I have a BEng. degree in Music Technology & Acoustics Engineering and now I am pursuing an MSc in Sound & Music Technologies, both at Technological Educational Institute of Crete, Greece at the Department of Music Technology & Acoustics Engineering. I have been working as a sound engineer (P.A. and Studio) and sound system engineer and designer for the last 8 years. I am very well interested in Digital Signal Processing (Audio related mostly), Acoustics (Electroacoustics, Computational Acoustics, Wavefields, Array Processing) and Sound Computing (NOT Music Computing).

Hello plan_buzz. In general, when one wants to get the impulse response (IR) of a system (at least true for an LTI, but not only that) could use various methods...

Re: Setting 25KHz playback sampling rate in sound card

Reply posted 2 years ago (03/25/2020)
Hello there,Most probably your sound-card does not support "arbitrary" sampling rates. This would either require the use of variable timing clocks (hardware, but...

Re: Inverse FFT of a Sampled Frequency Domain Function

Like drmike said you first of all have to see how Julia implements the routine to make sure you can "compensate" for the magnitude "inconsistencies" (first of all...

Well, first of all bertramaerts is right about this part. Similar to what you do in the second subplot, in the third subplot you should plot only (the first) half...

Hey there Samp17, I am not sure I do understand what the problem might be but I would suggest a couple of "tests" to acquire a better understanding. By delaying...

Hey there,I haven't really delved into the abyss of HRTF-related 3D audio, so I am not sure I can be of too much help but I'll do my best to work it out with you.Regarding...

Hey there Rick,First of all thanks (in advance) for sharing the paper :).So, the most obvious way to do so is to use Acrobat Professional.Additionally as rrlagic...
Well, for your own convenience here is a plot from the code I quoted (apologies for not including labels and titles).Also, here's a nice link showing how overlap-save...
Hey there szak1592, I have to admit I haven't implemented your code and thus I cannot be 100% sure about the reasons it is not working the way it should. Nevertheless,...

Re: linear array beam pattern

Reply posted 3 years ago (04/09/2019)
Well, as for the first part (frequency domain implementation), I'll be honest to say that I am not aware of the method, so I cannot add any insight to that.Regarding...

Re: linear array beam pattern

Reply posted 3 years ago (04/08/2019)
Well, phase unwrapping is not beamforming-specific. It is just a way to interpret phase.For example, if you have two sensors that are lets say 3.5λ apart and you...

Re: linear array beam pattern

Reply posted 3 years ago (04/07/2019)
Hhhmmm, this seems "normal" to me. One subtle point I would like to make (one I had an issue when I was working with beamformers) is to make sure you implement the...

Well, to my understanding, the third step CAN be filtering (I can't think of some property against that statement).In case you would like to implement FIR filtering...

Hey @ctlee,Up to the point you have implemented everything is alright (I assume the fft function pads with zeros if the length of the asked transform is longer than...
Hey nbtech,I am definitely not an expert on the field but what the person who wrote the article actually means is that when phi_1 = 0 and phi_2 = 0, then both the...
