Full spectrogram generation. The main function creates complete visual representations of the spectral content of FLAC files. The process transforms the audio signal into a two-dimensional graph where the X-axis represents time, the Y-axis represents frequencies, and the color intensity indicates the amplitude of each frequency component.
Zoomed spectrogram generation. Allows the creation of spectrograms focused on specific time segments of the audio. Users define the start point and duration of the segment to examine regions of interest with a higher level of detail in the frequency-time domain.
Image dimension configuration. Precise control over the output spectrogram dimensions using width and height parameters in pixels. This customization affects the resolution of the resulting image and the level of visible detail in the spectral representation.
Dynamic range adjustment. Modification of the Z-axis range (dynamic range) to set the lower and upper amplitude limits displayed in the spectrogram. This control determines the visualization's sensitivity to variations in the intensity of frequency components.
Window type selection. Choice between different window functions for Fourier analysis (Hamming, Hanning, Bartlett, Rectangular, Kaiser). Each window type affects the frequency resolution and side lobe attenuation in the signal transformation.
Batch processing. Simultaneous execution of spectrogram generation for multiple FLAC files. The function sequentially processes a selected list of files, applying the same parameter configuration to each one.
Folder scanning. Automatic detection of FLAC files within a specified directory structure. The system recursively traverses subfolders and compiles a complete list of available compatible audio files.
Save configurations. Storage of all spectrogram parameters in external configuration files. Saved profiles retain dimension settings, Z-axis range, window type, and other options for future use.
Load configurations. Retrieval of previously saved parameters from configuration files. This function restores all application settings to a previously defined state without needing to manually re-enter each value.
Integrated preview. Immediate visualization of generated spectrograms within the application environment. The built-in viewer displays the processing result without requiring external software for image viewing.
Color palette configuration. Selection between different color schemes for representing amplitudes in the spectrogram. Each palette assigns specific color combinations to the intensity values of the frequency components.
Audio metadata analysis. Extraction and display of technical information contained in FLAC files. The function shows data such as sampling rate, bit depth, number of channels, and file duration.

The development of RED-Spectrogram began in 2023 as a specialized project for FLAC format audio analysis. The program is created in Python using Tkinter graphical libraries for the user interface. Audio processing is implemented through integration with SoX (Sound eXchange), a command-line tool for sound processing. Development maintains a focus on generating high-precision spectrograms for acoustic analysis and audio quality assessment applications.
