The Complete Solution
Signal Generator
Sound level meter


WinAudioMLS is a professional Windows application for powerful real-time signal and system analysis.
WinAudioMLS converts your PC with a soundcard into a professional audio and signal analyzer. By using the PC environment, it is not only a cost efficient replacement for classical laboratory equipment. WinAudioMLS offers more powerful features combined with a comfortable user interface. Typical applications are loudspeaker measurements, repair and design of audio equipment. WinAudioMLS can also be used to adjust PA-systems, judgment of room acoustics, noise measurements or tuning of musical instruments. In addition there are many areas in the industrial measurements e.g. vibration analyis.
Although WinAudioMLS is focused to audio, it has many applications in the area of sub - and supersonic engineering. WinAudioMLS supports industrial measurement cards and reaches an analog bandwidths of DC to 250kHz. The maximum sample rate is 1MHz.

If you run WinAudioMLS on a notebook, you can easily build a mobile measurement system.
WinAudioMLS is widely used for educational purposes.

Most analyzer tools available today do not allow the measurement of a transfer function in real-time. With the unique features of WinAudioMLS you can e.g. directly measure the spatial dependencies of  the transfer function of a loudspeaker by just moving the microphone. The current transfer function will be displayed in real-time.

We offer WinAudioMLS in four basis versions (Light, PRO, PRO EX and LAB see summary table). Each of these versions can be extended with optional plug-ins e.g. 64 channels with 192kHz/24 bits.
