    Virtual Sound Level Meter

    Virtual Sound Level Meter for analyzing calibrated sound files

    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.

    Umami

    A simple, fast, website analytics alternative to Google Analytics

    Umami is a simple, easy to use, self-hosted web analytics solution. The goal is to provide you with a friendlier, privacy-focused alternative to Google Analytics and a free, open-sourced alternative to paid solutions. Umami collects only the metrics you care about and everything fits on a single page. You can view a live demo here. Umami measures just the important metrics that you care about: pageviews, devices used, and where your visitors are coming from. Everything is displayed on a single, easy to browse page. Umami is able to track an unlimited number of websites from a single installation. You can even track subdomains and individual URLs. Umami is hosted by you under your own domain so you can reliably avoid ad-blockers unlike Google Analytics. The tracking script is tiny (only 2KB) and supports legacy browsers like IE. Umami can be used to host data for friends or clients. Just create a separate account and they can start tracking their own websites on their own dashboard.
