Pete (El Supremo)	9dde3c1926	Add a multiplier (by rheslip)	vor 10 Jahren
robsoles	b78a26f628	add a peak input measuring object deadly simplistic peak difference measuring object, after begin() just goes through samples and find the maximum and minimum signed values, natural behavior of begin() is to reset the max and min, member uint16_t Dpp() returns maximum difference seen and .stop() does what it says.	vor 10 Jahren

Pete (El Supremo)	28a58248d9	My own version of AudioSynthWaveform. Sine is generated with arm_sin_q15() (but is slower) and the other three waveforms are generated without using tables.	vor 10 Jahren
PaulStoffregen	3c31127761	Fix compiler warnings	vor 10 Jahren
Pete (El Supremo)	62698957fb	Add an audio sweep. User defined start and end frequencies and length of time of sweep.	vor 10 Jahren
Pete (El Supremo)	1d58a8e996	Correct storage class of some variables in FIR	vor 10 Jahren
robsoles	f6e459c3a1	Syncing changes to level & volume setting routines I forgot to sync the changes relating to things like 'dac_vol_right(..)' & 'dac_vol_left(..)' removed in favor of 'dac_vol(left,right)' instead; applies to 'volume(..)', 'lo_lvl(..)' & 'dac_vol(..)'.	vor 10 Jahren
robsoles	fcf9987c16	Various corrections and addition of calcBiquad(..); removed 'route(..)' due not easily supportable atm. Updated 'dap_enable(..)' in lieu of route. Fixed dap_audio_eq_band(..) bad use of unsigned. Changed 'updateCoefs(..)' so default behavior is not reset other three elements of state.	vor 10 Jahren
robsoles	f62bd8ef11	Some filter additions, some SGTL5000 additions added AudioBiquadFilter:: public: void updateCoefs(int source, bool noReset); void updateCoefs(int source); added AudioControlSGTL5000:: private: unsigned int modify(unsigned int reg, unsigned int val, unsigned int iMask); public: unsigned int micGain(unsigned int n) { return modify(0x002A, n&3, 3); } unsigned short lo_lvl_right(uint8_t n); unsigned short lo_lvl_left(uint8_t n); unsigned short lo_lvl(uint8_t n); unsigned short dac_vol_right(float n); unsigned short dac_vol_left(float n); unsigned short dac_vol(float n); unsigned short dap_mix_enable(uint8_t n); unsigned short dap_enable(uint8_t n); unsigned short dap_peqs(uint8_t n); unsigned short dap_audio_eq(uint8_t n); unsigned short dap_audio_eq_band(uint8_t bandNum, float n); void dap_audio_eq_geq(float bass, float mid_bass, float midrange, float mid_treble, float treble); void dap_audio_eq_tone(float bass, float treble); void load_peq(uint8_t filterNum, int *filterParameters); void route(uint8_t via_i2s, uint8_t via_dap);	vor 10 Jahren
Pete (El Supremo)	a27b78fc24	AudioSynthWaveform updated to add tone ramping when a tone starts and ends PlayMidiTones example modified to work with ramping.	vor 10 Jahren
