Hello there! I need a software that is able to read WAV files, split each file into an "n" number of chunks, perform FFT to extract the frequency, amplitude and phase of each chunk and then re-synthesize them into a single cycle. I already have a set of tools and papers written in Python that will do most of the job, but I need you to adapt them to my needs. The software needs to run under Mac OS.

Hello, I might be able to help you out here. What are the adaptions you require exactly? The time needed might depend on the size of the tasks. I have a strong background in signal and image processing, having graduated in applied math from UCLouvain. I have a strong experience in Python, NumPy and scientific programming. 4 years experience in the industry in signal/image processing. I work on linux. I have no MacOSX access. If there are no strictly osx specific task that should not be a problem, though, since python is quite portable. Feel free to ask if you need more info. Hope to work together. Alex

Hey, I did something extremely similar for my bachelor thesis - chunking .wav files and applying FFT to them - for that project I have used MatLab, but recently I have worked a lot with Python lately, so I should be able to do it pretty fast. I look forward to hearing from you. Best regards, Ioana

Dear Madam or Sir, I have great experience in Python, C++, Matlab and Java. Moreover, as a mathematician and software developer, I have am familiar with the theoretical as well as the practical part of the Fourier Transformation. Python is exactly the right language for this task if you do not want to do it realtime. Is it true that you it should not performed realtime, i.e. the data is transformed without a delay and without buffering? Moreover, I am a little bit concerned about that the audio file should be chunked, the transformed via FFT into the frequency domain, and the resynthesized. This will produce a lot of artefacts. I would suggest using at least a window function. Furthermore, there are many other open questions that need to be answered to assess you problem: What do you mean exactly by re-synthesizing? Do you want to perform a transformation form the frequency domain back into the time domain (Reverse FFT)? Moreover, what exactly should be done with the frequency, amplitude and phase? Should a transformation be applied before resynthesizing? I am sure that when I understand your requirements I can provide a fast and professional solution. MacOS should not be a problem. If you need a small GUI that you can use with your mouse, that is possible too using Qt for Python. I am looking forward to discuss everything in the chat. Best regards
