MasVisGtk is an audio analysis application designed to examine the technical characteristics of music recordings. It helps musicians, audio engineers and listeners investigate loudness, dynamic range, spectral balance and other properties that influence the sound of a recording.
The application is particularly useful for comparing different masters of the same music. Its measurements can reveal excessive compression, clipping and changes in dynamic range that might not be immediately apparent from listening alone.
MasVisGtk combines graphical analysis with facilities for processing collections of files. This makes it suitable for inspecting individual tracks as well as comparing the mastering characteristics of albums and larger music libraries.
This is free and open source software.
Key Features
- Waveform displays showing amplitude changes throughout a recording.
- Frequency spectrum analysis for examining tonal balance.
- Dynamic range estimation to assess the effects of compression.
- Peak level measurements for identifying excessive signal levels.
- Crest factor analysis comparing peak and RMS levels.
- EBU R128 loudness measurements using LUFS and loudness units.
- Histograms showing the statistical distribution of audio levels.
- Peak-versus-RMS plots illustrating signal dynamics.
- Detect heavily limited and potentially clipped recordings.
- Analyse stereo and supported multichannel audio files.
- Compare the analysis results of different recordings.
- Process multiple audio files in a batch.
- Recursive directory processing for analysing music collections.
- Switch between flat and folder-based file views.
- Export graphical results for further examination.
