I have Ubuntu 10.04 installed with RoseGarden. Linux Multimedia studio, Audacity and Sound Recorder. 1) Is that all I need to record bass licks and 2) record to DAT or CD? I presently use a four channel Beringer mixer to do it now.
Click to expand...

1) Software-wise, yes. Those applications will give you a number of ways to record. What's the make and exact model # of the audio interface you are using?

2) Ubuntu can burn data and/or audio CDs via Applications-->Sound & Video-->Brasero Disc Burner (one can download more CD/DVD burning utilities from Applications-->Ubuntu Software Centre).

I'm not familiar with recording to DAT but I'd expect that one's PC would need the appropriate digital audio interface plus the software to manage things.

What's the make and model # of your PC?

We can see exactly what your computer's hardware is comprised of if you:

- run sudo lshw in Terminal,

- select the entire output (it'll be lengthy and you may have to drag-scroll to get it all), copy it to the clipboard, and then paste it into a TalkBass post and surround it with
Code: 
 brackets via the  icon in the Reply to Thread menu bar.

Also click the LinuxMusicians link in my sig and see if there's any DAT info there.

...sporting a long list of improvements and the sad news that this well-regarded multi-media GNU/Linux distro's future is uncertain due to a lack of reciprocal support from its multitude of users.

Please read GMaq's comments for details.

AV Linux description
A Linux Distribution for Multimedia Content Creation

AV Linux is a LiveDVD ISO image that is a self-contained, full-featured computer Operating System. It was created using the upcoming Debian GNU/Linux 6.0, LXDE and Remastersys. This LiveDVD ISO image can be downloaded, burned onto any DVD-R(W) and then booted and demonstrated on virtually any recent Windows PC without any effect on the existing OS. If the user desires it can be installed to the Hard Drive as Debian/GNU Linux either on it's own or "dual-boot" with an existing Windows or Linux OS. Once installed AV Linux transforms the user's computer into a full-blown Audio/Video Workstation ready to use! The User Interface features the very lightweight and efficient LXDE 0.5.0 Desktop Environment. It's well-rounded program selection covers most every common everyday computer tasks featuring a full complement of the best F/OSS Multimedia applications and Commercial software demos available allowing users to enjoy Multitrack Audio Recording and Mixing, Video Capturing, Editing and Converting, DVD Authoring and Creation, iPod Tools and much more. AV Linux also contains Hard Drive utilities making it an excellent troubleshooting and rescue solution.

Custom PAE Kernel:
At the heart of AV Linux is a customized i686 2.6.31.12-rt21 Linux Kernel that features "realtime" preemption, 1000hz Timer and PAE (Physical Address Extension) support. This means that even though it is a 32 bit Operating System it is not limited to 4GB of RAM, in fact it can utilize up to 64GB of RAM! This has been done in consideration of those with newer systems many of which come routinely with more than 4GB of RAM. PAE is supported by Intel Pentium Pro, Pentium 3, Pentium 4, CoreDuo and Quad Processors also by AMD Athlon, AthlonXP, X2, and Phenom Processors.

**PLEASE NOTE: Many Pentium "M" mobile processors do not support PAE**
**Check the manufacturers data sheet to confirm whether your CPU has PAE support**

Keep an Older PC Productive:
Computer Operating Systems continue to become more and more resource intensive, many times people upgrade their Operating Systems in the hope of improving their system only to be terribly disappointed when their existing hardware isn't sufficient to even run the supposed "upgrade". PC's have actually been powerful enough for Multitrack Audio and DVD Video Editing since the late 1990's but with the latest Operating Systems wasting precious CPU and RAM on superficial eye candy many potentially productive computers end up being relegated to closets, basements, garages and even worse to garbage dumps and landfills. The chilling legacy of our "disposable" societal mindset is already evident in so-called "tech dumps" in rural China and many other places intentionally well hidden from the comforts of the developed world. By combining the general efficiency of Linux and enhancing it further with a light Desktop Environment like LXDE I consider it an AV Linux mandate to keep older PC's in daily use. I've personally encounted dozens of people who truly believe it isn't possible to build a home recording studio without buying a brand new Mac or PC and spending thousands of dollars on commercial software. The AV Linux LiveDVD serves to demonstrate that this is not necessarily true .

Hardware Support:
In addition to supporting most onboard and common Audio Cards AV Linux also has OOTB Support for many common Pro Audio/MIDI Interfaces like M-Audio, Tascam, Echo and RME. A growing list of Firewire Audio Interfaces are also working with FFADO and FreeBOB. For Video DV Camcorders and other Firewire Video devices (Canopus) as well as many Hauppage Conexxant based Capture Cards are also supported.

Develop, Build, Package:
AV Linux employs the "teach a man to fish" adage. It has been created to assist users in taking the next step and moving from simply using software to building their own software updates if they so desire. If you are an experienced Linux user, packager or developer you will be at home with the large number of development libraries, compilers, build utilities and packaging helper applications available and ready to use. Obtain source code easily through GIT, SVN, BZR, and CVS. Most main applications included in AV Linux have the necessary build dependencies pre-installed for your convenience.

