What It Does

DETAAEFilters simplifies getting basic audio filters up and running when using The Amazing Audio Engine. Instead of always using raw C and CoreAudio patterns, DETAAEFilters provides object wrappers for each of the audio filters provided by Apple. E.g. to apply a low-pass filter to a signal, you can simply instantiate DELowPassFilter and set its frequency and resonance values properties.

How It Works

Available Filters

Here is a list of available signal modifiers:

• Bandpass
• Delay
• Distortion
• Dynamics Processor
• Highpass
• High shelf
• Lowpass
• Low shelf
• New Time Pitch
• Parametric EQ
• Peak Limiter
• Reverb
• Varispeed

Example

Below is an example of how to add reverb.

-(void)someMethod {
	self.audioController =
	[[AEAudioController alloc] initWithAudioDescription: [AEAudioController nonInterleaved16BitStereoAudioDescription] inputEnabled: YES];
                                                              
	...

	self.reverbFilter = [DEReverbFilter filterWithAudioController:self.audioController];
	self.reverbFilter.dryWetMix = 50.f;

	[self.audioController addFilter:self.reverbFilter];

	...
}
