&lt;h2&gt;Install Wine&lt;/h2&gt;
&lt;p&gt;Wine is a software that enable .exe software to run on UNIX systems such as Linux or Mac OS.&lt;/p&gt;
&lt;h3&gt;On Debian and derivatives (Ubuntu...)&lt;/h3&gt;
&lt;p&gt;Enable 32 bit packages (if you haven't already):&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;sudo dpkg --add-architecture i386
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Download and install the repository key:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-key add winehq.key
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Add the repository to /etc/apt/sources.list or create a wine.list under /etc/apt/sources.list.d/ with the following content:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;&lt;span class="k"&gt;deb&lt;/span&gt; &lt;span class="s"&gt;https://dl.winehq.org/wine-builds/debian/&lt;/span&gt; &lt;span class="kp"&gt;buster&lt;/span&gt; &lt;span class="kp"&gt;main&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Update packages&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;sudo apt update
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Install Wine stable&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;sudo apt install --install-recommends winehq-stable
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;h3&gt;On Fedora, RHEL, and derivatives&lt;/h3&gt;
&lt;p&gt;Add repository :&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;dnf config-manager --add-repo https://dl.winehq.org/wine-builds/fedora/33/winehq.repo
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Install stable package :&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;dnf install winehq-stable
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;h2&gt;Install Kaleidoscope&lt;/h2&gt;
&lt;p&gt;Kaleidoscope is available on both fedora and debian based distros at &lt;a href="https://www.wildlifeacoustics.com/"&gt;wildlife acoustics&lt;/a&gt;.&lt;/p&gt;
&lt;h2&gt;Install Syrinx&lt;/h2&gt;
&lt;p&gt;As all following softwares, Syrinx is not available for GNU/Linux, we need Wine to execute the &lt;code&gt;.exe&lt;/code&gt;.
Syrinx-PC is available at &lt;a href="https://drive.google.com/file/d/0B5ZM90wrDzUOM0ZfYlpDR2l1cU0/view"&gt;Google Drive&lt;/a&gt;.
You will also need the config files available at &lt;a href="https://drive.google.com/file/d/0B5ZM90wrDzUOQnBhRjNVRFM1Rkk/view"&gt;Google Drive&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;You have almost two options :
You can either right click on the &lt;code&gt;.exe&lt;/code&gt; installer and select &lt;code&gt;Open with other application&lt;/code&gt; and &lt;code&gt;Wine Windows Program Loader&lt;/code&gt;, or either run &lt;code&gt;wine syrinxalphainst.exe&lt;/code&gt; in Terminal.&lt;/p&gt;
&lt;h3&gt;Set up app launcher&lt;/h3&gt;
&lt;p&gt;You have to create a new file &lt;code&gt;.local/share/applications/syrinx.desktop&lt;/code&gt;:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;&lt;span class="k"&gt;[Desktop Entry]&lt;/span&gt;
&lt;span class="na"&gt;Type&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Application&lt;/span&gt;
&lt;span class="na"&gt;Encoding&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;UTF-8&lt;/span&gt;
&lt;span class="na"&gt;Name&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Syrinx&lt;/span&gt;
&lt;span class="na"&gt;Comment&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Acoustic analysis&lt;/span&gt;
&lt;span class="na"&gt;Exec&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;/usr/bin/wine /home/&amp;lt;USER&amp;gt;/.wine/drive_c/Program\ Files\ (x86)/syrinx/Syrinx.exe&lt;/span&gt;
&lt;span class="na"&gt;Icon&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;/home/&amp;lt;USER&amp;gt;/.wine/drive_c/Program Files (x86)/syrinx/img/vigie-chiro.png&lt;/span&gt;
&lt;span class="na"&gt;Terminal&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;false&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;Change &lt;code&gt;&amp;lt;USER&amp;gt;&lt;/code&gt; by your username. To have the icon, you can download &lt;a href="images/vigie-chiro.png"&gt;&lt;code&gt;vigie-chiro.png&lt;/code&gt;&lt;/a&gt;.
