Adaptive speech noise reduction filter software

£250-750 GBP

£250-750 GBP

Paid on delivery
We need digital signal processing software to perform adaptive filtering to remove noise from a microphone signal. The microphone is recording speech in a room, but it also picking up noise (which is also speech) from a loudspeaker in the same room. We have a recording of the electrical signal going to the loudspeaker (i.e. the signal for the noise) and want to use this as the “noise” input to an adaptive filter which will then remove the content due to the loudspeaker from the microphone signal, to leave the desired speech content. The signals are available as WAV files, and we require software (preferably written in high level language – such as C++ or Java, although Matlab or Labview may also be a possibility) to perform the required processing, and store results back to a WAV file (or similar).

Dear Sir or Madam, I would recommend you to use LabVIEW for this kind of project. It has some toolkits that would make the task quite easy and very comfortable to modify/maintain in the future. I work for National Instruments (now as LabVIEW Student Ambassador in Cracow, previously as Applications Enginner in Budapest) and have the highlest level of LabVIEW certification (Certified LabVIEW Architect). I can implement this task in LabVIEW for you if you're interested. Please just send me example .wav files (speech and noise) and I will send you back filtered .wav for FREE as an example. Of course I'm also interested in future cooperation if you need someone for any challenging LabVIEW-related task :) I'm looking forward to hearing from you. Best Regards, Mateusz Owczarek LabVIEW Student Ambassador Certified LabVIEW Architect

I have using several code to do Adaptive noise removal from different signals type i.e. sound, speech and images. I can draft a filter for you in matlab and if you happy about the result I can design it in c++. Please contact me if you need further information.

Hi. I hope you are doing fine I'm an Electrical engineer with a Masters degree in Telecommunications I have 6 yrs R&D experience... I have worked on Gunshot Direction finding using GRAS high sensitvity Mics in which Adaptive filter modelling is very important. I am quite proficient on LABVIEW and i can make a stand alone application for you...I can also wotk on matlab but i have to charge more for that Looking forward to having a detailed discussion thanks

Dear Employer, I am an electrical engineer (MSc degree), and experienced LabVIEW user, I am using it since version 7.2 (2007) I worked at National Instruments as applications engineer, so I have deep insight in LabVIEW and I am a Certified LabVIEW Developer. I have experience with embedded system, signal processing and filter design. I would prefer to use LabVIEW for this project. It has a toolkit called filter design, that makes possible to design realy powerful filters.I can also provide documentation with the code and make for example a video how to use it. What would be the platform of this application? (PC / embedded) Please also let me know, if You would have any questions to me. I am looking forward to work with You. Kind regards, Balazs Nagy

Dear sir, I have done project on adaptive noise cancellation using wiener filter. I have not tried it on real signals like the ones you have but on sinusoidal signals corrupted by noise. I can also try to implement a latest algorithm in adaptive noise cancellation for achiving better results. I prefer simulating the project first in MATLAB and then writing the code in C or required language. I also have experience in Java and a beginner experience in C++.
