<strong>Xruns</strong> For JACK to operate smoothly and without drop-outs it requires that its buffers (the memory used to transport audio) provide a continuous stream of data. Whenever this data fails to arrive in time to satisfy the requests of a JACK app it causes an xrun which is often accompanied by a disruption to the sound output. The key to success with JACK is to eliminate or avoid xruns.

<strong>Buffer</strong> size is measured in frames per second. It determines the latency between the audio being received by JACK and being sent to the output device. The smaller the buffer the lower the latency and, as a result, the higher the accuracy when monitoring audio for multitrack recording. 1024 is the default and is usually a safe value but smaller buffer sizes have less latency, i.e. less delay between the input and output. Try different settings to see how low you can go when recording without getting xruns. The functioning of lower size buffers depends on the power of your CPU and the specifics of your audio device. The lowest buffer most devices can handle well is 64.

If you are familiar with <acronym title="Microsoft">MS</acronym> Windows or OSX already, please be aware that although KXStudio can, in most cases, fully replace these commercial operating systems, it is not intended as a drop-in replacement for either. It is possible to run many <acronym title="Microsoft">MS</acronym> Windows programs under GNU/Linux via a program called Wine, and both Mac OSX and Linux are variants of the UNIX family of operating systems, but the overall GNU/Linux experience is quite distinct. You will have to adjust to the GNU/Linux way of doing things if you want to run KXStudio. Don&#039;t worry about it though because both Windows and Mac users will discover many of their computer skills transfer easily over and getting help online is free and easy.

Although latency mostly refers to buffer size which delays immediate feedback of input, there is additional latency due to the basic processing of your audio interface. There is no way to reduce this “loopback” latency, but its existence will affect the timing of recorded overdubs. To address this, you can tell programs what the delay amount is so that compensation can be made, i.e. the recorded audio will be adjusted in time to account for this delay. Software alone cannot discover what the loopback latency is, so the following procedure is needed to determine the amount of compensation required:

somewhere before the line that says &#039;exit 0&#039;. This command sets the screen brightness to the max value of 7, the lowest brightness setting being 0. The file /sys/class/backlight/acpi_video0/max_brightness tells you what the max setting is.

<p>
It&#039;s important to note that the path to the brightness setting as well as the values used may differ depending on your video hardware. laptop model and display config so you will have to check for the presence of these files and discover their correct locations before modifying rc.local.

Then, after rebooting, I could hold the Fn key and use the up/down arrow keys to adjust my laptop screen brightness. I don&#039;t think the VendorName and BoardName matter too much here and this change should work for anyone using the non-free Nvidia driver on a laptop.

KXStudio includes a program called Wine (Wine Is Not an Emulator) which allows most <acronym title="Microsoft">MS</acronym> Windows software to run under GNU/Linux. It is <acronym title="Free/Libre and Open Source Software">FLOSS</acronym> and does not require a copy of Windows to run it. While a number of Windows applications will not run at all under Wine, there is the odd app or game that runs better under Wine than real Windows! In most cases though, <acronym title="Microsoft">MS</acronym> Windows apps run slower under Wine than under a genuine Windows install. Overall, it is recommended to run native GNU/Linux software instead of using Windows software under Wine, but the option of Wine allows flexibility if no suitable, Linux-native alternative software is available at the moment.

Audio Stream Input/Output (ASIO) is the most common low-latency sound card driver protocol for <acronym title="Microsoft">MS</acronym> Windows, hence most professional Windows audio software is designed to work with ASIO. KXStudio includes WineASIO which provides an ASIO to JACK driver for Wine. This allows ASIO-compatible Windows software running under Wine to access your JACK device/server as if it was an ASIO device.

KXStudio includes the <acronym title="Microsoft">MS</acronym> Windows version of REAPER (Rapid Environment for Audio Production, Engineering, and Recording). REAPER is proprietary software which runs as a fully-functional demo for trial. It is one of the most powerful and popular DAWs available for Windows and Mac OSX, and a native Linux version is in development. REAPER has proven popular under GNU/Linux due to its advanced audio production features, its not-<acronym title="Free/Libre and Open Source Software">FLOSS</acronym>-but-nonetheless-user-friendly licensing and its official support for running the Windows version under Wine.

</p>

<p>
If you are using a 32-bit system, choose windows installer for reaper 32bits and for a 64 bits, choose windows installer for reaper 64 bits.
</p>

<p>
You can simply install reaper by double clicking on the file you just download and follow the steps shown in the window that should opened.
</p>

<p>
Then be really carefull to NOT CHECK rearoute (ASIO driver) installation. Installing rearoute could result in a conflict with WineASIO.

<p>
then don&#039;t forget to register wine as mentionned in the previsous chapter : Registering WineASIO libraries.