To analyse ultrasound, with a 384 kHz sampling frequency, we have to open &lt;code&gt;Configs_syrinx/exp384.dsp&lt;/code&gt;; and next Load sound file (&lt;code&gt;Ctrl+L&lt;/code&gt;). To switch to other sound file in same folder, we can use &lt;code&gt;alt+arrows&lt;/code&gt;. For more tips, you can view &lt;a href="https://www.youtube.com/watch?v=BPPSw2FSLxs"&gt;the video of Charlotte ROEMER (Fr)&lt;/a&gt;.&lt;/p&gt;
&lt;h2&gt;Install and Configure Batsound 4&lt;/h2&gt;
&lt;p&gt;The procedure is quite similar with Syrinx-PC installation.&lt;/p&gt;
&lt;h3&gt;Set up app launcher&lt;/h3&gt;
&lt;p&gt;Create a new file &lt;code&gt;.local/share/applications/batsound.desktop&lt;/code&gt;:&lt;/p&gt;
&lt;div class="highlight"&gt;&lt;pre&gt;&lt;span&gt;&lt;/span&gt;&lt;code&gt;&lt;span class="k"&gt;[Desktop Entry]&lt;/span&gt;
&lt;span class="na"&gt;Type&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Application&lt;/span&gt;
&lt;span class="na"&gt;Encoding&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;UTF-8&lt;/span&gt;
&lt;span class="na"&gt;Name&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Batsound&lt;/span&gt;
&lt;span class="na"&gt;Comment&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;Acoustic analysis&lt;/span&gt;
&lt;span class="na"&gt;Exec&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;/usr/bin/wine /home/&amp;lt;USER&amp;gt;/.wine/drive_c/Program\ Files\ (x86)/Pettersson/Batsound4/BatSound.exe&lt;/span&gt;
&lt;span class="na"&gt;Icon&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;/home/&amp;lt;USER&amp;gt;/.wine/drive_c/Program Files (x86)/Pettersson/Batsound4/img/batsound.png&lt;/span&gt;
&lt;span class="na"&gt;Terminal&lt;/span&gt;&lt;span class="o"&gt;=&lt;/span&gt;&lt;span class="s"&gt;false&lt;/span&gt;
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;
&lt;p&gt;(Do not forget to change &lt;code&gt;&amp;lt;USER&amp;gt;&lt;/code&gt; to your username.)&lt;/p&gt;
&lt;p&gt;To have the icon, you can download &lt;a href="images/batsound.png"&gt;&lt;code&gt;batsound.png&lt;/code&gt;&lt;/a&gt;.&lt;/p&gt;
&lt;h3&gt;Configure Batsound to analyse ultrasounds&lt;/h3&gt;
&lt;ul&gt;
&lt;li&gt;Enter the &lt;code&gt;Sound/Sound Format&lt;/code&gt; menu.&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img alt="Entering Sound/Sound Forma menu" src="images/batsound/enter-sound-format-menu.png"&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Change &lt;code&gt;Time expansion&lt;/code&gt; value to 10 (according to your recorder settings)&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Keep 44 100 as &lt;code&gt;Samples per second&lt;/code&gt; value.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Enter the &lt;code&gt;Analysis/Spectrogram Settings - Defaults&lt;/code&gt; menu.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;&lt;img alt="Entering Spectrogram Setting - Defaults menu" src="images/batsound/spectrogram-settings-default-values.png"&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;Change &lt;code&gt;Max frequency&lt;/code&gt; to &lt;code&gt;150000&lt;/code&gt;;&lt;/li&gt;
&lt;li&gt;Set &lt;code&gt;Amplitude color mapping&lt;/code&gt; to &lt;code&gt;Yellow, Red &amp;amp; Blue&lt;/code&gt;;&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Adapt &lt;code&gt;Threshold&lt;/code&gt; to sound intensity.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;You can zoom in.&lt;/p&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;With a &lt;em&gt;Pipistrellus kuhlii&lt;/em&gt; record, I obtain the following spectrogram with the above settings :
&lt;img alt="pipkuh spectro" src="images/batsound/pipkuh-spectro-batsound.png"&gt;&lt;/p&gt;
&lt;h2&gt;Install 7-zip&lt;/h2&gt;
&lt;p&gt;7-zip is useful in Vigie-Chiro process to compress audio files for faster upload to &lt;a href="https://vigiechiro.herokuapp.com"&gt;https://vigiechiro.herokuapp.com&lt;/a&gt;.&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Download &lt;code&gt;.exe&lt;/code&gt; installer at &lt;a href="https://www.7-zip.org/"&gt;https://www.7-zip.org/&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Execute &lt;code&gt;7z1900.exe&lt;/code&gt; with wine.&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Install Lupas-Rename&lt;/h2&gt;
&lt;p&gt;Lupas-Rename is used in Vigie-Chiro protocole to batch rename audio file to add protocoles informations such as pass and square.&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Dowload &lt;code&gt;.exe&lt;/code&gt; installer at &lt;a href="https://rename.lupasfreeware.org/download.php"&gt;https://rename.lupasfreeware.org/download.php&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;Execute installer with wine&lt;/li&gt;
&lt;li&gt;Batch rename audio files...&lt;/li&gt;
&lt;/ol&gt;
&lt;h2&gt;Conclusion&lt;/h2&gt;
&lt;p&gt;With all these functionnal softwares, you are able to perform Vigie-Chiro protocole and sound analysis on GNU/Linux. I look forward to see your participation at &lt;a href="https://vigiechiro.herokuapp.com"&gt;https://vigiechiro.herokuapp.com&lt;/a&gt; !&lt;/p&gt;</content><category term="audio"></category><category term="bat"></category><category term="bird"></category><category term="ultrasound"></category><category term="syrinx"></category><category term="batsound"></category></entry></feed>
