说明： iOS 9通用应用程序，旨在试验音频dsp编程思想。用可重置的计数器数量填充屏幕。计数器速度在计数运行时可变。每个计数器都有一个简单的内置合成振荡器。所有计数器声音都与混响和定制的颤音效果相连。
(iOS 9 Universal app with the purpose of experimenting audio dsp programming ideas. Fills the screen up with a resettable number of counters. Counters speeds are changeable while counting is running. Each Counter has a simple built-in synth oscillator. All Counters sounds are chained with a reverb and custom-made tremolo effect.)

## Counters with Instruments and Tremolo audio effect
This repo is based on Counters with Instruments branch + Tremolo audio effect!
This is a "custom-made" effect subclassing AUAudioUnit. The Tremolo effect algorithm runs is in the function "process" inside TremoloDSPKernel class.
#### Shake the device to randomly change Tremolo rate frequency!
Counter with Instruments has a built-in SimpleSynth playing one note. The notes are randomly generated out of C, E, G notes (C Major chord) in various octaves. Slowing down counters' counting increases reverb wet/dry parameter.
All programmed using AVAudioEngine, AVAudioPlayerNode classes, with code generated soundwaves into AVAudioPCMBuffer buffers, plus AVAudioMixerNode and AVAudioUnitReverb.
