Hello.
I found in several websites this paragraph about pitch:
"The ANSI definition of psycho-acoustical terminology says that pitch is
the auditory attribute of a sound according to which sounds can be ordered on a scale from low to high."
My problem is that, I am writing my dissertation for...
I cannot open the elf file from the SDK (working with microblaze), it reads gibberish. Does anyone knows how to read the elf file?
I am trying to read it because I want a pointer to point to my external DDR, I have no idea how to do that, so if anyone knows please help.
Bill.
Hello.
Is it possible to have good conclusions if I perform a pitch tracking algorithm in time domain to voice sampled in 8 kHz or the results will be completely crappy?
Thanks.
Hello.
I am using microblaze. I am confused about the use of floating point numbers.
When in the beginning of the program I select the microblaze, the program asks if I want to have a floating point unit. I answer yes.
So, now I am able to do multiplications with floating points normally? For...
Hello.
I want to do this, however, I don't understand what normalization is.
Also, I don't quite understand how this will produce the pitch from a voice sample.
Can anyone help me here?
Bill.
Hello.
I want to implement a pitch tracking algorithm for voice. Before that, I am implementing the endpoint detection from Rabiner (1981).
In this paper, the energy contour of the audio data is something like the image in the attached file. Rabiner wants to find the beginning and ending of...
I am trying to understand how the algorithm from "An Improved Endpoint Detector for Isolated Word Recognition" from Rabiner, 1981 works but I cannot understand it.
The paper begins with the energy calculation from the previous paper by Rabiner, in 1975 (which, I posted here that I cannot find...
Hello and thanks for the quick answer.
However this is not the paper, I downloaded it and it is just a paper that states the papers that are going to be presented at a conference.
Am I wrong? Perhaps I downloaded a wrong paper? Please tell me if this is the case.
Thanks,
Bill.
Hello.
I cannot find anywhere the paper "An algorithm for determining the endpoints of isolated utterances" from Rabiner and Sambur.
Can anyone upload it or point to it?
I really really need it.
Thank you,
Bill.
But I am not getting any errors in the simulation.
In my code, when my counter reaches zero, I continue to decrease it, until another event comes and reset it to 16 again. It stays that way for many clock cycles.
In the simulation, when the counter is decreasing in the code, it stays zero. It...
Hello.
In VHDL, when I have an integer in a certain range, if we assign to this integer a number that is outside the range, what will happen?
For example, I have this:
signal counter : integer range 0 to 16;
in reset, I assign counter to 16.
and then, in a rising clock edge, I have:
counter...
The next day, it worked without changing anything.
After some debugging, it stopped working again.
So, what is going on? After some use, it gets broken? Is it possible?
