DR14 T.meter ~ Linux Dynamic Range Meter

Posted by tom2tec on

DR14 T.meter is a free and open source command line tool for computing the Dynamic Range of your music according to the procedure used in the off-line meter released by the Pleasurize Music Foundation.

This tool is a very useful measure of how loud your music is, and for understanding that a good quality album always has a wide dynamic range, and it’s also useful for understanding the effects of the so called ‘loudness war’.

Dr14 t.meter is released under the terms of the GNU GPLv3 license and is intended for the Linux users who can not use the Windows application released by the Pleasurize Music Foundation, or the plugin for Foobar2000.

I’ve largely tested this application and it has always returned results identical to those of the official off-line meter.

Feature:
  • Compute the DR dynamic range of the audio file

Elisa ~ Simple KDE Music Player

Posted by tom2tec on

Elisa is a music player developed by the KDE community that strives to be simple and nice to use. We also recognize that we need a flexible product to account for the different workflows and use-cases of our users. We focus on a very good integration with the Plasma desktop of the KDE community without compromising the support for other platforms (other Linux desktop environments, Windows and Android). We are creating a reliable product that is a joy to use and respects our users privacy. As such, we will prefer to support online services where users are in control of their data.

FreqTweak ~ Spectral Manipulation & Display

Posted by tom2tec on

FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.

It is an extremely addictive audio toy, but I hope it has value for serious audio work too (sound design, etc). The spectrum analysis is pretty useful in its own right.
