Currently the limiter only limits if and when the final output to the DAC exceeds the maximum allowed value. It generally doesn't prevent distortion arising from preamp and equalizer. See the discussions here : I propose to change this : The limiter should take action when the output of the DSP exceeds the maximum value, thereby effectively preventing distortions, and that then wouldn't depend on the volume level.
I tried to find out what exactly the limiter does and how it affects distortion. On my Samsung S7 with Oreo and build 823 ( high-res, sampling rate 44.1 kHz, wired headphones ) I chose a song ( mp3, 44.1 kHz ) with a significant amount of bass.Then I activated Tone and EQ and set the bass in both to maximum level, including the eq-preamp. I expected to hear distortions, which would then be diminished after I would have activated the limiter. I would try that both for DVC and non-DVC and didn't expect a difference there. Result : without DVC I heard distorted sound, limiter or no limiter didn't make a difference. With DVC I didn't hear distortions, again the limiter didn't make a difference. Question : Bug or Feature ? I'd say bug : the limiter should have prevented the distortions. That there were no distortions with DVC might be a feature of DVC - but then I'd expect the limiter button to be inactive.
Limiter not working on build 703, and volume sometime feels incosistent. My config : - SoX Resampler (99% Cutoff) - DVC On - Buffers 2x71ms - Dither (Low Shibata Noise Shaping) - Output AudioTrack 16bit/48KHz (Flags 0x10) My phone is Lenovo Vibe K5 (a6020a40) using LineageOS 14.1 Nougat 7.1.2 (20170605-NIGHTLY-A6020), LM Kernel R3 (Linux 3.10.58).
