to have a routine that can be passed a buffer of PCM voice data in 8000Hz, 11025Hz or 22050Hz (16-bit samples) and adaptively removes/cancels noise from buffer without a significant reduction in voice quality or gain.
A working DLL without source that filters properly for validation purposes should be provided prior to final acceptance of the results and receipt of the source.
## Deliverables
1) Complete and fully-functional working Windows DLL as well as complete source code of all work done.
2) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
3) The total size of the DLL and supporting components (if any) cannot exceed 250KB.
4) The DLL should compile under either GCC or VC if you are using C, Delphi 7 or 2005 are acceptable as well. The size of the complete DLL package should not exceed 250KB. The Intel Performance Primatives can be used provided the entire result with the IPP is smaller than 250KB.
5) The DLL needs to have a routine that can be passed a buffer of PCM voice data in 8000Hz, 11025Hz or 22050Hz (16-bit samples) and adaptively removes/cancels noise from buffer without a significant reduction in voice quality or gain.
