LAoE means Layer-based Audio Editor, and it is a rich featured graphical audio sample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many plugins suitable to manipulate sound, such as filtering, retouching, resampling, graphical spectrogram editing by brushes and rectangles, sample-curve editing by freehand-pen and spline and other interpolation curves, effects like reverb, echo, compress, expand, pitch-shift, time-stretch, and much more… And it is free of charge, under GPL license!

MAnalyzer is an advanced spectral analyzer and sonogram containing unique features such as smoothing, normalization, super-resolution, prefiltering and deharmonization. The included meters provide a peak meter and EBU R128 and ITU-R BS 1770-3 compliant loudness meter.
AnSpec is an analog-style one/third-octave spectrum analyzer AAX, AudioUnit and VST plugin for professional sound and music production applications. It was designed to be a handy visual feedback tool for those who like visual smoothness and easiness of use of analog analyzers. AnSpec also provides peak level indication.
While there are no adjustable parameters available in this plugin, you can still change level meter ballistics and resize plugin’s window.
- 1/3 octave analog-style spectrum analyzer
- Peak level indication
- User interface window resizing
- Stereo and mono analysis
- All sample rates support
- Zero processing latency
- User interface color schemes
- Resizable user interface
- Retina and High DPI support
Audio, video and CD/DVD player that uses DirectShow technology. It can read (but not modify) ID3/Ogg/APE/WMA tags and show sub/srt/aqt/dks subtitles. CD information can be obtained from freedb, CD-TEXT or cdplayer.ini and submitted to freedb.
- custom playback speed, single frame step, capture frame
- you can change subtitles color, size, font, vertical position
- no gap between audio tracks
- save audio to WAV file
- two visualizations – spectrum and oscilloscope
A component to display visualisations and track information on a variety of Logitech LCD screens.
- Support for monochrome LCDs (G13, G15, G510 & Z-10)
- Support for colour LCDs (G19)
- 11 different visualisations (4 spectrum analysers, 4 oscilloscopes, 3 VU meters)
- Track info display
- Massively customisable
Blue Cat’s FreqAnalyst is a free spectrum analyzer plug-in that lets you monitor the spectral content of your audio signal in real time.
This plug-in has been designed to provide extreme smoothness and high resolution for both time and frequency: unlike most spectrum analyzers, Blue Cat’s FreqAnalyst is able to display continuous variations even with a very high frequency resolution, thanks to its unique smooth interpolation algorithms.
Most aspects of the audio to frequency display conversion can be managed, which lets you total control over the monitoring. A special thresholding system has been developed to help you see the important parts of the spectrum easily. In case you need extra precision in a particular frequency range, you can zoom the display and check the part of the graph you are interested in.
This is a “musical spectrum”, displayed accordingly to how the spectrum is divided in music (notes, semitones, etc).
This project is the MATLAB development of a virtual sound level meter. The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods.
Source code requires MATLAB + Signal Processing Toolbox.
Developed under MATLAB R2010a (but might work with some earlier versions)
Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7.
- MATLAB Based Software Sound Analyzer
- Mimics results of an ANSI Standard Integrating Sound Level Meter
- Includes Lp, LEQ, Octave and 1/3 Octave Band, NC, RC and FFT Analysis
