Strobe Sync Pulse Generator
By Timo Esser
This program generates signals to test loudspeakers with the help of a synchronised LED stroboscope. The only external hardware needed is a two channel amplifier and an LED flashlight. Traditionally these tests are done with dedicated, inflexible hardware devices costing several thousand dollars or Euros. In this program the computer sound card supplies the two signals to the two channel amplifier. The speaker signal (sine wave on the left channel) is amplified and sent to the loudspeaker under test. The other signal is the light trigger pulse on the right channel. It is sent to the external trigger input of a stroboscope or it can also be amplified and sent directly to LEDs. A standard LED flashlight (British English: torch) is ideal as a stroboscope.

DSSF3 Basic
By Yoshimasa Electronic Inc.
The free version of the advanced sound measurement software DSSF3 is now available. It consists of the signal generator, sound recorder and player, and the peak level meter. DSSF3 Basic works with the latest soundboards. Two or more soundboard can be selected easily. The sampling rate can be set up to the maximum value allowed by the hardware. Signal Generator spec Tone, noise, sweep and pulse is generated as a stereo signal. As for tone, sinusoidal, triangle, square, and saw-tooth wave can be chosen. Each channel can generate different signals with specified frequencies. As for noise, white and pink can be chosen. Sweep is a tone signal of which frequency is varied continuously. Pulse signal is generated with specified number of time, duration and interval. Recording and Playback Recording of sound up to about 10 minutes is possible. Playback of the recorded sound can be measured by the FFT analyzer (Spectrum, octave analysis, oscilloscope, ACF IACF measurement) simultaneously.
Juno-Nemesis Remix
By Mountain King Studios Inc
Juno Nemesis is a 3D shooter in the style of Tempest and Gyruss with modern 3D graphics. Set inside the cyberspace of a huge and powerful computer called Juno, the player must defend the machine from a virus program designed to destroy the system. Six levels or constructs must be saved by destroying 30 waves of the attacking bugs. 12 power-ups , 3 weapon types , bonus items and extra bolt-on weapons are introduced over the 30 waves until the final showdown with the Nemesis itself.
