We have a project that uses the FT and takes in an array from a WAV file and outputs the same array(16 bit) as a filtered WAV file (HP, LP, BP or BE). This is in C# and can be provided. We want a new routine (with the same IO as the existing one) that uses a good FFT. If a better (faster) commercial product is available we would like to compare it, but the preference is for a free one (eg Code Project).
Also we would like software that would produce an envelope output from the same WAV file and output it as a WAV file but at a lower sample rate. It should have the same IO as the above FFT.
Hi there, I would like to discuss more the project, More about me: Full stack application development for more than 15 years of professional experience of corporate grade applications in technologies that inc Daha Fazla
