Frank	e0af6f0a94	Bugfix for passthrough did not work because of missing return - for num_channels<=1, "left channel" was still running.. (1 means pass trough)	vor 9 Jahren
Frank	e5df3287eb	Optimize CPU Usage In my testsketch with 2 x Chorus with n_chrous=4 & #define CHORUS_DELAY_LENGTH (24*AUDIO_BLOCK_SAMPLES), Cpu-usage decreases from 13.8% to 9.8%	vor 9 Jahren
Paul Stoffregen	61b271f570	Merge pull request #165 from FrankBoesing/patch-1 Access Q-bit from c	vor 9 Jahren
Frank	cd9eb4b218	Access Q-bitn from c You mentioned in synth_dc.h "// if only C language provided a way to test Q status bit...." Here it is :) . That return (out & 0x8000000)>>27; translates to only one more instruction : ubfx r0, r0, #27, #1 , i decided to use the c -variant because it is better to readable. I added a function to clear that bit ( clr_q_psr() ), too. Unfortunately, three instructions are needed (read-modify-write)	vor 9 Jahren

Frank	6386b79554	don't save r12 indeed..you're right, saving r12 seems to be not necessary. i did some tests, even with gcc 5, all worked. but i'm still only 99.9% sure .-)	vor 10 Jahren
