[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 -----------------------

[linux-audio-user] [offlist] Re: Mellotron sounds

by Juhana Sadeharju

>From: Neil Durant <lists(a)sphere3.co.uk> > >I'd be happy to sample the full lengths of all 35 notes for all six sounds, >storing them as wavs. I don't have a lot of spare time these days, so I'll >let someone else have the pleasure of cropping/editing! Please do so. Make the files available from your site or upload to ftp://ftp.funet.fi/incoming/audio/ Note: If we end up to conclusion that the samples cannot be put freely available, then I could make the samples privately available for the following kind of project. Research experts should analyse the sounds and come up with synthesis method which generates as similar sounds as possible. I'm aware of such research teams and I could ask them to analyse the samples. I also have a plenty of research papers on such analysis/synthesis methods. I could place the papers privately available for anyone who wish to write the analysis/synthesis software.

[linux-audio-user] Frontier Design Tranzport working

by Arthur Choung

Hello, I just got a Frontier Design Tranzport and after a little bit of work, I finally got it working with Linux. I was wondering if anyone was interested in knowing how it works and what not. If so, I will put together some documentation and source code and post it somewhere. -Art <arthur_choung(a)yahoo.com> Product Link: http://frontierdesign.com/Products/TranzPort __________________________________ Yahoo!

[linux-audio-user] RMS and peak levels: meters

by Marcos Guglielmetti

What apps can I use to gauge (meter) audio RMS and peak levels? I need yo know exactly the average of peak levels, and the RMS loudness of an audio file. As instance, suppose I want to master my song at a similar RMS level as another audio file has. What should I use? -- Marcos Guglielmetti Coordinador del desarrollo de Musix GNU+Linux (www.musix.org.ar) fecha: sáb oct 29 00:45:01 CEST 2005 ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar

[linux-audio-user] Ardour/TAP reverb problem

by Dave Phillips

Greetings: While recording a session with Ardour I noticed that when I use the TAP reverb any "movement" action such as relocating the playback cursor or moving a region results in a truly horrible noise when the action is completed. Is this a known problem ? Ardour 0.99 (my my own build on Planet C RH9), JACK 0.99. Audio interface card is a Delta 66. Best, dp

[linux-audio-user] software that can rip indices?

by doublehelixer＠yahoo.com

Hello all, I'm having trouble finding an audio utility for linux which can rip individual files using indices on the CD's not just tracks. I have a large library of audio CD's I need to rip, and they all use indices as they all have more than 99 tracks. Can anybody recommend a tool that can handle these? Thanks in advance, - Andy __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[linux-audio-user] Cheesetracker patch

by james＠dis-dot-dat.net

I've written a simple patch to add info on the real-time capabilities of LADSPA plugins in CheeseTracker. I know I seem to be the only CheeseTracker user on the lists, but just in case... http://blog.dis-dot-dat.net/2005/10/cheesetracker-patch.html -- "I'd crawl over an acre of 'Visual This++' and 'Integrated Development That' to get to gcc, Emacs, and gdb. Thank you." (By Vance Petree, Virginia Power)

[linux-audio-user] Only two controls in on usb alsa mixer device

by Alex Polite

I connected my new SB Live External USB to my GNU/Debian Sid box and it "just worked". The only thing that doesn't work is the mixer. In alsamixer only get I one control (PCM). If I start alsa with the -V a option I get two controls (PCM and PCM Capt). So for recording I have no means of setting which source to record from. Beofore I supply you with more detailed diagnostics I just wanted to ask if there are any usual suspects for this problem. alex -- Alex Polite http://flosspick.org - finding the right open source

[linux-audio-user] tool for unpacking .sfArk soundfonts

by Nigel Henry

Hi. Got myself a load of soundfonts from hammerfall. I'm ok for unpacking the .zips and .rar's on my Linux box, but I've never seen .sfArk files before. Is there a tool I can install on my Linux box to unpack these? Nigel.

[linux-audio-user] re:Intel HDA microphone settings

by Geoff Beasley

G'day Markus. I also have a Fujitsu laptop with this soundcard. It seems the problem is the multi-function ports. The I/O on this card can be altered from input status to output depending on what you plug into the socket but this is software driven. I don't know if such features are upported in Linux. I think a post to the alsa-dev list might be in order... let's see who get's to do it first ! cheers, g.
