[linux-audio-user] powerpc audio distorted unless volume very low

by Matthew Yee-King

Hello I've just got my powerbook back after it took 3 weeks to replace the screen. The repair shop was kind enough to blow away my hard drive and install macos 9.1 so i'm now rebuilding my linux system. I've gone for yellow dog 2.3 (after the debian installer gave me too much gip). Preamble over, heres the griff: I've got kernel version 2.4.19-4a i'm running alsa 0.9rc2 / snd-powermac (rc3 wouldn't build the powermac driver) Some apps work fine, e.g. xmms playing an mp3 (oss emulation) pd 0.35 (native alsa) Others have a very distorted sound unless the software volume level is very low, e.g. audacity (oss emu) SpiralSynthModular (oss emu) 1. has anyone else using ppc noticed this phenomenon of some apps being fine and others being very distorted? 2. does anyone have a good solution? i had the same problem with my previous install on this machine when i had alsa/ benh2.4.19 kernel. the solution i found was to use the 2.4.10 yellow dog kernel + oss native module when running these audio apps. unfortunately this did not allow me to use alsa. cheers matthew

It used very little resources and booted up very quickly. I still have it on the SuSE 6.4 install, so it may still be out there somewhere.

[linux-audio-user] How do you make an ogg?

by Laura Conrad

A technical but mostly non-linux friend was asking me about where Ogg Vorbis is relative to MP3's, given the current status of MP3 encoding software. I did a quick test of making an ogg from a wav, and my naive version produced: [lconrad@tuba renfaire]$ ls -l hercules* -rw-rw-r-- 1 lconrad lconrad 4526080 Aug 18 14:14 hercules2.mp3 -rw-rw-r-- 1 lconrad lconrad 12220015 Sep 3 12:30 hercules2.ogg -rw-rw-r-- 1 lconrad lconrad 49956104 Aug 18 14:09 hercules2.wav I used ecasound to do the encoding, but what my ecasoundrc says it did is: ext-ogg-output-cmd = oggenc --raw -o %f oggenc is: [lconrad@tuba renfaire]$ oggenc -v OggEnc v0.8 (libvorbis rc2) So my question is, is there a way to get the ogg file down closer to the size of the mp3 file? -- Laura (mailto:lconrad@laymusic.org , http://www.laymusic.org/ ) (617) 661-8097 fax: (801) 365-6574 233 Broadway, Cambridge, MA 02139

I forget to mention... The reason it would be good for a dedicated PC Music Workstation is that (even though) you can strip fvwm2 down to just the grey mesh background, you can still have tons of functionality. If you left click on the backdrop, you get the (user defined) pop-up menu with all your favorite scipts, programs, utilities. And if you right click, you get a pop-up menu of all programs that are currently running (click on one to go to that program). Imagine your multitrack recorder on one desktop, then you activate the pop-up menu and choose the mixer to go to your mixer. And that's why you dont need a task bar. Just move from modual to module without pesky task bars, panals or icons lying around taking up valuable space and resources. You can have icons in the pop-up menu if you want to make this more intuitive. Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

[linux-audio-user] Advice for new users?

by Sage

Hello, everyone, I'm new to the list, and to linux audio in general. I tried Linux on my desktop about a year ago, but found it so frustrating that I gave up after a few weeks and reinstalled Windows. But now that Red Hat 8 is out, I'm anxious to try again. The only problem is, I don't know what kind of audio production applications are able to provide me with the functionality that I've been enjoying in Windows with Cubase SX. I have a small home studio with hardware that is fully Linux compatible (bless you, M-Audio). I know Ardour seems to be the best choice for multitrack recording, and I'm sure it would suffice since my plugin needs are limited. Unfortunately, I rely heavily on midi and synth plugins (in my current case, Cubase's VST Instruments) to handle various keyboards. I don't do loops or anything particularly complicated. I just have a simple midi controller that I use to record keyboard tracks. I'd like to hear some suggestions as to what software someone like me could use to retain the same basic functionality when switching to Linux. Does anybody have any suggestions? If people are in general agreement as to what the "best" apps out there are, it might be useful to have a webpage dedicated to recommendations from the list, eh? Just a thought. :) Thanks, everyone. I look forward to hearing your opinions! Sage

