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.
TurboBass Express is a precise tool, developed to specifically design a cabinet to perform in the confines of a car boot tuned to cope with road noise And internal pressure. No other program I know of will perform this specific task. All you need is a technical data sheet from the manufacturer of The mid range, woofer or sub woofer. You only need three of the parameters to Calculate the desired cabinet needed.
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.
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.
