Tone Modulation

The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric regular sampling at positive peaks of carrier and... Platforms: Matlab

RTTL2WAV converts a RTTTL-formatted mobile phone ringing tone to a WAV file. A raw pcm output can also be copied to stdout if wanted. This package also includes a simple shell-script name playrtttl. This script plays rtttl stream without using any temporary wav-files. You need a sox frontend... Platforms: *nix

xEQ is a parametric EQ/Tone Control. It consists of Low and High shelf filters and three Peak/Cut filters. It is very useful for placing around distortion effects. Place one xEQ before your distortion effect to act as a preamp's tone control. Place another xEQ after your distortion effect to... Platforms: Mac

Essential HDR is a High Dynamic Range (HDR) tone mapping application. It includes two proprietary tone mapping algorithms: Fast Tone Balancer, for global tone mapping, and, Detail Revealer, for local tone mapping. Both tone mapping algorithms provide superior results and lightning fast... Platforms: Windows, Windows Vista, XPX64, 7

DelayTimeCalculator (DTC) is a simple software designed to help you calculate frequency modulation values in Hertz and delay times in milliseconds for a song tempo in 'beats per minute' or for a frequency value.