[linux-audio-user] Easy question about a single app workstation

by Andy Main

This is my first post on this list, so here goes!...... I've had ardour running on my system for a while now and I really like it. I've now got hold of a second PC which I am gonna dedicate to running only ardour (on a debian system). Now once I have all set up and working well, how would I go about booting directly into ardour? Ie no logins, no fancy window manager just switch on the pc and it boot into it (and mount some drives on a network). I'd for obvious reasons have a dual boot config in order to debug and apt update ;) Thanks for any help given. Andy.

Re: [linux-audio-user] Easy question about a single app workstation

by Andy Main

I use blackbox anyway because I like the minimal approach to things (I use openwindows at work not cde for example). As for the RADAR - I always loved that system, BeOS is my favourite (no flames please!) OS anyway for audio. As for the network drive - its because I have two workstations, I need to transfer data across. I only started this up because I wanted a multitrack only PC - so just to be able to switch on PC and after 20s see ardour without touching anything else would be great! Thanks for the advice anyhoo guys. Andy.

[linux-audio-user] Sweep 0.5.7 -- now with Ogg Vorbis support

by Conrad Parker

Sweep 0.5.7 Development Release ------------------------------- Sweep is a sound wave editor, and it is now also generally useful as a flexible recording and playback tool. Inside lives a pesky little virtual stylus called Scrubby who enjoys mixing around in your files. This development release is available as a source tarball at: http://prdownloads.sourceforge.net/sweep/sweep-0.5.7.tar.gz?download This version includes support for Ogg Vorbis import and export, including both variable and average bitrate encoding modes. There are many other user interface updates, including new input controls for sample rates and channels. There is a new Screenshot tour of Sweep, introducing effects filters, Ogg Vorbis encoding dialogs, and colour schemes: http://www.metadecks.org/software/sweep/screenshots/ Sweep is designed to be intuitive and to give you full control. It includes almost everything you would expect in a sound editor, and then some: * precise, vinyl like scrubbing * looped, reverse, and pitch-controlled playback * playback mixing of unlimited independent tracks * looped and reverse recording * internationalisation * multichannel and 32 bit floating point file support * LADSPA 1.1 effects support * multiple views, discontinuous selections * easy keybindings, mouse wheel zooming * unlimited undo/redo with fully revertible edit history * multithreaded background processing * shaded peak/mean waveform rendering, multiple colour schemes Sweep is Free Software, available under the GNU General Public License. More information is available at: http://www.metadecks.org/software/sweep/ Thanks to Pixar Animation Studios and CSIRO Australia for supporting the development of this project. enjoy :) Conrad.

I use only softsynths on this machine (a laptop with no hardware MIDI support) and they work very well. Rosegarden-4 is probably the nearest thing you'll find to Cubase on Linux now. I say that with some confidence even though it's not at all close to Cubase in professionalism or scope, just because there are so few other music applications on Linux that are designed to be quite so general-purpose and immediately effective. It's not entirely stable or feature-complete yet and we take a somewhat good-enough attitude to latency and performance issues in a way that's entirely suitable for a home musician but not for studio-quality use. But it's entirely possible already to make real music with it, and we'd love more constructive feedback from people who are trying to do that. Rosegarden-4 does quality MIDI sequencing and editing, multi-track audio via JACK with LADSPA plugins (this stuff is fairly new in RG, could use some knowledgeable testers), and good score editing. We've been demoing it at the London Linux Expo yesterday and today and despite the odd crash we've had (I think) pretty productive results. And of course made a lot of noise, most of it rather unattractive. Hey ho. Chris

[linux-audio-user] Fluid question

by Dave Phillips

Greetings: I've downloaded the Fluid soundfont but am unsure how to unarchive it. The file in question is named "FluidR3 GM.sfArk" which implies some sort of archived filetype I don't know about. Can someone tell me what utility I'll need to unarc it ? TIA !
