EQUALIZER Audio equalizer GUI
EQUALIZER starts an equalizer for audio input on a PC. This is created as a demonstration of ANALOGINPUT and GUI. It performs real-time power spectral density estimation on acquired audio data and displays them in frequency bins. This may not be how a real equalizer works, so it should be used simply as a demo.
The top panels show the raw audio signals (time series), and the bottom two panels show the spectral densities. Clicking on the panels changes the colors of the signals.
Pressing the space bar (when the window is in focus) shrinks or grows the window to show all 4 panels or the bottom 2 panels. Pressing the escape key closes the equalizer.
It requires the Data Acquisition Toolbox. Also, it may only work on PCs since it uses the winsound adaptor. Because of the high sampling and refresh rate, it may consume significant processing power.
This will only work in MATLAB R14 or later (because it uses nested functions).
Hi I also would like to know how to run this program. I am currently having problems with the analoginput.
is it possible to send the input signal to the audio out port of the PC after some processing using matlab????
Great code,but i also think it's a real-time display of a signal's power spectrum.
Thanks a lot~
It seems to be needs filter. It takes much noise. But it is very good for a DAQ exaple. Thanks
From your description and the comments, it appears that this program is not an equalizer (as understood in the audio industry and referenced by commenter K. Zheng) but a real-time display of a signal's power spectrum. Regardless, it's a useful demonstration of the DAQ toolbox.
i'd like know how to run this excellent program..i need to run it..please send me a e-mail with the details about this.plz plz plz
i'm searching this file for a few days... it works! great!
it seems to be not exactly allocation of code memory with using client side Authentication
It shows perfect behavior.
this code is really great, but if I want to do some change, like adjust each channel's pass coeffients, that is, to add some equalizer filter, what should I do? thanks. email me please
mind helping me? i was actually having a project on this and thanks for the program. its just pls help me in using this thanks
i'd like know how to run this excellent program..i need to run it..please send me a e-mail with the detaiols about this
works great, good job.
For me great program. Congratulations
