This method is slow because at every frequency the input has to be stable until the DUT has settled. Basically, timing measurements are based on the analysis of the impulse response measured via MLS. This example shows, that any serious noise measurement must be commented with the weighting curve. On the other hand if you implement a fast filter it has a low frequency resolution. The ParamViewer shows the value in an alphanumeric form and as a bar graph meter.

First start the signal generator and set it to e. For many measurements it is very useful to display helping lines at e. WinAudioMLS measures the ambient noise level and computes the optimal sound level. Sensitive to frequency shifts clock offsets. Supports multiple sound devices. All objects can be moved with the mouse, by dragging it while the left mouse key is pressed. The input is a sine, which frequency is increased in steps from to Hz.
Use a quit environment.
At the end of the short summary, you will find a link to the detailed results. The IMD are very low and with the default settings almost not visible. WinAudioMLS supports up to 16 million points. The A-weighting curve winaudiomos widely used. With the keyboard you can easily zoom and shift the current measurement plot. By using the PC environment, it is not only a cost efficient replacement for classical laboratory equipment.
WinAudioMls: Audio Realtime Analyzer for Windows platform using FFT and MLS
We used the free filter plug-in for the signal generator to create such filter. With the arrow keys you can shift the plot in both winaduiomls. A measurement rectangle is displayed with its default size.
The analyzer contains all core measurement features. The decay rate is entered in dB per winaudiiomls. Measurement via MLS, stopped noise or shots. Move the mouse to the desired position and open the context menu with the right mouse key.
For example, the measurement results can be easily integrated in the documentation processes. This means you can monitor the frequency response with the music signal itself. Attenuation of walls or windows.

We will demonstrate the advantages of MLS techniques with a simple example. It uses a fast attack and an adjustable release. The sizes are displayed in physical values e. Weighting and windowing functions.
At an adjustable time period the spectrogram is updated. With the zoom function, you can select certain frequency ranges.

Typical applications are loudspeaker measurements, repair and design of audio equipment. Modern measurement systems like WinAudioMLS offer a rich set of highly sophisticated measurement techniques.
WinAudioMLS performs an impulse response calculation on both channels simultaneously. WinAudioMLS considers weighting filters, calibration winaudiomps or reference files. A windowing function, typically Blackman, should be applied to attenuate the sidelobes.
