Hi David, all, Creating a new thread as the old one was pretty long... On 19/03/2021 15:22, David Kastrup wrote: [...] >> - Zoom H5 shows 4 inputs in jack: the L/R mics and the inputs 1 and 2 > > Oh, can you just put the headphones right next to the mics (makes > astonishingly little difference in comparison to direct connections) and > use jack_iodelay for measuring out the latency of the H5 with your > settings? > > Numbers are surprisingly hard to come by for any audio interface. > This is what I got by connecting jack_delay to one output and putting the headphone right in front of the microphones (connected only one to the jack_delay input). These are common jack settings I use or have used with this device, although the 32 Frames is very unstable and the 64 Frames one gets a few xruns depending on what it's used with (but still more usable). The 128 Frames settings is very stable.

Low recording volume in Pulseaudio

by Antony Gelberg

Hi all, For the purposes of this discussion, I am playing guitar through an Axe-Fx II into a Behringer UMC1820 USB rack soundcard. OS is Xubuntu Focal 20.04. This works fine for general jamming, I can play a backing track from the computer and use the hardware monitoring to mix in the Axe-Fx as necessary. But when I want to record, the levels are low. I record using my Android phone, and activate Audacity to record the guitar tracks from the Axe-Fx. But the levels are so low, the waveform is tiny. I can apply a plugin to increase the volume, but you can imagine the quality. I see the same thing in the Pulseaudio Volume Control Input Devices tab, so it's not an Audacity issue. With jackd active, the input levels are fine, I can see them in Ardour. But I don't want to have to activate jack for more simple stuff like this, it's a pain. For what it's worth, the output level of the Axe-Fx is around 75%, and the input gain knobs on the soundcard at about 25%. Any higher and the clip lights come on when I play hard. Any clues on how to debug / fix this? I'm suspecting a driver issue, because there simply aren't that many moving parts. -- https:/linkedin.com/in/antgel https://resume.antgel.org/ https://about.me/antonygelberg https://antgel.org/

Specifying sample format in ALSA

by Iain Mott

Hello, I'm using Arch Linux (AArch64) for the first time on a Raspberry Pi 4. I need to use HDMI sound and the first HDMI port on the pi is card 0. If I try to use aplay to play a sound file it prints: aplay: set_params:1343: Sample format non available Available formats: - IEC958_SUBFRAME_LE I find that I can play audio through HDMI by specifying the sample format. eg. aplay -D iec958 mysound.wav What I'm stuck with is trying to configure ALSA to make this specification. I've tried the following in my ~/.asoundrc pcm.!default { type plug slave { pcm "hw:0,0" format IEC958_SUBFRAME_LE } } While this produces no Alsa syntax errors when I use aplay, it still won't play the audio and prints: Playing WAVE 'wav48k.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo aplay: set_params:1343: Sample format non available Available formats: - IEC958_SUBFRAME_LE Can anyone please help? Thanks, Iain -- ________ Iain Mott https://escuta.org

online calls with decent auido for music lessons

by Lorenzo Sutton

Hi LAU, As we're entering a 'tighter' lock-down in my area this week I will need to attend online music lessons (bass). The suggested tool is zoom with 'original sound' option selected, but it seems this is not available on Linux (nor in a web (chrome?) client) [1]. In the past setting the 'noise reduction' (or maybe it's echo cancellation) to low seemed to work OK, but I'm wondering if anyone knows of any work-arounds. Or any other platform (Discord seems to use Opus which sounds promising). The one used for the last LAC seemed also quite nice, but I guess that's not free (as in 'gratis')? As zoom is the tool selected by the music school it should also be something relatively hassle-free for the teacher and cross-platform (i.e. assume they will not be on Linux, so no funky stuff like having to install a Mumble server etc. :-| ... Although the offers on mumble.com seem quite reasonable, but has anyone used it for music?) I _am_ already able to set-up e.g. my Zoom H5 (the device not the software) or usb audio interface via JACK to have a decent mic/input at the source and then pulseaudio-jack sink for audio I/O with these apps (I actually helped my son do remote drum lessons which included piping smplayer via jack to him locally and his teacher as well as the e-drum line out with JACK). But of course there's no much point in having decent quality at the source if the software is doing funky stuff like noise reduction and echo cancellation at the source :-| Any suggestion welcome. Lorenzo. [1] e.g. https://www.reddit.com/r/Zoom/comments/g9qu9v/original_sound_and_stereo_opt… https://support.zoom.us/hc/en-us/articles/115003279466-Enabling-option-to-p… [2]

[ANN] Vee One Suite 0.9.21 - An End-of-Winter'21 Release batch #2

by Rui Nuno Capela

Hello twice! The 'Vee One Suite' of 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here and now rolled out as the second batch to the so called 'QStuff*' (northern) End-of-Winter'21 release season. All still delivered in dual form:: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Changes for this 'end-of-season' are as follows: - Fixed an old lurker, causing slight differences to voice on-sets, due to a wrong initial LFO Volume ramping value. - Slightly improved eye-candyness to all graphic widgets, most especially on the EG widget handling, curved lines and gradient fills. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later.

LV2 plugin that controls other plugins?

by Mark Raynsford

Hello! We know that hosts such as Ardour are able to control the parameters of LV2, LADSPA, VST, etc, plugins using MIDI CCs and possibly other automation control signals. Is there a (free, open source) plugin out there that allows for controlling the parameters of a plugin from another plugin? I realize that question's a bit nebulous. I'd like to, for example, have a plugin that exposes a MIDI input. When a NOTE ON is received on that input, it sets the value of a parameter in a different plugin to a given value, and when a corresponding NOTE OFF is received, it sets the value back to something else. Similar actions could be performed from audio signals too, with a bit of math. Ideally I'd like to set up a pile of plugins inside Carla and route control signals between them in various ways like this. Some plugins explicitly expose inputs that allow for control like this, but most don't. I've had a look for plugins that can achieve this kind of general control, but the search terms are so generic that it's a tough thing to search for. It may not even be possible. Anyone know of anything? -- Mark Raynsford | https://www.io7m.com
