The Filtered Noise Generator (FNG) can generate noise signals and apply different frequency filters on them in real time. Applications are loudspeaker or general audio testing, tinnitus masking, audio cross-over development, etc. Features include: White and pink noise signals with adjustable crest factor; Preset storage and recall; Multi sound card support;
This program is an audio analyzer with FFT and n-th octave frequency analyzers and oscilloscope. The octave analyzer can show the frequency spectrum at 12th, 6th, 3rd and full octave resolution. (A standard license supports all resolutions). With the FFT frequency analyzer you can see the spectrum on a linear scale, which can be useful for harmonics and other analysis tasks. Also on board is a real time oscilloscope.
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 hardware devices costing several thousand dollars or Euros. Here the computer sound card supplies the two signals to the two channel amplifier.
The Test Tone Generator (TTG) turns the PC into a function generator for testing or demonstration, sound tuning, education or for sound effects. Features include: Constant and swept tones; many wave forms (Sine/square/triangle/white and pink noise with adjustable crest factor etc.); Extensive scripting including a Script Editor; Preset storage; Change the frequency in real time seamlessly by keyboard, mouse or slider; Multi sound card support.
Sample Champion is a powerful real-time software tool designed for high precision acoustic measurements. With Sample Champion you will be able to measure the Impulse Response of a room, or analyze loudspeaker Frequency Responses using the MLS (Maximum Length Sequence) method. It has been designed for acoustical technicians, sound engineers, scientists and students. Sampling rate up to 192 kHz, 24 bit support. FFT length up to 64K points.
It has shown that a person who takes the iq test for Mensa admission twice often has a better result at the second time. Up to 20 units more. It has been explained with that they by then are used to the test situation and the nature of the problems. As this iq test is made very equal to Mensa's iq test I hope you will get used to it so you can come closer to your top result at the first time.
Perform audio, acoustical and vibrational measurements user-friendly, accurate and flexible using a sound card. WinMLS2000 is widely used by professionals. Now low-cost versions allow the amateur to perform professional loudspeaker and room measurements User friendliness is ensured through default setups for the standard measurements (e.g. sound system calibration, THD+N and harmonic distortion, reverberation time in rooms.
Zeta Test is an integrated test management environment that enables you to perform black-box tests, white-box tests, regression tests or change management tests of software applications. Zeta Test helps you to plan, perform, log, monitor and document the tests, and then to evaluate the test results. Create and manage your test cases and test plans with Zeta Test. Test your software with test scripts that you created with Zeta Test.
AnyDbTest is declarative style testing tool. We need not to program any more. What we do is to express what we want to test, rather than how to test. We only need to write an Xml test configure file to tell AnyDbTest what we want to test. Rather than painstakingly writing test code for xUnit test framework. So AnyDbTest is the right choice for DBA or DB developers.
Test Controller is a free, hosted test management tool offering test management support via Internet Explorer and Mozilla Firefox. It allows you to record and execute your tests, link them to requirements and track your execution results release-by-release. User access is controlled via a range of privileges. Extensive reporting and charting is provided. Test Controller is backed up with free support and a comprehensive user manual.
