The HidroChannel-UA is a specialized hydraulic channel calculation software developed using MATLAB. This software is designed to facilitate the analysis and design of water flow in hydraulic channels, providing users with accurate computational tools for modeling and simulation. Its intuitive interface and advanced algorithms ensure efficient problem-solving for engineers and researchers in the field of hydraulics.

The rt_script.m is the main program. It generates a text file and a PDF report to log the estimated reverberation time. Two measurement methods can be used: 1) Speaker On-Speaker Off Method, and 2) Balloon Burst Method. The documentation provides basic programs for both methods. It has been found that the Speaker On-Speaker Off Method is significantly more accurate than the Balloon Burst Method. The Balloon Burst Method tends to have over 50% error below 1000 Hz. The reverb_time.m calculates the reverberation time from the 1/3 octave band time logs. Time records of random test signals, generated by the script makelNHANESNoisesm_ed.m (also available on MATLAB Central File Exchange), are ideal for measuring reverberation time using the Speaker On-Speaker Off Method. The Balloon Burst Method can be used to process the same file multiple times to roughly estimate the reverberation time for each 1/3 octave band.

The Linux Soft Real-Time Target is defined by MathWorks for Real-Time Workshop. The target uses the POSIX real-time clock to generate periodic signals, waking up the model process at each time step. The process runs with the highest priority as defined by the scheduler, requiring root privileges to execute. The Linux soft real-time target does not operate as a hard real-time system because the Linux kernel itself is not preemptive. Thus, model execution can sometimes experience delays. The standard Linux kernel preempts every 10 ms. To achieve higher resolution task switching and improve execution precision, one can modify the HZ value in asm/param.h (included in the kernel source code) and recompile the kernel. To include C S-Functions from other directories, place the rtwmakecfg.m file found in this package into the source directory of the C S-Function. The C S-Function must then be processed accordingly.
