Re: [linux-audio-user] Installing Demudi packages on Debian

by David Baron

When Debian started calling their "kernel" stuff "linux" stuff, there was a kernel-source/kernel-image-2.6.12 from demudi on Sid (maybe I had a Demudi reference in sources.list). I tried it. Installed, ran, same error messages as Debian's linux-image-2.6.12s. Have not seen it on Sid lately.

[linux-audio-user] Xruns at the end of a take

by Ruben Lopez

I'm still fairly new to Linux audio and trying to understand things like Xruns, but I've got Ardour (0.99) working and am able to record tracks from Hydrogen. But at the end of every take, I get a single Xrun - "XRUN callback (1) - alsa_pcm:xrun of at least 2.026 msecs". I only get this when I stop recording, never during the take, and I only get one right around 2.0x ms. I've raised the latency but it I still get the Xrun every time I stop the transport. Now I've learned that Xruns are a bad thing, but since I am getting it when I stop the transport, does that mean that the recorded tracks should be good... or do all Xruns happen at the end of a take?

[linux-audio-user] 192kHz

by Carlo Capocasa

Hi, I've been planning to buy an RME MultiFace sound adapter for quite some time now, but now I see all these 192kHz devices on the market. My question, how useful is 192kHz for practical purposes? How quickly is that likely to change? I'd really appreciate some advice here, thank you. Carlo

Recompile and make > sure it's disabled (it should have been disabled by default). Saw nothing about activating either in .config -- both are modules. I blacklisted genrtc in the hotplug/usb stuff and now I have rtc neto. Maybe this is not the place but it worked.

[linux-audio-user] Correct way to start alsa newer kernels?

by David Baron

I have three scripts in /etc/init.d: 1. alsa, apparently deprecated 2. aslasound, claims to be the right one 3. alsautils. I am not (according to webmin) doing any of these on startup. The two audio drivers, snd-ens1371 and usb-audio load anyway (not by hotplug that lists them as already loaded). Only options on these is "index" and they load in the desired order in any event. The snd-mpu401 does not load No error message. This one has "options". Alsasound does not reference options, just the sound-card-# lines to find drivers. It looks for a snd-...... file in init.d. I made one for the mpu401 to modprobe it with its options. As I said, alsasound is not being run. I can modprobe this manually just fine. Apparently, starting with 2.6.12? options not checked? Apparently, starting with 2.6.14, I need to on my system anyway, compile in the soundcore to get anything to work.

[linux-audio-user] Noise gate (or something else?)

by Mikhail Ramendik

Hello, I desperately need a noise gate, or something else to remove breathing sounds. Could anyone help me find one? I am recording using Audacity 1.2.3 from a rather simple microphone, and breathing sounds are clearly heard when the speaker inhales air; from the look of the graph, it seems that a simple noise gate would remove them. But I could not find a noise gate in Audacity 1.2.3... Is there any program, including a plugin for or later version of Audacity, taht would do noise gating? Or perhaps there is a better way to remove the sounds? (There is a Noise Removal plugin, but might it not affect the voice itself?) -- Yours, Mikhail Ramendik
