 Audio capture and terminal visualization tool that captures from a microphone and displays a time-\/domain graph that scrolls across your terminal.\hypertarget{index_autotoc_md1}{}\doxysection{Features}\label{index_autotoc_md1}

\begin{DoxyItemize}
\item Real-\/time audio capture from microphone (robust automatic device selection)
\item FFT-\/based frequency analysis
\item Customizable logging options (e.\+g., average sound per tick with peak detection)
\item Terminal-\/based visualization
\item Multi-\/compiler support (GCC, latest available Clang)
\item Debug and Release build configurations
\end{DoxyItemize}\hypertarget{index_autotoc_md2}{}\doxysection{Microphone Device Selection}\label{index_autotoc_md2}
By default, tico automatically selects the most appropriate microphone device using robust heuristics\+:


\begin{DoxyItemize}
\item {\bfseries{USB microphones are preferred}}\+: If a sysdefault device with a USB description is found, it is used automatically.
\item {\bfseries{Sysdefault fallback}}\+: If no USB device is found, any sysdefault device is used.
\item {\bfseries{Final fallback}}\+: If no sysdefault device is found, the standard \char`\"{}default\char`\"{} ALSA device is used.
\end{DoxyItemize}

This logic ensures that USB microphones are prioritized for best compatibility and quality, but the program will work out-\/of-\/the-\/box on most Linux systems with ALSA.

You can override the device selection by specifying the device name with the {\ttfamily -\/d} option.\hypertarget{index_autotoc_md3}{}\doxysection{Prerequisites}\label{index_autotoc_md3}
