Hi all, i don't know why but with this simple csd i have always same message about 1 sample out of range and always glitches on attack (and strange amp messages!). i have try with 0bdfs = 1 and amp = .25 or no 0dbfs and amp = 10000, but it seems always the same. Please tell me if i'm wrong somethings (i'm really tired and maybe i made somethings stupid in csd). (i'm on windows and, sure, 5.11) Thanks, ciao, fran. |

Hi, Haven't tried it, but it may be due to the balance opcode. It first measures RMS, and since that can't be done instantaneously, there might be a large peak at the attack before the sound is "balanced". Try much smaller amplitudes, which should get rid of this. Or if it serves your purpose, don't use balance and just scale the gain.

Thank Mr. Andrès, i've discovered that i'm missing an optional but basilary parameter for reson opcode (scaling factor)!!! Again thanks, ciao, fran.
