If i remember the decibel range is bit depth * 6. I play wav file that his bit depth = 16 (using NAudio lib) and I get the fft result then i\'m calc the deci开发者_如何学运维bels for each fft result.
I have an array of audio data I am passing to a reader: recorder.read(audioData,0,bufferSize); The instantiation is as follows:
I have generated the coefficients using FFTW, now I want to reconstruct the original data, but using only the first numCoefs coefficients rather than all of them. At the moment I\'m using the below co
I am currently trying to write some fourier transform algorithm. I started with a simple DFT algorithm as described in the mathematical definition:
Can anybody explain me (simplified) wha开发者_运维问答t happen if I do an image comparison with FFT? I somehow don\'t understand how it\'s possible to convert a picture into frequencies and how this i
I want to process audio offline on iOS, but have a query regarding memory usage. If I use AVAssetRe开发者_如何学Cader to decompress an MP3 to raw PCM data, the memory footprint would be huge. So how w
I am doing a 1D FFT. I have the same input data as would go in FFTW, however, the return from CUFFT does not seem to be \"aligned\" the same was FFTW is. That is, In my FFTW code, I could calculate th
As the title states I\'m using FFTW (version 3.2.2) with Fortran 90/95 to perform a 2D FFT of real data (actually a field of random numbers).I think the forward step is working (at least I am getting
I\'m trying to convert an image to a sound where you can see the image if you were to view the spectrogram of that sound.Kind of like the aphex twin had done in window licker.
I am a student and new to signal processing just few months ago. I picked\"A Novel Fuzzy Approach to Speech Recognition\" for my project (you can google for the downloadable version).
