[linux-audio-user] Vocoder Working

by DCZX

Okay, sorted out some file installation difficulties and now it's up! Pretty cool. I wonder if there's a program that can just "stick" a midi note for me though for the carrier... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[linux-audio-user] Miscellaneous hardware/software questions

by Jason White

I am looking for suitable hardware to handle digital i/o between a Linux system and an RME ADI-2 ad/da converter that I just bought. I don't need lots of channels, but reliability of the data transfer is important, including jitter reduction. An RME card would be excellent but it is somewhat outside my budget. Also, connectivity to a laptop would be desirable, suggesting either a USB interface or waiting until http://freebob.sourceforge.net/ (the Alsa firewire project) matures. I don't plan to run any OS besides Linux with this hardware, so Alsa support is crucial. As this is for home/personal use I'm not in a hurry. M-Audio hardware is high on my list of possibilities at the moment. Now to the software question: does there exist any sound editor with a non-graphical interface, i.e., one that can be operated from the Linux console for inserting, deleting, copying and otherwise editing audio? Due to a vision-related disability I can't use a graphical display and therefore need a text-only solution - but all the sound editors appear to require X11. Surely it should be possible to design an audio interface to a digital sound editor. Suggestions welcome. I've discussed hardware on this list once before, and the USB options weren't highly regarded at the time.

[linux-audio-user] hello gentoo? speed up please...

by Aaron Trumm

hello all - got a question - I've only recently been stopping and taking a look at my studio computer's performance and in the almost year since I change from Red Hat 9 to gentoo, it's been more solid on some things, but I notice a huge latency difference - ie: I have to run Jack at -p 8192 to get anything done in Ardour Anybody have any tips on what to look at to tweak it? Seems like it should do better than that... I didn't see it as a problem until in the last few days I started playing with playing softsynths live directly into Ardour - you've gotta be running at -p 1024 or there's a latency that screws up your playing - at 8192 it's a downright 8th note delay... Here's some vitals that I can think of: OS: gentoo 2.6.6-rc1 kernel (alsa built in) jack: 0.99.0 ardour: beta28 jack command line: jackd -R -d alsa -d hw:0 -r 48000 -p 8192 <------- (or whatever) harddrive: multicount on io support: 32 bit unmaskirq on use dma on keepsettings off readonly off readahead on chip: 2ghz amd (I THINK - not at computer now) ram: 512MB thanks for any ideas! :) --------------------- Aaron Trumm www.nquit.com -----------------------

Re: [linux-audio-user] Intel core-duo cpu and realtime patches

by Chris Simpson

i can successfully compile a 2.6.17.6 kernel with patch-2.6.17-rt7, with ACPI disabled within the kernel .config (and from boot just to be doubly sure), but it still won't boot. the chip is exactly the same (intel core duo T2400). what is the difference between the realtime-lsm patch and the MIngo one? chris

[linux-audio-user] customize equalizer for XMMS?

by Florin Andrei

Here's the background: I'm using XMMS-1.2.10 on Fedora Core 5 to listen to various things, mostly MP3 streams from Internet radio stations. I've a nice pair of cans, Grado SR125, that are used for listening. http://www.gradolabs.com/product_pages/sr125.htm The SR125 cans are nice, in fact, they're very analytical and quite revealing. Not exactly best for listening to 128k streams, but hey, that's what I got, that's what I use. The problem: The Grado cans are a bit too harsh for my ears. I very much prefer the Sennheiser HD600 but I'd rather keep the HD600 at home and drag the SR125 at the office to take a beating. The frequency response graph for the SR125 shows some peaks in the mid-high range, which are probably part of the cause for the harshness, and also a cliff in the low frequencies: http://www.headphone.com/products/headphones/all-headphones/grado-sr-125.php I would like to re-create the negative of that graph in an equalizer and apply it somewhere in the chain. I looked at the equalizer that comes with XMMS but there doesn't seem to be a way to create a graph that's so fine-grained. There's only a limited amount of controls that cannot seem to be tweaked. How do I create such a detailed equalizer graph and apply it to XMMS? This machine does not run JACK and I do not intend to change that. I'd like to keep it as simple as possible since, after all, the primary purpose of the system is to do work, not listen to music. Is there any player that can play MP3 streams and has a better equalizer? Any other ideas? -- Florin Andrei http://florin.myip.org/

[linux-audio-user] Fragile!

by Folderol

Is it just me... something about Demudi or? Gnome seems to be incredibly fragile. Almost any configuration change is liable to make it roll over and wave it's legs in the air :( Also... After an epic battle I managed to get Demudi dual booting with Mandrake. Is there a simple way to get Demudi 1.3 on board without upsetting LILO? -- Will J G
