Samplerate of soundcard against USB amplifier

[servimo]

My soundcard suports this samplerates:

$ grep -rH rates /proc/asound | cut -d : -f 2- | sort -u
    rates [0x0]:
    rates [0x160]: 44100 48000 96000
    rates [0x7f0]: 32000 44100 48000 88200 96000 176400 192000

My Amplifier supports more (+)256000, 352800 and 384000, when I use these samplerates, EasyEffects close. The sound continues without EasyEffects.
Is it a problem with EasyEffects? How can I debug this?

I already add these line to environment: PULSE_LATENCY_MSEC=120, is it the latency?

[violetmage]

@servimo can you post a full debug log of the crash(?), using G_MESSAGES_DEBUG=easyeffects ?

Also, what do you mean by amplifier? Is it an all-in-one unit, combining a DAC and an amp? Or something else?

That sounds like the system killing EasyEffects because the audio processing became too heavy in the realtime thread. Which plugin were enabled? Just the convolver?

In any case not all plugins support such high sampling rate values. Look at https://github.com/wwmm/easyeffects/issues/2069#issuecomment-1664800368 for example. So even if we find a way to avoid your system killing EasyEffects most plugins won't work properly at the rate you are trying to use.

Forget it. I did not pay attention to the fact the rate you are trying to use matches the maximum supported by LSP. So the audio processing being too heavy for the system to handle seems like the more plausible explanation. Either that or some limitation in the zita-convolver library.

[servimo]

It's a DAC (Digital-to-Analog Converter), "Moondrop Dawn Pro", I was just doing some tests on it, I always use rate 192000 and plays nice, I will stay with this. The plugin chain is convolver > limiter > level meter, but happen the same if I change convolver to equalizer.

I discovered something, if I disable the "Level Meter" filter, EasyEffects plays at rate of 384000. The one which is using more system resources is "Level Meter" with "Convolver" or "Equalizer" filter enabled. I see this in others predefinitions without using big rates (256000, 352800, 384000). When I use "pw-metadata -n settings 0 clock.force-rate 192000" to force use of 192000 I can enable "Level Meter", but as soon as I force the use of 384000 EasyEffects close.

*I am using this big rates to get the most of my DAC.

When I use "pw-metadata -n settings 0 clock.force-rate 192000" to force use of 192000 I can enable "Level Meter", but as soon as I force the use of 384000 EasyEffects close.

Are you using oversampling in its configuration or just the default options? Oversampling will probably make it use more cpu.

I can't see any oversampling in the configuration of "Level Meter". I am just using "Convolver" or "Equalizer" and "Limiter". Maybe oversampling in the pipewire or alsa configs? Is in the Limiter? Sobreamostragem: nenhuma.

Oops... For some bizarre reason I was thinking about the limiter plugin. That is what happens when we are answering multiple people at the same time :smile:

Just like the autogain the level meter can be quite heavy on resources because it is based on the libebur128 library.

It's ok to close this thread? Thanks for helping me out to find some explanation and possible solutions.

I think it is. There isn't much room to improve this plugin performance.

I reopen this issue just to clarify that the plugins using libebur128 are working nicely with changing in pipewire.conf "default.clock.max-quantum = 8192", witch is the " default.clock.quantum-limit=8192"
