Re: [music-dsp] Oversized FFT windows --- why so little literature?

It's not done because it causes time-domain aliasing. You can think of the DFT (or FFT) as a sampled version of the continuous frequency DTFT. If the samples aren't dense enough, you get aliasing in the dual domain (the time-domain in this case). This aliasing can be perfectly cancelled during

Re: [music-dsp] Choosing the right DSP, what things to look out for?

Another consideration is whether the DSP supports real hardware floating-point vs fixed-point arithmetic. If you are doing a lot of low level stuff like filters then fixed-point may be fine. But if you are more comfortable with higher level full range floating point then you may prefer a DSP that

Hi everyone, I'm new to this community and I'm looking forward to meeting many like-minded audio "geeks" [cid:19165218-a59c-4cd3-9bca-6a2f43d1604f] I have a new project in mind, which will, for the first time, include a DSP (after having worked with Xilinx SoC FPGAs and general TI and ATMEL
