Some sort of limiting in AUM [Solved - iOS AGC]

Hi @j_liljedahl or anyone.

I think I’m experiencing some sort of channel limiting effect in AUM. It’s like when one channel peaks the rest lower in volume. But I’m not bussing to a limiter or anything. It’s like it is doing it automatically in the background.

Am I being daft?

    iOS has a built in AGC (automatic gain correction) that kicks in when output level goes above 0 dB. This only happens for built in speakers and headphones etc, not USB audio interfaces. Maybe this is what you're experiencing?

    Interesting. I hadn’t knowingly experienced that before. This was using Bluetooth headphones. That must be it! Thank you.

    That's why you're not getting clipping distortion when the peak level goes above 0 dB.

    Note that if recording in 16 or 24 bit, the recording will clip even if you don't hear it while recording (because of mentioned AGC). 32-bit float recording does not have this problem, since it allows levels above 0 dB.

    Thanks! I will make more of an effort to moderate my modulations… 🙂
