Re: Resampling problem 44.1 kHz 48 kHz?

there's an option to use zita-a2j/j2a instead of alsa_in/out, which in theory provides better resampling. also note that resampling quality for the cadence aloop bridge is the almost minimum quality, in order to reduce cpu load (because it will likely be running all the time). I should add an optio...

Re: Resampling problem 44.1 kHz 48 kHz?

I reproduced it with Audacity. Generated a sine signal and when choosing ALSA as output, I get crackling. When choosing Jack Audio Connection Kit everything is fine. When stopping Jack and the Alsa Jack Bridge and choosing Alsa in Audacity and the Zoom R8 as Output device everything sounds fine. Als...

Re: Resampling problem 44.1 kHz 48 kHz?

It also happens with the internal onboard sound card, so it's not related to the interface.

Re: Resampling problem 44.1 kHz 48 kHz?

I am online with an ISO image of AVLinux and .... tataaaaaaa... the same. :mrgreen: Either I get distortion while playing youtube videos or I get crackling depending on the sampling rate I choose in Jack. I just downloaded the a youtube file and when paying it through a media player there is no crac...

Re: Resampling problem 44.1 kHz 48 kHz?

The problem is present when listening to youtube videos / music with audible frequencies. Everything sounds metallic and slightly distorted. I have it with 2 PCs and with the KXStudio ISO image. Also appears with Chromium as browser. I'll try the AVLinux image now if it's also present there.

Re: Resampling problem 44.1 kHz 48 kHz?

The problem has to do with the alsa -> jack bridge I guess, because it only happens when using firefox. When I download the file and play it through clementine or smplayer it sounds fine at 48kHz, i.e. without distortion. While in Firefox I get distortion. At 44.1 kHz however I get crackings in yout...

Re: Resampling problem 44.1 kHz 48 kHz?

I just recorded the stream to show what the problem is. When I (only) listen to music in youtube I get crackles or distortion.

Re: Resampling problem 44.1 kHz 48 kHz?

Question. Don't understand the grafic. All are under minus 50 db. Beneath about minus 10db no one can hear it? Ain't it? The frequency I recorded is quite low (~ 30 Hz), that's why it looks a bit strange. But when you listen to the audio files with headphones you can hear it. I just made some more ...

Resampling problem 44.1 kHz 48 kHz?

Hi, I recently had a (unsolved) problem with distorted sounds while playing youtube videos via ALSA -> LOOP -> Jack The thread can be found here: https://linuxmusicians.com/viewtopic.php?f=47&t=16537 if someone is interested. I have KXStudio running and my interface is a ZOOM R8 which is set to 48 k...

Re: Distorted / Crackling Sound via ALSA -> Loop -> Jack

I tried a different interface and I also get the crackling in firefox via youtube. It seems only to happen with the alsa -> loop -> jack bridge. Is there anything that I can test to localize the reason for this? Are the values in alsa config file relevant? My interface works best with 48kHz (which i...

Re: Distorted / Crackling Sound via ALSA -> Loop -> Jack

It happens also with 512 or 1024. When listening to a sinusoidal tone and the problem is present it sounds as there are some higher harmonics overlaying the root tone.

Distorted / Crackling Sound via ALSA -> Loop -> Jack

Hi,

I don't know if this might be related to some software update. From time to time I get a distorted / crackling sound when listening to youtube videos via ALSA-> loop-> Jack. With just Jack everything is fine. Anyone else observed this recently?

Re: Zoom R8/R16/R24

Also what is strange with the R8. It works pretty fine when setting the sampling frequency in CADENCE to 48 kHz. However, with 44.1 kHz I get a crackling tone every some seconds in the playback. With 88.2 kHz this is even worse. I made a test with a DAC nano today and here with 44.1 kHz I didn't spo...
