[music-dsp] Impulse response normalization

2013-11-04 Thread Alessandro Saccoia
Hi all, I can't find any material about impulse reponse normalization for a convolution reverb. Using Logic's space designer I notice that there's definitely a preprocessing of the impulse reponse that one loads: given the same input and impulse without preprocessing, the convolution would

I don't think you have been clear about what you are trying to achieve. Are you trying to compute the sum of many signals for each time point? Or are you trying to compute the running sum of a single signal over many time points? Hello, thanks for helping. I want to sum prerecorded

Good morning Sam, I am really interested in signing up and participating to the seminar if you could setup a webcam, as I cannot come to Barcelona in those days. Could you offer this option? Thank you alessandro On May 31, 2012, at 3:39 AM, Sam Roig wrote: 8/9/10.06.2012 LISTENING AND

Arduino paired with a decent ADC/DAC would be good just for lightweight DSP. It could be used to control a workhorse DSP through I2C communication, but I don't think there is any ready to go development board out there… you should wire it yourself, and program both the processors. alessandro On

Re: [music-dsp] Introducing myself

2012-02-22 Thread Alessandro Saccoia
Hello Bill, I take your question as a chance to introduce myself. When you sweep the input parameter you are introducing discontinuities in the output signal, and that sounds awful. The simplest case to figure that out in your code is imagining that you have the input variable set at 0 (pan =