Minimum Requirements:

- Bare Minimum - Intel Pentium 3 or AMD Athlon (XP) 800mhz+, 256mb of RAM+, 12Gig HDD Partition
- Recommended - Intel Pentium 4 or AMD Athlon (XP) 1.8Ghz+, 512mb of RAM+, 40Gig HDD Partition minimum

For those who are thinking of trying AV Linux 4.1 here's a timely how-to re the hard drive partition utility included on the AV Linux 4.1 Live Install DVD (which also includes a well-written and comprehensive manual on AV Linux itself):

The bad news: Ubuntu Studio 10.10 does not have a real time kernel (which is needed to achieve a low latency for recording audio). :(

Real-time kernel

"...The real-time kernel, first included with Ubuntu Studio 8.04, was modified for intensive audio, video or graphics work. The 8.10 release lacks this real-time kernel. It has been reimplemented in the 9.04 release and stabilized with the release of 9.10. 10.04, in contrast, does not include the real-time kernel by default. As of version 10.10, the real-time kernel is no longer available in the repositories.

Typically, computers used as audio workstations rely on hardware monitoring which may provide low latency, but does not allow the live signal to be manipulated beyond available hardware effects. To manipulate a live signal, software processing of the signal is necessary, which most audio work stations can only achieve with latencies greater than several tens of milliseconds. Thus, a notable advantage of the Linux real-time kernel is being able to achieve software processing with latencies well below the human perception threshold of 5 to 10ms.

The scheduler allows applications to request immediate CPU time, which can drastically reduce audio latency[2]. In 9.10, the "Ubuntu Studio Controls" provided under System>Administration permit the user to "Enable Nice," allowing the use of wireless networking and proprietary graphics cards drivers while maintaining low audio latency free of XRUNs (audio drop-outs) in JACK. A more negative value entered for "Nice" reserves more CPU time for real-time audio processes..."

Fortunately AV Linux 4.1 and Ubuntu Studio 9.10 both have a real time kernel. (For the time being one may wish to continue using either of these options or another multi-media distro which has an rt kernel.)

The good news: an affordable, Ubuntu-compatible USB audio interface.

As one would expect it to, this $160.00 CDN, USB bus powered, phantom powered XLR inputs and compressor-equipped, class compliant audio interface works with Mac and Windows.

However, it also works with Ubuntu :):

I will admit that I have not been following this thread very carefully since my last rather disappointing experience.
Has any headway been made in the area that spooked me so badly?
The part of the kernel that can be wrong and cause little problems like cooling fans not turning on?
I really want to give some version of Linux a try, but I don't want to lose another laptop to do it.

Before trying any GNU/Linux distro with any ostensibly Windows-only PC one should Google <the machine's make & model #>, <the GNU/Linux distro & its version> to flush out any hidden gotchas.

Please pay particular attention to the (in Terminal) sudo sensors-detect instruction in post #2 of the following thread (as well as reading through the thread to gain a larger overview of occasional notebook overheating under Ubuntu):

[ubuntu] lm-sensors doesn't show fan speeds
Invalid Link Removed

Next...

Fairly modern computer hardware has sensors which monitor the temperature of various components. By default *lm-sensors...

*"Lm-sensors is a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer systems."

...is installed as part of Ubuntu (it can be found in Synaptic Package Manager).

lm-sensors provides readouts which can be viewed in Terminal. However, I prefer a GUI readout of lm-sensors which is enabled by installing sensors-applet via System-->Administration-->Synaptic Package Manager:

"GNOME Sensors Applet is an applet for the GNOME panel that displays
readings from hardware sensors, including temperatures, fan speeds and
voltage readings.

It can gather data from the following sources:
* ACPI thermal zones, via the Linux kernel ACPI modules
* Linux kernel i2c modules
* lm-sensors (libsensors)
* Linux kernel i8k module (for Dell Inspiron Laptops)
* Linux kernel ibm-acpi module
* Linux kernel PowerPC modules therm_adt746x and therm_windtunnel
* Linux kernel iMac G5 Windfarm module
* hddtemp daemon for reading temperatures from S.M.A.R.T. equipped hard disks
* Linux kernel Omnibook module
* NVIDIA graphics cards (supplied with nvidia-settings)
* Linux kernel sonypi module (for Sony Vaio laptops)

Alarms can be set for each sensor to notify the user once a certain high or low value has been reached, and can be configured to execute a given command at given repeated intervals."

During the installation you will be presented with a dialog with a check box and the question "Should the hddtemp daemon be started at boot?" Check mark the box then click the 'forward' button when prompted.

Once sensors-applet has been installed:

- right-click on a Gnome panel where you wish sensors-applet to display its readings

- select 'Add to Panel...', then select and drag 'Hardware Sensors Monitor' to the desired location (I usually put it on the lower Gnome panel to the left of the Trash icon)

- now right-click on Hardware Sensors Monitor's new icon in the Gnome panel, choose 'Preferences', and then explore the available display options (which will vary depending upon the hardware involved).

Next, please Google around for and install similar hardware monitoring software which will run under Windows. You can then compare the various temperature readouts from both operating systems.

Another approach to monitoring notebook processor cooling fan performance is to listen for when the fan cycles on & off. Said cycles should be the same under Ubuntu as when booted under Windows.
