AUDio MEasurement System (AudMeS) is an audio measurement application that uses a computer’s sound card to investigate electrical and acoustic signals. It combines signal generation with visual measurement tools in a single graphical environment.
The application can serve as a basic laboratory instrument for testing audio equipment, investigating frequency response and examining waveforms. Its oscilloscope and spectrum analysis facilities allow users to observe signals in both the time and frequency domains.
AudMeS is particularly useful for enthusiasts, students and engineers who want to perform audio measurements without requiring a dedicated hardware spectrum analyser. Measurement accuracy depends on the capabilities and calibration of the connected audio interface.
This is free and open source software.
Key Features
- Oscilloscope for displaying audio waveforms in the time domain.
- FFT spectrum analyser for measuring frequency components.
- Display harmonic distortion information alongside spectral measurements.
- Signal generator for producing test tones.
- Frequency sweep measurements for investigating frequency response.
- Measure audio signals using conventional sound-card inputs and outputs.
- Support sample rates up to 192 kHz with suitable audio hardware.
- Handle audio interfaces offering resolutions up to 24 bits.
- Graphical controls for configuring generation and measurement tasks.
- Use stereo input and output channels for audio testing.
- Suitable for testing amplifiers, audio circuits and acoustic equipment.
- Cross-platform support – runs on Linux, macOS, and Windows.
