equalizer

I have been looking around for creating an audio equalizer using the Web audio API: http://webaudio.github.io/web-audio-api/ I found a lot of threads about creating a visualizer, but that is of course not what I want to do. I simply want to be able to alter the sound using frequency sliders. I found that the biquadFilter should do the work, but I can't get a good result. The sound is altered consistently when I change any frequency value, but it just lowers the quality of the sound while it should alter the frequencies. I first load a sound: Audio.prototype.init = function(callback){ var $this

We are developing a music app using AVPlayer, which is at the end stage. Everything was on track until we started working on iPod Equalizer applying effects to the currents song. We are able to fetch the built in Equalizers list when we apply the AudioUnitProperty we don't see any effects in songs. Your valuable response will be helpful to us. You can most certainly accomplish various EQ effects using an AUGraph and AudioUnits in iOS. Basically, you would insert the effect between the source and the output of your audio. You can use things like a multichannel mixer to have some control, or

Say I have multiple unequal values a, b, c, d, e. Is it possible to turn these unequal values into equal values just by using random number generation? Example: a=100, b=140, c=200, d=2, e=1000. I want the algorithm to randomly target these sets such that the largest value is targeted most often and the smallest value is left alone for the most parts. Areas where I've run into problems: if I just use non-unique random number generation, then value e will end up going under the other values. If I use unique number generation, then the ration between the values doesn't change even if their

I am a newbie in development and I trying to create an equalizer on Android platform. How I can capture output audio stream on android? I just need to take audio information that goes out from my application. (I already searched www.developers.android.com and i have not found any information) There's currently no functionality in Android for recording audio output (well, there's the Visualizer API that let's you grab partial, low-quality audio for audio visualization purposes). If you only need to apply the effect to the audio from your own app then you could do the "recording" internally. I.e

Since a few days, I am trying to create an equalizer using C#. Seen NAudio quite a lot time, but I could not find any working equalizer which would work with naudio. Now after a few days, I am finally here @stackoverflow and hopefully, you know a way to create an equalizer using c#. PS: I've also tried out the System.Media.SoundPlayer. But that SoundPlayer does not even support anything that has to do with dsp. So is there another audio library which works with "pure" audio outside?

I am trying to a small audio songs equalizer. I want to add in it options of treble,stereo like it is in Poweramp player. I implemented equlizer with 5 bands successfully like this:- public class FragmentEqualizer extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) { super.onCreateView(inflater,container,savedInstanceState); equalizer = new EQ(getActivity(), new Equalizer(0,com.androidhive.musicplayer.AndroidBuildingMusicPlayerActivity.mp.getAudioSessionId())); for(Bar bar : eqBars) bar.setActiveEQ(); maximum= EQ
