For example, you may wish to begin playing a note // in response to reading an analog sensor. If you have "velocity" // information, you might start the sample playing and also adjust // the gain of a mixer channel. Use AudioNoInterrupts() first, then // make both changes to the 2 separate objects. Then allow the audio // library to update with AudioInterrupts(). Both changes will happen // at the same time, because AudioNoInterrupts() prevents any updates // while you make changes. // #define AudioNoInterrupts() (NVIC_DISABLE_IRQ(IRQ_SOFTWARE)) #define AudioInterrupts() (NVIC_ENABLE_IRQ(IRQ_SOFTWARE)) // include all the library headers, so a sketch can use a single // #include to get the whole library // #include "analyze_fft256.h" #include "analyze_print.h" #include "analyze_tonedetect.h" #include "analyze_peakdetect.h" #include "control_sgtl5000.h" #include "control_wm8731.h" #include "effect_chorus.h" #include "effect_fade.h" #include "effect_flange.h" #include "filter_biquad.h" #include "filter_fir.h" #include "input_adc.h" #include "input_i2s.h" #include "mixer.h" #include "output_dac.h" #include "output_i2s.h" #include "output_pwm.h" #include "play_memory.h" #include "play_sd_raw.h" #include "play_sd_wav.h" #include "synth_tonesweep.h" #include "synth_waveform.h" #include "multiplier.h" // TODO: more audio processing objects.... // sine wave with frequency modulation (phase) // waveforms with bandwidth limited tables for synth // envelope: attack-decay-sustain-release, maybe other more complex? #endif
